                            VOLUME II.



          [Illustration: (Printer's Mark) ALERE FLAMMAM.

This volume contains our account of all the Orders of Birds met with
within the Argentine Republic except the Passeres, which were treated of
in the First Volume. It also comprises an Appendix and Index, and
completes the work. The Introduction is issued with this, but is
intended to be bound up with the first volume, and is paged to follow
the contents of that volume.

The total number of species which we have thus assigned to the Argentine
Avifauna is 434. To this list, no doubt, considerable additions will
have to be made when the more remote provinces of the Republic have been
explored. We trust that this work may at least serve to excite residents
in Argentina to make fresh investigations, for we are quite aware how
imperfect is the compilation now offered to the public.

It will be seen that in the following pages, as in the first volume, we
have availed ourselves liberally of the information on Argentine birds
contained in the writings of Dr. Burmeister, Mr. Barrows, and Mr.
Gibson. To all of these gentlemen we wish to offer our most sincere
thanks, together with apologies for the liberty we have taken. We have
likewise to express our high estimation of the valuable notes which we
have extracted from the published writings of the late Henry Durnford
and Ernest William White, both most promising Naturalists, and both
alike lost to Science at an early age. Nor must we omit to record our
thanks to Hans, Graf von Berlepsch, of Münden, Mr. Walter B. Barrows,
and Mr. Frank Withington, and other friends and correspondents who have
aided us by information and by the loan of specimens.

To the Zoological Society of London and to Mr. Henry Seebohm we are
likewise much indebted for the loan of the woodcuts of which impressions
are contained in these volumes.

Of the great American family Trochilidæ, which, according to the most
recent authorities, contains about 450 species, eleven members have been
ascertained to occur within the limits of the Argentine Republic. But of
these only three (_Calliperidia furcifera_, _Hylocharis sapphirina_, and
_Chlorostilbon splendidus_) reach the neighbourhood of Buenos Ayres,
where they occur as summer visitors. The remaining eight have been met
with only in the northern and western provinces of Argentina. Of these
two (_Oreotrochilus leucopleurus_ and _Patagona gigas_) are also found
in Chili, the others are Bolivian and South-Brazilian species.



  +Oreotrochilus leucopleurus+, _Scl. et Salv. Nomencl._ p. 81; _White,
      P. Z. S._ 1882, p. 615 (Catamarca); _Elliot, Syn. Troch._ p. 36;
      _Gould, Mon. Troch._ ii. pl. 71.

    _Description._--Head, upper surface, and wings greyish olive-brown,
    passing into dull coppery green on the upper tail-coverts; two
    central tail-feathers and outer one bronzy green, the others white,
    narrowly edged externally with brown; throat shining green, bordered
    below by a band of black with bluish reflexions; flanks olive-brown;
    breast and sides of belly white; centre of belly black with
    steel-blue reflexions; under tail-coverts olive: whole length 5·0
    inches, wings 2·7, tail 2·1. _Female_ above like male; beneath
    white, throat densely spotted with brown; flanks brownish.

_Hab._ Chili and Northern Argentina.

White obtained a single specimen of this Humming-bird in September 1880,
at Fuerte de Andalgala, in Catamarca. It is a well-known species in
Chili, where, according to Gould, "it inhabits the sheltered valleys of
the Andes, just below the line of perpetual congelation."

  +Chætocercus burmeisteri+, _Scl. P. Z. S._ 1887, p. 639.

    _Description._--Bill straight, entirely black and as long as the
    head; whole upper part of the body of a dark green metallic colour,
    except the wings, which are black; the small feathers of the throat
    on the under jaw are whitish with a darker spot in the middle; there
    begins on the throat the crimson-red bilateral beard, which is
    composed on both sides of three rows of very small feathers, these
    becoming somewhat larger in the middle of the beard and terminating
    with two ranges of feathers in the exterior half part. Many of these
    feathers are shining metallic green in certain positions. A white
    spot behind the eyes descends from there to the breast, which is
    also whitish, but with a dark spot on every feather, causing a
    greyish appearance in the middle of the breast. The hinder half of
    the breast and the belly are black, but the anal portion is white,
    as also the sides of the body, except the thighs, which are black.
    The inferior feathers behind the anal region are clear yellow-brown,
    but those in the middle have a green metallic spot. The tail is
    composed of eight feathers; the two exterior on each side are more
    than an inch long, very small but of equal size in the whole extent,
    and rounded at the tip, not pointed. The exterior rectrix is
    entirely black; the second has a clear brown stripe on the inside
    border. The third feather of each side is very short, only half an
    inch long and more than eight lines shorter than the exterior; its
    colour is entirely black. The fourth feathers on each side, that
    is in the middle of the tail, are shorter than the third pair and
    partly covered by the coverts: they are of metallic green colour
    like the coverts.

_Hab._ Tucuman.

The only known specimen of this species was procured in the Valle de
Tafi, in the mountains of Tucuman, by Herr Schulz, and is now in the
National Museum of Buenos Ayres. This species is nearly allied to _C.
bombus_, Gould (Mon. Troch. Suppl. p. 45, pl. 32), but differs in the
form of the tail. The figure (Plate XI.) is taken from a watercolour
sketch of this specimen kindly sent to us by Dr. Burmeister.

    _Description._--Head, upper back, wing-coverts, and under surface
    shining bronze-green; lower back and upper tail-coverts shining
    crimson; tail dark brown at base, remaining part fiery orange,
    tipped with black; basal half of outer web of external rectrices
    pale brown; wings purplish brown; under tail-coverts light brown
    with purplish centres; bill and feet black: whole length 6·2 inches,
    wing 2·5, tail 4·1. _Female_: crown and back greenish brown; throat
    and sides of face buffy white, spotted with green; rest of under
    surface whitish, with large spots of green on the flanks; rump and
    upper tail-coverts shining crimson; central rectrices crimson,
    lateral rectrices brownish glossed with crimson; outer web of
    external rectrix white; bill and feet black.

_Hab._ Bolivia and North-western Argentina.

Dr. Burmeister tells us that the Sappho Humming-bird is not uncommon in
Mendoza, Catamarca, and Tucuman, but keeps to the mountains, and does
not descend on to the plains. In the neighbourhood of Mendoza it
specially affects the flowers of _Loranthus cuneifolius_; at Tucuman
Dr. Burmeister found it also on the orange-blossoms.

Durnford obtained specimens of this species at Tucuman and Salta in the
month of June.

White (P. Z. S. 1882, p. 615) gives us the following notes on its

"I have met with these Humming-birds scattered, although somewhat
sparsely, over the upper provinces of the Republic, feeding principally
upon _Nicotiana glauca_, the Quichua name for which is 'palan-palan.'
They follow it southwards as it flowers, even as far as Cordoba; but
their true habitat is the Andean region. In Quichua, Humming-birds
generally are called 'Tuminicos.' When these birds are poised in front
of a flower with wings and tail expanded in the full sunshine, they
offer the most brilliant feathery picture imaginable; and as they dart
off their flight is so speedy that the eye cannot follow them."

      +Petasophora crispa+, _Burm. La-Plata Reise_, ii. p. 447

    _Description._--Head, upper surface, wing-coverts, flanks, and
    abdomen dark yellowish green; ear-coverts rich violet-blue; wings
    purplish brown; tail dark bluish green, crossed near the tip by a
    broad chalybeate band, beyond which the tips are of a lighter bluish
    green; throat and upper part of the breast luminous green; across
    the breast a gorget of shining bluish green; vent and under
    tail-coverts pure white; bill black; feet blackish brown: whole
    length 3·8 inches, wings 2·8, tail 1·7. _Female_ similar, but not
    so bright.

_Hab._ S.E. Brazil.

Dr. Burmeister informs us that he met with this Humming-bird in
multitudes in the month of September among the orange-blossoms in the
Quintas of Tucuman. It is a well-known species in South-east Brazil, but
we know of no other record of its occurrence so far south as Tucuman.

234. PATAGONA GIGAS (Vieill.).


  +Patagona gigas+, _Scl. et Salv. Nomencl._ p. 89; _White, P. Z. S._
      1882, p. 615 (Catamarca); _Elliot, Syn. Troch._ p. 67; _Gould,
      Mon. Troch._ iv. pl. 232.

    _Description._--Head and upper surface pale brown, glossed with
    green; wings and tail darker and more green; basal portion of the
    shafts of the lateral rectrices white; patch on the rump white;
    upper tail-coverts edged with white; breast mottled brown and
    buff; throat and abdomen rusty red; under tail-coverts white, with
    brownish centre spots; bill blackish brown; feet brown: whole length
    7·0 inches, wing 4·9, tail 3·4. _Female_ similar but smaller.

_Hab._ Andes of Ecuador, Bolivia, and Peru, Chili, Patagonia, and
Northern Argentina.

White seems to be the only observer who has met with this Humming-bird
within the limits of the Argentine Republic. He obtained a pair at
Andalgala, in Catamarca, in September 1880, and wrote the following
notes on the habits of the species:--

"This magnificent bird, which the natives say they have never seen
before at Andalgala, was shot on the 'palan-palan,' the usual plant that
it frequents at this season. It appeared here just after a two days'
severe snow-storm, so that in all probability it had been driven down
hither by it.

"It is exceedingly powerful on the wing, and flutters in front of a
flower, sipping the nectar, exactly as the smaller species of this
family. They have a most peculiar, zig-zag, jerky flight; which, when
making a long detour for any particular spot, becomes undulating.

"They are without doubt partially insect-eaters, as I have not only
observed their crops full of flies and small beetles, but have also seen
them pursue and catch them in the air, with the motions of a Flycatcher.

"They perch on some bare branch of a plant, which they entirely
appropriate, driving off every other bird that dares to approach, and
every now and then visit all its flowers to sip the sweets. The large
humble-bees, however, cause them some trouble, as they likewise are
addicted to sipping nectar; these the _P. gigas_ attacks with all its
force, and by fluttering its wings, rushing at, pushing and pecking
them, succeeds in ridding the spot of their presence.

"The note of this bird is similar to the chirp of a young Sparrow, but
much stronger.

"These birds, like animals generally in the Argentine Republic,
take no notice of a person mounted, but instantly disappear when a
foot-passenger approaches; so that as I was on muleback I was enabled
to ride close up to and observe them.

"The seat of _P. gigas_ is so firm and close to the branch, that its
tiny feet are invisible; the breast is puffed out, and its head in
continued motion from one side to the other with a jerky movement. When
disturbed it darts off around with a rough jerky flight for a minute or
so, and then endeavours to return, but, if still interfered with, seeks
a dry twig at the top of some neighbouring tree on which to alight. Its
poise when suspended, sipping at the flowers, is heavy and laboured, and
the motion of its large wings, although rapid, is perceptible to the
eye; and it never remains more than half a minute in this position, when
it retires to a branch to rest for at least five minutes, perching, with
its head towards the sun and its beak slightly elevated."

    _Description._--Crown of head luminous metallic green, changing in
    some lights to aquamarine, in others to bluish green, and in others
    to golden green; all the upper surface and wing-coverts golden
    green, the golden hue predominating on the lower part of the back;
    wings purplish brown; tail purplish black, glossed with dark green;
    behind the eye a spot of white, and on the cheeks a streak of grey;
    centre of throat rich metallic purplish crimson, on each side of
    which is a series of elongated feathers of a rich deep metallic
    blue; under surface deep green, passing into rich blue on the middle
    of the body; tuft on each side and vent white; under tail-coverts
    green, fringed with white; bill black; feet blackish brown: whole
    length 5·2 inches, wing 2·3, tail 1·7. _Female_: the whole of the
    upper surface golden bronze, inclining to grey on the crown; tail
    green, deepening into black towards the extremity, and a spot of
    white at the tip of the three outer feathers of each side; wings
    purplish brown; under surface grey, fading into white on the throat
    and middle of belly.

_Hab._ S. Brazil, Paraguay, and Argentina.

Of the three Humming-birds which visit the vicinity of Buenos Ayres in
the summer months, Mr. Durnford tells us this is the rarest. It
is occasionally seen in the riverain wood, and like the other two
(_Hylocharis sapphirina_ and _Chlorostilbon splendidus_) may generally
be found hovering over the flowers of the Ceiba-tree--a species of

Further to the north this species would seem to be more abundant.
Dr. Burmeister met with it near Tucuman and Paraná, and at one time
described the young birds obtained in the latter locality as of a
distinct species (_Campylopterus inornatus_), an error which he
subsequently corrected (_cf._ P. Z. S. 1864, p. 466). White procured
it in the city of Catamarca in August 1880.

Mr. Barrows has published the following interesting account of his
observations on this species in Entrerios (Auk, 1882, p. 21):--

"Early in September, at Concepcion, when the orange-trees are just
whitening with blossoms, these magnificent Humming-birds arrive from
the north, and may occasionally be seen about the orange-trees in any
garden, as well as about blossoming trees elsewhere. The males seemed
for some reason to be much less abundant than the females, hardly more
than a dozen being seen in an entire season. They probably nest in
November and December, and leave for the north again in February or
March. A nearly finished nest, found November 17, was very similar to
that of our own Ruby-throat (_Trochilus colubris_) but larger, and was
built in the compound fork of a large limb at a height of over 25 feet
from the ground. It was deserted soon after, perhaps as a result of
my examination. Ten days later another nest was found saddled on the
topmost horizontal limb of a dead and moss-grown stub; only about seven
feet from the ground, and exposed to the full force of the sun.
This nest contained two eggs nearly ready to hatch. Both nests were
beautifully covered with lichens, and the last was lined with the finest
of vegetable down. The female made several angry rushes at me before
the nest was touched, but as soon as she saw that it was discovered
became so shy that it was difficult to secure her. The male was not seen
at all. I once saw a bird of this species attack and put to rout a wild
dove which passed near it while feeding, and though the dove made every
effort to escape, the Hummer not only kept up with it easily, but darted
above and below it as well, and finally both went out of sight in the
distance together."

White obtained examples of this species at Fuerte de Andalgala, in
Catamarca, in September 1880. They were feeding on the flowers of
the "Idiondilla," which is one of the "Humming-bird-plants" of that
district. "They are very swift and wild in their movements," he tells
us, and "make a very loud hum," louder in fact than any other species
with which he was acquainted.

with _Calliperidia furcifera_ and _Petasophora serrirostris_; but we
have no other authority for its occurrence within the limits of the
Argentine Republic.

Hans v. Berlepsch has lately shown that Azara described this species
under the designation "_Picaflor cola de topacio_," and that it must
consequently bear the name _ruficollis_ of Vieillot, instead of
_chrysura_ of Lesson, by which it is more commonly known. It visits the
more northern portion of the Argentine Republic, and was obtained in the
vicinity of Buenos Ayres by Hudson at Conchitas, and by Durnford at
Punta Lara. The British Museum contains specimens from both these

_Hab._ Southern Brazil, Paraguay, and Northern Argentina.

The Red-throated Humming-bird is abundant in the woods along the Plata
river, and ranges, I believe, fifty or sixty miles south of Buenos Ayres
city. Outside of the littoral woods it is very rarely met with. The only
nest I have found was in my own garden, and was placed on a horizontal
branch. The female continued sitting on the nest, which contained two
eggs, even when I placed my hand almost touching it; the male bird in
the mean time exhibiting the greatest anxiety, and hovering so near as
almost to brush my face with its wings.

The Glittering Humming-bird appears in the vicinity of Buenos Ayres in
September, and later in the spring is found everywhere on the pampas
where there are plantations, but it is never seen on the treeless
plains. Its sudden appearance in considerable numbers in plantations on
the pampas, where there are flowers to which it is partial, like those
of the acacia-tree, and its just as sudden departure when the flowers
have fallen, have led me to conclude that its migration extends much
further south, probably into mid-Patagonia. Like most Humming-birds it
is an exquisitely beautiful little creature, in its glittering green
mantle; and in its aerial life and swift motions a miracle of energy.
To those who have seen the Humming-bird in a state of nature all
descriptions of its appearance and movements must seem idle. In the
life-habits of the Trochilidæ there is a singular monotony; and the
Glittering Humming-bird differs little in its customs from other species
that have been described. It is extremely pugnacious; the males meet to
fight in the air, and rapidly ascend, revolving round each other, until
when at a considerable height they suddenly separate and dart off in
opposite directions. Occasionally two or three are seen flashing by,
pursuing each other, with such velocity that even the Swift's flight,
which is said to cover four hundred miles an hour, seems slow in
comparison. This species also possesses the habit of darting towards a
person and hovering bee-like for some time close to his face. It also
flies frequently into a house, at window or door, but does not, like
birds of other kinds, become confused on such occasions, and is much
too lively to allow its retreat to be cut off. It feeds a great deal on
minute spiders, and is fond of exploring the surfaces of mud and brick
walls, where it is seen deftly inserting its slender crimson bill into
the small spider-holes in search of prey. The nest, like that of most
humming-birds, is a small, beautifully-made structure, composed of a
variety of materials held closely together with spiders' webs, and
is placed on a branch, or in a fork, or else suspended from slender
dropping vines or twigs. Sometimes the nest is suspended to the thatch
overhanging the eaves of a cottage, for except where persecuted the bird
is quite fearless of man's presence. The eggs are two, and white.

Besides the little creaking chirp uttered at short intervals while
flying or hovering, this species has a set song, composed of five or six
monotonous squeaking notes, uttered in rapid succession when the bird is

Dr. Burmeister met with this Humming-bird at Mendoza, Paraná, and
Tucuman, and says it is the commonest species in La Plata, and easily
recognizable by its red bill.

Mr. Durnford also pronounces this species to be the commonest
Humming-bird in the province of Buenos Ayres, and "abundant in the
summer." It is not usual to meet with them in the winter; but Durnford
saw a single specimen in a sheltered garden in the beginning of June.
This Humming-bird feeds principally, he tells us, on the flowers of the
Ceiba-tree, but not exclusively on honey, for the stomach of a specimen
examined contained fragments of minute Coleoptera.

During his last journey Durnford obtained examples of this species near
Salta; and White found it very abundant and breeding near Catamarca in
the month of September.

According to Mr. Barrows the Glittering Humming-bird is also very common
in Entrerios; he writes as follows:--"Very abundant at Concepcion in
summer, arriving from the north early in September and departing again
in April. Though found everywhere among flowers, they are particularly
partial to open ground, flowery fields, gardens, &c., and in October it
was not uncommon to have six or eight in sight at once."


The cosmopolitan family of Swifts, as far as is yet known, represented
by one species only in the Argentine Republic. This is a fine large form
of wide distribution, which extends over most of Southern and Central



  +Hemiprocne zonaris+, _Scl. et Salv. Nomencl._ p. 95. +Acanthylis
      collaris+, _Burm. La-Plata Reise_, ii. p. 449 (Mendoza).

    _Description._--Black, glossed with bronzy; a white collar round the
    neck, rather broader in front; tail spiny, slightly forked: whole
    length 8·5 inches, wing 7·5, tail 2·8. _Female_ similar.

_Hab._ Central and South America down to Argentina.

Dr. Burmeister observed specimens of this fine large Spine-tailed Swift
near the Sierra of Mendoza in December and the following month.


Nearly fifty different species of the singular nocturnal birds commonly
known as "Goatsuckers" are found in the Neotropical Region. They are
most numerous within the tropics, where insect-life is more abundant,
but also occur more sparingly in temperate latitudes. Six of them have
been recorded as having been met with within the limits assigned to this

The Goatsuckers generally take their insect-prey on the wing late in
the evening; but many of them often alight on the ground, and usually
nest there or in hollow trees.

242. PODAGER NACUNDA (Vieill.).


  +Podager nacunda+, _Scl. et Salv. Nomencl._ p. 95; _iid. P. Z. S._
      1868, p. 142 (Buenos Ayres); _Burm. La-Plata Reise_, ii. p. 449
      (Paraná); _Barrows, Auk_, 1884, p. 24 (Entrerios, Bahia Blanca).

    _Description._--Above brown with dense black vermiculations and
    occasional blotches; wings black, with a broad white cross bar
    across the base of the primaries; secondaries and coverts like the
    back; tail above like the back, beneath grey with blackish cross
    bands; four outer tail-feathers broadly tipped with white: beneath,
    breast brown variegated with black, as above; chin fulvous; band
    across the throat and whole belly and crissum white; bill black;
    feet pale brown: whole length 11·0 inches, wing 9·5, tail 4·9.
    _Female_ similar, but without the white ends to the tail-feathers.

_Hab._ South America.

The specific name of this Goatsucker is from the Guaraní word _Ñacundá_,
which Azara tells us is the Indian nickname for any person with a very
large mouth. In the Argentine country it has several names, being called
_Dormilon_ (Sleepy-head) or _Duerme-duerme_ (Sleep-sleep), also _Gallina
ciega_ (blind hen). It is a large handsome bird, and differs from
its congeners in being gregarious, and in never perching on trees or
entering woods. It is an inhabitant of the open pampas. In Buenos Ayres,
and also in Paraguay, according to Azara, it is a summer visitor,
arriving at the end of September and leaving at the end of February. In
the love season the male is sometimes heard uttering a song or call,
with notes of a hollow mysterious character; at other times they are
absolutely silent, except when disturbed in the daytime, and then each
bird when taking flight emits the syllable _kuf_ in a hollow voice. When
flushed the bird rushes away with a wild zigzag flight, close to the
ground, then suddenly drops like a stone, disappearing at the same
moment from sight as effectively as if the earth had swallowed it up,
so perfect is the protective resemblance in the colouring of the upper
plumage to the ground. In the evening they begin to fly about earlier
than most _Caprimulgi_, hawking after insects like swallows, skimming
over the surface of the ground and water with a swift, irregular flight;
possibly the habit of sitting in open places exposed to the full glare
of the sun has made them somewhat less nocturnal than other species that
seek the shelter of thick woods or herbage during the hours of light.

The Nacunda breeds in October, and makes no nest, but lays two eggs on a
scraped place on the open plain. Mr. Dalgleish says of the eggs:--"They
are oval-shaped, and resemble much in appearance those of the Nightjar,
except that the markings, which are similar in character to those of the
latter, are of a reddish-brown or port-wine colour."

After the breeding-season they are sometimes found in flocks of forty or
fifty individuals, and will spend months on the same spot, returning to
it in equal numbers every year. One summer a flock of about two hundred
individuals frequented a meadow near my house, and one day I observed
them rise up very early in the evening and begin soaring about like a
troop of swallows preparing to migrate. I watched them for upwards of an
hour; but they did not scatter as on previous evenings to seek for food,
and after a while they began to rise higher and higher, still keeping
close together, until they disappeared from sight. Next morning I found
that they had gone.

In Entrerios, Mr. Barrows tells us, this Goatsucker is an abundant
summer resident, arriving early in September, and departing again in
April. It is strictly crepuscular or nocturnal, never voluntarily taking
wing by daylight. In November it lays a pair of spotted eggs in a hollow
scooped in the soil of the open plain. These in shape and markings
resemble eggs of the Nighthawk (_Chordeiles virginianus_) somewhat, but
are of course much larger, and have a distinct reddish tinge. We found
the birds not uncommon near Bahia Blanca, February 17, 1881, but
elsewhere on the Pampas we did not observe them.

      Auk_, 1884, p. 24 (Entrerios); _Berlepsch, J. f. O._ 1887, p. 120

    _Description._--Above black, varied and mottled with brown; wings
    black, with a broad white bar across the bases of the five outer
    primaries; tail black, with brown cross bands and a broad white
    subapical bar: beneath white, with dense blackish cross bands;
    breast blacker; broad throat-band white; bill black; feet pale
    brown: whole length 8·5 inches, wing 7·8, tail 4·0. _Female_
    similar, but throat-band tawny and no white band on the tail.

_Hab._ North and South America.

The well-known "Whip-poor-Will" of the U. S. appears to extend its
winter-migration into Northern Argentina. Mr. Barrows has recorded the
capture of two specimens of this species at Concepcion in Entrerios in
January 1880 and December of the same year. Its occurrence in Paraguay
is also known to us, and Natterer obtained examples of it in S.E.

    _Description._--Above rufous mottled with blackish, crown black;
    tips of wing-coverts spotted with white; beneath fulvous with
    irregular black cross bands; primaries black, with white bars across
    the second, third, and fourth about half-way down; tail like the
    back, but tips of outer rectrices white: whole length 7·5 inches,
    wing 5·3, tail 4·0. _Female_ similar, but without the white spots on
    the wings and tail.

_Hab._ Brazil and Argentina.

Resident, according to Mr. Durnford, in the province of Buenos Ayres,
"but probably, from its shy and retiring disposition, considered rarer
than it really is. Like our Nightjar (_Caprimulgus europæus_) it
frequents open spots in sheltered coppices on banks under a sheltering
hedge of thorns, and may generally be found in the same place from day
to day, coming out about dusk in quest of moths and other insects."

Mr. Barrows tells us that this species is not uncommon in Entrerios in
summer time, and "doubtless breeds." At dusk he frequently saw it
near the margins of the woods and thickets, where it makes only short
flights, soon settling on the ground.

Gould's original description of this species was based on a specimen
obtained by Darwin near Santa Fé on the Paraná, which is now in the
British Museum.

      longirostris+, _Burm. La-Plata Reise_, ii. p. 450 (Mendoza).

    _Description._--Above greyish brown variegated with black, crown
    black; light rufous collar at the back of the neck; wing-coverts
    with large light brown spots; primaries black, with a broad white
    bar across the five outer ones; tail black; lateral rectrices with a
    white bar near the base, and very broad white tips: beneath fulvous,
    with narrow blackish cross bands; throat-band white; crissum pale
    fulvous: whole length 10·0 inches, wing 6·0, tail 5·0. _Female_
    similar, but the white on the throat, wings, and tail replaced by
    fulvous and less extended.

_Hab._ Chili, Patagonia, and Argentina.

A single skin of this species was obtained at Conchitas by Hudson.
Durnford also found it rather rare in Chupat and its vicinity, though
resident and breeding in that district. "When flushed it never flies
very far, but seeks the shelter of a small bush, squatting flat on the
ground, and from its peculiar zigzag mode of flight it is difficult for
the eye to follow it."

    _Description._--Above brown varied with black; a light rufous collar
    on the back of the neck; wing-coverts with numerous rounded white or
    fulvous spots; wings black, crossed beneath by pale rufous bands;
    outer primary edged with white: beneath paler, with a pale fulvous
    throat-collar; tail with the outer rectrix twice as long as the
    middle pair, black, edged with white; the next three pairs similar,
    but gradually diminishing in length; the middle pair like the back,
    and rather longer than the second pair: whole length 20·0 inches,
    wing 7·2, tail 15·5. _Female_ similar, but tail short, black banded
    with fulvous, and without any white.

_Hab._ Paraguay and Argentina.

This remarkable Goatsucker was often observed by Durnford in the
province of Buenos Ayres in spring and autumn. It lives on the ground,
generally in damp situations, and where the grass is long and thick
enough to afford some slight cover, and is generally observed in parties
of four or five individuals. Its flight is noiseless, and performed by
jerky erratic movements. In Entrerios Mr. Barrows tells us this species
is a "rather common summer resident, arriving in August and leaving in
May. While hunting capybaras and armadillos by moonlight he frequently
had good opportunities for watching its movements. Its flight is
nearly as irregular and as noiseless as that of a butterfly, while
its beautiful tail is opened and shut in the same manner as with the
Scissor-tailed Flycatcher. Alighting frequently on the ground or on
stones or roots, it keeps up a continual but very soft clucking, which
is the only note uttered. It was most often seen in open grassy or sandy
spots in the woods, especially along the margins of the streams. By day
it sits close on the ground, and if disturbed only flies a few yards,
though it evidently sees well." Of its nesting-habits and eggs Mr.
Barrows did not obtain any information.

The figure (Plate XII.) is taken from a specimen in Sclater's
collection, which was obtained at Gualeguaychú in Entrerios by Mr. Lee.

    _Description._--Greyish brown, irregularly dashed and spotted with
    black; long superciliaries and faint nuchal collar pale fawn-colour;
    wing-coverts and secondaries like the back, but with pale
    fawn-coloured spots; primaries black, with the basal portion reddish
    fawn-colour and tips white, the first six nearly equal in length,
    and curved inwards; tail fawn-colour, irregularly barred with
    blackish, two centre feathers like the back: beneath, throat and
    breast blackish brown, with slight fawn-coloured shaft-spots;
    abdomen pale fawn-colour, with irregular blackish cross bands; tarsi
    long, naked: whole length 7·0 inches, wing 5·2, tail 3·5. _Female_
    similar, but wings banded with rufous, and without the white tips.

_Hab._ South Brazil and Argentina.

Mr. Durnford obtained a single female of this rare and anomalous
Caprimulgine form on the 31st of March, 1877, near Quilmes in the
province of Buenos Ayres. It was flushed from a clump of thistles, and
its stomach was full of insect-remains.

Order III. PICI.


The Woodpeckers are distributed all over the world except Australia and
the adjacent islands (up to Flores and Celebes) and Madagascar. They
are very abundant in the Neotropical and Oriental Regions, where great
forests predominate. From South and Central America about 120 species,
mostly belonging to peculiar genera, have been recorded. In Argentina,
as might have been expected from the vast extent of the pampas
districts, Woodpeckers are not so plentiful as in the densely wooded
countries of Amazonia and Colombia. But four Woodpeckers are met with in
the riverain woods of Buenos Ayres, and a fifth, a curiously modified
form, is peculiar to the Pampas, while eight others are known with more
or less certainty from the northern provinces of the Republic.

      _Barrows, Auk_, 1884, p. 25 (Entrerios).

    _Description._--Above and beneath black; crested head and neck
    scarlet, ear-coverts black, with a white line below; upper back and
    interscapulium pale tawny white; bend of wing cinnamomeous; inner
    webs of primaries pale chestnut; bill white, feet black: whole
    length 12·0 inches, wing 7·4, tail 4·2. _Female_ similar, but head
    black, except the sides of the back of the head and the under
    portion of the crest, which are scarlet.

_Hab._ Bolivia and Northern Argentina.

Durnford found this fine Woodpecker "resident and common" to the north
of Buenos Ayres, and on the banks of the Paraná. It is likewise met with
in the more northern provinces of the Republic. White obtained specimens
in Catamarca and Salta, and Durnford, during his last expedition, in the
latter locality. Mr. Barrows speaks of its occurrence in Entrerios as

"A part of the last week in April 1880 was spent in a considerable tract
of forest bordering a stream known as the 'Arroyo Gualeguaychú' at a
point about twenty miles west of Concepcion. The wood borders the stream
to a depth of a mile or more on each side and stretches up and down
stream indefinitely. It had suffered comparatively little from the axe
of the charcoal-burner, and many birds, not elsewhere seen, were met
with here. Among these was the present beautiful Woodpecker, of which,
however, only a single pair was observed, and the male alone taken. It
is said to occur sparingly in all the large forests."



  +Phloeotomus schulzi+, _Cab. Journ. f. Orn._ 1883, p. 102. +Dryocopus
      atriventris+, _Burm. La-Plata Reise_, ii. p. 444 (?).

Under this title Dr. Cabanis has shortly described a Woodpecker procured
in Central Argentina by Herr Schulz. It is a diminutive form of _C.
pileatus_ of North America; and differs from that species in colour only
in the following points:--The red crest is comparatively more developed
and more pointed; the general colour is more intensely black; the white
markings of _C. pileatus_ are present in _C. schulzi_, but the extent of
the white on the underside of the wings and on the carpal joint is much
less in the latter species. No dimensions are given.

Dr. Cabanis is of opinion that the bird from Mendoza described by Dr.
Burmeister as the young of _C. boiæi_ is referable to this new species.

    front beneath the eye and down the neck white; malar patch scarlet:
    beneath, throat white, with black striations; breast black; belly
    white, transversely barred with black; under surface of wings white;
    bill plumbeous; feet black: whole length 13·0 inches, wing 7·5, tail
    5·0. _Female_ similar, but anterior half of head black, and no
    scarlet malar patch.

_Hab._ Brazil.

White states that he "observed" a few specimens of this Brazilian
species in the dense forests of Misiones; but its occurrence so far
south requires confirmation. A more likely species of this genus to
occur there would be _D. lineatus_, which has been found in Paraguay
(_cf._ Berlepsch, J. f. O. 1887, p. 20).

251. PICUS MIXTUS, Bodd.


  +Picus mixtus+, _Scl. et Salv. Nomencl._ p. 99; _Durnford, Ibis_,
      1878, p. 62 (Buenos Ayres); _White, P. Z. S._ 1882, p. 617
      (Catamarca); _Barrows, Auk_, 1884, p. 25 (Entrerios); _Withington,
      Ibis_, 1888, p. 467 (Lomas de Zamora).

    _Description._--Above black, with regular white cross bars; head
    black, with narrow yellowish shaft-spots; a large patch behind the
    ear on each side of the neck white; feathers of the nape slightly
    pointed with rosy red: beneath white, with longitudinal black
    stripes; under surface of wings white, with black cross bars: whole
    length 6·0 inches, wing 3·5, tail 2·2. _Female_ similar, but head
    uniform black, and no red on the nape.

_Hab._ South Brazil and Argentina.

In the district of Buenos Ayres this little Woodpecker, the smallest
of the Argentine species of the family, is usually called _Come-palo_
(Wood-eater) in the vernacular. It has all the habits characteristic of
the true Woodpeckers, inhabiting the woods and perching vertically on
the trees, where it is heard vigorously striking the bark to dislodge
the lurking insects with its sharp beak. When disturbed it flits away
with a shrill querulous cry, passing to the nearest tree with a rapid
undulating flight, and conceals itself by running round the bole to the
opposite side. It excavates a straight hole in a rotten or decaying
branch to breed in, and a common species of _Synallaxis_ (_Leptasthenura
ægithaloides_) frequently makes use of its forsaken breeding-holes. The
entire plumage in both sexes is very dark, nearly black, densely and
evenly marked with oblong white spots. The loose feathers of the crown
are black tipped with scarlet, but in the female the one spot of bright
colour is scarcely if at all perceptible.

White met with this Woodpecker near Cordova and in Catamarca, and Mr.
Barrows in Entrerios, where, however, though resident, it does not
appear to be common.

      cactorum+, _Burm. La-Plata Reise_, ii. p. 445 (Catamarca).

    _Description._--Above black; large blotch on the front and another
    on the nape dull white; small coronal spot scarlet; wings and tail
    black, with white cross bands; rump white, spotted with black:
    beneath buffy white, throat strongly tinged with orange; bill and
    feet black: whole length 6·8 inches, wing 4·1, tail 2·3. _Female_
    similar, but without the red spot on the crown.

_Hab._ Bolivia and Northern Argentina.

Prof. Burmeister met with three specimens of this Woodpecker at
Capellán, south-west of Catamarca. White obtained examples of both sexes
in Catamarca, and found it tolerably abundant in that province. "Three
or four are usually observed together on a large cactus, but on being
disturbed either take to another cactus or to the lofty branches of

In Entrerios Mr. Barrows tells us this species is more common than _P.
mixtus_, but abundant only on the Gualeguaychú, about twenty miles west
of Concepcion.



  +Chloronerpes affinis+, _Scl. et Salv. Nomencl._ p. 99; _White, P. Z.
      S._ 1882, p. 617 (Salta).

    _Description._--Above dull olive-green, with fine yellowish
    shaft-spots; wings and tail black, spotted with white; head black,
    bordered behind by a yellow nuchal collar, front of head with white
    shaft-spots, hinder half with scarlet ends to the feathers: beneath
    greyish white, with narrow black cross bands; under surface of wings
    white, barred with black: whole length 6·5 inches, wing 3·7, tail
    2·4. _Female_ similar, but without any red on the nape.

_Hab._ Brazil.

White identified a pair of birds obtained at Campo Santo, in Salta, as
belonging to this species, but his determination requires confirmation,
as there are several forms of this genus nearly alike which require
accurate discrimination.



  +Chloronerpes (Campias) frontalis+, _Cab. Journ. f. Orn._ 1883, p.

    _Description._--Like _C. maculifrons_ (Spix), but larger; red of
    head darker and broader, and without any golden-yellow border;
    beneath darker and more thickly cross-banded, with the bright bands

_Hab._ Tucuman.

This little-known species is one of Herr Fritz Schulz's discoveries in
the mountain-forests of Tucuman.



  +Chloronerpes aurulentus+, _Scl. et Salv. Nomencl._ p. 99; _White, P.
      Z. S._ 1882, p. 617 (Misiones).

    _Description._--Above olive-green, crown and malar stripe scarlet;
    sides of head slaty, with a yellowish line above and beneath; wings
    black, with transverse bars of rusty red; tail black: beneath
    greyish white, regularly barred across with black, throat yellow:
    whole length 8·0 inches, wing 4·8, tail 2·2. _Female_ similar, but
    only the nape scarlet, rest of cap like the back.

_Hab._ Brazil.

The occurrence of this Woodpecker in Argentina also rests upon White's
authority. But as it is found in Paraguay (_cf._ Berlepsch, J. f. O.
1887, p. 120), it is very likely to extend into Misiones. White states
that it is common in San Javier, and usually "seen singly in dead high



  +Chloronerpes tucumanus+, _Cab. Journ. f. Orn._ 1883, p. 103.

    distinguishable by its rather larger size and darker under surface,
    in which the yellowish hue is wanting.

_Hab._ Tucuman.

This is another discovery of Herr Fritz Schulz in Tucuman, which has
been shortly described by Dr. Cabanis.

    white, bordered beneath by black, which carries a scarlet malar
    stripe: beneath white, on the neck yellowish, thickly covered with
    round black spots; throat white, striped with black; under surface
    of wings white, tinged with yellow; tail black, lateral rectrices
    slightly barred with yellowish; bill and feet black: whole length
    10·5 inches, wing 5·8, tail 4·0. _Female_ similar, but without the
    scarlet malar patch.

_Hab._ Paraguay and Argentina.

This Woodpecker ranges as far south as the vicinity of Buenos Ayres, and
is not uncommon there in the few localities which possess wild forests.
It is the handsomest of our Woodpeckers, having brighter tints than its
congener of the plains, _Colaptes agricola_. Like that bird, though
not to the same extent, it has diverged from the typical Picidæ in its
habits, alighting sometimes on the ground to feed, and also frequently
perching crosswise on branches of trees. It has a powerful, clear,
abrupt, and oft-repeated note, and a rapid undulating flight.

The following interesting account of its breeding-habits appears in one
of Mr. Gibson's papers:--"The excavation for the nest is begun as early
as September; but the eggs are only laid during the first half of
October. The hole is generally commenced where some branch has decayed
away; but care is taken that the remainder of the tree is sound. It
opens at a height of from six to nine feet from the ground, and is
excavated to a depth of nearly a foot. Occasionally it is sufficiently
wide to admit of one's hand, but such is not always the case. No
preparation is made for the eggs beyond the usual lining of some chips
of wood.

"The pair which frequented the garden excavated a hole in a
paradise-tree, and bred there for two consecutive years. The tree
stood near one of the walks, and on any one passing the sitting bird
immediately showed its head at the aperture, like a jack-in-the-box, and
then flew away. Last year this pair actually bred in one of the posts of
the horse-corral, notwithstanding the noise and bustle incident to such
a locality. While waiting there, at sunrise, for the herd of horses
to be shut in I used often to knock at the post, in order to make the
Woodpecker leave its nest, but the bird seemed indifferent to such a
mild attack, and would even sit still while a hundred horses and mares
rushed about the corral or hurled themselves against the sides of it.
In another case I had worked with hammer and chisel for half-an-hour,
cutting a hole on a level with the bottom of a nest, when the female
first demonstrated her presence by flying out almost into my face. This
last nest contained four (considerably incubated) eggs, which I took.
Happening to pass the spot a fortnight after, I inspected the hole and
was surprised to find that it had been deepened and other five eggs
laid, while the entrance I had cut was the one now used by the birds.
The nest was again resorted to the following year and a brood hatched
out, but since then a pair of Wrens have occupied the place to the
exclusion of the rightful owners."

The eggs are white, four or five in number, pear-shaped, and with
polished shells.

White obtained specimens of this Woodpecker in Catamarca, and Mr.
Barrows found it resident in Entrerios. The latter tells us it is
"abundant in the woods everywhere, and conspicuous for its activity,
bright colours, and large size."

White speaks of this species as follows:--"These noisy birds, abundant
in various parts of Misiones as well as in the rest of the north of
the Republic, go about in flocks of eight or ten, and settle on the
same tree, which they proceed to ascend very comically in a spiral or
corkscrew fashion, each head touching the preceding tail. They are not
seen in dense forests, but only out in the open, on some old, usually
dead, tree, and I think I observed them as far south as the sierras of



  +Colaptes longirostris+, _Cabanis, Journ. f. Orn._ 1883, p. 97.

    much longer.

_Hab._ Tucuman.

This is a southern form of the Brazilian _C. rupicola_, which has been
recently described by Dr. Cabanis. Herr Schulz obtained a single male
example of this species in Tucuman. Like _C. rupicola_ it has red
moustaches, but no red nape-band, whereas the more northern _C. pura_
of Peru shows a red nape-band in both sexes.

_Hab._ Argentina and Patagonia.

The species commonly called _Carpintero_ in the Argentine country,
and ranging south to Patagonia, is one of a group of the Picidæ of
South America which diverge considerably in habits from the typical
Woodpeckers. On trees they usually perch horizontally and crosswise,
like ordinary birds, and only occasionally cling vertically to trunks of
trees, using the tail as a support. They also seek their food more on
the ground than on trees, in some cases not at all on trees, and they
also breed oftener in holes in banks or cliffs than in the trunks of
trees. As Darwin remarks in 'The Origin of Species,' in his chapter
on Instinct, these birds have, to some slight extent, been modified
structurally in accordance with their less arboreal habits, the beak
being weaker, the rectrices less stiff, and the legs longer than in
other Woodpeckers. In South Brazil and Bolivia the _Colaptes campestris_
represents this group, in Chili _C. pitius_, and in the Argentine
country _C. agricola_.

Azara's description, under the heading _El Campestre_, probably refers
to the Brazilian species, but agrees so well in every particular with
the pampas Woodpecker that I cannot do better than to quote it in full.

"Though this name (_Campestre_) seems inappropriate for any Woodpecker,
no other better describes the present species, since it never enters
forests, nor climbs on trunks to seek for insects under the bark, but
finds its aliment on the open plain, running with ease on the ground,
for its legs are longer than in the others. There it forcibly strikes
its beak into the matted turf, where worms or insects lie concealed,
and when the ant-hills are moist it breaks into them to feed on the ants
or their larvæ. It also perches on trees, large or small, on the trunks
or branches, whether horizontal or upright, sometimes in a clinging
position and sometimes crosswise in the manner common to birds. Its
voice is powerful, and its cry uttered frequently both when flying
and perching. It goes with its mate or family, and is the most common
species in all these countries. It lays two to four eggs, with white and
highly polished shells, and breeds in holes which it excavates in old
walls of mud or of unbaked brick, also in the banks of streams; and the
eggs are laid on the bare floor without any lining."

In Patagonia, where I have found this bird breeding in the cliffs of the
Rio Negro, its habits are precisely as Azara says; but on the pampas of
Buenos Ayres, where the conditions are different, there being no cliffs
or old mud-walls suitable for breeding-places, the bird resorts to the
big solitary ombú tree (_Pircunia dioica_), which has a very soft wood,
and excavates a hole 7 to 9 inches deep, inclining upwards near the end,
and terminating in a round chamber.

This reversion to an ancestral habit, which (considering the modified
structure of the bird) must have been lost at a very remote period in
its history, is exceedingly curious. Formerly this Woodpecker was quite
common on the pampas. I remember that when I was a small boy quite a
colony lived in the ombú trees growing about my home; now it is nearly
extinct, and one may spend years on the plains without meeting with a
single example.

Mr. Barrows speaks as follows of this species:--"Abundant and breeding
at all points visited. At Concepcion, where it is resident, it is by
far the commonest Woodpecker. The ordinary note very much resembles
the reiterated alarm-note of the Greater Yellow-legs (_Totanus
melanoleucus_), but so loud as to be almost painful when close at hand,
and easily heard a mile or more away. They spend much time on the
ground, and I often found the bills of those shot quite muddy. They are
very tough and hard to kill, and a wounded one shows about as many sharp
points as a Hawk. A nest found near Concepcion, November 6, 1880, was in
the hollow trunk of a tree, the entrance being through an enlarged crack
at a height of some three feet from the ground. The five white eggs were
laid on the rubbish at the bottom of the cavity, perhaps a foot above
the ground. In the treeless region about the Sierra de la Ventana we saw
this bird about holes on the banks of the streams, where it doubtless
had nests."



The Kingfishers, which form the subject of an excellent illustrated
Monograph by Mr. Sharpe[1], are but feebly represented in the New World.
Out of the many varied generic forms which make up the family, only a
single genus, with about eight species, is met with in the whole of the
American Continent. This genus (_Ceryle_) is of wide diffusion, having
also representatives in Africa and Asia. There is thus a great contrast
with the Old World, where at least 120 species of Kingfishers are met

    portion of the inner webs towards the base white, coverts like the
    back; tail black, crossed by white bars, central rectrices edged
    with bluish grey: beneath chestnut-red; throat, centre of belly,
    and crissum white: whole length 15·0 inches, wings 7·7, tail 5·5.
    _Female_ similar, but with a broad bluish-grey pectoral band.

_Hab._ Central and South America.

This beautiful bird, the largest of the American Kingfishers, is found
throughout the greater portion of South and Central America. In the
Argentine Republic it is somewhat rare, though widely distributed,
and ranging as far south as Buenos Ayres. Dr. Döring mentions _Ceryle
torquata_ amongst the species collected by him on the Rio Negro, in
Patagonia; but it is possible that the closely allied _C. stellata_ is
meant, as this form represents the larger and more brightly-coloured
bird in the Magellanic district.

Notwithstanding its wide distribution and great beauty, little has been
recorded of the habits of this species. In Amazonia, Bartlett says:--"It
breeds in company with _Ceryle amazona_. The nest, however, is placed
very much deeper in the bank than in the case of the last-named bird,
the hole being from 4 to 6 feet in depth, with a chamber at the end
sufficiently large for the young birds when nearly full-grown."

    white, with a broad chestnut pectoral band; flanks striped with
    green; under surface of wings white; tail beneath slaty, with white
    bars on the inner webs: whole length 11·0 inches, wing 5·3, tail
    3·4. _Female_ without the red pectoral band, which is incompletely
    replaced by dark green.

_Hab._ South America.

This Kingfisher was found by White at Cosquin, where it is usually met
with along the _acequias_, or canals made for the purpose of irrigating
the cultivated lands. These canals are in places bordered with brushwood
and trees, and are tolerably deep, with a swiftly flowing current,
and abound in small fishes, so that this bird seems to prefer them as
hunting-grounds to the rocky river-bed.

In Entrerios Mr. Barrows tells us this Kingfisher is not uncommon along
the Lower Uruguay, and sometimes ascends the smaller streams a short
distance. It is much more easily approached than _C. torquata_.

_C. amazona_ is also found as far south as Buenos Ayres, where I have
always seen them singly or in pairs. Its usual cry is exceedingly
loud, hard, and abrupt, and so rapidly reiterated as to give it a sound
resembling that of a policeman's rattle. But this is not its only
language, and I was greatly surprised one day at hearing one _warbling_
long clear notes, somewhat flute-like in quality, as it flew from tree
to tree along the borders of a stream. It seems very strange that there
should be a melodious Kingfisher; but Mr. Barrows also heard the allied
_Ceryle americana_ sing, much to his surprise. My belief is, that the
birds of this group possess a singing faculty, but very rarely exercise
it; with _C. americana_ I am well acquainted, yet I never heard it utter
any note except its hard, rattling cry, resembling that of _C. amazona_,
but less powerful.

    beneath blackish, barred with white on the inner webs; throat
    white; breast chestnut-red; belly and crissum white, flanks with
    bronzy-green spots; bill and feet black: whole length 7·0 inches,
    wing 3·1, tail 2·5. _Female_ similar, but no chestnut on the breast,
    which is crossed by a bronzy-green band.

_Hab._ South America.

This is the smallest of our three Kingfishers, and nearly resembles _C.
amazona_ in plumage. Durnford found it "not uncommon" about the creeks
and streams at the mouth of the Paraná, and also obtained specimens in
the north of the Republic near Salta, during his last journey. Prof.
Burmeister met with it at Paraná and Tucuman.

Mr. Barrows gives us the following notes on this Kingfisher:--

"Resident through the year at Concepcion, but especially abundant in
winter, when it haunts the main river, the island-shores, and all the
streams, big and little. It is not in the least shy, and one once
perched in some willows directly over my boat and not 10 feet away,
while he swallowed a tiny fish he had just captured; after which he
twitted such a hearty little song that I really felt as if his proper
place must be among the _Oscines_, in spite of all anatomical defects.
On the Pampas, we found this a rather common bird on the small streams,
and its presence on some streams whose waters are entirely absorbed by
the desert before they can reach either sea or lake, first called my
attention to the presence, even in these streams, of numbers of a small
fish which is found in many of the pools as well all over the Pampas.
Although both this and the preceding species must nest about Concepcion,
I did not succeed of learning anything of the nest or eggs."


The Trogons, a family peculiar among all zygodactyle birds for having
the inner toe instead of the outer toe reversed in position, are found
in the Old World as well as in the New. But they are much more abundant
in the Tropics of America, where they number some thirty species,
and attain an astonishing development of ornamental plumage in the
celebrated Quézal (_Pharomacrus_) of Guatemala. In Argentina two stray
species only have, as yet, been recorded as met with in the northern

The Trogons are purely arboreal in habits, and frequent the larger trees
of the denser forests, feeding mainly on insects.

_Hab._ Brazil and N. Argentina.

White obtained examples of this Trogon at Campo Colorado, near Oran,
where it frequents the topmost branches of the loftiest forest-trees,
and is very difficult to discover. It is said to have a peculiar
mournful cry.

This is the only _Trogon_ included by Azara in his Birds of Paraguay. He
calls it "Surucuá," and states that it is confined to the larger forests
of that country.

White obtained a single example of this species in the forests of
Misiones, near Concepcion, in June 1881.


The Bucconidæ, or Puff-birds, are entirely restricted to the Neotropical
Region, and are most numerous in the great forests of Amazonia and
Colombia, where most of the 43 known species have been met with. These
birds seem to pass their lives sitting upon the topmost or outermost
branches of the larger trees, looking out for insects, which are
captured flying and constitute their only food. Southwards of the great
forest-districts of South America, Puff-birds become very scarce. One
species only is as yet known to occur in Paraguay, and some uncertainty

Dr. Burmeister records the occurrence of this species of Puff-bird near
Tucuman, and it must therefore be placed in our list on his authority.
But it is possible that the species which he met with may have been the
nearly allied _B. striatipectus_ of the Bolivian frontier of Brazil,
which is more likely to extend into Northern Argentina than the true
_B. maculatus_. _B. striatipectus_ (figured and described in Sclater's
'Monograph of the Jacamars and Puff-birds,' pl. xxxiii. p. 101) is very
similar to _B. maculatus_, but has the spots on the belly elongated into
long striations.

It is again possible that the _Bucco_ of Tucuman may be the Paraguayan
_B. chacuru_ of Vieillot, founded upon the "_Chacuru_" of Azara, which
is another species not remotely allied to _B. maculatus_.


The Cuckoos form an extensive and rather varied family of zygodactyle
birds with a somewhat wide distribution, being found in all parts of the
world except in the extreme north, where their insect-food would not
be abundantly met with. The true _Cuculi_, so remarkable for their
parasitic habits, are not found in the New World, but several genera of
arboreal Cuckoos (_Coccyzus_, _Piaya_, &c.), and others of terrestrial
habits (_Crotophaga_, _Geococcyx_, and _Saurothera_), are met with,
chiefly in the Neotropical Region, and number altogether some thirty
species. Of these, eight are known to occur within the confines of the
Argentine Republic.



  +Crotophaga ani+, _Scl. et Salv. Nomencl._ p. 107; _White, P. Z. S._
      1882, p. 619 (Salta).

    _Description._--Black, glossed with bronzy and purplish; bill and
    feet black; bill with the culmen much elevated, compressed and
    cultrate: whole length 13·0 inches, wing 5·5, tail 7·0. _Female_

_Hab._ Veragua and South America down to Northern Argentina.

This strange Cuckoo, with the plumage and some of the habits of a Crow,
is of a nearly uniform black, glossed with bronze, dark green, and
purple. Its most peculiar feature is the beak, which is greater in depth
than in length, and resembles an immense Roman nose, occupying the whole
face, and with the bridge bulging up above the top of the head. The
Ani is found only in the northern portion of the Argentine territory.
According to Azara it is very common in Paraguay, and goes in flocks,
associating with the Guira Cuckoo, which it resembles in its manner of
flight, in being gregarious, in feeding on the ground, and in coming a
great deal about houses; in all which things these two species differ
widely from most Cuckoos. He also says that it has a loud disagreeable
voice, follows the cattle about in the pastures like the Cow-bird, and
builds a large nest of sticks lined with leaves, in which as many as
twenty or thirty eggs are frequently deposited, several females laying
together in one nest. His account of these strange and disorderly
breeding-habits has been confirmed by independent observers in other
parts of the continent. The eggs are oval and outwardly white, being
covered with a soft white cretaceous deposit; but this can be easily
scraped off, and under it is found a smooth hard shell of a clear
beautiful blue colour.

    _Description._--Above dark brown, with white shaft-stripes; head
    brown; wings reddish brown, passing into blackish brown on the outer
    secondaries; rump white; tail white, at the base ochraceous, crossed
    by a very broad black band, except the two central feathers, which
    are uniform brown: beneath sordid white, throat and upper breast
    with long linear black shaft-stripes; bill and feet yellow: whole
    length 15·0 inches, wing 7·0, tail 8·0. _Female_ similar.

_Hab._ Brazil, Paraguay, and Argentina.

"_Piririgua_," the specific term adopted by naturalists for this bird,
is, according to Azara, the vernacular name of the species in Paraguay.
He says that in that country it is abundant, but scarce in the Plata
district. No doubt it has greatly increased and extended its range
southwards during the hundred years which have elapsed since his time,
as it is now very common in Buenos Ayres, where its vernacular name
is _Urraca_ (Magpie). In the last-named country it is not yet quite
in harmony with its environment. Everywhere its habit is to feed
exclusively on the ground, in spite of possessing feet formed for
climbing; but its very scanty plumage, slow laborious flight, and long
square tail, so unsuitable in cold boisterous weather, show that the
species is a still unmodified intruder from the region of perpetual
summer many degrees nearer to the equator.

The Guira Cuckoo is about sixteen inches long, has red eyes and blue
feet, and an orange-red beak. The crown of the head is deep rufous, and
the loose hair-like feathers are lengthened into a pointed crest. The
back and rump are white, the wings and other upper parts very dark
fuscous, marked with white and pale brown. Under surface dull white,
with hair-like black marks on the throat and breast. The tail is square,
9 to 10 inches long; the two middle feathers dark brown, the others
three-coloured--yellow at the base, the middle portion dark glossy
green, the ends white; and when the bird is flying the tail, spread out
like a fan, forms a conspicuous and beautiful object.

During the inclement winter of Buenos Ayres the Guira Cuckoo is a
miserable bird, and appears to suffer more than any other creature from
cold. In the evening the flock, usually composed of from a dozen to
twenty individuals, gathers on the thick horizontal branch of a tree
sheltered from the wind, the birds crowding close together for warmth,
and some of them roosting perched on the backs of their fellows. I have
frequently seen them roosting three deep, one or two birds at the top to
crown the pyramid; but with all their huddling together a severe frost
is sure to prove fatal to one or more birds in the flock; and sometimes
several birds that have dropped from the branch stiff with cold are
found under the trees in the morning. If the morning is fair the flock
betakes itself to some large tree, on which the sun shines, to settle
on the outermost twigs on the northern side, each bird with its wings
drooping, and its back turned towards the sun. In this spiritless
attitude they spend an hour or two warming their blood and drying the
dew from their scanty dress. During the day they bask much in the sun,
and towards evening may be again seen on the sunny side of a hedge or
tree warming their backs in the last rays. It is owing, no doubt, to
fecundity, and to an abundance of food that the Guira Cuckoo is able to
maintain its existence so far south in spite of its terrible enemy the

With the return of warm weather this species becomes active, noisy, and
the gayest of birds; the flock constantly wanders about from place to
place, the birds flying in a scattered desultory manner one behind the
other, and incessantly uttering while on the wing a long complaining
cry. At intervals during the day they also utter a kind of song,
composed of a series of long modulated whistling notes, two-syllabled,
the first powerful and vehement, and becoming at each repetition lower
and shorter, then ending in a succession of hoarse internal sounds like
the stertorous breathing of a sleeping man. When approached all the
birds break out into a chorus of alarm, with notes so annoyingly loud
and sustained, that the intruder, be it man or beast, is generally glad
to hurry out of ear-shot. As the breeding-season approaches they are
heard, probably the males, to utter a variety of soft low chattering
notes, sounding sometimes like a person laughing and crying together:
the flock then breaks up into pairs, the birds becoming silent and
very circumspect in their movements. The nest is usually built in a
thorn-tree, of rather large sticks, a rough large structure, the inside
often lined with green leaves plucked from the trees. The eggs are large
for the bird, and usually six or seven in number; but the number varies
greatly, and I have known one bird lay as many as fourteen. They
are elliptical in form and beautiful beyond comparison, being of an
exquisite turquoise-blue, the whole shell roughly spattered with white.
The white spots are composed of a soft calcareous substance, apparently
deposited on the surface of the shell after its complete formation: they
are raised, and look like snow-flakes, and when the egg is fresh laid
may be easily washed off with cold water, and are so extremely delicate
that their purity is lost on the egg being taken into the hand. The
young birds hatched from these lovely eggs are proverbial for their
ugliness, _Pichon de Urraca_ being a term of contempt commonly applied
to a person remarkable for want of comeliness. They are as unclean as
they are ugly, so that the nest, usually containing six or seven young,
is pleasant neither to sight nor smell. There is something ludicrous
in the notes of these young birds, resembling, as they do, the shrill
half-hysterical laughter of a female exhausted by over-indulgence in
mirth. One summer there was a large brood in a tree close to my home,
and every time we heard the parent bird hastening to her nest with food
in her beak, and uttering her plaintive cries, we used to run to the
door to hear them. As soon as the old bird reached the nest they would
burst forth into such wild extravagant peals and continue them so long,
that we could not but think it a rare amusement to listen to them.

According to Azara the Guira Cuckoo in Paraguay has very friendly
relations with the Ani (_Crotophaga ani_), the birds consorting together
in one flock, and even laying their eggs in one nest; and he affirms
that he has seen nests containing eggs of both species. These nests were
probably brought to him by his Indian collectors, who were in the habit
of deceiving him, and it is more than probable that in this matter they
were practising on his credulity; though it is certain that birds of
different species do sometimes lay in one nest, as I have found--the
Common Teal and the Tinamou for instance. I also doubt very much that
the bird is ever polygamous, as Azara suspected; but it frequently
wastes eggs, and its procreant habits are sometimes very irregular and
confusing, as the following case will show:--

A flock numbering about sixteen individuals passed the winter in the
trees about my home, and in spring scattered about the plantation,
screaming and chattering in their usual manner when about to breed. I
watched them, and found that after a time the flock broke up into small
parties of three or four, and not into couples, and I could not detect
them building. At length I discovered three broken eggs on the ground,
and on examining the tree overhead found an incipient nest composed of
about a dozen sticks laid crossways and out of which the eggs had been
dropped. This was in October, and for a long time no other attempt at a
nest was made; but wasted eggs were dropped in abundance on the ground,
and I continued finding them for about four months. Early in January
another incipient nest was found, and on the ground beneath it six
broken eggs. At the end of that month two large nests were made, each
nest by one pair of birds, and in the two fourteen or fifteen young
birds were reared.

When taken young the Guira Cuckoos become very tame, and make bold,
noisy, mischievous pets, fond of climbing over and tugging at the
clothes, buttons, and hair of their master or mistress. They appear to
be more intelligent than most birds, and in a domestic state resemble
the Magpie. I knew one tame that would carry off and jealously conceal
bits of bright-coloured ribbon, thread, or cloth. In a wild state their
food consists largely of insects, which they sometimes pursue running
and flying along the ground. They also prey on mice and small reptiles,
and carry off the fledglings from the nests of Sparrows and other small
birds, and in spring they are frequently seen following the plough to
pick up worms.

    _Description._--Above ashy brown, with large black shaft-spots; head
    rufous, striated with black; wings blackish, edged with brown; tail
    similar, but with slight white tips to the feathers, and the upper

_Hab._ Mexico, and Central and South America down to Argentina.

The Brown Cuckoo, called "Crispin," is found throughout the hot portion
of South America, and in different districts varies considerably in size
and colouring. It is about 12 inches long, the beak much curved; the
prevailing colour of the upper parts is light brown, the loose feathers
on the head, which form a crest, deep rufous. The upper tail-coverts are
long loose feathers of very unequal length, the longest reaching nearly
to the end of the tail. The under surface is dirty white, or dashed with

Azara says it is called _Chochi_ in Paraguay, and has a clear sorrowful
note of two syllables, which it repeats at short intervals during the
day, and also at night during the love-season. It is solitary, scarce,
and excessively shy, escaping on the opposite side of the tree when
approached, and when seen having the head and crest raised in an
attitude of alarm. In the northern part of the Argentine country it is
called _Crispin_, from its note which clearly pronounces that name. Mr.
Barrows found it common at Concepcion on the Uruguay river, and has
written the following notes about it:--

"Several were taken in open bushy places, and many others were heard. It
is a plain but attractive Cuckoo with a few-feathered crest, and long
soft flowing upper tail-coverts. The note is very clear and penetrating,
sounding much like the word 'crispin' slowly uttered, and with the
accent on the last syllable. The birds are very shy, and I followed one
for nearly an hour before I saw it at all, and nearly twice that time
before any chance of a shot was offered. There is some peculiarity in
the note which makes it impossible to tell whether the bird is in front
of or behind you--even when the note itself is distinctly heard. I know
nothing of nest or eggs."

From personal observation I can say nothing about this species, as I
never visited the district where it is found; but with the fame of the
Crispin I have always been familiar, for concerning this Cuckoo the
Argentine peasants have a very pretty legend. It is told that two
children of a woodcutter, who lived in a lonely spot on the Uruguay,
lost themselves in the woods--a little boy named Crispin and his sister.
They subsisted on wild fruit, wandering from place to place, and slept
at night on a bed of dry grass and leaves. One morning the little girl
awoke to discover that her brother had disappeared from her side. She
sprung up and ran through the woods to seek for him, but never found
him; but day after day continued wandering in the thickets calling
"_Crispin, Crispin_," until at length she was changed into a little
bird, which still flies through the woods on its never-ending quest,
following every stranger that enters them, calling after him "_Crispin,
Crispin_," if by chance it should be her lost brother.

  +Piaya cayana+, _Scl. et Salv. Nomencl._ p. 108; _Salvin, Ibis_,
      1880, p. 361 (Tucuman); _White, P. Z. S._ 1882, p. 619

    _Description._--Above deep chestnut-red: beneath pale grey, passing
    into blackish on the crissum; throat and neck pale chestnut-brown;
    tail-feathers beneath brown, more or less blackish, and, except the
    middle pair which are like the back, broadly tipped with white:
    whole length 16·0 inches, wing 5·5, tail 10·5. _Female_ similar.

_Hab._ Central and South America.

This is a widely-spread form of Cuckoo in Central and South America, and
reaches the northern territories of the Argentine Republic, having been
obtained by Durnford near Tucuman, and by White in Misiones. The whole
bird is about 18 inches long, and the tail very long in proportion,
about 11 inches. The entire plumage, except the breast and belly, which
are grey, is chestnut colour. The beak is very strong, and yellowish
green in colour; the irides, ruby-red, the eyelids scarlet.

In Colombia this Cuckoo is said to be called _Pajaro ardilla_
(Squirrel-bird), from its chestnut tint. It seems to feed chiefly, if
not altogether, on the ground, and when perched always appears awkward
and ill-at-ease. On a branch it sits motionless, until approached, and
then creeps away through the leaves and escapes on the opposite side of
the tree. This, however, is a habit common to most Cuckoos. Its language
is a loud screaming cry, on account of which the Brazilians call it
_Alma do gato_, implying that it possesses the soul of a cat. It is a
very shy retiring bird, and in this respect is more like a _Coccyzus_
than a _Guira_.

For these facts we are indebted to Léotaud, Fraser, Forbes, White, and
others; each of these observers having contributed a few words to a
history of this interesting bird's habits.

This is a well-known inhabitant of the United States, where it is a
regular summer visitant, passing the winter months in Central America
and the West Indies, and being also occasionally met with during this
season in Brazil. In the Argentine Republic it is very rare, and the few
specimens found were all seen late in the autumn, after other summer
visitors had left. I can only account for the lateness of these birds on
the supposition that, being low fliers, excessively shy, and eminently
forest birds, they shrunk from traversing the wide open plains which
offer no kind of shelter or protection, and so remained in the isolated
plantations which rise like little islands of greenery in the sea-like
level of the pampas.

    _Description._--Above pale greyish brown; head cinereous; a black
    stripe through the eyes: beneath white, more or less tinged with
    ochraceous; tail black, tipped with white; two central rectrices
    like the back; bill black: whole length 11·5 inches, wing 4·7, tail
    5·7. _Female_ similar.

_Hab._ South America.

The "Coucou," so called from its note, is the commonest species of the
genus in the Argentine Republic, and has an extensive range in South
America. In September it migrates south, and a pair or a few individuals
reappear faithfully every spring in every orchard or plantation on the
pampas. At intervals its voice is heard amidst the green trees--deep,
hoarse, and somewhat human-like in sound, the song or call being
composed of a series of notes, like the syllables _cou-cou-cou_,
beginning loud and full and becoming more rapid until at the end they
run together. It is a shy bird, conceals itself from prying eyes in the
thickest foliage, moves with ease and grace amongst the closest twigs,
and feeds principally on large winged insects, for which it searches
amongst the weeds and bushes near the ground.

The nest is the flimsiest structure imaginable, being composed of a few
dry twigs, evidently broken by the bird from the trees and not picked
up from the ground. They are laid across each other to make a platform
nest, but so small and flat is it that the eggs frequently fall out from
it. That a bird should make no better preparation than this for the
great business of propagation seems very wonderful. The eggs are three
or four in number, elliptical in form, and of a dull sea-green colour.

The Cinereous Cuckoo is smaller than the preceding species, and also
differs in having a square tail and a more curved beak. The beak is
black, and the irides blood-red, which contrasts well with the blue-grey
of the head, giving the bird a bold and striking appearance.

This species is not common, but it is, I believe, slowly extending its
range southwards, as within the last few years it has become much more
common than formerly. Like other Cuckoos, it is retiring in its habits,
concealing itself in the dense foliage, and it cannot be attracted by an
imitation of its call, an expedient which never fails with the Coucou.
Its language has not that deep mysterious, or _monkish_ quality, as it
has been aptly called, of other _Coccyzi_. Its usual song or call, which
it repeats at short intervals all day long during the love-season,
resembles the song of our little dove (_Columbula picui_), and is
composed of several long monotonous notes, loud, rather musical, but not
at all plaintive. It also has a loud harsh cry, which one finds it hard
to believe to be the voice of a Cuckoo, as in character it is more like
the scream of a Dendrocolaptine species.

The figure (Plate XIII.) is taken from a specimen of this species
obtained by Mr. Frank Withington in the Lomas de Zamora, and now in
Sclater's collection.

Of this little Cuckoo, the smallest of the genus _Coccyzus_, specimens
were obtained by Mr. Barrows at Concepcion in Entrerios, in the month of
December. The species was only previously known to occur in Venezuela
and Colombia.


In the second edition of his 'Monograph of the Toucans,' Gould admits 51
species of this fine and peculiar group, which are scattered over the
forests of Tropical America, from Southern Mexico to Northern Argentina.
Several others have been since described.

The Toucans are large birds exclusively arboreal in their habits, and
feeding mostly, if not entirely, upon fruit. A single species of wide
distribution reaches its southern limit in the forests of the northern
Argentine provinces.

Dr. Finsch's history of the Parrot tribe, published in 1867, included
accounts of about 350 species, to which at least 50 more have been added
during these last twenty years, so that upwards of 400 Parrots are now
known to science. Of these, about 150 belong to the New World, mostly to
the intertropical portion, though Parrots are found as far north as the
U.S., and as far south as Chili and Patagonia.

In the Argentine Republic the presence of ten species of Psittacidæ has
been recorded, but only two of these are found in the vicinity of Buenos
Ayres, the remaining eight being restricted to the more northern and
western portions of the country.

This Parrot, called in La Plata the Bank- or Burrowing-Parrot, from its
nesting-habits, is the only member of its order found so far south as
Patagonia. In habits it differs somewhat from most of its congeners,
and it may be regarded, I think, as one of those species which are
dying out--possibly owing to the altered conditions resulting from the
settlement of the country by Europeans. It was formerly abundant on the
southern pampas of La Plata, and being partially migratory its flocks
ranged in winter to Buenos Ayres, and even as far north as the Paraná
river. When, as a child, I lived near the capital city (Buenos Ayres),
I remember that I always looked forward with the greatest delight to
the appearance of these noisy dark-green winter visitors. Now they
are rarely seen within a hundred miles of Buenos Ayres; and I have
been informed by old gauchos that half a century before my time they
invariably appeared in immense flocks in winter, and have since
gradually diminished in numbers, until now in that district the
Bank-Parrot is almost a thing of the past. Two or three hundred miles
south of Buenos Ayres city they are still to be met with in rather large
flocks, and have a few ancient breeding-places, to which they cling very
tenaciously. Where there are trees or bushes on their feeding-ground
they perch on them; they also gather the berries of the _Empetrum
rubrum_ and other fruits from the bushes; but they feed principally on
the ground, and, while the flock feeds, one bird is invariably perched
on a stalk or other elevation to act as sentinel. They are partial
to the seeds of the giant thistle (_Carduus mariana_), and the wild
pumpkin, and to get at the latter they bite the hard dry shell into
pieces with their powerful beaks. When a horseman appears in the
distance they rise in a compact flock, with loud harsh screams, and
hover above him, within a very few yards of his head, their combined
dissonant voices producing an uproar which is only equalled in that
pandemonium of noises, the Parrot-house in the Zoological Gardens of
London. They are extremely social, so much so that their flocks do not
break up in the breeding-season; and their burrows, which they excavate
in a perpendicular cliff or high bank, are placed close together;
so that when the gauchos take the young birds--esteemed a great
delicacy--the person who ventures down by means of a rope attached to
his waist is able to rifle a whole colony. The burrow is three to five
feet deep, and four white eggs are deposited on a slight nest at the
extremity. I have only tasted the old birds, and found their flesh very
bitter, scarcely palatable.

The natives say that this species cannot be taught to speak; and it
is certain that the few individuals I have seen tame were unable to

Doubtless these Parrots were originally stray colonists from the
tropics, although now resident in so cold a country as Patagonia. When
viewed closely, one would also imagine that they must at one time have
been brilliant-plumaged birds; but either natural selection, or the
direct effect of a bleak climate, has given a sombre shade to their
colours--green, blue, yellow, and crimson; and when seen flying at a
distance, or in cloudy weather, they look as dark as crows.

_Hab._ Paraguay, Uruguay, and Argentina.

The Common Green Parrakeet, called _Cotorra_ or _Catita_ in the
vernacular, is a well-known resident species in the Argentine Republic.
It is a lively restless bird, shrill-voiced, and exceedingly vociferous,
living and breeding in large communities, and though it cannot learn
to speak so distinctly as some of the larger Parrots, it is impossible
to observe its habits without being convinced that it shares in the
intelligence of the highly-favoured order to which it belongs.

In Buenos Ayres it was formerly very much more numerous than it is now;
but it is exceedingly tenacious of its breeding-places, and there are
some few favoured localities where it still exists in large colonies, in
spite of the cruel persecution all birds easily killed are subjected to
in a country where laws relating to such matters are little regarded,
and where the agricultural population is chiefly Italian. At Mr.
Gibson's residence near Cape San Antonio, on the Atlantic coast, there
is still a large colony of these birds inhabiting the Tala woods
(_Celtis tala_), and I take the following facts from one of his papers
on the ornithology of the district.

He describes the woods as being full of their nests, with their
bright-coloured talkative denizens and their noisy chatter all day long
drowning every other sound. They are extremely sociable and breed
in communities. When a person enters the wood their subdued chatter
suddenly ceases, and during the ominous silence a hundred pairs of black
beady eyes survey the intruder from the nests and branches; and then
follows a whirring of wings and an outburst of screams that spreads the
alarm throughout the woods. The nests are frequented all the year, and
it is rare to find a large one unattended by some of the birds any
time during the day. In summer and autumn they feed principally on the
thistle; first the flower is cut up and pulled to pieces for the sake
of the green kernel, and later they eat the fallen seed on the ground.
Their flight is rapid, with quick flutters of the wings, which seem
never to be raised to the level of the body. They pay no regard to a
_Polyborus_ or _Milvago_, but mob any other bird of prey appearing in
the woods, all the Parrakeets rising in a crowd and hovering about it
with angry screams.

The nests are suspended from the extremities of the branches, to which
they are firmly woven. New nests consist of only two chambers, the
porch and the nest proper, and are inhabited by a single pair of birds.
Successive nests are added, until some of them come to weigh a quarter
of a ton, and contain material enough to fill a large cart. Thorny
twigs, firmly interwoven, form the only material, and there is no lining
in the breeding-chamber, even in the breeding-season. Some old forest
trees have seven or eight of these huge structures suspended from the
branches, while the ground underneath is covered with twigs and remains
of fallen nests. The entrance to the chamber is generally underneath,
or if at the side is protected by an overhanging eave to prevent the
intrusion of opossums. These entrances lead into the porch or outer
chamber, and the latter communicates with the breeding-chamber. The
breeding-chambers are not connected with each other, and each set is
used by one pair of birds.

The number of pairs does not exceed a dozen, even with the largest
nests. Repairs are carried on all the year round, but new nests are
only added at the approach of spring. Opossums are frequently found in
one of the higher chambers, when the entrance has been made too high,
but though they take up their abode there they cannot reach the other
chambers, and the Parrakeets refuse to go away. A species of Teal
(probably _Querquedula brasiliensis_) also sometimes occupies and breeds
in their chambers, and in one case Mr. Gibson found an opossum domiciled
in an upper chamber, Parrakeets occupying all the others except one, in
which a Teal was sitting on eggs.

The breeding-season begins about November 1, and as many as seven or
eight eggs are laid; these are dull white, very thin-shelled, elongated,
and have the greatest diameter exactly equidistant from the two ends.

Mr. Barrows speaks as follows of this species in Entrerios:--"An
abundant and familiar bird in the neighbourhood of Concepcion through
the entire year. It is commonly seen in flocks of twenty and upwards,
visiting grain-fields, gardens, &c., and sometimes, if I was correctly
informed, it has appeared in flocks of tens of thousands, completely
stripping the grain-fields. They nest in communities, many pairs uniting
in the building of a large common nest or mass of nests. I only saw
these nests on two occasions, and had no opportunity of examining their
structure. They were placed on high trees, and appeared from below to be
simply irregular masses, six or eight feet in diameter, formed of small
sticks and twigs. Where the nests are abundant the natives destroy the
young by hundreds, and the 'squabs' when nearly grown are said to be
very fine eating. The young are easily tamed, and may be taught to
articulate a few simple words."

Prof. Burmeister found this Parrakeet not uncommon on the borders of
the sierra near Mendoza. White met with it near Cosquin in the province
of Cordova, in flocks on the mountain-tops, about 3500 feet above the
sea-level. He says it is called "_Catita de las sierras_," and that
it never descends to the valleys. Its flight is very swift, and is
accompanied by a sort of chirping.

The figure (Plate XV.) is taken from a specimen in Sclater's collection,
obtained by Buckley in Bolivia.

seen specimens, in the ravines of the Sierra of Uspallata, and also met
with it in the Sierra of Cordova. It lives in small flocks, which fly
away screaming when approached.

This Parrot, which is enumerated by Azara among the birds of Paraguay,
was also found by White in the adjoining district of Misiones in
the Argentine Republic. White gives us the following notes on its
habits:--"Both in Concepcion and San Javier these Parrots are found in
incredible numbers feeding in the orange-groves which cover and enclose
the extensive Jesuit ruins of those parts of Misiones. They seem to be
very voracious, as they feed all day long; and the inhabitants shoot
them for food; but they are not easily scared, for on hearing a shot
they only fly up in clouds to descend again, meanwhile making the air
resound with their shrill cries. They can be taught to talk tolerably
well if taken young."

Durnford obtained a specimen of this Parrot near Salta in the province
of Oran, which has been identified by Mr. Salvin. It is probable that
the birds referred to _C. amazonica_ by Prof. Burmeister and White may
belong to this same species.

White obtained a single specimen of this Parrot in the dense forests of
the Rio Vermejo, near Oran, in November 1880.


About 40 different species of the nocturnal birds of prey are known
to occur in the Neotropical Region. Six of them have been recorded as
being found more or less frequently within the limits of the Argentine
Republic. Of these, the Burrowing-Owl (_Pholeoptynx cunicularia_) is one
of the most characteristic inhabitants of the Argentine Pampas, while
two others, the Barn-Owl and the Short-eared Owl, are very widely
diffused species, also well known in England.

    white, more or less suffused with tawny, except on the lower belly,
    and dotted with distinct rounded black spots; bill yellowish; tarsus
    feathered; toes slightly bristled; claws long and sharp: whole
    length 15·0 inches, wing 12·5, tail 5·0. _Female_ similar.

_Hab._ Old and New Worlds.

This widely distributed species is found throughout South America; and
in its habits and sepulchral voice, as well as in its pretty reddish
buff, grey, and white plumage, is identical with the European bird.
D'Orbigny expressed astonishment that this Owl, which is never seen in
uninhabited places, invariably appears to keep company with man wherever
a settlement is formed, even in the most lonely and isolated spots.
Probably it is much more numerous than most people imagine, sheltering
itself everywhere in caverns and hollow trees, so that it is always
present, and ready to take early advantage of the commodious
church-tower or other large building raised by man. On the level pampas,
where there are no hills or suitable hiding-places, it is rarely seen:
it is exclusively a town bird.

Nothing more need be said of the habits of a species so well known, and
about which there is so much recorded in general works of Natural

_Hab._ Old and New Worlds.

The Short-eared Owl is found throughout the Argentine country, where
it is commonly called _Lechuzon_ (big Owl) in the vernacular. Like the
species last described--the Barn-Owl--it has an exceedingly wide range.
It is found throughout the continent of Europe; it also inhabits Asia
and Africa, many of the Pacific Islands, and both Americas, from Canada
down to the Straits of Magellan. Such a very wide distribution would
seem to indicate that it possesses some advantage over its congeners,
and is (as an Owl) more perfect than others. It is rather more diurnal
in its habits than most Owls, and differs structurally from other
members of its order in having a much smaller head. It is also usually
said to be a weak flier; but this I am sure is a great mistake, for it
seems to me the strongest flier amongst Owls, and very migratory in its
habits, or, at any rate, very much given to wandering. Probably its very
extensive distribution is due in some measure to a greater adaptability
than is possessed by most species; also to its better sight in the
daytime, and to its wandering disposition, which enables it to escape a
threatened famine, and to seize on unoccupied or favourable ground.

The bird loves an open country, and sits by day on the ground concealed
amongst the herbage or tall grass. An hour before sunset it quits its
hiding-place, and is seen perched on a bush or tall stalk, or sailing
about a few feet above the ground with a singularly slow, heron-like
flight; and at intervals while flying it smites its wings together under
its breast in a quick sudden manner. It is not at all shy, the intrusion
of a man or dog in the field it frequents only having the effect of
exciting its indignation. An imitation of its cry will attract all the
individuals within hearing about a person, and any loud unusual sound,
like the report of a gun, produces the same effect. When alarmed or
angry it utters a loud hiss, and at times a shrill laugh-like cry. It
also has a dismal scream, not often heard; and at twilight hoots, this
part of its vocal performance sounding not unlike the distant baying of
a mastiff or a bloodhound. It breeds on the ground, clearing a circular
spot, and sometimes, but not often, lining it with a scanty bed of dry
grass. The eggs are three or four, white, and nearly spherical.

The Short-eared Owl was formerly common everywhere on the pampas, where
the coarse indigenous grasses afforded the shelter and conditions best
suited to it. When in time this old rough vegetation gave place to the
soft perishable grasses and clovers, accidentally introduced by European
settlers, the Owl disappeared from the country, like the large
Tinamou (_Rhynchotis rufescens_), the Red-bellied Finch (_Embernagra
platensis_), and various other species; for the smooth level plains
afforded it no shelter. Now, however, with the spread of cultivation,
it has reappeared, and is once more becoming a common bird in the more
thickly-settled districts.

This bird, eagle-like in its dimensions, and the largest of our Owls, is
found throughout both Americas, though some authors, relying on certain
trivial variations in size and colour, have separated the southern from
the northern form, and called it _Bubo magellanicus_. In the Argentine
Republic it is well known by its Indian name "Ñacurutú"; also in
Paraguay according to Azara, who says:--"It pronounces its own name in
tones which scare such as pass by night through the deep woods, which
are its palaces."

The habits of the Virginian Owl are too well known to need to be
rewritten in this place: the ornithologists of North America have
supplied several biographies of it, that by Audubon being specially

    _Description._--Above brown, vermiculated with darker brown, and

    narrow zigzag lines of blackish brown: whole length 9·5 inches, wing
    6·2, tail 3·7. _Female_ similar, but rather larger.

_Hab._ South America.

Azara and d'Orbigny have described the habits of this Owl, which is
common in Paraguay and in the Argentine State of Corrientes, the name
for it in both countries being _Choliba_. It is a bird of the
woods, strictly nocturnal, lives in pairs, and spends the day in a
thick-foliaged tree, the male and female sitting close together. At
night it comes a great deal about houses, where it diligently explores
every corner in search of cockroaches and other vermin, and in this way
commends itself to the country people, who esteem it highly, and often
keep it tame in their homes. Its hoot, described as sounding like
_tururú-tú-tú_, is not unpleasant to the ear, and is a familiar sound to
all who traverse the woody paths by night. It breeds in deep woods, and
lays three white eggs in a hollow tree without any nest.

Barrows found it common in Corrientes along the wooded water-courses,
and says it has a soft tremulous cry. He tells us there are two
varieties of it in colour, red and grey, and gives _Caburé_ as the
native name.

The Burrowing-Owl is abundant everywhere on the pampas of Buenos Ayres
and avoids woods, but not districts abounding in scattered trees and
bushes. It sees much better than most Owls by day, and never affects
concealment nor appears confused by diurnal sounds and the glare of
noon. It stares fixedly--"with insolence," Azara says--at a passer-by,
following him with the eyes, the round head turning about as on a pivot.
If closely approached it drops its body or bobs in a curious fashion,
emitting a brief scream, followed by three abrupt ejaculations; and if
made to fly goes only fifteen or twenty yards away, and alights again
with face towards the intruder; and no sooner does it alight than it
repeats the odd gesture and scream, standing stiff and erect, and
appearing beyond measure astonished at the intrusion. By day it flies
near the surface with wings continuously flapping, and invariably before
alighting glides upwards for some distance and comes down very abruptly.
It frequently runs rapidly on the ground, and is incapable of sustaining
flight long. Gaucho boys pursue these birds for sport on horseback,
taking them after a chase of fifteen or twenty minutes. They live in
pairs all the year, and sit by day at the mouth of their burrow or on
the Vizcacha's mound, the two birds so close together as to be almost
touching; when alarmed they both fly away, but sometimes the male only,
the female diving into the burrow. On the pampas it may be more from
necessity than choice that they always sit on the ground, as they are
usually seen perched on the summits of bushes where such abound, as in

These are the commonest traits of the Burrowing-Owl in the settled
districts, where it is excessively numerous and has become familiar with
man; but in the regions hunted over by the Indians it is a scarce bird
and has different habits. Shy of approach as a persecuted game fowl, it
rises to a considerable height in the air when the approaching traveller
is yet far off, and flies often beyond sight before descending again to
the earth. This wildness of disposition is, without doubt, due to
the active animosity of the pampas-tribes, who have all the ancient
wide-spread superstitions regarding the Owl. Sister of the Evil Spirit
is one of their names for it; they hunt it to death whenever they can,
and when travelling will not stop to rest or encamp on a spot where an
Owl has been spied. Where the country is settled by Europeans the
bird has dropped its wary habits and become extremely tame. They are
tenacious of the spot they live in, and are not easily driven out by
cultivation. When the fields are ploughed up they make their kennels on
their borders, or at the roadsides, and sit all day perched on the posts
of the fences.

Occasionally they are seen preying by day, especially when anything
passes near them, offering the chance of an easy capture. I have often
amused myself by throwing bits of hard clay near one as it sat beside
its kennel; for the bird will immediately give chase, only discovering
its mistake when the object is firmly clutched in its talons. When there
are young to be fed, they are almost as active by day as by night. On
hot November days multitudes of a large species of _Scarabæus_ appear,
and the bulky bodies and noisy bungling flights of these beetles invite
the Owls to pursuit, and on every side they are seen pursuing, and
striking down the beetles, and tumbling upon them in the grass. Owls
have a peculiar manner of taking their prey: they grapple it so tightly
in their talons that they totter and strive to steady themselves by
throwing out their wings, and, sometimes losing their balance, fall
prostrate and flutter on the ground. If the animal captured be small
they proceed after a while to dispatch it with the beak; if large they
usually rise laboriously from the ground and fly to some distance with
it, thus giving time for the wounds inflicted by the claws to do their

At sunset the Owls begin to hoot; a short followed by a long note is
repeated many times with an interval of a second of silence. There is
nothing dreary or solemn in this performance; the voice is rather soft
and sorrowful, somewhat resembling the lowest notes of the flute in
sound. In spring they hoot a great deal, many individuals responding to
each other.

In the evening they are often seen hovering at a height of forty feet
above the surface, and continuing to do so fully a minute or longer
without altering their position. They do not drop the whole distance at
once on their prey, but descend vertically, tumbling and fluttering as
if wounded, to within ten yards of the earth, and then, after hovering
a few seconds more, glide obliquely on to it. They prey on every living
creature not too large to be overcome by them. Sometimes when a mouse is
caught they tear off the head, tail, and feet, devouring only the body.
The hind quarters of toads and frogs are almost invariably rejected; and
inasmuch as these are the most fleshy and succulent parts, this is a
strange and unaccountable habit. They make an easy conquest of a snake
eighteen inches long, and kill it by dealing it blows with the beak,
hopping briskly about it all the time, apparently to guard themselves
with their wings. They prey largely on the common _Coronella anomala_,
but I have never seen one attacking a venomous species. When they have
young many individuals become destructive to poultry, coming about the
houses and carrying off the chickens and ducklings by day. In seasons of
plenty they destroy far more prey than they can devour; but in severe
winters they come, apparently starving, about the houses, and will then
stoop to carry off any dead animal food, though old and dried up as a
piece of parchment. This I have often seen them do.

Though the Owls are always on familiar terms with the Vizcachas
(_Lagostomus trichodactylus_) and occasionally breed in one of
their disused burrows, as a rule they excavate a breeding-place for
themselves. The kennel they make is crooked, and varies in length
from four to twelve feet. The nest is placed at the extremity, and is
composed of wool or dry grass, often exclusively of dry horse-dung.
The eggs are usually five in number, white, and nearly spherical; the
number, however, varies, and I have frequently found six or seven eggs
in a nest. After the female has begun laying the birds continue carrying
in dry horse-dung, until the floor of the burrow and a space before it
is thickly carpeted with this material. The following spring the loose
earth and rubbish is cleared out, for the same hole may serve them
two or three years. It is always untidy, but mostly so during the
breeding-season, when prey is very abundant, the floor and ground about
the entrance being often littered with excrements, green beetle-shells,
pellets of hair and bones, feathers of birds, hind quarters of frogs
in all stages of decay, great hairy spiders (_Mygale_), remains of
half-eaten snakes, and other unpleasant creatures that they subsist on.
But all this carrion about the little Owl's disordered house reminds one
forcibly of the important part the bird plays in the economy of nature.
The young birds ascend to the entrance of the burrow to bask in the sun,
and receive the food their parents bring; when approached they become
irritated, snapping with their beaks, and retreat reluctantly into the
hole; and for some weeks after leaving it they make it a refuge from
danger. Old and young birds sometimes live together for four or five
months. I believe that nine-tenths of the Owls on the pampas make
their own burrows, but as they occasionally take possession of the
forsaken holes of mammals to breed in, it is probable that they would
always observe this last habit, if suitable holes abounded, as on
the North-American prairies inhabited by the marmot. Probably our
Burrowing-Owl originally acquired the habit of breeding in the ground in
the open level regions it frequented; and when this habit (favourable
as it must have been in such unsheltered situations) had become
ineradicable, a want of suitable burrows would lead it to clean out such
old ones as had become choked up with rubbish, to deepen such as were
too shallow, and ultimately to excavate for itself. The mining instinct
varies greatly in strength, even on the pampas. Some pairs, long mated,
only begin to dig when the breeding-season is already on them; others
make their burrows as early as April--that is six months before the
breeding-season. Generally both birds work, one standing by and
regarding operations with an aspect of grave interest, and taking its
place in the pit when the other retires; but sometimes the female has no
assistance from her partner, and the burrow then is very short. Some
pairs work expeditiously and their kennel is deep and neatly made;
others go about their task in a perfunctory manner, and begin, only to
abandon, perhaps half a dozen burrows, and then rest two or three weeks
from their unprofitable labours. But whether industrious or indolent,
by September they all have their burrows made. I can only account for
Azara's unfortunate statement, repeated since by scores of compilers,
that the Owl never constructs its own habitations, by assuming that
a century ago, when he lived and the country was still very sparsely
settled, this Owl had not yet become so abundant or laid aside the wary
habit the aborigines had taught it, so that he did not become very
familiar with its habits.

_Hab._ La Plata, Patagonia, and Chili.

This diminutive Owl, which barely reaches eight inches in length, and is
light brown and grey in colour, was discovered by Captain King in 1827
in the neighbourhood of the Straits of Magellan. I met with it on the
Rio Negro in Patagonia, but saw very little of it. It struck me that,
like the Burrowing-Owl, it is not very strictly nocturnal, for I
observed it in the daytime perched in exposed situations.

In 1882 White met with it in Cosquin, in Cordova, and made the following
important note on its habits:--"It causes the naturalist much amusement
to watch the habits of this pretty little Owl, that, perched perfectly
motionless on a branch, utters such a sirenic cry as to attract little
birds in great numbers. They are observed to cluster round it, all the
while fluttering and in great excitement, charmed by some fascination.
After waiting a while the Owl suddenly pounces upon the nearest for its

I also observed little birds mobbing it, when it perched in a
conspicuous place in the daytime, as they always mob small birds of
prey, but was not so fortunate as to hear the "sirenic cry" with which
the Cordova bird fascinates its victims. One has heard this yarn of a
"sirenic cry" before, of other species, for it is a very common myth.
That an Owl should now be fitted with the old melodious cap seems
strange; and Mr. White is in error when he says that this habit in our
bird "causes the _naturalist_ much amusement."



The diurnal birds of prey of the family Falconidæ found in the
Neotropical Region number about 110 species, of which 22 are at present
known to occur within the limits of the present work. It is probable,
however, that many additional species of this group will be hereafter
added to the Argentine list.

As is usually the case with the Accipitres, most of the species have an
extensive distribution.

This Harrier is found throughout the Argentine Republic, and is also
common in Patagonia and the Falkland Islands. On the pampas it is, I
think, the most common bird of prey, after the excessively abundant
_Milvago chimango_. Like the Chimango, it also prefers an open unwooded
country, and resembles that bird not a little in its general appearance,
and when in the brown stage of plumage may be easily mistaken for it. In
the Falklands it has even acquired the Carrion Hawk's habits, for
Darwin distinctly saw one feeding on a carcass there, very much to his
surprise. On the pampas I have always found it a diligent bird-hunter,
and its usual mode of proceeding is to drive up the bird from the grass
and to pursue and strike it down with its claws. Mr. Gibson's account of
its habits agrees with mine, and he says that "it will raise any small
bird time after time, should the latter endeavour to conceal itself in
the grass, preferring, as it would seem, to strike it on the wing." He
further says:--"Its flight is low and rather rapid, while if its quarry
should double it loses no ground, for it turns something in the manner
of a Tumbler Pigeon, going rapidly head over heels in the most eccentric
and amusing fashion."

Probably this Harrier has a partial migration, as a great many are
always seen travelling across the pampas in the autumn and spring; many
individuals, however, remain all winter.

The nest is made on the ground among long grass, or in reed-beds in
marshy places, and the eggs are white blotched with dark red.

This brown-plumaged, short-winged, and exceedingly vociferous Hawk is
common in the woods along the shores of the Plata and its tributaries,
and is never found far removed from water. It perches on the summit of a
tree, and sits there motionless for hours at a time, and at intervals
utters singularly long loud cries, which become more frequent and
piercing when the bird is disturbed, as by the approach of a person.
Its flight is rapid and irregular, the short blunt wings beating
unceasingly, while the bird pours out a succession of loud vehement
broken screams.

Mr. Barrows observed it on the Lower Uruguay, and writes:--"It feeds
largely if not exclusively on fish, nearly every specimen having
their remains (and nothing else) in their stomachs." It would be very
interesting to learn how it captures its prey.

The figure given herewith (Plate XVI.) represents a fine adult female
specimen of this Buzzard, obtained by Mr. Frank Withington at Lomas de
Zamora, on the 4th of February, 1886, and now in Sclater's collection.

Swainson's Buzzard is a North-American species, which has only
recently been ascertained to occur in the southern part of the Western
Hemisphere. Full details concerning it are given in the standard work on
"North-American Land-birds," to which we have referred above. Messrs.
Baird, Brewer, and Ridgway divide the species into two subspecies,
"_swainsoni_" and "_oxypterus_" to the latter of which they refer the
southern specimens, but they acknowledge that it is "difficult to
express points of absolute difference" between these subspecies.

It appears from what these authorities say (_l. c._ p. 268) that a
young specimen procured by Hudson at Conchitas in 1860, and referred
by Messrs. Salvin and Sclater with doubt to _B. albicaudatus_, really
belongs to _B. swainsoni_. A second undoubtedly Argentine example is
that procured by Mr. Withington and now figured.

Like other Buzzards, _B. swainsoni_ varies much in plumage, and
occasionally assumes a melanistic form, under which it was described and
figured by Sclater in 1858 as _Buteo fuliginosus_ (_cf._ P. Z. S. 1858,
p. 356, and Trans. Zool. Soc. vol. iv. p. 267, pl. lxii.). Mr. Gurney is
of opinion that d'Orbigny's _Buteo unicolor_ is also referable to this
form of _B. swainsoni_ (_cf._ Ibis, 1889, p. 134).

A well-known writer on North-American birds (Capt. C. E. Bendire) gives
the following account of the nesting of _Buteo swainsoni_ in Arizona:--

"This species is by far the commonest Hawk in the vicinity of Fort
Huachuca, and a resident throughout the year. Lieutenant Benson found
not less than forty-one of their nests containing eggs between May 14
and June 18, 1887. These were all placed in low mesquite trees and
bushes, from 3 to 15 feet from the ground. Only six of these nests
contained three eggs each, twenty-one nests contained two eggs, the
remaining fourteen but a single egg. Many of the latter were undoubtedly
laid by birds that had been robbed before, especially where the same
nest was used again, which was frequently the case, and a few were
uncompleted sets. Two eggs is the usual number laid by these birds, in
Arizona at least. The nests were bulky platforms, composed of sticks of
various sizes, with but a slight depression in the centre, and sparingly
lined with a few bunches of dried grass. Lieutenant Benson writes me
that after the Arkansas King-birds (_Tyrannus verticalis_, Say) began to
build he invariably found one of their nests in any tree that contained
a Swainson's Hawk's nest. In one case, a pair of these birds had placed
their nest directly under, and but 8 or 9 inches from that of the Hawk.
A pair of White-rumped Shrikes (_Lanius ludovicianns excubitoroides_)
built also immediately below one of these Hawk's nests.

"When not closely looked at, many of the eggs of Swainson's Hawk appear
to be unspotted, but on careful examination there are in reality but
very few that are immaculate. Out of a series of sixty-nine specimens
sent by Lieutenant Benson there are but three unspotted ones. The
ground-colour of these eggs when fresh is a very distinct greenish
white, which in course of time fades into a dull yellowish white, even
if the eggs are not exposed to light. They are more or less heavily
spotted and blotched, varying in colour from burnt-umber to tawny olive,
and in some of the lighter coloured specimens from a French grey to a
drab-grey. Their shape ranges from a short ovate to an oval, and they
average about 2·23 by 1·71 inches in length and width."

_Hab._ Southern and Central America.

This Buzzard does not breed on the pampas, where I have observed it, but
appears there in the spring and autumn, irregularly, when migrating,
and in flocks which travel in a loitering, desultory manner. The flocks
usually number from thirty or forty to a hundred birds, but sometimes
many more. I have seen flocks which must have numbered from one to two
thousand birds. When flying the flock is very much scattered, and does
not advance in a straight line, but the birds move in wide circles at
a great height in the air, so that a person on horseback travelling at
a canter can keep directly under them for two or three hours. On the
ground one of these large flocks will sometimes occupy an area of half
a square league, so widely apart do the birds keep. I have dissected a
great many and found nothing but coleopterous insects in their stomachs;
and indeed they would not be able to keep in such large companies when
travelling if they required a nobler prey.

At the end of one summer a flock numbering about two hundred birds
appeared at an estancia near my home, and though very much disturbed
they remained for about three months, roosting at night on the
plantation trees, and passing the day scattered about the adjacent
plain, feeding on grasshoppers and beetles. This flock left when the
weather turned cold; but at another estancia a flock appeared later in
the season and remained all winter. The birds became so reduced in flesh
that after every cold rain or severe frost numbers were found dead under
the trees where they roosted; and in that way most of them perished
before the return of spring.

This is a fine bird--the king of South-American Buzzards. In the adult
female the three colours of the plumage are strongly contrasted; the
back being rusty rufous, the rest of the upper parts grey, the whole
under surface pure white. It is occasionally met with in the northern
provinces of the Argentine Republic, but is most common in Patagonia;
and it has been said that in that region it takes the place of the
nearly allied _Buteo albicaudatus_ of Brazil. In habits, however, the
two species are as different as it is possible for two raptores to be;
for while the northern bird has a cowardly spirit, is, to some extent,
gregarious, and feeds largely on insects, the Patagonian species has the
preying habits of the Eagle, and lives exclusively, I believe, or
nearly so, on cavies and other small mammals. When Captain King first
discovered it in 1827, he described it as "a small beautiful Eagle." In
Patagonia it is very abundant, and usually seen perched on the summit of
a bush, its broad snowy-white bosom conspicuous to the eye at a great
distance--one of the most familiar features in the monotonous landscape
of that grey country. The English colonists on the Chupat, Durnford
says, call it the "white horse," owing to its conspicuous white colour
often deceiving them when they are out searching for strayed horses
in the hills. It is a wary bird, and when approached has the habit of
rising up in widening circles to a vast height in the air. When sailing
about in quest of prey it usually maintains a height of fifty or
sixty yards above the surface. The stomachs of all the individuals I
have examined contained nothing but the remains of cavies (_Cavia

The nest is built on the top of a thorn bush, and is a large structure
of sticks, lined with grass, fur, dry dung, and other materials. "The
eggs are greyish white in colour, blotched and marked, principally
towards the large end, with two shades of umber-brown" (_Gould_).

This is the Common Buzzard of the Plata region. It differs from the
species previously described in its greater length of wing, and in the
habit of flying near the ground when in search of prey; resembling in
this respect a Harrier, only its flight is slower and more loitering. It
prefers an open country, but on the pampas, like all large Hawks, it
meets with great persecution from the ever-vigilant, fierce-tempered
Spur-winged Lapwing. I once saw one of these Buzzards, while being so
persecuted, make a conquest which greatly surprised me. It was sailing
over the plain, about twenty feet from the surface, harried by several
Lapwings, when suddenly, just as one Lapwing swept downwards past it in
the usual way, apparently missing the head of the Hawk with its sharp
wing-spurs by a hair's breadth, the Buzzard struck at and seized it in
its claws and bore it to the ground. The screams of the captive and its
fellows quickly brought to the spot a cloud of two or three hundred
Lapwings, all hovering and screaming their loudest. I ran to the spot to
aid in the rescue, when seeing me coming the Buzzard rose heavily from
the ground, still carrying the Plover, and flew away beyond reach.

and is also found in the woods and marshes along the Plata basin,
ranging south to Buenos Ayres. The wings are larger and the flight
slower than in the last species. The plumage is nearly of a uniform
dark brown.

At Concepcion, in Entrerios, Mr. Barrows tells us it is not unfrequently
seen in cold weather. In July 1880, during an almost unprecedented rise
of the river, it was quite abundant. The stomach of a gorged female
examined contained only young grasshoppers.

The Grey or Chilian Eagle, like most diurnal birds of prey, undergoes
many changes of colour, the plumage at different periods having its
brown, black, and grey stages: in the old birds it is a uniform clear
grey, and the under surface white. Throughout the Argentine country
this is the commonest Eagle, and I found it very abundant in Patagonia.
D'Orbigny describes it with his usual prolixity--pardonably so in this
case, however, the bird being one of the very few species with which he
appears to have become familiar from personal observation. He says that
it is a wary bird; pairs for life, the male and female never being found
far apart; and that it soars in circles with a flight resembling that
of a Vulture, and that the form of its broad blunt wings increases its
resemblance to that bird. Cavies and small mammals are its usual prey;
and in the autumn and winter, when the Pigeons congregate in large
numbers, it follows their movements. During the Pigeon-season, he has
counted as many as thirty Eagles in the course of a three leagues' ride;
and he has frequently seen an Eagle swoop down into a cloud of Pigeons,
and invariably reappear with one struggling in its talons. It is seldom
found far from the shores of the sea or of some large river; and on the
Atlantic coast, in Patagonia, it soars above the sands at ebb-tide,
looking out for stranded fish, carcases of seals, and other animal food
left by the retiring waters, and quarrels with Condors and Vultures
over the refuse, even when it is quite putrid. It acts as a weather
prognostic, and before a storm is seen to rise in circles to a vast
height in the air, uttering piercing screams, which may be heard after
it has quite disappeared from sight.

The nest of this species is usually built on the ledge of an
inaccessible rock or precipice, but not unfrequently on a tree. Mr.
Gibson describes one, which he found on the top of a thorn-tree, as a
structure of large sticks three feet in diameter, the hollow cushioned
with dry grass. It contained two eggs, dull white, marked with pale
reddish blotches.

Mr. Gibson compares its cry to a "wild human laugh," and also
writes:--"Its whereabouts may often be detected by an attendant flock
of Caranchos (_Polyborus tharus_), particularly in the case of a young
bird. As soon as it rises from the ground or from a tree, these begin to
persecute it, ascending spirally also, and making dashes at it, while
the Eagle only turns its head watchfully from side to side, the mere
action being sufficient to avert the threatened collision."

Gay, in his 'Natural History of Chili,' describes the affectionate and
amusing habits of an Eagle of this species which he had tamed. It took
great delight in playing with his hand, and would seize and pretend to
bite one of his fingers, but really with as much tenderness as a playful
dog displays when pretending to bite its master. It used also to amuse
itself by picking up a pebble in its beak, and with a jerk of its head
toss it up in the air, then seize it in its claws when it fell, after
which it would repeat the performance.

I met with this fine Eagle on the Rio Negro, in Patagonia, where
d'Orbigny also found it; the entire Argentine Territory comes, however,
within its range. Having merely seen it perched on the tall willows
fringing the Rio Negro, or soaring in wide circles far up in the sky, I
cannot venture to speak of its habits, while the account of them which
d'Orbigny built up is not worth quoting, for he does not say how he got
his information. One of his statements would, if true, be very important
indeed. He says that his attention was drawn to a very curious fact
concerning the Crowned Harpy, which was, that this bird preys chiefly on
the skunk--an animal, he very truly adds, with so pestilential an odour
that even the most carnivorous of mammals are put to flight by it; that
it is the only bird of prey that kills the skunk, and that it does so by
precipitating itself from a vast height upon its quarry, which it then
quickly despatches. It would not matter at all whether the Eagle dropped
from a great or a moderate height, for in either case the skunk would
receive its enemy with the usual pestilent discharge. D'Orbigny's
account is, however, pure conjecture, and though he does not tell us
what led him to form such a conclusion, I have no doubt that it was
because the Eagle or Eagles he obtained had the skunk-smell on their
plumage. Most of the Eagles I shot in Patagonia, including about a dozen
Chilian Eagles, smelt of skunk, the smell being in most cases old and
faint. Of two Crowned Harpies obtained, only one smelt of skunk. This
only shows that in Patagonia Eagles attack the skunk, which is not
strange, considering that it is of a suitable size and conspicuously
marked; that it goes about fearlessly in the daytime and is the most
abundant animal, the small cavy excepted, in that sterile country. But
whether the Eagles _succeed_ in their attacks on it is a very different
matter. The probability is that when an Eagle, incited by the pangs of
hunger, commits so great a mistake as to attack a skunk, the pestilent
fluid, which has the same terribly burning and nauseating effects on the
lower animals as on man, very quickly makes it abandon the contest. It
is certain that pumas make the same mistake as the Eagles do, for in
some that are caught the fur smells strongly of skunk. It might be said
that the fact that many Eagles smell of skunk serves to show that they
do feed on them, for otherwise they would learn by experience to avoid
so dangerous an animal, and the smell of a first encounter would soon
wear off. I do not think that hungry birds of prey, in a barren country
like Patagonia, would learn from one repulse, or even from several,
the fruitlessness and danger of such attacks; while the smell is so
marvellously persistent that one or two such attacks a year on the part
of each Eagle would be enough to account for the smell on so many birds.
If skunks could be easily conquered by Eagles, they would not be so
numerous or so neglectful of their safety as we find them.

A fine example of this bird was brought alive from the Argentine
Republic to England by Mr. E. W. Goodlake in 1863, and lived for several
years in the Zoological Society's Gardens.

The Peregrine Falcon is found throughout the Argentine Republic, but
is nowhere numerous, and is not migratory; nor is it "essentially a
duck-hawk," as in India according to Dr. Anderson, for, it preys chiefly
on land birds. It is solitary, and each bird possesses a favourite
resting-place or _home_, where it spends several hours every day, and
also roosts at night. Where there are trees it has its chosen site where
it may always be found at noon; but on the open treeless pampas a mound
of earth or the bleached skull of a horse or cow serves it for a perch,
and here for months the bird may be found every day on its stand. It
sits upright and motionless, springs suddenly into the air when taking
flight, and flies in a straight line, and with a velocity which few
birds can equal. Its appearance always causes great consternation
amongst other birds, for even the Spur-winged Lapwing, the spirited
persecutor of all other Hawks, flies screaming with terror from it. It
prefers attacking moderately large birds, striking them on the wing,
after which it stoops to pick them up. While out riding one day, I saw a
Peregrine sweep down from a great height and strike a Burrowing-Owl to
the earth, the Owl having risen up before me. It then picked it up and
flew away with it in its talons.

The Peregrine possesses one very curious habit. When a plover, pigeon,
or duck is killed, it eats the skin and flesh of the head and neck,
picking the vertebræ clean of the flesh down to the breast-bone, and
also eating the eyes, but leaving the body untouched. I have found
scores of dead birds with head and neck picked clean in this way; and
once I watched for some months a Peregrine which had established itself
near my home, where it made havoc among the Pigeons; and I frequently
marked the spot to which it carried its prey, and on going to the place
always found that the Pigeon's head and neck only had been stripped
of flesh. The Burrowing-Owl has an analogous habit, for it invariably
rejects the hind quarters of the toads and frogs which it captures.

At the approach of the warm season the Peregrines are often seen in twos
and threes violently pursuing each other at a great height in the air,
and uttering shrill piercing screams, which can be heard distinctly
after the birds have disappeared from sight.

The Orange-chested Hobby is found throughout South and Central America,
but the form met with here differs, to some extent, in habits from its
representatives of the hotter region. It is a Patagonian bird, the
most common Falcon in that country, and is migratory, wintering in the
southern and central Argentine provinces. In its winter home it is
solitary, and fond of hovering about farm-houses, where it sits on a
tree or post and looks out for its prey. Compared with the Peregrine
it has a very poor spirit, and I have often watched it give chase to
a bird, and just when it seemed about to grasp its prey, give up the
pursuit and slink ingloriously away. It never boldly and openly attacks
any bird, except of the smallest species, and prefers to perch on an
elevation from which it can dart down suddenly and take its prey by

The nest is a slovenly structure of sticks on a thorny bush or tree.
The eggs, which I have not seen, Darwin describes as follows:--"Surface
rough with white projecting points; colour nearly uniform dirty
wood-brown; general appearance as if it had been rubbed in brown mud."

    _Description._--Above cinnamon-red, with irregular black cross bands
    on the back; head bluish grey; front and sides of head white; nape
    and stripes on the sides of the neck black; wings bluish grey with
    black central spots; remiges black, with numerous white cross bars

The habits of this little Falcon closely resemble those of _Falco
fusco-cærulescens_, and like that bird it is common in Patagonia and
migrates north in winter. Many individuals, however, do not migrate, as
I found when residing at the Rio Negro, where some pairs remained at
the breeding-place all the year. Many pairs are also found resident and
breeding in other parts of the Argentine country, but it is common only
in Patagonia.

It nests in holes in cliffs and also on trees, and sometimes builds its
own nest on the large nest of a Dendrocolaptine bird or of a Parroquet.
It lays four eggs, large for the size of the bird, oval in shape, and
white in colour, thickly blotched with dull red.

The preying habits of the Little Kestrel are similar to those of the
Orange-chested Hobby; it haunts farm-houses and plantations, and spends
a great deal of time perched on some elevation watching for its prey,
and making sudden dashes to capture it by surprise. But though not bold
when seeking its food, it frequently makes violent unprovoked attacks
on species very much larger than itself, either from ill-temper or in a
frolicsome spirit, which is more probable.

Thus I have seen one drive up a flock of Glossy Ibises and pursue them
some distance, striking and buffeting them with the greatest energy. I
saw another pounce down from its perch, where it had been sitting for
some time, on a female skunk quietly seated at the entrance of her
burrow, with her three half-grown young frolicking around her. I was
watching them with intense interest, for they were leaping over their
parent's tail, and playing like kittens with it, when the Hawk dashed
down, and after striking at them quickly three or four times, as they
tumbled pell-mell into their kennel, flew quietly away, apparently well
satisfied with its achievement.

This interesting Hawk is found throughout the Argentine Republic, but is
nowhere numerous. It also inhabits Chili, where, Gay says, it is called
_Bailarin_ (dancer) on account of its aerial performances. It is a
handsome bird, with large ruby-red irides, and when seen at a distance
its snow-white plumage and buoyant flight give it a striking resemblance
to a gull. Its wing-power is indeed marvellous. It delights to soar,
like the Martens, during a high wind, and will spend hours in this
sport, rising and falling alternately, and at times, seeming to abandon
itself to the fury of the gale, is blown away like thistle-down, until,
suddenly recovering itself, it shoots back to its original position.
Where there are tall poplar trees these birds amuse themselves by
perching on the topmost slender twigs, balancing themselves with
outspread wings, each bird on a separate tree, until the tree-tops
are swept by the wind from under them, when they often remain poised
almost motionless in the air, until the twigs return to their feet.

When looking out for prey, this Kite usually maintains a height of
sixty or seventy feet above the ground, and in its actions strikingly
resembles a fishing gull, frequently remaining poised in the air with
body motionless and wings rapidly vibrating for fully half a minute at
a stretch, after which it flies on or dashes down upon its prey.

The nest is placed on the topmost twigs of a tall tree, and is round and
neatly built of sticks, rather deep, and lined with dry grass. The eggs
are eight in number, nearly spherical, the ground-colour creamy white,
densely marked with longitudinal blotches or strips of a fine rich red,
almost like coagulated blood in hue. There is, however, great variety in
the shades of the red, also in the disposition of the markings, these in
some eggs being confluent, so that the whole shell is red. The shell is
polished and exceedingly fragile, a rare thing in the eggs of a raptor.

An approach to the nest is always greeted by the birds with long
distressful cries, and this cry is also muttered in the love-season,
when the males often fight and pursue each other in the air. The old
and young birds sometimes live together until the following spring.

    _Description._--Blackish slate-colour; head and wing-feathers black;

    but leaving the tail end greyish; bill orange, apical half black;

    13·0, tail 7·5. _Female_ similar, but rather larger.

_Hab._ South America.

This Hawk in size and manner of flight resembles a Buzzard, but in its
habits and the form of its slender and very sharply hooked beak it
differs widely from that bird. The name of Sociable Marsh-Hawk, which
Azara gave to this species, is very appropriate, for they invariably
live in flocks of from twenty to a hundred individuals, and migrate
and even breed in company. In Buenos Ayres they appear in September
and resort to marshes and streams abounding in large water-snails
(_Ampullaria_), on which they feed exclusively. Each bird has a
favourite perch or spot of ground to which it carries every snail it
captures, and after skilfully extracting the animal with its curiously
modified beak, it drops the shell on the mound. When disturbed or
persecuted by other birds they utter a peculiar cry, resembling the
shrill neighing of a horse. In disposition they are most peaceable, and
where they are abundant all other birds soon discover that they are not
as other Hawks are and pay no attention to them. When soaring, which
is their favourite pastime, the flight is singularly slow, the bird
frequently remaining motionless for long intervals in one place; but the
expanded tail is all the time twisted about in the most singular manner,
moved from side to side, and turned up until its edge is nearly at a
right angle with the plane of the body. These tail-movements appear to
enable it to remain stationary in the air without the rapid vibratory
wing-motions practised by _Elanus leucurus_ and other hovering birds;
and I should think that the vertebræ of the tail must have been somewhat
modified by such a habit.

Concerning its breeding-habits Mr. Gibson writes:--"In the year 1873 I
was so fortunate as to find a breeding colony in one of our largest and
deepest swamps. There were probably twenty or thirty nests, placed a few
yards apart, in the deepest and most lonely part of the whole 'cañadon.'
They were slightly built platforms, supported on the rushes and two or
three feet above the water, with the cup-shaped hollow lined with pieces
of grass and water-rush. The eggs never exceeded three in a nest;
the ground-colour generally bluish white, blotched and clouded very
irregularly with dull red-brown, the rufous tint sometimes being
replaced with ash-grey."

    _Description._--Above brown, with black shaft-stripes; head black,

    nape, forming an ill-defined nuchal band; rump pure white; wings
    black, with white oval spots on the outer and white bars on the
    inner webs; tail black, all the lateral rectrices crossed by five or
    six broad white bars: beneath white, breast regularly striped with
    narrow black shaft stripes; bill plumbeous, lower mandible yellow,
    except at the tip; feet greenish, nails black: whole length 11
    inches, wing 6·5, tail 5·0. _Female_ similar, but rather larger.

_Hab._ Argentina.

This small Hawk is sometimes met with in the woods of La Plata, near the
river; it is rare, but owing to its curious violent flight, with the
short blunt wings rapidly beating all the time, it is very conspicuous
in the air and well known to the natives, who call it _Rey de los
Pajaros_ (King of the Birds), and entertain a very high opinion of its
courage and strength. I have never seen it taking its prey, and do not
believe that it ever attempts to capture anything in the air, its short
blunt wings and peculiar manner of flight being unsuited for such a
purpose. Probably it captures birds by a sudden dash when they mob it on
its perch; and I do not know any raptor more persistently run after and
mobbed by small birds. I once watched one for upwards of an hour as it
sat on a tree attended by a large flock of Guira Cuckoos, all excitedly
screaming and bent on dislodging it from its position. So long as they
kept away five or six feet from it the Hawk remained motionless, only
hissing and snapping occasionally as a warning; but whenever a Cuckoo
ventured a little nearer and into the charmed circle, it would make a
sudden rapid dash and buffet the intruder violently back to a proper
distance, returning afterwards to its own stand.

_Hab._ Southern half of South America.

Azara says of the Carancho (_Polyborus tharus_):--"All methods of
subsistence are known to this bird: it pries into, understands, and
takes advantage of everything." These words apply better to the
Chimango, which has probably the largest bill of fare of any bird, and
has grafted on to its own peculiar manner of life the habits of twenty
diverse species. By turns it is a falcon, a vulture, an insect-eater,
and a vegetable-eater. On the same day you will see one bird in violent
hawk-like pursuit of its living prey, with all the instincts of rapine
hot within it, and another less ambitious individual engaged in
laboriously tearing at an old cast-off shoe, uttering mournful notes the
while, but probably more concerned at the tenacity of the material than
at its indigestibility.

A species so cosmopolitan in its tastes might have had a whole volume to
itself in England; being only a poor foreigner, it has had no more than
a few unfriendly paragraphs bestowed upon it. For it happens to be a
member of that South-American subfamily of which even grave naturalists
have spoken slightingly, calling them vile, cowardly, contemptible
birds; and the Chimango is nearly least of them all--a sort of poor
relation and hanger on of a family already looked upon as bankrupt
and disreputable. Despite this evil reputation, few species are more
deserving of careful study; for throughout an extensive portion of South
America it is the commonest bird we know; and when we consider how
closely connected are the lives of all living creatures by means of
their interlacing relations, so that the predominance of any one kind,
however innocuous, necessarily causes the modification, or extinction
even, of surrounding species, we are better able to appreciate the
importance of this despised fowl in the natural polity. Add to this its
protean habits, and then, however poor a creature our bird may seem, and
deserving of strange-sounding epithets from an ethical point of view, I
do not know where the naturalist will find a more interesting one.

The Chimango has not an engaging appearance. In size and figure it much
resembles the Hen-harrier, and the plumage is uniformly of a light sandy
brown colour; the shanks are slender, claws weak, and beak so slightly
hooked that it seems like the merest apology of the Falcon's tearing
weapon. It has an easy loitering flight, and when on the wing does not
appear to have an object in view, like the Hawk, but wanders and prowls
about here and there, and when it spies another bird it flies after him
to see if he has food in his eye. When one finds something to eat the
others try to deprive him of it, pursuing him with great determination
all over the place; if the foremost pursuer flags, a fresh bird takes
its place, until the object of so much contention--perhaps after all
only a bit of skin or bone--is dropped to the ground, to be instantly
snatched up by some bird in the tail of the chase; and he in turn
becomes the pursued of all the others. This continues till one grows
tired and leaves off watching them without seeing the result. They are
loquacious and sociable, frequently congregating in loose companies of
thirty or forty individuals, when they spend several hours every day
in spirited exercises, soaring about like Martins, performing endless
evolutions, and joining in aerial mock battles. When tired of these
pastimes they all settle down again, to remain for an hour or so perched
on the topmost boughs of trees or other elevations; and at intervals
one bird utters a very long leisurely chant, with a falling inflection,
followed by a series of short notes, all the other birds joining in
chorus and uttering short notes in time with those of their soloist or
precentor. The nest is built on trees or rushes in swamps, or on the
ground amongst grass and thistles. The eggs are three or four in number,
nearly spherical, blotched with deep red on a white or creamy ground;
sometimes the whole egg is marbled with red; but there are endless
varieties. It is easy to find the nest, and becomes easier when there
are young birds, for the parent when out foraging invariably returns to
her young uttering long mournful notes, so that one has only to listen
and mark the spot where it alights. After visiting a nest I have always
found the young birds soon disappear, and as the old birds vanish also
I believe that the Chimango removes its young when the nest has been
discovered--a rare habit with birds.

Chimangos abound most in settled districts, but a prospect of food will
quickly bring numbers together even in the most solitary places. On the
desert pampas, where hunters, Indian and European, have a great fancy
for burning the dead grass, the moment the smoke of a distant fire is
seen there the Chimangos fly to follow the conflagration. They are,
at such times, strangely animated, dashing through clouds of smoke,
feasting amongst the hot ashes on roasted cavies and other small
mammals, and boldly pursuing the scorched fugitives from the flames.

At all times and in all places the Chimango is ever ready to pounce on
the weak, the sickly, and the wounded. In other regions of the globe
these doomed ones fall into the clutches of the true bird of prey; but
the salutary office of executioner is so effectually performed by the
Chimango and his congeners where these false Hawks abound, that the true
Hawks have a much keener struggle to exist here. This circumstance has
possibly served to make them swifter of wing, keener of sight, and
bolder in attack than elsewhere. I have seen a Buzzard, which is not
considered the bravest of the Hawks, turn quick as lightning on a
Cayenne Lapwing, which was pursuing it, and grappling it bear it down to
the ground and despatch it in a moment, though a hundred other Lapwings
were uttering piercing screams above it. Yet this Plover is a large,
powerful, fierce-tempered bird, and armed with sharp spurs on its wings.
This is but one of numberless instances I have witnessed of the extreme
strength and daring of our Hawks.

When shooting birds to preserve I used to keep an anxious eye on the
movements of the Chimangos flying about, for I have had some fine
specimens carried off or mutilated by these omnipresent robbers. One
winter day I came across a fine _Myiotheretes rufiventris_, a pretty
and graceful Tyrant-bird, rather larger than the Common Thrush, with
a chocolate and silver-grey plumage. It was rare in that place, and,
anxious to secure it, I fired a very long shot, for it was extremely
shy. It rose up high in the air and flew off apparently unconcerned.
What, then, was my surprise to see a Chimango start off in pursuit of
it! Springing on to my horse, I followed, and before going half a mile
noticed the Tyrant-bird beginning to show signs of distress. After
avoiding several blows aimed by the Chimango, it flew down and plunged
into a cardoon bush. There I captured it, and when skinning it to
preserve found that one small shot had lodged in the fleshy portion
of the breast. It was a very slight wound, yet the Chimango with its
trained sight had noticed something wrong with the bird from the moment
it flew off, apparently in its usual free buoyant manner.

On another occasion I was defrauded of a more valuable specimen than the
Tyrant-bird. It was on the east coast of Patagonia, when one morning,
while seated on an elevation, watching the waves dashing themselves on
the shore, I perceived a shining white object tossing about at some
distance from land. Successive waves brought it nearer, till at last
it was caught up and flung far out on to the shingle, fifty yards from
where I sat; and instantly, before the cloud of spray had vanished,
a Chimango dashed down upon it. I jumped up and ran down as fast as I
could, and found my white object to be a Penguin, apparently just killed
by some accident out at sea, and in splendid plumage; but, alas! in that
moment the vile Chimango had stripped off and devoured the skin from its
head, so that as a specimen it was hopelessly ruined.

As a rule, strong healthy birds despise the Chimango; they feed in his
company; his sudden appearance causes no alarm, and they do not take
the trouble to persecute him; but when they have eggs or young he is
not to be trusted. He is not easily turned from a nest he has once
discovered. I have seen him carry off a young Tyrant-bird (_Milvulus
tyrannus_), in the face of such an attack from the parent birds that
one would have imagined not even an Eagle could have weathered such a
tempest. Curiously enough, like one of the boldest of our small Hawks
(_Tinnunculus cinnamominus_), they sometimes attack birds so much too
strong and big for them that they must know the assault will produce
more annoyance than harm. I was once watching a flock of Coots feeding
on a grassy bank, when a passing Chimango paused in its flight, and,
after hovering over them a few moments, dashed down upon them with such
impetuosity that several birds were thrown to the ground by the quick
successive blows of its wings. There they lay on their backs, kicking,
apparently too much terrified to get up, while the Chimango deliberately
eyed them for some moments, then quietly flew away, leaving them to dash
into the water and cool their fright. Attacks like these are possibly
made in a sportive spirit, for the Milvago is a playful bird, and, as
with many other species, bird and mammal, its play always takes the form
of attack.

Its inefficient weapons compel it to be more timid than the Hawk, but
there are many exceptions, and in every locality individual birds are
found distinguished by their temerity. Almost any shepherd can say
that his flock is subject to the persecutions of at least one pair of
lamb-killing birds of this species. They prowl about the flock, and
watch till a small lamb is found sleeping at some distance from its dam,
rush upon it, and, clinging to its head, eat away its nose and tongue.
The shepherd is then obliged to kill the lamb; but I have seen many
lambs that have been permitted to survive the mutilation, and which have
grown to strong, healthy sheep, though with greatly disfigured faces.
One more instance I will give of the boldness of a bird of which Azara,
greatly mistaken, says that it might possibly have courage enough to
attack a mouse, though he doubts it. Close to my house, when I was a
boy, a pair of these birds had their nest near a narrow path leading
through a thicket of giant thistles, and every time I traversed this
path the male bird, which, contrary to the rule with birds of prey,
is larger and bolder than the female, would rise high above me, then
dashing down, strike my horse a violent blow on the forehead with
its wings. This action it would repeat till I was out of the path.
I thought it very strange the bird never struck _my_ head; but I
presently discovered that it had an excellent reason for what it
did. The gauchos ride by preference on horses never properly tamed,
and one neighbour informed me that he was obliged every day to make
a circuit of half a mile round the thistles, as the horses he rode
became quite unmanageable in the path, they had been so terrified
with the attacks of this Chimango.

Where the intelligence of the bird appears to be really at fault is in
its habit of attacking a sore-backed horse, tempted thereto by the sight
of a raw spot, and apparently not understanding that the flesh it wishes
to devour is an inseparable part of the whole animal. Darwin has noticed
this curious blunder of the bird; and I have often seen a chafed
saddle-horse wildly scouring the plain closely pursued by a hungry
Chimango determined to dine on a portion of him.

In the hot season, when marshes and lagoons are drying up, the Chimango
is seen associating with Ibises and other waders, standing knee-deep in
the water and watching for tadpoles, frogs, and other aquatic prey. He
also wades after a very different kind of food. At the bottom of pools,
collected on clayey soil after a summer shower, an edible fungus grows
of a dull greenish colour and resembling gelatine. He has found out that
this fungus is good for food, though I never saw any other creature
eating it. In cultivated districts he follows the plough in company with
the black-headed gulls, Molothri, Guira cuckoos, and tyrant-birds, and
clumsily gleans amongst the fresh-turned mould for worms and larvæ. He
also attends the pigs when they are rooting on the plain to share any
succulent treasure-trove turned up by their snouts; for he is not a bird
that allows dignity to stand between him and his dinner. In the autumn,
on damp, sultry days, the red ants, that make small conical mounds on
the pampas, are everywhere seen swarming. Rising high in the air they
form a little cloud or column, and hang suspended for hours over the
same spot. On such days the Milvagos fare sumptuously on little insects,
and under each cloud of winged ants several of them are to be seen in
company with a few Flycatchers, or other diminutive species, briskly
running about to pick up the falling manna, their enjoyment undisturbed
by any sense of incongruity.

Before everything, however, the Chimango is a vulture, and is to be
found at every solitary rancho sharing with dogs and poultry the offal
and waste meat thrown out on the dust-heap; or, after the flock has
gone to pasture, tearing at the eyes and tongue of a dead lamb in the
sheepfold. When the hide has been stripped from a dead horse or cow on
the plains, the Chimango is always first on the scene. While feeding
on a carcass it incessantly utters a soliloquy of the most lamentable
notes, as if protesting against the hard necessity of having to put up
with such carrion fare--long, querulous cries, resembling the piteous
whines of a shivering puppy chained up in a bleak backyard and all its
wants neglected, but infinitely more doleful in character. The gauchos
have a saying comparing a man who grumbles at good fortune to the
Chimango crying on a carcass; an extremely expressive saying to those
who have listened to the distressful wailings of the bird over its meat.
In winter a carcass attracts a great concourse of the Black-backed
Gulls; for with the cold weather these vultures of the sea abandon their
breeding-places on the Atlantic shores to wander in search of food over
the vast inland pampas. The dead beast is quickly surrounded by a host
of them, and the poor Chimango crowded out. One at least, however, is
usually to be seen perched on the carcass tearing at the flesh, and
at intervals with outstretched neck and ruffled up plumage uttering
a succession of its strange wailing cries, reminding one of a public
orator mounted on a rostrum and addressing harrowing appeals to a crowd
of attentive listeners. When the carcass has been finally abandoned
by foxes, armadillos, gulls, and caracaras, the Chimango still clings
sorrowfully to it, eking out a miserable existence by tearing at a
fringe of gristle and whetting his hungry beak on the bones.

Though an inordinate lover of carrion, a wise instinct has taught it
that this aliment is unsuited to the tender stomachs of its fledglings;
these it feeds almost exclusively on the young of small birds. In
November the Chimangos are seen incessantly beating over the cardoon
bushes, after the manner of Hen-harriers; for at this season in the
cardoons breeds the _Synallaxis hudsoni_. This bird, sometimes called
_Téru-réru del campo_ by the natives, is excessively shy and mouse-like
in its habits, seldom showing itself, and by means of strong legs and
a long, slender, wedge-like body is able too glide swiftly as a snake
through and under the grass. In summer one hears its long melancholy
trilling call-note from a cardoon bush, but if approached it drops to
the ground and vanishes. Under the densest part of the cardoon bush it
scoops out a little circular hollow in the soil, and constructs over it
a dome of woven grass and thorns, leaving only a very small aperture: it
lines the floor with dry horse-dung, and lays five buff-coloured eggs.
So admirably is the nest concealed that I have searched every day for
it through a whole breeding-season without being rewarded with a single
find. Yet they are easily found by the Chimango. In the course of a
single day I have examined five or six broods of young Chimangos, and
by pressing a finger in their distended crops, made them disgorge their
food, and found in every instance that they had been fed on nothing but
the young of the _Téru-réru_. I was simply amazed at this wholesale
destruction of the young of a species so secret in its nesting-habits;
for no eye, even of a Hawk, can pierce through the leafage of a cardoon
bush, ending near the surface in an accumulated mass of the dead and
decaying portions of the plant. The explanation of the Chimango's
success is to be found in the loquacious habit of the fledglings it
preys on, a habit common in the young of Dendrocolaptine species. The
intervals between the visits of the parent birds with food they spend in
conversing together in their high-pitched tones. If a person approaches
the solid fabric of the Ovenbird (_Furnarius rufus_), when there
are young in it, he will hear shrill laughter-like notes and little
choruses, like those uttered by the old birds, only feebler; but in the
case of that species no harm can result from the loquacity of the
young, since the castle they inhabit is impregnable. Hovering over
the cardoons, the Chimango listens for the stridulous laughter of the
fledglings, and when he hears it the thorny covering is quickly pierced
and the dome broken into.

Facts like this bring before us with startling vividness the struggle
for existence, showing what great issues in the life of a species may
depend on matters so trivial, seemingly, that to the uninformed mind
they appear like the merest dust in the balance, which is not regarded.
And how tremendous and pitiless is that searching law of the survival
of the fittest in its operations when we see a species like this
_Synallaxis_, in the fashioning and perfecting of which nature seems
to have exhausted all her art, so exquisitely is it adapted in
its structure, coloration, and habits to the one great object of
concealment, yet apparently doomed to destruction through this one petty
oversight--the irrepressible garrulity of the fledglings in their nest!
It is, however, no oversight at all; since the law of natural selection
is not prophetic in its action, and only preserves such variations as
are beneficial in existing circumstances, without anticipating changes
in the conditions. The settlement of the country has, no doubt, caused
a great increase of Chimangos, and in some indirect way probably has
served to quicken their intelligence; thus a change in the conditions
which have moulded this _Synallaxis_ brings a danger to it from an
unexpected quarter. The situation of the nest exposes it, one would
imagine, to attacks from snakes and small mammals, from bird-killing
spiders, beetles, and crickets, yet these subtle ground foes have missed
it, while the baby-laughter of the little ones in their cradle has
called down an unlooked-for destroyer from above. It might be answered
that this must be a very numerous species, otherwise the Chimango could
not have acquired the habit of finding the nests; that when they become
rarer the pursuit will be given over, after which the balance will
readjust itself. But in numbers there is safety, especially for a feeble
hunted species, unable from its peculiar structure to vary its manner of
life. To such, the remark made by Darwin, that "rarity is the precursor
to extinction," applies with peculiar force.

This bird, which combines the raptorial instincts of the Eagle with the
base carrion-feeding propensities of the Vulture, has already had so
many biographers that it might seem superfluous to speak again at any
great length of it; only it happens to be one of those very versatile
species about which there is always something fresh to be said; and,
besides, I do not altogether agree with the very ignoble character
usually ascribed to it by travellers. It is, however, probable that it
varies greatly in disposition and habits in different districts. In
Patagonia I was surprised at its dejected appearance and skulking
cowardly manner, so unlike the bird I had been accustomed to see on the
pampas. I shot several, and they were all in a miserably poor condition
and apparently half-starved. It struck me that in that cold sterile
country, where prey is scarce, the Carancho is altogether out of place;
for it there has to compete with Eagles and Vultures in large numbers;
and these, it is almost needless to say, are, in their separate lines,
stronger than the composite and less specialized Carancho. In Patagonia
he is truly a "miserable bird," with a very frail hold on existence. How
different on that illimitable grassy ocean further north, where he is
the lord of the feathered race, for Eagles and Vultures, that require
mountains and trees to breed and roost on, do not come there to set him
aside; there the conditions are suited to him and have served to develop
in him a wonderfully bold and savage spirit. When seen perched on a
conical ant-hill, standing erect above the tall plumy grass, he has a
fine, even a noble, appearance; but when flying he is not handsome, the
wings being very bluntly rounded at the extremities and the flight low
and ungraceful. The plumage is blackish in the adult, brown in the
young. The sides of the head and breast are creamy white, the latter
transversely marked with black spots. The crown is adorned with a crest
or top-knot. The beak is much larger than in Eagles and Vultures, and of
a dull blue colour; the cere and legs are bright yellow.

The species ranges throughout South America, and from Paraguay
northwards is called everywhere, I believe, "Caracara." South of Paraguay
the Spanish name is "Carancho," possibly a corruption of "Keanché," the
Puelche name for the allied _Milvago chimango_, in imitation of its
peevish cry. The Indian name for the Carancho in these regions is
_Trarú_ (from its harsh cry), misspelt _tharú_ by Molina.

The Caranchos pair for life, and may therefore be called social birds;
they also often live and hunt in families of the parent and young birds
until the following spring; and at all times several individuals will
readily combine to attack their prey, but they never live or move about
in flocks. Each couple has its own home or resting-place, which they
will continue to use for an indefinite time, roosting on the same branch
and occupying the same nest year after year; while at all times the two
birds are seen constantly together and seem very much attached. Azara
relates that he once saw a male pounce down on a frog, and carrying it
to a tree call his mate to him and make her a present of it. It was not
a very magnificent present, but the action seems to show that the bird
possesses some commendable qualities which are seldom seen in the
raptorial family.

In uninhabited places I have always found the Caranchos just as abundant
as in the settled districts; and after a deer has been pulled down by
the dogs I have seen as many as seventy or eighty birds congregate
to feed on its flesh within half an hour, although not one had been
previously visible. D'Orbigny describes the bird as a parasite on man,
savage and civilized, following him everywhere to feed on the leavings
when he slays wild or domestic animals, and as being scarcely able to
exist without him. No doubt the bird does follow man greatly to its
advantage, but this is only in very thinly settled and purely pastoral
and hunting districts, where a large proportion of the flesh of every
animal slain is given to the fowls of the air. Where the population
increases the Carancho quickly meets with the fate of all large species
which are regarded as prejudicial.

Without doubt it is a carrion-eater, but only, I believe, when it cannot
get fresh provisions; for when famished it will eat anything rather
than study its dignity and suffer hunger like the nobler Eagle. I have
frequently seen one or two or three of them together on the ground under
a column of winged ants, eagerly feasting on the falling insects. To eat
putrid meat it must be very hungry indeed; it is, however, amazingly
fond of freshly-killed flesh, and when a cow is slaughtered at an
estancia-house the Carancho quickly appears on the scene to claim his
share, and catching up the first thing he can lift he carries it off
before the dogs can deprive him of it. When he has risen to a height
of five or six yards in the air he drops the meat from his beak and
dexterously catches it in his claws without pausing or swerving in his
flight. It is singular that the bird seems quite incapable of lifting
anything from the ground with the claws, the beak being invariably used,
even when the prey is an animal which it might seem dangerous to lift
in this way. I once saw one of these birds swoop down on a rat from a
distance of about forty feet, and rise with its struggling and squealing
prey to a height of twenty feet, then drop it from its beak and
gracefully catch it in its talons. Yet when it pursues and overtakes a
bird in the air it invariably uses the claws in the same way as other
Hawks. This I have frequently observed, and I give the two following
anecdotes to show that even birds which one would imagine to be quite
safe from the Carancho are on some occasions attacked by it.

While walking in a waste field near my home one day I came on a Pigeon
feeding, and at once recognized it as one which had only began to fly
about a week before; for although a large number of Pigeons were kept,
this bird happened to be of the purest unspotted white, and for a long
time I had been endeavouring to preserve and increase the pure
white individuals, but with very little success, for the Peregrines
invariably singled them out for attack. A Carancho was circling about at
some distance overhead, and while I stood still to watch and admire my
Pigeon it stooped to within twenty yards of the surface and remained
hovering over my head. Presently the Pigeon became alarmed and flew
away, whereupon the Hawk gave chase--a very vain chase I imagined it
would prove. It lasted for about half a minute, the Pigeon rushing
wildly round in wide circles, now mounting aloft and now plunging
downwards close to the surface, the Carancho hotly following all the
time. At length, evidently in great terror, the hunted bird flew down,
alighting within a yard and a half of my feet. I stooped to take hold of
it, when, becoming frightened at my action, it flew straight up and was
seized in the talons of its pursuer close to my face and carried away.

In the next case the bird attacked was the Spur-winged Lapwing, the
irreconcilable enemy of the Carancho and its bold and persistent
persecutor. The very sight of this Hawk rouses the Lapwings to a frenzy
of excitement, and springing aloft they hasten to meet it in mid-air
screaming loudly, and continue to harry it until it leaves their
ground, after which they return, and, ranged in triplets, perform their
triumphal dances, accompanied with loud drumming notes. But if their
hated foe alights on the ground, or on some elevation near them, they
hover about him, and first one, then another, rushes down with the
greatest violence, and gliding near him turns the bend of its wing
so that the spur appears almost to graze his head. While one bird is
descending, others are rising upwards to renew their charges; and this
persecution continues until they drive him away, or become exhausted
with their fruitless efforts. The Carancho, however, takes little notice
of his tormentors; only when the Plover comes very close, evidently bent
on piercing his skull with its sharp weapon, he quickly dodges his head,
after which he resumes his indifferent demeanour until the rush of the
succeeding bird takes place.

While out riding one day a Carancho flew past me attended by about
thirty Lapwings, combined to hunt him from their ground, for it was
near the breeding-season, when their jealous irascible temper is most
excited. All at once, just as a Lapwing swept close by and then passed
on before it, the Hawk quickened its flight in the most wonderful manner
and was seen in hot pursuit of its tormentor. The angry hectoring cries
of the Lapwings instantly changed to piercing screams of terror, which
in a very short time brought a crowd numbering between two and three
hundred birds to the rescue. Now, I thought, the hunted bird will
escape, for it twisted and turned rapidly about, trying to lose itself
amongst its fellows, all hovering in a compact cloud about it and
screaming their loudest. But the Carancho was not to be shaken off; he
was never more than a yard behind his quarry, and I was near enough to
distinguish the piteous screams of the chased Lapwing amidst all the
tumult, as of a bird already captive. At the end of about a minute it
was seized in the Carancho's talons, and, still violently screaming,
borne away. The cloud of Lapwings followed for some distance, but
presently they all returned to the fatal spot where the contest had
taken place; and for an hour afterwards they continued soaring about in
separate bodies, screaming all the time with an unusual note in their
voices as of fear or grief, and holding excited conclaves on the ground,
too all appearance as greatly disturbed in their minds as an equal
number of highly emotional human beings would be in the event of a
similar disaster overtaking them.

It is not often, however, that the Carancho ventures singly to attack
adult and vigorous birds, except Tinamous; they prey by preference on
the young or ailing, on small lambs and pigs left at a distance by their
dams; and they also frequently attack and kill old and weakly sheep.
Where anything is wrong with bird or beast they are very quick to
detect it, and will follow a sportsman to pick up the wounded birds,
intelligently keeping at a safe distance themselves. I once shot a
Flamingo in the grey stage of plumage and had some trouble to cross the
stream, on the opposite side of which the bird, wounded very slightly,
was rapidly stalking away. In three or four minutes I was over and found
my Flamingo endeavouring to defend itself against the assaults of a
Carancho which had marked it for its own, and was striking it on the
neck and breast in the most vigorous and determined way, sometimes from
above, at other times alighting on the ground before it and springing
up to strike like a game-cock. A spot of blood on the plumage of the
wounded bird, which had only one wing slightly damaged, had been
sufficient to call down the attack; for to the Carancho a spot of blood,
a drooping wing, or any irregularity in the gait, quickly tells its

When several of these birds combine they are very bold. A friend told me
that while voyaging on the Paraná river a Black-necked Swan flew past
him hotly pursued by three Caranchos; and I also witnessed an attack by
four birds on a widely different species. I was standing on the bank of
a stream on the pampas watching a great concourse of birds of several
kinds on the opposite shore, where the carcass of a horse, from which
the hide had been stripped, lay at the edge of the water. One or two
hundred Hooded Gulls and about a dozen Chimangos were gathered about
the carcass, and close to them a very large flock of Glossy Ibises were
wading about in the water, while amongst these, standing motionless
in the water, was one solitary White Egret. Presently four Caranchos
appeared, two adults and two young birds in brown plumage, and alighted
on the ground near the carcass. The young birds advanced at once and
began tearing at the flesh; while the two old birds stayed where they
had alighted, as if disinclined to feed on half-putrid meat. Presently
one of them sprung into the air and made a dash at the birds in the
water, and instantly all the birds in the place rose into the air
screaming loudly, the two young brown Caranchos only remaining on the
ground. For a few moments I was in ignorance of the meaning of all this
turmoil, when, suddenly, out of the confused black and white cloud of
birds the Egret appeared, mounting vertically upwards with vigorous
measured strokes. A moment later and first one, then the other, Carancho
also emerged from the cloud, evidently pursuing the Egret, and only then
the two brown birds sprung into the air and joined in the chase. For
some minutes I watched the four birds toiling upwards with a wild zigzag
flight, while the Egret, still rising vertically, seemed to leave them
hopelessly far behind. But before long they reached and passed it, and
each bird as he did so would turn and rush downwards, striking at the
Egret with his claws, and while one descended the others were rising,
bird following bird with the greatest regularity. In this way they
continued toiling upwards until the Egret appeared a mere white speck in
the sky, about which the four hateful black spots were still revolving.
I had watched them from the first with the greatest excitement, and now
began to fear that they would pass from sight and leave me in ignorance
of the result; but at length they began to descend, and then it looked
as if the Egret had lost all hope, for it was dropping very rapidly,
while the four birds were all close to it striking at it every three
or four seconds. The descent for the last half of the distance was
exceedingly rapid, and the birds would have come down almost at the very
spot they started from, which was about forty yards from where I stood,
but the Egret was driven aside, and sloping rapidly down struck the
earth at a distance of two hundred and fifty yards from the starting
point. Scarcely had it touched the ground before the hungry quartette
were tearing it with their beaks. They were all equally hungry no doubt,
and perhaps the old birds were even hungrier than their young; and I
am quite sure that if the flesh of the dead horse had not been so far
advanced towards putrefaction they would not have attempted the conquest
of the Egret.

I have so frequently seen a pure white bird singled out for attack in
this way, that it has always been a great subject of wonder to me how
the two common species of snow-white Herons in South America are able
to maintain their existence; for their whiteness exceeds that of other
white Waterfowl, while, compared with Swans, Storks, and the Wood-Ibis,
they are small and feeble. I am sure that if these four Caranchos had
attacked a Glossy Ibis they would have found it an easier conquest; yet
they singled out the Egret, purely, I believe, on account of its shining
white conspicuous plumage.

This wing-contest was a very splendid spectacle, and I was very glad
that I had witnessed it, although it ended badly for the poor Egret; but
in another case of a combined attack by Caranchos there was nothing to
admire except the intelligence displayed by the birds in combining,
and much to cause the mind to revolt against the blindly destructive
ferocity exhibited by Nature in the instincts of her creatures. This
scene was witnessed by a beloved old Gaucho friend of mine, a born
naturalist, who related it to me. It was in summer, and he was riding in
a narrow bridle-path on a plain covered with a dense growth of giant
thistles, nine or ten feet high, when he noticed some distance ahead
several Caranchos hovering over one spot; and at once conjectured that
some large animal had fallen there, or that a traveller had been thrown
from his horse and was lying injured amongst the thistles. On reaching
the spot, he found an open space of ground about forty yards in
diameter, surrounded by the dense wall of close-growing thistles,
and over this place the birds were flying, while several others were
stationed near, apparently waiting for something to happen. The
attraction was a large male Rhea squatting on the ground, and sheltering
with its extended wings a brood of young birds. My friend was not able
to count them, but there were not fewer than twenty-five or thirty young
birds, small tender things, only a day or so out of the shell. As soon
as he rode into the open space of ground, the old Ostrich sprung up,
and  with lowered head, clattering beak, and broad wings spread out like
sails, rushed at him; his horse was greatly terrified, and tried to
plunge into the dense mass of thistles, so that he had the greatest
difficulty in keeping his seat. Presently the Ostrich left him, and
casting his eyes round he was astonished to see that all the young
Ostriches were running about, scattered over the ground, while the
Caranchos were pursuing, knocking down, and killing them. Meanwhile the
old Ostrich was frantically rushing about trying to save them; but the
Caranchos, when driven from one bird they were attacking, would merely
rise a few yards and drop on the next one a dozen yards off; and as
there were about fifteen Caranchos all engaged in the same way, the
slaughter was proceeding at a great rate. My friend, who had been vainly
struggling to get the better of his horse, was then forced to leave the
place, and did not therefore see the end of the tragedy in which he had
acted an involuntary part; but before going he saw that at least half
the young birds were dead, and that these were all torn and bleeding on
the small of the neck just behind the head, while in some cases the head
had been completely wrenched off.

The Gauchos, when snaring Partridges (Tinamous), frequently bribe the
Caranchos to assist them. The snarer has a long slender cane with a
small noose at the extremity, and when he sights a Partridge he gallops
round it in circles until the bird crouches close in the grass; then the
circles are narrowed and the pace slackened, while he extends the cane,
and lowers it gradually over the bewildered bird until the small noose
is dropped over its head and it is caught. Many Partridges are not
disposed to sit still to be taken in this open barefaced way; but if the
snarer keeps a Carancho hovering about by throwing him an occasional
gizzard, the wariest Partridge is so stricken with fear that it will sit
still and allow itself to be caught.

In the love-season the male Caranchos are frequently seen fighting; and
sometimes, when the battle is carried on at a great height in the air,
the combatants are seen clasped together and falling swiftly towards the
earth; but in all the contests I have witnessed the birds have not been
so blinded with passion as to fall the whole distance before separating.
Besides these single combats, in which unpaired or jealous males engage
in the love-season, there are at all times occasional dissensions
amongst them, the cause of which it would be difficult to determine.
Here again, as often in hunting, the birds combine to punish an
offender, and in some cases the punishment is death.

Their cry is exceedingly loud and harsh, a short abrupt note, like
_cruk_, repeated twice; after which, if the bird is violently agitated,
as when wounded or fighting, it throws its head backwards until the
crown rests on the back, and rocks it from side to side, accompanying
the action with a prolonged piercing cry of great power. This singular
gesture of the Carancho, unique among birds, seems to express very
forcibly a raging spirit, or, perhaps, rage mingled with despair.

The nest is built in a variety of situations: on trees, where there are
any, but on the treeless pampas, where the Carancho is most at home,
it is made on the ground, sometimes among the tall grass, while a very
favourite site is a small islet or mound of earth rising well out of the
water. When a suitable place has been found, the birds will continue
to use the same nest for many consecutive years. It is a very large
slovenly structure of sticks, mixed with bones, pieces of skin, dry
dung, and any portable object the bird may find to increase the bulk
of his dwelling. The eggs are three or four, usually the last number,
slightly oval, and varying greatly in colour and markings, some having
irregular dark red blotches on a cream-coloured ground, while others are
entirely of a deep brownish red, with a few black marks and blotches.


The American Vultures, or Condors as it is better to call them, are
now universally admitted to be quite distinct from the rest of the
Accipitres and to constitute a family apart. They differ from the
Falconidæ in having the hind toe inserted at a higher level than the
others, and in the nostrils being pervious, owing to the absence of the
bony septum, besides in other important characters[2].

  [2] _Cf._ Standard Nat. Hist. vol. iv., Birds, p. 266 (Boston, 1885).

The Cathartidæ are few in number, only some six or seven species being
accurately known. Of these, three occur within the limits of the
Argentine Republic.

Falkland Islands.

In Argentina the Turkey-Vulture appears only to occur in the northern
and western provinces. Dr. Burmeister noticed it occasionally in
Mendoza, Catamarca, and Tucuman. In Misiones, White found it abundant
at Concepcion. I met with it in Patagonia, but it is by no means common
there, and is only seen singly or in pairs.

_Hab._ Eastern U.S., and Central and Southern America to Chili and the

According to Dr. Burmeister the Black Vulture is found throughout the
Argentine Pampas, but is commoner in the east and north. It is known as
the "_Gallinazo_" at Mendoza, and "_Cuervo_" in Tucuman. Mr. Barrows
tells us that he did not see it during his residence at Concepcion, but
was told of its former abundance in times of drought, when dead sheep
were numerous. It was, however, met with by him in small numbers during
his excursion through the Sierras of the Pampas south of Buenos Ayres.

On the Rio Negro of Patagonia I found these Vultures abundant,
especially near the settlement of El Carmen, where, attracted by the
refuse of the cattle-slaughtering establishments, they congregated in
immense numbers, and were sometimes seen crowded together in thousands
on the trees, where they roosted. Darwin observed them at the same
place, and has described their soaring habits at considerable length.

The following account of the nesting-habits of this species is given by
Mr. John J. Dalgleish (Proc. Roy. Phys. Soc. Edinb. vi. p. 237):--"The
eggs seldom, if ever, exceed two in number, and are usually laid in a
hollow tree or on the ground. Their average weight is about a pound.
They are slightly larger than those of the Turkey-Buzzard, although the
latter is a bigger bird. The ground-colour is of a yellowish white, with
blotches of dark reddish brown, and smaller markings of a lilac shade.
These markings are generally more numerous at the larger end."

    _Description._--General plumage glossy black; greater wing-coverts
    margined with ashy; neck-ruff white; head, neck, and centre of chest
    bare; head, with a large caruncle, black; throat wattled; chest with
    a pendent wattle: whole length 38·0 inches, wing 29·0, tail 14·0.
    _Female_ similar, but without the wattles on the head and neck.

_Hab._ Andes of South America, and adjacent ranges in La Plata.

Dr. Burmeister tells us that he has seen the Condor in the Sierras of
Cordova and Aconquija, though it is more prevalent in the districts of
the Western Cordillera.

In the territory of Chupat, Durnford met with it at Ninfas Point
in November, and tells us that when the colonists are hunting in
the neighbourhood of the sea-coast the Condor is the first of the
bird-scavengers to make its appearance after game has been killed.

During his subsequent excursion to the Sengel river in the interior, the
Condor was commonly observed throughout the journey wherever the rocks
were high and steep. Several pairs were noticed nesting on Nov. 16th,
but the nests could not be reached.

My own experience of the Condor is restricted in seeing one individual,
flying above the sea-shore, south of the Rio Negro.



The only family of the Steganopodes that can at present be inserted in
the Argentine list is that of the Cormorants, though doubtless other
forms of this Order (_Sula_, _Phaethon_, and _Fregata_) will be
hereafter found to occur on the coast with more or less frequency.

One Cormorant only has yet been positively determined as occurring
within the Argentina area.

    neck greyish, with the tips of the feathers black; breast white,
    with blackish-brown mottlings; belly black.

_Hab._ Sea-coasts and inland waters of Central and South America.

This appears to be the only Cormorant met with on the coasts and inland
waters of South America north of Buenos Ayres; but two other species are
found in Southern Chili and Patagonia, which may probably likewise occur
in the southern provinces of the Republic[3].

  [3] Namely, _P. imperialis_, King, and _P. albiventris_ (Lesson). See
  Zool. Chall., Birds, p. 121. It was probably one of these two species
  that Durnford found nesting on Tombo Point, south of Chupat (_cf._
  Ibis, 1878, p. 399).

Azara tells us that this Cormorant is not uncommon in Paraguay, and Mr.
Barrows found it an "abundant resident" at Concepcion in Entrerios.

In the vicinity of Buenos Ayres several well-known authorities have met
with it, and Durnford found it common and resident in Chupat.

The name of Brazilian Cormorant, which naturalists have bestowed on this
species, is certainly inappropriate and misleading, since the bird is
very abundant in La Plata, where the native name for it is _Viguá_;
and it is also very common in the Patagonian rivers. It is always seen
swimming, sinking its heavy body lower and lower down in the water
when approached, until only the slanting snake-like head and neck are
visible; or else sitting on the bank, or on a dead projecting branch,
erect, and with raised beak, and never moving from its statuesque
attitude until forced to fly. It always rises reluctantly and with great
labour, and has a straight rapid flight, the wings beating incessantly.
By day it is a silent bird, but when many individuals congregate to
roost on the branches of a dead tree overhanging the water they keep up
a concert of deep, harsh, powerful notes all night long, which would
cause any person not acquainted with their language to imagine that
numerous pigs or peccaries were moving about with incessant gruntings
in his neighbourhood.



About thirty different species of the fish-eating family Ardeidæ occur
within the limits of the Neotropical Region. Of these, eight or nine are
found in greater or less abundance in the provinces of the Argentine
Republic. Five of these species are widely distributed in North and
South America; the others are restricted to the southern portions of the
New World.

315. ARDEA COCOI, Linn.


  +Ardea cocoi+, _Burm. La-Plata Reise_, ii. p. 508 (Paraná, Tucuman,
      Cordova); _Scl. et Salv. Nomencl._ p. 125; _Hudson, P. Z. S._
      1875, p. 625 (Buenos Ayres); _Durnford, Ibis_, 1877, p. 189
      (Buenos Ayres), et 1878, p. 399 (Patagonia); _Gibson, Ibis_,
      1880, p. 158 (Buenos Ayres); _White, P. Z. S._ 1883, p. 41
      (Cordova); _Barrows, Auk_, 1884, p. 271 (Entrerios).

    _Description._--Above grey; head above, wings, and tail plumbeous
    black; beneath white, neck and sides of belly striped with black:
    whole length 36·0 inches, wing 18·0, tail 7·0. _Female_ similar.

_Hab._ North and South America.

In size, form, and colour the Cocoi closely resembles the Common Heron
of Europe; in flight, language, and feeding-habits the two species
are identical, albeit inhabiting regions so widely separated. In the
southern part of South America it is not seen associating with its
fellows, nor does it breed in heronries; but this may be owing to
the circumstance that in the temperature countries it is very thinly
distributed, and it is highly probable, I think, that in the hotter
regions, where it is more abundant, its habits may not appear so
unsocial. Though they are always seen fishing singly, they pair for
life, and male and female are never found far apart, but haunt the same
stream or marsh all the year round. Azara says that in Paraguay, where
it is very scarce, it goes in pairs and breeds on trees. On the pampas
it makes its solitary nest amongst the rushes, and lays three blue eggs.

The following general remarks on the Heron apply chiefly to the _Ardea
cocoi_, and to some extent also to other species of the Heron family.

I have observed Herons a great deal, and think that there is much to be
said in support of Buffon's opinion that they are wretched, indigent
birds, condemned by the imperfection of their organs for a perpetual
struggle with misery and want.

Much as the different species vary in size, from the _Ardea cocoi_ to
the diminutive Variegated Heron of Azara (_Ardetta involucris_), no
bigger than a Snipe, there is yet much sameness in their conformation,
language, flight, nesting and other habits. They possess a snake-like
head and neck, and a sharp taper beak, with which they transfix their
prey as with a dart--also the serrate claw, about which so much has been
said, and which has been regarded as an instance of pure adaptation. A
curious circumstance has come under my observation regarding Herons.
Birds in poor condition are very much infested with vermin; whether the
vermin are the cause or effect of the poor condition, I do not know; but
such is the fact. Now in this region (the Argentine Republic) Herons
are generally very poor, a good-conditioned bird being a very rare
exception; a majority of individuals are much emaciated and infested
with intestinal worms; yet I have never found a bird infested with lice,
though the Heron would seem a fit subject for them, and in the course of
my rambles I have picked up many individuals apparently perishing from
inanition. I do not wish to insinuate a belief that this immunity from
vermin is due to the pectinated claw; for though the bird does scratch
and clean itself with the claw, it could never rid the entire plumage
from vermin by this organ, which is as ill adapted for such a purpose
as for "giving a firmer hold on its slippery prey."

The Spoonbill has also the serration, and is, unlike the Heron, an
active vigorous bird and usually fat; yet it is much troubled with
parasites, and I have found birds too weak to fly and literally swarming
with them.

I merely wish to call the attention of ornithologists to the fact
that in the region where I have observed Herons they are exempt in a
remarkable degree from external parasites.

Much has also been said about certain patches of dense, clammy,
yellowish down under the loose plumage of Herons. These curious
appendages may be just as useless to the bird as the tuft of hair on its
breast is to the Turkey-cock; but there are more probabilities the other
way, and it may yet be discovered that they are very necessary to its
well-being. Perhaps these clammy feathers contain a secretion fatal to
the vermin by which birds of sedentary habits are so much afflicted, and
from which Herons appear to be so strangely free. They may even be the
seat of that mysterious phosphorescent light which some one has affirmed
emanates from the Heron's breast when it fishes in the dark, and which
serves to attract the fish, or to render them visible to the bird.
Naturalists have, I believe, dismissed the subject of this light as a
mere fable without any foundation of fact; but real facts regarding
habits of animals have not unfrequently been so treated. Mr. Bartlett's
interesting observations on the Flamingoes in the Society's Gardens show
that the ancient story of the Pelican feeding its young on its own blood
is perhaps only a slightly embellished account of a common habit of the

I have not observed Herons fishing by night very closely, but there is
one fact which inclines me to believe it probable that some species
might possess the light-emitting power in question. I am convinced that
the _Ardea cocoi_ sees as well by day as other diurnal species; the
streams on the level pampas are so muddy that a fish two inches below
the surface is invisible to the human eye, yet in these thick waters
the Herons fish by night and by day. If the eye is adapted to see
well with the bright sun shining, how can it see at night and in such
unfavourable circumstances without some such extraneous aid to vision as
the attributed luminosity?

Herons, of all birds, have the slowest flight; but though incapable of
progressing rapidly when flying horizontally, when pursued by a Hawk the
Heron performs with marvellous ease and grace an aerial feat unequalled
by any other bird, namely, that of rising vertically to an amazing
height in the air. The swift vertical flight with which the pursued
ascends until it becomes a mere speck in the blue zenith, the hurried
zigzag flight of the pursuer, rising every minute above its prey, only
to be left below again by a single flap of the Heron's wings, forms a
sight of such grace, beauty, and power, as to fill the mind of the
spectator with delight and astonishment.

When the enemy comes to close quarters, the Heron instinctively throws
itself belly up to repel the assault with its long, crooked, cutting
claws. Raptorial species possess a similar habit; and the analogous
correlation of habit and structure in genera so widely separated is very
curious. The Falcon uses its feet to strike, lacerate, and grasp its
prey; the Heron to anchor itself firmly to its perch; but for weapons of
defence they are equally well adapted, and are employed in precisely the
same manner. The Heron, with its great length of neck and legs, its lean
unballasted body, large wings, and superabundance of plumage, is the
least suited of birds to perch high; yet the structure of the feet
renders it perfectly safe for the bird to do so. Thus the Heron is
enabled to sit on a smooth enamelled rush or on the summit of a tree,
and doze securely in a wind that, were its feet formed like those of
other Waders, would blow it away like a bundle of dead feathers.

Another characteristic of Herons is that they carry the neck, when
flying, folded in the form of the letter S. At other times the bird also
carries the neck this way; and it is, indeed, in all long-necked species
the figure the neck assumes when the bird reposes or is in the act of
watching something below it; and the Heron's life is almost a perpetual
watch. Apropos of this manner of carrying the neck, so natural to the
bird, is it not the cause of the extreme wariness observable in Herons?
Herons are, I think, everywhere of a shy disposition; with us they are
the wildest of water-fowl, yet there is no reason for their being so,
since they are never persecuted.

Birds ever fly reluctantly from danger; and all species possessing the
advantage of a long neck, such as the Swan, Flamingo, Stork, Spoonbill,
&c., will continue with their necks stretched to their utmost capacity
watching an intruder for an hour at a time rather than fly away. But
in the Herons it must be only by a great effort that the neck can
be wholly unbent; for even if the neck cut out from a dead bird be
forcibly straightened and then released, it flies back like a piece of
india-rubber to its original shape. Therefore the effort to straighten
the neck, invariably the first expression of alarm and curiosity, must
be a painful one; and to keep it for any length of time in that position
is probably as insupportable to the bird as to keep the arm straightened
vertically would be to a man. Thus the Heron flies at the first sight of
an intruder, whilst the persecuted Duck, Swan, or other fowl continues
motionless, watching with outstretched neck, participating in the alarm
certainly, but not enduring actual physical pain.

Doubtless in many cases habits react upon and modify the structure
of parts; and in this instance the modified structure has apparently
reacted on and modified the habits. In seeking for and taking food,
the body is required to perform certain definite motions and assume
repeatedly the same attitudes; this is most frequently the case in
birds of aquatic habits. A facility for assuming at all times, and an
involuntary falling into, these peculiar attitudes and gestures appears
to become hereditary; and the species in which they are the most
noticeable seem incapable of throwing the habit or manner off, even when
placed in situations where it is useless or even detrimental. _Tringæ_
rapidly peck and probe the mud as they advance; Plovers peck and run,
peck and run again. Now I have noticed scores of times that these birds
cannot possibly lay aside this habit of pecking as they advance; for
even a wounded Plover running from his pursuer over dry barren ground
goes through the form of eating by pausing for a moment every yard or
so, pecking the ground, then running on again.

The Paraguay Snipe, and probably other true Snipes, possesses the
singular habit of striking its beak on the ground when taking flight.
In this instance has not the probing motion, performed instinctively as
the bird moves, been utilized to assist it in rising?

Grebes on land walk erect like Penguins and have a slow awkward
gait; and whenever they wish to accelerate their progress they throw
themselves forward on the breast and strike out the feet as in swimming.

The Glossy Ibis feeds in shallow water, thrusting its great sickle beak
into the weeds at the bottom at every step. When walking on land it
observes these motions, and seems incapable of progressing without
plunging its beak downwards into imaginary water at every stride.

The Spoonbill wades up to its knees and advances with beak always
immersed, and swaying itself from side to side, so that at each lateral
movement of the body the beak describes a great semicircle in the
water; a flock of these birds feeding reminds one of a line of mowers
mowing grass. On dry ground the Spoonbill seems unable to walk directly
forward like other birds, but stoops, keeping the body in a horizontal
position, and, turning from side to side, sweeps the air with its beak,
as if still feeding in the water.

In the foregoing instances (and I could greatly multiply them), in which
certain gestures and movements accompany progressive motion, it is
difficult to see how the structure can be in any way modified by them;
but the preying attitude of the Heron, the waiting motionless in
perpetual readiness to strike, has doubtless given the neck its very
peculiar form.

Two interesting traits of the Heron (and they have a necessary
connexion) are its tireless watchfulness and its insatiable voracity;
for these characters have not, I think, been exaggerated even by the
most sensational of ornithologists.

In birds of other genera, repletion is invariably followed by a period
of listless inactivity during which no food is taken or required. But
the Heron digests his food so rapidly that, however much he devours, he
is always ready to gorge again; consequently he is not benefited by what
he eats, and appears in the same state of semi-starvation when food is
abundant as in times of scarcity. An old naturalist has suggested, as
a reason for this, that the Heron, from its peculiar manner of taking
its prey, requires fair weather to fish--that during spells of bad
weather, when it is compelled to suffer the pangs of famine inactive, it
contracts a meagre consumptive habit of body, which subsequent plenty
cannot remove. A pretty theory, but it will not hold water; for in this
region spells of bad weather are brief and infrequent; moreover, all
other species that feed at the same table with the Heron, from the
little flitting Kingfisher to the towering Flamingo, become excessively
fat at certain seasons, and are at all times so healthy and vigorous
that, compared with them, the Heron is the mere ghost of a bird. In no
extraneous circumstances, but in the organization of the bird itself,
must be sought the cause of its anomalous condition; it does not appear
to possess the fat-elaborating power, for at no season is any fat found
on its dry starved flesh; consequently there is no provision for a rainy
day, and the misery of the bird (if it is miserable) consists in its
perpetual, never-satisfied craving for food.

_Hab._ North and South America.

The White Egret inhabits America from Nova Scotia to Patagonia, and
is everywhere common, so that its breeding and other habits are very
well known. On the pampas, owing to the absence of forests, its
nesting-habits have been modified, for there it makes its nest amongst
the reeds; as do also other species which elsewhere in America, North
and South, build on trees. The following interesting account of a
heronry on the pampas is from a paper by Mr. Gibson:--

"In November of 1873 I found a large breeding-colony of _Ardea egretta_,
_A. candidissima_, and _Nycticorax obscurus_ in the heart of a lonely
swamp. The rushes were thick, but had been broken down by the birds in a
patch some fifty yards in diameter. There were from 300 to 400 nests, as
well as I could judge; of these three fourths were of _A. egretta_,
and the remainder, with the exception of two or three dozen of _N.
obscurus_, belonged to _A. candidissima_. Those of the first-mentioned
species were slight platforms, placed on the tops of broken rushes, at
a height of from two to three feet above the water, and barely a yard

"The nests of _A. candidissima_ were built up from the water to the
height of a foot or a foot and a half, with a hollow on the top for the
eggs; they were very compactly put together, of small dry twigs of a
water-plant. A good many were distributed amongst those of _A. egretta_;
but the majority were close together, at one side of the colony, where
the reeds were taller and less broken.

"The nests of _N. obscurus_ much resembled the latter in construction
and material; but very few were interspersed amongst those of the other
two species, being retired to the side opposite _A. candidissima_, on
the borders of some channels of clear water; there they were placed
amongst the high reeds, and a few yards apart from each other.

"The larger Egrets remained standing on their nests till I was within
twenty yards of them, and alighted again when I had passed. In this
position they looked much larger than when flying. The smaller Egrets
first flew up onto the reeds above the nests, and then immediately took
to flight, not returning; while _N. obscurus_ rose and sailed away,
uttering a deep _squawk, squawk_, long before one came near the nest.

"At one side of the colony a nest of _Ciconia maguari_, with two
full-grown young, seemed like the reigning house of the place.

"It certainly was one of the finest ornithological sights I ever saw:
all around a wilderness of dark green rushes, rising above my head as
I sat on horseback; the cloud of graceful snow-white birds perched
everywhere, or reflected in the water as they flew to and fro overhead;
and the hundreds of blue eggs exposed to the bright sunlight.

"_A. egretta_ and _A. candidissima_ lay four eggs each, though the
former rarely hatches out more than three. _N. obscurus_ lays and
hatches out three. The eggs of all three species are of the same shade
of light blue."

The Snowy Egret is common on the pampas, and throughout all the warm
portions of North and South America; but does not range so far south as
_Ardea egretta_. It is a very pretty bird in its dazzling white plumage,
and is more active and social in its habits than most Herons, being
usually seen in small flocks, and often associates with Ibises and other
aquatic species. An account of its breeding-habits has already been

This well-known North-American Heron extends far to the south. Natterer
obtained examples at several places in the province of Sao Paolo,

and also near Mercedes in the Argentine Republic.

This is a beautiful bird, with plumage as soft as down to the touch. Its
colours are clear blue-grey and pale yellow, the under surface being
nearly white. In some specimens that I have obtained the rump and
tail-coverts had a pure primrose hue. There is a chestnut mark on the
side of the head; the eye is white, and the legs dark green in life.

Azara named this Heron "_Flauta del Sol_" (flute of the sun), a
translation of the Indian term _Curahí-remimbí_, derived from the
popular belief that its whistling notes, which have a melodious and
melancholy sound, prophesy changes in the weather.

It comes as far south as Buenos Ayres, but is only a summer visitor
there, and very scarce. Having seen but little of it myself, I can only
repeat Azara's words concerning it. He says it is common in Paraguay,
going in pairs or families, and perches and roosts on trees, and when
flying flaps its wings more rapidly than other Herons. It makes its nest
on a tree, and lays two clear blue eggs.

On the Lower Uruguay, Mr. Barrows likewise found this species "not
common." It was only seen a few times in November. "Though most
resembling the Night-Heron they were active by day, and when disturbed
flew rapidly away from the streams and swamps towards the dry woods and

The Little Blue Heron, though widely distributed, is not anywhere a
common bird. I have always seen them singly, for it loves a hermit-life,
and the feeding-ground it prefers is a spot on the borders of a marshy
stream shut in and overshadowed on all sides by trees and tall rushes.
There the bird sits silent and solitary on a projecting root or dead
branch; or stands motionless and knee-deep in the water, intent on the
small fry it feeds on. For whole months it will be found every day in
the same place. When intruded on in its haunt it erects the feathers of
its head and neck, looking strangely alarmed or angry, and flies away
uttering a powerful harsh grating cry.

Its nesting-habits I do not know; but Mr. Barrows says that it
undoubtedly breeds near Concepcion on the Lower Uruguay, where it is
abundant in spring and summer.

The Variegated Heron is the least of the family to which it belongs, its
body being no bigger than that of the Common Snipe; but in structure
it is like other Herons, except that its legs are a trifle shorter in
proportion to its size and its wings very much shorter than in other
species. The under plumage is dull yellow in colour, while all the other
parts are variegated with marks of fuscous and various shades of brown
and yellow. The body is extremely slim, and the lower portion of the
neck covered with thick plumage, giving that part a deceptively massive
appearance. The perching faculty, possessed in so eminent a degree by
all Herons, probably attains its greatest perfection in this species,
and is combined with locomotion in a unique and wonderful manner. It
inhabits beds of rushes growing in rather deep water; very seldom, and
probably only accidentally, does it visit the shore, and only when
driven up does it rise above the rushes; for its flight, unlike that of
its congeners, is extremely feeble. The rushes it lives amongst rise,
smooth as a polished pipe-stem, vertically from water too deep for the
bird to wade in; yet it goes up to the summit and down to the surface,
moving freely and briskly about amongst them, or runs in a straight line
through them almost as rapidly as a Plover can run over the bare level
ground. Unless I myself had been a witness of this feat, I could
scarcely have credited it; for how does it manage to grasp the smooth
vertical stems quickly and firmly enough to progress so rapidly without
ever slipping down through them?

The Variegated Heron is a silent solitary bird, found everywhere in the
marshes along the Plata, as also in the reed-beds scattered over the
pampas. It breeds amongst the rushes, and lays from three to five
spherical eggs, of a rich lively green and beautiful beyond comparison.
The nest is a slight platform structure about a foot above the water,
and so small that there is barely space enough on it for the eggs, which
are large for the bird. When one looks down on them they cover and hide
the slight nest, and being green like the surrounding rushes they are
not easy to detect.

When driven up the bird flies eighty or a hundred yards away, and drops
again amongst the rushes; it is difficult to flush it a second time, and
a third time it is impossible. A curious circumstance is that where
it finally settles it can never be found. As I could never succeed in
getting specimens when I wanted them, I once employed some Gaucho boys,
who had dogs trained to hunt young Ducks, to try for this little Heron.
They procured several specimens, and said that without the aid of their
dogs they could never succeed in finding a bird, though they always
marked the exact spot where it alighted. This I attributed to the
slender figure it makes, and to the colour of the plumage so closely
assimilating to that of the dead yellow and brown-spotted rushes always
found amongst the green ones; but I did not know for many years that the
bird possessed a marvellous instinct that made its peculiar conformation
and imitative colour far more advantageous than they could be of

One day in November 1870, when out shooting, I noticed a Variegated
Heron stealing off quickly through a bed of rushes thirty or forty yards
from me; he was a foot or so above the ground, and went so rapidly that
he appeared to glide through the rushes without touching them. I fired,
but afterwards ascertained that in my hurry I missed my aim. The bird,
however, disappeared at the report; and thinking I had killed him, I
went to the spot.

It was a small isolated bed of rushes I had seen him in; the mud below
and for some distance round was quite bare and hard, so that it would
have been impossible for the bird to escape without being perceived; and
yet, dead or alive, he was not to be found. After vainly searching and
researching through the rushes for a quarter of an hour I gave over the
quest in great disgust and bewilderment, and, after reloading, was just
turning to go, when, behold! there stood my Heron on a reed, no more
than eight inches from, and on a level with, my knees. He was perched,
the body erect, and the point of the tail touching the reed grasped by
its feet; the long slender tapering neck was held stiff, straight and
vertically; and the head and beak, instead of being carried obliquely,
were also pointing up. There was not, from his feet to the tip of his
beak, a perceptible curve or inequality, but the whole was the figure
(the exact counterpart) of a straight tapering rush: the loose plumage
arranged to fill inequalities, and the wings pressed into the hollow
sides, made it impossible to see where the body ended and the neck
began, or to distinguish head from neck or beak from head. This was, of
course, a front view; and the entire under surface of the bird was thus
displayed, all of a uniform dull yellow, like that of a faded rush. I
regarded the bird wonderingly for some time; but not the least motion
did it make. I thought it was wounded or paralyzed with fear, and,
placing my hand on the point of its beak, forced the head down till it
touched the back; when I withdrew my hand, up flew the head, like a
steel spring, to its first position. I repeated the experiment many
times with the same result, the very eyes of the bird appearing all the
time rigid and unwinking like those of a creature in a fit. What wonder
that it is so difficult, almost impossible, to discover the bird in such
an attitude! But how happened it that while repeatedly walking round the
bird through the rushes I had not caught sight of the striped back
and the broad dark-coloured sides? I asked myself this question, and
stepped round to get a side view, when, _mirabile dictu_, I could still
see nothing but the rush-like front of the bird! His motions on the
perch, as he turned slowly or quickly round, still keeping the edge of
the blade-like body before me, corresponded so exactly with my own that
I almost doubted that I had moved at all. No sooner had I seen the
finishing part of this marvellous instinct of self-preservation (this
last act making the whole complete), than such a degree of delight
and admiration possessed me as I have never before experienced during
my researches, much as I have conversed with wild animals in the
wilderness, and many and perfect as are the instances of adaptation I
have witnessed. I could not finish admiring, and thought that never had
anything so beautiful fallen in my way before; for even the sublime
cloud-seeking instinct of the White Egret and the typical Herons seemed
less admirable than this; and for some time I continued experimenting,
pressing down the bird's head and trying to bend him by main force into
some other position; but the strange rigidity remained unrelaxed, the
fixed attitude unchanged. I also found, as I walked round him, that, as
soon as I got to the opposite side and he could no longer twist himself
on his perch, he whirled his body with great rapidity the other way,
instantly presenting the same front as before.

Finally I plucked him forcibly from the rush and perched him on my hand,
upon which he flew away; but he flew only fifty or sixty yards off,
and dropped into the dry grass. Here he again put in practice the same
instinct so ably that I groped about for ten or twelve minutes before
refinding him, and was astonished that a creature to all appearance so
weak and frail should have strength and endurance sufficient to keep its
body rigid and in one attitude for so long a time.

Our figure of this species (Plate XVII.) is taken from a skin in
Sclater's collection, which was procured by Mr. F. Withington in the
Lomas de Zamora in 1883.

Graf v. Berlepsch has recently shown that the Tiger-Bittern of Paraguay
differs from _Tigrisoma brasiliense_ (which it generally resembles in
plumage) in having the base of the lower mandible partly feathered as in
_T. fasciatum_. It is probable that the Argentine Tiger-Bittern belongs
to the same form, but we have not yet met with adult specimens of it. It
occurs in the northern provinces of the Republic, and was obtained by
White in Corrientes, and by Durnford in Salta.

In the Argentine Republic the Night-Heron lives in communities, and
passes the hours of daylight perched inactive on large trees or in
marshes on the rushes, and when disturbed by day they rise up with heavy
flappings and a loud _qua-qua_ cry. At sunset they quit their retreat,
to ascend a stream or seek some distant feeding-ground, and travel with
a slow flight, bird succeeding bird at long intervals, and uttering
their far-sounding, hoarse, barking night-cry.

Where the flock lives amongst the rushes, in places where there are
no trees, the birds, by breaking down the rushes across each other,
construct false nests or platforms to perch on. These platforms are
placed close together, usually where the rushes are thickest, and serve
the birds for an entire winter.

The breeding-habits of the Night-Heron have already been described in
the account of the _Ardea egretta_.

In the Falkland Islands, where Captain Abbott discovered a heronry
(_cf._ Ibis, 1861, p. 157), their breeding-habits are the same as on the


The Storks constitute a small but well-defined family of the Order
Herodiones, allied to the Ardeidæ, but distinguished by the elevated
hallux, their non-pectinated middle claw, and the absence of powder-down
patches in the plumage. They are divisible into two sub-families--the
true Storks, and the Wood-Ibises (Tantalinæ). Two of the former group
and one of the latter occur within our limits, and two of these three
species range throughout tropical America up to the Southern United

This is a majestic bird, the largest of the American Storks; it stands
five feet high, and the wings have a spread of nearly eight feet. The
entire plumage is pure white, the head and six inches of the neck
covered with a naked black skin; from the black part extend two scarlet
bands, the skin being glossy and exceedingly loose, and run narrowing
down to the chest. When the bird is wounded or enraged, this loose red
skin is said to swell out like a bladder, changing to an intensely fiery
scarlet hue. The name "_Jabiru_" is doubtless due to this circumstance,
for Azara (who gives the Guarani name of the Stork as _Aiaiai_) says
that the Indian word _Yabirú_ signifies blown out with wind.

The Jabiru is but rarely found near Buenos Ayres, but occurs more
frequently in Misiones, and in other districts on the northern frontiers
of the Republic. It nests on high trees, as has been recorded by
Brown[4], and is said to lay "blue-green" eggs.

The Maguari Stork is a well-known bird on the pampas, breeding in the
marshes, and also wading for its food in the shallow water; but it
is not nearly so aquatic in its habits as the Jabiru, and after the
breeding-season is over it is seen everywhere on the dry plains. Here
these birds prey on mice, snakes, and toads, but also frequently
visit the cultivated fields in quest of food. When mice or frogs are
exceptionally abundant on the pampas, the Storks often appear in large
numbers, and at such times I have seen them congregating by hundreds in
the evening beside the water; but in the daytime they scatter over the
feeding-ground, where they are seen stalking along, intent on their
prey, with majestic Crane-like strides. To rise they give three long
jumps before committing themselves to the air, and like all heavy fliers
make a loud noise with their wings. They are never seen to alight on
trees, like the Jabiru, and are absolutely dumb, unless the clattering
they make with the bill when angry can be called a language.

The laying-time is about the middle of August, and the nest is built
up amongst the rushes, rising about two feet above the surface of the
water. The eggs are rather long, three or four in number, and of a
chalky white.

Mr. Gibson, of Buenos Ayres, furnishes the following lively account of a
young Maguari:--"One, which I took on October 5, was about the size of
a domestic fowl, in down, and, with the exception of the white tail,
entirely black. It soon became very tame, and used to wander all over
the premises, looking for food, or watching any work that was going on.
Rats were swallowed whole; and the way it would gulp down a pound or
two of raw meat would have horrified an English housekeeper. Snakes it
seized by the nape of the neck, and passed them transversely through its
bill by a succession of rapid and powerful nips, repeating the operation
two or three times before being satisfied that life was totally extinct.
It used often to do the same thing with dry sticks (in order not to
forget the way, I suppose); while on one occasion it swallowed a piece
of hard cowhide, a foot long, and consequently could not bend its neck
for twenty-four hours after--till the hide softened, in fact. The story
also went that 'Byles, the lawyer' (as he was called), mistook the
tail of one of the pet lambs for a snake, and actually had it down his
throat, but was 'brought up' by the body of the lamb! Byles inspired a
wholesome respect in all the dogs and cats, but was very peaceable as
a rule. One of our men had played some trick on him, however; and the
result was that Byles generally went for him on every possible occasion,
his long legs covering the ground like those of an Ostrich, while he
produced a demoniacal row with his bill. It was amusing to see his
victim dodging him all over the place, or sometimes, in desperation,
turning on him with a stick; but Byles evaded every blow by jumping
eight feet into the air, coming down on the other side of his enemy and
there repeating his war dance; while he always threatened (though his
threats were never fulfilled) to make personal and pointed remarks with
his formidable bill.

"Shortly after his capture feathers began to appear; and the
following is a description of the bird at the age of about two
months:--Tail-feathers white, remainder of plumage glossy green-black;
bill black; legs and feet grey. Spots and patches of white began to
appear on head, back, and wings; these gradually extended, until, by
the end of May, the adult plumage was all acquired. Then my interest in
Byles ceased, and latterly he strayed away to his native swamps."

Most people in the Plata region are familiar with this bird of the
marshes, its lofty stork-like figure and white plumage making it a very
conspicuous object.

On the pampas it is not uncommon in summer and autumn, and goes in
flocks of a dozen or twenty. The birds are usually seen standing
motionless in groups or scattered about in spiritless attitudes,
apparently dozing away the time. On the wing it appears to better
advantage, having a singularly calm stately flight; on a warm still day
they are often seen soaring in circles very far up in the sky.

I have never heard of this bird nesting on the pampas, and am inclined
to think that it only breeds in forest-regions, and visits the marshes
in the treeless districts after the young have flown.

Its habits in North America, where it is called the "Wood-Ibis," are
tolerably well known, and in the ornithological works of that country
it is described as "a hermit standing listless and alone on the topmost
limb of some tall decayed cypress, its neck drawn in upon its shoulders,
and its enormous bill resting like a scythe upon its breast."

It there nests on tall trees, sometimes in company with Egrets, and lays
three white eggs.


The Spoonbills and Ibises constitute a homogeneous family of Herodiones,
which have a wide distribution over the earth's surface, although mostly
prevalent within intertropical limits. They fall naturally into two
groups--the Ibises, distinguished by their elongated, compressed, and
sickle-shaped bills; and the Spoonbills, at once known by the peculiar
form of the same organ, which is much expanded at its termination.
Of about twenty-five known species of Ibises, the Neotropical Region
possesses eight or nine, and of these four occur in Argentina. Of the
Spoonbills only one is Neotropical, and that is met with throughout the
southern portion of South America.

This form of the well-known "Glossy Ibis" of Europe is one of our most
abundant waterfowl on the pampas, and appears in spring in flocks; but
as their movements are somewhat irregular and many individuals remain
with us through the winter, their migrations probably do not extend
very far. In summer they are found beside every marsh and watercourse,
briskly wading about in the shallow water and plunging their long curved
beaks downwards at every step. When taking wing they invariably utter a
loud _ha ha ha_, resembling hearty human laughter, but somewhat nasal in
sound. They frequently leave the marshy places and are seen scattered
about the grassy plains, feeding like land-birds; and on the pampas they
often congregate about the carcass of a dead horse or cow, to feed on
the larvæ of the flesh-fly in company with the Milvago and the Hooded

Their flight is singularly graceful; and during migration the flocks are
seen to follow each other in rapid succession, each flock being usually
composed of from fifty to a hundred individuals, sometimes of a much
larger number. It is most interesting to watch them at such times, now
soaring high in the air, displaying the deep chestnut hue of their
breasts, then descending with a graceful curve towards the earth, as if
to exhibit the dark metallic green and purple reflexions of their
upper plumage. The flock is meanwhile continually changing its form or
disposition, as if at the signal of a leader. One moment it spreads out
in a long straight line; suddenly the birds scatter in disorder, or
throw themselves together like a cloud of Starlings; as suddenly they
again reform to continue their journey in the figure of a phalanx,
half-moon, or triangle. The fanciful notion can scarcely fail to suggest
itself to the spectator that the birds go through these unnecessary
evolutions intelligently in order to attain a greater proficiency in
them by practice, or, perhaps, merely to make a display of their aerial
accomplishments. The Glossy Ibis has another remarkable habit when
on the wing. At times the flock appears as if suddenly seized with
frenzy or panic, every bird rushing wildly away from its fellows, and
descending with a violent zigzag flight; in a few moments the mad fit
leaves them, they rise again, reassemble in the air, and resume their

This very fine Ibis, called _Mandurria ó curucáu_ by Azara and _Vanduria
de Invierno_ (winter Vanduria) in the vernacular, is one of the most
interesting winter visitors from Patagonia to the pampas of Buenos
Ayres. It is found in Chili, and has even been obtained as far north as
Peru. On the east side of the continent it is most abundant (during
the cold season) about latitude 37° or 38°. Its summer home and
breeding-ground appears to be in the extreme south of the continent,
its eggs having been obtained in the Straits of Magellan by Darwin, and
recently by Dr. Cunningham, who only says of it that it is a shy and
wary bird, that goes in flocks of from four to eight, and has a cry
resembling _qua-qua, qua-qua_. But he might just as well have spelt it
_quack-quack_, since _qua-qua_ fails to give the faintest idea of the
series of hard abrupt notes of extraordinary power the bird utters,
usually when on the wing, which sound like blows of a powerful hammer
on a metal plate. On the pampas this Ibis appears in May, frequents
dry grassy situations, and goes in flocks of a dozen to forty or fifty
individuals. They walk rapidly, stooping very much, and probing the
ground with their long slender curved beaks, and appear to subsist
principally on the larvæ of the large, horned beetle, with which their
stomachs are usually found filled. So intent are they on seeking their
food that the members of a flock often scatter in all directions
and wander quite out of sight of each other; when this happens they
occasionally utter loud vehement cries, as if to call their companions,
or to inform each other of their whereabouts. Frequently one is seen to
lift up its wings as if to fly, and, stretching them up vertically, to
remain for fifteen or twenty seconds in this curious attitude. At sunset
they all rise up clamouring, and direct their flight to the nearest
watercourse, and often on their way thither go through a strange
and interesting performance. The flock suddenly precipitates itself
downwards with a violence wonderful to see, each bird rushing this way
and that as if striving to outvie its fellows in every wild fantastic
motion of which they are capable. In this manner they rise and descend
again and again, sometimes massed together, then scattered wide apart
in all directions. This exercise they keep up for some time, and while
it lasts they make the air resound for miles around with their loud
percussive screams.

In Patagonia I first observed this Ibis roosting on tall trees; and,
according to Azara, it possesses the same habit in Paraguay. He says
that all the flocks within a circuit of some leagues resort to one spot
to sleep, and prefer tall dead trees bordering on the water, and if
there is only one suitable tree all the birds crowd on to it, and in the
morning scatter, each family or pair flying away to spend the day in its
customary feeding-ground.

The egg obtained by Dr. Cunningham at Elizabeth Island is thus described
by Prof. Newton (Ibis, 1870, p. 502)[5]:--"Dull surface of a pale
greenish white with engrained blotches (mostly small) of neutral tint,
and some few blotches, spots, and specks of dull deep brown; towards the
larger end some hair-like streaks of a lighter shade of the same, and so
far having an Ibidine or Plataleine character."

_Hab._ South-east Brazil and Argentina.

This noble Ibis ranges from Brazil, south of the Amazons, to the pampas
of Buenos Ayres. It is a bird of the marshes, nowhere abundant, and yet
is exceedingly well known to most people in the Argentine country: it
would be difficult indeed to overlook a species possessing so peculiar
and powerful a voice. In the vernacular it is called _Vanduria_, with
the addition of _aplomado_, or _barroso_, or _de las lagunas_, to
distinguish it from the Winter Vanduria. The word is also frequently
spelt _Manduria_ or _Banduria_, but it does not come from _Bandada_
(flock), as Mr. Barrows imagines when he gives this vernacular name
to the Glossy Ibis; but from the Spanish stringed instrument called
Vanduria. Possibly the instrument is obsolete now; not so the word,
however, and it is sometimes used by the poets, instead of "harp" or
"lyre," to symbolize poetic inspiration. Thus Iriarte:--

          "Atencion! que la vanduria he templado."

If one could get a banjo with brass strings so big that it could be
heard a mile and a half away, a dozen strokes dealt in swift succession
on one string would produce a sound resembling the call of this Ibis--a
voice of the desolate marshes, which competes in power with the
outrageous human-like shrieks of the Ypecaha Rail, the long resounding
wails of the Crazy Widow or Courlan, and the morning song of the Crested

The Vanduria is usually seen singly or in pairs, and sometimes, but
rarely, in small companies of half a dozen birds. In its habits it
is like a Tantalus, wading in the shallow water of the marshes, and
devouring eels, frogs, fish, &c. After examining the well-filled
stomachs of a few individuals, one is strongly tempted to believe that
the beautiful long beak of this Ibis has "forgotten its cunning" as a
probe. At intervals in the daytime it utters, standing on the ground,
its resonant metallic cry. It is wary and has a strong easy flight, and
is a great wanderer, but I am not able to say whether it possesses a
regular migration or not.

The celebrated naturalist Natterer procured specimens of this Ibis in
the lagoons of Caiçara, in the Brazilian Province of Matogrosso, in
September and November, 1825, but it is not mentioned by general writers
on the birds of S.E. Brazil.

_Hab._ South America from Colombia south to Argentina.

Of this Ibis, which ranges from Colombia to the Argentine Republic, a
few individuals come as far south as the pampas of Buenos Ayres.

The fore part of the head and throat being unfeathered, suggested to
Azara the name of _Afeytado_, or "shaved," but about its habits he has
nothing to say, nor does he mention its peculiar voice, or, perhaps it
would be more correct to say, its want of voice; for it seems quite
silent unless one comes near to it and listens very intently, when he
will be able to hear little sigh-like puffs of sound as the bird flies
away. It seems strange that this member of a loquacious loud-voiced
family should be reduced to speak, as it were, in whispers!

On two or three occasions I have seen as many as half a dozen
individuals together; at other times I have seen one or two associating
with the Glossy Ibis.

Azara's name "Shaved" Ibis seems well enough in Spanish, just as his
"Throat-cut" for a Starling with a scarlet throat does not strike one as
at all shocking in that language; but for an English name I fancy that
"Whispering Ibis," from the whisper-like sound the bird emits, would be
more suitable, or, at all events, better sounding.

It is possible that two races of this Ibis exist on the South-American
continent; for in Brazil and further north it is said to have a loud
cry, uttered when taking wing, as in the case of the Glossy Ibis; and
one of its native names in the tropics--_curri-curri_--is said to be an
imitation of its usual note.

_Hab._ North and South America.

The Roseate Spoonbill is found in both Americas and ranges south to the
Straits of Magellan, but in Patagonia it is, I think, rare, for on the
Rio Negro I did not meet with it. On the pampas it is abundant, and I
have been told that it breeds in the marshes there, but I have never
been able to find a nest. It is usually seen in small flocks of from
half a dozen to twenty individuals, which all feed near together, wading
up to their knees and sweeping their long flat beaks from side to side
as they advance. An English acquaintance of mine kept one of these birds
as a pet on his estancia for seven years. It was very docile, and would
spend the day roaming about the grounds, associating with the poultry,
but invariably presented itself in the dining-room at meal-time, where
it would take its station at one end of the table, and dexterously catch
in its beak any morsel thrown to it.

I believe that more than one species of Spoonbill inhabits South
America, and that the common Spoonbill of the pampas is a distinct
species from the well-known Ajaja. Some remarks of mine on this subject
were printed in the 'Proceedings of the Zoological Society of London'
about nine years ago; but I find that I am alone amongst ornithologists
in this belief; I can, therefore, only repeat here what I have said
before, and leave the question for time to decide.

The general belief is that the pale-plumaged birds, with feathered heads
and black eyes (the Roseate Spoonbill having crimson eyes), and without
the bright wing-spots, the tuft on the breast, horny excrescences on the
beak, and other marks, are only immature birds. Now, for one bird with
all these characteristic marks of the true _Platalea ajaja_, which has
a yellow tail, we meet on the pampas with not less than two to three
hundred examples of the pale-plumaged bird without any traces of such
marks and with a rose-coloured tail; and the disparity in number between
mature and immature birds of one species could not well be so great as
that. I have shot one immature specimen of the true Ajaja--so immature
that it seemed not long out of the nest; but the head was bare of
feathers, and it had the knobs on the upper mandible, only they were so
soft that they could be indented with the nail of the finger. Azara also
mentions an immature bird which he obtained, but he does not say that
the head was feathered; and even this negative evidence goes a great
way, since it would have been very unlike him to see a Spoonbill with a
feathered head and otherwise unlike _Ajaja rosea_, and not describe it
as a distinct species.

There are also anatomical differences between the two birds; the
pale-plumaged species having an ordinary trachea, while _A. rosea_ has
a very curiously-formed trachea, unlike that of any other bird, which
has been described by Garrod as follows:--

"The trachea is simple, straight, of uniform calibre, and peculiarly
short, extending only two thirds down the length of the neck, where the
uncomplicated syrinx is situated and the bifurcation of the bronchi
occurs. The usual pair of muscles, one on each side, runs to this
syrinx from above, and ceases there. The bronchi are fusiformly dilated
at their commencement, where the rings which encircle them are not
complete, a membrane taking their place in that portion of each tube
which is contiguous to its opposite neighbour. Each bronchus, lower
down, is composed of complete cartilaginous rings."

The woodcut of this curious structure is here reproduced by the kind
permission of the Zoological Society. It is much to be wished that
some one living in the Argentine Republic would devote himself to the
further investigation of the history of this interesting bird, and
settle the question whether there is more than one species of Argentine

To conclude, I may mention that the pet bird my friend kept was of the
pale-plumaged species, and never lost the feathers from its head, nor
did it acquire any of the characteristic marks of _P. ajaja_.


The very peculiar and isolated type of Flamingo is found in both the
Old and New Worlds, and is, no doubt, of great antiquity. In the
Neotropical Region three species of Flamingo are now known to occur,
one of which is well known in the Argentine Provinces. Of the other
two (_Phœnicopterus andinus_ and _P. jamesi_[6]), which inhabit the
Andes of Chili and Bolivia, one has also been ascertained to occur
within the northern frontiers of the Argentine Republic. Both these
last-named species belong to the three-toed section of the genus
(_Phœnicoparra_). In _P. ignipalliatus_ the hind toe is present.

The Argentine Flamingo inhabits the whole of the Argentine country,
down to the Rio Negro in the south, where I found it very abundant. The
residents told me of a breeding-place there--a shallow salt-lake--which,
however, had been abandoned by the birds before my visit. The nest
there, as in other regions, was a small pillar of mud raised a foot or
eighteen inches above the surface of the water, and with a slight hollow
on the top; and I was assured by people who had watched them on their
nests that the incubating bird invariably sits with the hind part of
the body projecting from the nest, and the long legs dangling down in
the water, and not tucked up under the bird.

On the Rio Negro I found the birds most abundant in winter, which
surprised me, for that there is a movement of Flamingoes to the north in
the autumn I am quite sure, having often seen them passing overhead in a
northerly direction in the migrating-season. I have also found the young
birds, in the grey plumage, at this season in the marshes near to Buenos
Ayres city, hundreds of miles from any known breeding-place. Probably
the birds in the interior of the country, where the cold is far more
intense than on the sea-coast, go north before winter, while those in
the district bordering on the Atlantic have become stationary.

The Flamingo has a curious way of feeding: it immerses the beak, and by
means of a rapid continuous movement of the mandibles passes a current
of water through the mouth, where the minutest insects and particles of
floating matter are arrested by the teeth. The stomach is small, and is
usually found to contain a pulpy mass of greenish-coloured stuff, mixed
with minute particles of quartz. Yet on so scanty a fare this large bird
not only supports itself, but becomes excessively fat. I spent half a
winter in Patagonia at a house built on the borders of a small lake, and
regularly every night a small flock of Flamingoes came to feed in the
water about 200 yards from the back of the house. I used to open
the window to listen to them, and the noise made by their beaks was
continuous and resembled the sound produced by wringing out a wet cloth.
They feed a great deal by day, but much more, I think, by night.

Where they are never persecuted they are tame birds, and when a flock is
fired into and one bird killed, the other birds, though apparently much
astonished, do not fly away. They are silent birds, but not actually
dumb, having a low hoarse cry, uttered sometimes at the moment of taking
flight; also another cry which I have only heard from a wounded bird,
resembling the gobbling of a turkey-cock, only shriller. They are almost
invariably seen standing in the water, even when not feeding, and even
seem to sleep there; on land they have a very singular appearance, their
immense height, in proportion to their bulk, giving them an appearance
amongst birds something like that of the giraffe amongst mammals. To the
lakes and water-courses in the midst of the grey scenery of Patagonia
they seem to give a strange glory, while standing motionless, their tall
rose-coloured forms mirrored in the dark water, but chiefly when they
rise and pass in a long crimson train or phalanx, flying low over the

The Andean Flamingo, which is at once distinguishable from _P.
ignipalliatus_ by the complete absence of the hind toe, is stated by Dr.
Burmeister, on the authority of Herr Schickendantz, to be found on the
north-western frontiers of the Argentine Republic, on the lagunes of the
eastern valleys between the Cordilleras and the adjacent mountains.



This singular Neotropical form is even more isolated than the Flamingo
and more difficult to place satisfactorily in a linear series. It
seems, however, that it is best arranged near the Anatidæ, as first
suggested by Mr. Parker[7], and that it may with least inconvenience
be constituted an aberrant family of the Order Anseres.

  [7] _Cf._ Proc. Zool. Soc. 1863, p. 511.

Besides the typical form _Palamedea_ (with one species found in Amazonia
and the interior of Brazil) the present family contains only one other
genus--_Chauna_--in which the head carries a feather-crest instead of
the long horny wattle of _Palamedea_. One species of _Chauna_ is met
with in Argentina, the only other known species (_C. derbiana_) being
confined to Colombia and Venezuela.

This majestic bird, called _Chajá_ in the vernacular, is common
throughout the Plata district, in marshes and on the open level country
abounding in water and succulent grasses, and ranges south to the
neighbourhood of Bahia Blanca. It is most abundant on the pampas south
of Buenos Ayres city, and on that vast expanse of perfectly level, green
country the bird is seen at its best; it is there an important feature
in the landscape; its vocal performances are doubly impressive on
account of the profound silence of nature, and its singularity--the
contrast between its aerial habit and ponderous structure--strikes one
more forcibly where the view is so unobstructed and the atmosphere so

The Crested Screamer, like most of the larger birds and mammals in every
part of the globe to which European emigration is attracted, is probably
doomed to rapid extermination. My observations of the bird, in that
portion of the pampas where it is most abundant, date back some years,
to a time when the inhabitants were few and mainly of Spanish race,
never the destroyers of bird-life. The conditions had become extremely
favourable to this species. It is partially aquatic in its habits; and
in desert places is usually found in marshes, wading in the shallow
water, and occasionally swimming to feed on the seeds and succulent
leaves of water-loving plants. After the old giant grasses of the
pampas had been eaten up by the cattle, and the sweet grasses of
Europe had taken their place, the Screamers took kindly to that new
food, preferring the clovers, and seemed as terrestrial in their
feeding-habits as Upland Geese. Their food was abundant, and they
were never persecuted by the natives. Their flesh is very dark, is
coarse-grained but good to eat, with a flavour resembling that of wild
duck, and there is a great deal of meat on a bird with a body larger
than that of a Swan. Yet no person ever thought of killing or eating the
Chajá; and the birds were permitted to increase to a marvellous extent.
It was a common thing a few years ago in the dry season to see them
congregated in thousands; and so little afraid of man were they that I
have often ridden through large scattered flocks without making the
birds take wing.

A curious thing about the Screamer is that it pairs for life, and yet is
one of the most social of birds. But if a large flock is closely looked
at, the birds are invariably seen methodically ranged in pairs. Another
curious thing is that, notwithstanding the formidable weapons they
possess (each wing being armed with two large spurs), they are extremely
pacific in temper. I have never been able to detect even the slightest
approach to a quarrel among them; yet it is hard to believe that they
do not fight sometimes, since weapons of offence are usually found
correlated with the disposition to use them. Captive birds, however, can
be made to fight; and I have known Gauchos take them for the pleasure of
witnessing their battles. They are very easily tamed, and in that state
seem to show greater docility and intelligence than any of our domestic
birds; and become so attached to their home that it is quite safe to
allow them to fly about at will. They associate, but do not quarrel,
with the poultry. They are quick to distinguish strangers from the
people of the house, showing considerable suspicion of them, and
sometimes raising a loud alarm at a stranger's approach. Towards dogs
and cats they are often unfriendly; and when breeding it is dangerous
for a strange person to approach the nest, as they will sometimes attack
him with the greatest fury.

The Screamer is a very heavy bird, and rises from the ground laboriously,
the wings, as in the case of the Swan, making a loud noise. Nevertheless,
it loves soaring, and will rise in an immense spiral until it wholly
disappears from sight in the zenith, even in the brightest weather;
and considering its great bulk and dark colour, the height it ultimately
attains must be very great. On sunny windless days, especially in winter
and spring, they often spend hours at a time in these sublime aerial
exercises, slowly floating round and round in vast circles, and singing
at intervals. How so heavy and comparatively short-winged a bird can
sustain itself for such long periods in the thin upper air to which it
rises has not yet been explained.

The voice is very powerful. When disturbed, or when the nest is
approached, both birds utter at intervals a loud alarm-cry, resembling
in sound the anger-cry of the Peacock, but twice as loud. At other times
its voice is exercised in a kind of singing performance, in which male
and female join, and which produces the effect of harmony. The male
begins, the female takes up her part, and then with marvellous
strength and spirit they pour forth a torrent of strangely-contrasted
sounds--some bassoon-like in their depth and volume, some like
drumbeats, and others, long, clear, and ringing. It is the loudest
animal-sound of the pampas, and its jubilant martial character strongly
affects the mind in that silent melancholy wilderness.

The Screamers sing all the year round, at all hours, both on the ground
and when soaring; when in pairs the two birds invariably sing together,
and when in flocks they sing in concert. At night they are heard about
nine o'clock in the evening, and again just before dawn. It is not
unusual, however, to hear them singing at other hours.

The nest is a large fabric placed among the low rushes and water-lilies,
and is sometimes seen floating on the water, away from its moorings. The
eggs are five, pointed at one end, pure white, and in size like the
eggs of the domestic goose. The young are clothed in yellow down like
goslings, and follow the parents about from the date of hatching.


The Anatidæ or Waterfowl are a well-known family of universal
distribution over the earth's surface. As shown in an article published
in the Zoological Society's 'Proceedings' for 1876[8], upwards of 60
species of this group of birds are found in the Neotropical Region, and
of these about 22 occur in the Argentine Republic. Amongst the Argentine
species are some of the finest and most ornamental of the whole family,
such as the Black-necked Swan, the Ashy-headed Goose, and the Chiloe
Wigeon--all well known from their introduction and acclimatization in

  [8] "A Revision of the Neotropical Anatidæ," by P. L. Sclater and O.
  Salvin, P. Z. S. 1876, p. 358.

It may be remarked that nearly all the Argentine members of this family
belong to Antarctic forms, and are specifically different from those met
with in North America.

Dr. Burmeister met with this fine Goose on the Rio Blanco in the
province of San Juan, within the confines of the Argentine Republic.
It is an inhabitant of the high Andes of Peru and Bolivia, and is also
found throughout the central provinces of Chili, descending to the
plains in the winter. Its native name is "_Piuquen_," and it is said to
be so abundant on a lagoon near the Portello Pass between Mendoza and
Santiago that the spot is called "Valle de los Piuquenes."

_Hab._ Chili and Argentina.

This bird is a northern form of the well-known "Upland Goose" of the
Falkland Islands and Southern Patagonia, from which it differs in the
male being completely barred across with black on the lower surface. It
was first described by Philippi and Landbeck from Chilian specimens, and
in 1872 recognized by Dr. Burmeister as found near the Sierra Tandil and
on the Rio Negro.

In April and May this Goose migrates northwards, along the eastern
coast, as far as the pampas of Buenos Ayres, the migration ending about
one hundred and fifty miles south of Buenos Ayres city. Further south
they are at this season of the year excessively abundant in suitable
localities. Their great camping-grounds are the valleys of the rivers
Negro and Colorado, where they are often so numerous as to denude the
low grounds of the tender winter clovers and grasses, and to cause
serious loss to the sheep-breeders. They also visit the cultivated
fields to devour the young wheat, and are intelligent enough to
distinguish between a real human enemy and the ragged men of straw,
miscalled scarecrows, set up by the farmers to frighten them. While
committing their depredations they are exceedingly wary and difficult to
shoot, but at night, when they congregate by the water-side, they give
the sportsman a better chance. I have succeeded in killing as many as
five at a shot by stalking them under cover of the darkness; and a more
deliciously flavoured game-bird than this Goose I have never tasted.

They are social birds, always going in large flocks, and are very
loquacious, the female having a deep _honking_ note, while the male
responds with a clear whistling, like the Sanderling's note

_Hab._ Patagonia, Southern Chili, and Southern Argentina.

This Patagonian Goose migrates northwards in winter, and appears on
the Rio Negro and in the Buenos-Ayrean pampas in May, usually in small
flocks, but sometimes as many as one or two hundred are seen together.
The extreme limit of their winter migration appears to be about
sixty miles south of Buenos Ayres city, on the plains near the river
Sanborombon; probably they have before now been driven from this
locality by the Duck-shooters, but it was formerly their favourite
rendezvous, where they collected in large numbers, though further north
scarcely one was ever seen.

Durnford tells us that this Goose is resident on Lake Colguape in the
territory of Chupat, and breeds there abundantly.

To my perhaps partial mind this species is preeminent for beauty among
the Swans, although it is considerably smaller than the bird of the
Old World, and does not, it must be admitted, comport itself so
majestically. In questions of this kind it is natural for every one to
be somewhat biassed in favour of the things of his own country; but it
will be readily admitted by all, I think, that the black-necked bird
is one of three species greatly surpassing all others of this genus in
beauty--the other two being, of course, the domesticated Swan of Europe
and the Australian Black Swan (perhaps the most graceful bird on the

This Swan is very abundant on the pampas of Buenos Ayres and in
Patagonia, and ranges south to the Magellan Straits and the Falklands.
As a rule they are seen in small flocks, but sometimes as many as two
or three hundred congregate together. They are heavy birds and rise
with difficulty, and fly rapidly and with great violence, like all
heavy-bodied short-winged species; but in no other very large bird with
which I am acquainted do the wings produce so loud a rushing sound. In
quiet places the beating of their wings can be heard distinctly when the
birds are no longer in sight, although, owing to their large size, the
eye can follow them very far. Gauchos sometimes capture them by suddenly
charging down the wind upon them, uttering loud shouts which greatly
terrify the birds, and when they attempt to rise with the wind they
only flap along the ground and are easily knocked over. A Gaucho of my
acquaintance one day caught three out of a flock of six in this way; but
a very strong wind favoured him, and the birds were at some distance
from the water, and allowed him to come near before making the sudden
charge. As a rule, they are seen on the water, and when on land they
keep very close to the margin.

According to Mr. Gibson, who has observed their breeding-habits, they
begin to nest in July--just after the winter solstice. The nest is
always placed among thick rushes growing in deep water, and the Swan
invariably swims to and from her nest. It is built up from the bottom
of the swamp, sometimes through four or five feet of water, and rises
a foot and a half above the surface. The top of the nest measures
about two feet across, with a slight hollow for the eggs, which are
cream-coloured and have a smooth glossy shell. The number varies from
three to five, and on one occasion six were found. Mr. Gibson has seen
the parent bird swimming from the nest with the young on her back.

Our figure of this species (Plate XVIII.) is taken from the specimen now
living in the Zoological Society's Gardens.

    _Female_ similar.

_Hab._ Patagonia, Chili, Argentina, and Paraguay.

This Swan is considerably smaller than the black-necked species,
and also inferior in beauty on account of its shorter neck. It is,
nevertheless, a very handsome bird, being entirely of a pure white
colour except the tips of the primaries, which are black. The beak and
legs are bright rosy red. In its habits, language, and flight it also
differs much from _Cygnus nigricollis_, and the country people call
it _Ganso_ (Goose), probably on account of its goose-like habit of
sometimes feeding away from the water, or because its flesh has the
flavour of Wild Goose. As a rule they go in small parties of five or six
individuals, but sometimes flocks numbering two or three hundred are
seen in the cold season. Their migrations are very irregular, and
sometimes they are excessively abundant in a district one year and
absent from it the next. When disturbed they utter a loud musical
trumpeting cry, in three notes, the last with a falling inflection; and
their wings being much longer proportionately than in the black-necked
species, they rise with greater ease and have a much freer and an almost
soundless flight.

Concerning their breeding-habits, Mr. Gibson observes that the nest is
usually placed on the ground at some distance from the water. It is
about a foot and a half high, made of mud and rushes; the hollow, which
is rather deep, is lined with dry grass.

The eggs are eight or nine in number; smooth, white, and rounder than
those of _Cygnus nigricollis_.

_Hab._ Mexico and South America.

This Duck, the well-known _Pato silvon_ (Whistling Duck) of the eastern
Argentine country, is found abundantly along the Plata and the great
streams flowing into it, and northwards to Paraguay. Along this great
waterway it is to some extent a migratory species, appearing in spring
in Buenos Ayres in very large numbers, to breed in the littoral marshes
and also on the pampas. They migrate principally by night, and do not
fly in long trains and phalanxes like other Ducks, but in a cloud; and
when they migrate in spring and autumn the shrill confused clangour of
their many voices is heard from the darkness overhead by dwellers in the
Argentine capital; for the Ducks, following the eastern shore of the
sea-like river, pass over that city on their journey. Northwards this
Duck extends to Central Brazil; from the northern half of the southern
continent and from Central America it is absent, but it reappears
in Mexico. Commenting on these facts Messrs. Sclater and Salvin
write:--"Singular as this distribution is, it is still more remarkable
when we consider that there appear to exist no tangible grounds for
separating the American bird from that called _D. major_ by Jerdon,
which ranges throughout the peninsula of India and is also found in

The Whistling Duck, in its chestnut and fulvous plumage, is a handsome
bird and somewhat singular in appearance, especially when seen in
a large body on the ground. When out of the water they crowd close
together, and when disturbed stand up craning their necks, looking
strangely tall on their long blue legs. While thus watching an intruder
they are silent, and the sudden ringing chorus of whistling voices into
which they burst at the moment of rising has a curious effect.

So extremely social are these Ducks that even when breeding they keep
together in large flocks. The nest is made of stems and leaves, on the
water among the reeds and aquatic plants; and sometimes large numbers
of nests are found close together, as in a gullery. The eggs are pure
white, and each bird lays, I believe, ten or twelve, but I am not sure
about the exact number; and I have so frequently found from twenty to
thirty eggs in a nest that I am pretty sure that it is a common thing
for two or three females to occupy one nest.

_Hab._ South America.

This Tree-Duck resembles that last described in size, form, and
maroon-red plumage, but is of a darker tint, and may also be easily
distinguished, even at a long distance, by its white face contrasted
with the velvety black of the head and neck. Compared with _Dendrocygna
fulva_ it is a rare species, being usually found in pairs in the Plata
district, although sometimes as many as half a dozen are seen together.
When taking wing it also whistles, but differently from the allied
species, having three long clear whistling notes, not unlike the
three-syllabled cry of the Sandpiper, only the notes are more prolonged.
Of its breeding-habits I know nothing.

    similar, but smaller.

_Hab._ Central and South America.

Everyone is familiar with this species in its domestic state, called in
the Argentine country _Pato creollo_ (Creole Duck); but the wild bird,
called _Pato real_, is little known, although a few stragglers are
seen as far south as Buenos Ayres, where I have met with eight or nine
examples. Concerning the distribution and habits of this species Messrs.
Sclater and Salvin write:--"The Muscovy Duck, so well known in a
domestic state nearly all over the world, is a native of the hottest
portion of tropical America. It is usually found in lowland swampy
districts; and where there are extensive forests it not unfrequently
abounds. During the day the birds remain in the forest-swamps; but
towards evening numbers may be seen sitting on the lower boughs of trees
standing on the margin of a clearing.

"Its extreme northern limit seems to be N. W. Mexico. Its southern range
extends to the upper Paraná and Tucuman. It is not uncommon in Paraguay,
according to Azara, although not found on the La Plata. It is to be seen
usually in pairs or singly, but also in flocks of twenty or thirty. It
always roosts in trees, usually resorting to the same trees night after
night. The nest, in which from ten to fourteen eggs are deposited,
is made in a hole or fork of a large tree at some elevation from the
ground. It seeks its food not only in the rivers, but on moonlight
nights resorts to the maize and corn-fields, and also plucks up the
roots of mandioca.

"The native habitat of the Muscovy Duck was known to some of the
earliest writers. The date of its introduction as a domesticated species
into Europe and elsewhere does not appear to have been recorded, but
doubtless dates back to soon after the Spanish conquests in America."

This small, obscurely coloured Duck extends from Southern Brazil over
the pampas of Buenos Ayres into Chili. Near Buenos Ayres it is scarce.

about twenty miles to the north-west of the city.

This Teal has an exceedingly wide distribution in America, being found
from California in the northern continent down to the Straits of
Magellan and the Falkland Islands in the south. Its fine, strongly
contrasted colours give it a very handsome appearance--the wings being
clear grey-blue, the body deep maroon-red, the feet vivid yellow, beak
black, and iris gold-colour. On the pampas it is common, and almost
invariably seen in pairs at all seasons. Many of the Teals are
quarrelsome in disposition; but this species, I think, exceeds them
all in pugnacity, and when two pairs come together the males almost
invariably begin fighting.

    with black; bill yellow; culmen and tip black; feet horn-colour:
    whole length 15·0 inches, wing 7·5, tail 7·5. _Female_ similar.

_Hab._ Argentina, Chili, and Patagonia.

In the southern part of the Argentine Republic this is one of the
commonest species, and is almost invariably found in every marsh,
stream, and pool of water on the pampas. It is resident, and usually
goes in flocks of from a dozen to thirty individuals. It has a rapid
flight, and is restless, lively, and extremely pugnacious in its habits.
When a flock is on the water the birds are perpetually quarrelling. They
are also highly inquisitive, and I have often shot them by first showing
myself to the flock, and then standing or sitting still, when they would
soon come wheeling about, flying in very close order. They quack and
chatter in a variety of tones, and the male has also a clear whistling
note in the love-season.

The nest of this Duck is always made at a distance from the water,
sometimes as far as one or two miles. It consists of a slight hollow in
the ground under a thistle-bush or tussock of long grass, and is lined
with dry grass and a great deal of down, which is increased in quantity
during incubation. The eggs are reddish cream-colour, and five is the
usual number laid; but I have also found nests with six and seven.

    wing-speculum not so bright.

_Hab._ Paraguay, Argentina, Patagonia, and Chili.

This prettily variegated blue-grey Teal with its strongly marked bill
is perhaps the most abundant of the genus in the Argentine Republic,
especially in the southern portion. It is resident, and unites in much
larger flocks than any other bird of this group in the country. Its
note when disturbed or flying is very peculiar, resembling in sound the
muffled stridulating of the mole-cricket. Durnford found it common and
breeding at Baradero.

    _Description._--Above earthy brown; head above and neck, which
    expands into a half-collar, together with the lesser wing-coverts,
    lower back, and tail above, black; scapulars pure chestnut; wings
    brownish black, with a large white blotch on the coverts of the

    wings with a white blotch as in the male; bill reddish; feet brown.

_Hab._ Paraguay and Argentina.

This beautiful Duck, for our first knowledge of which we are indebted to
Azara, is rather scarce in collections. Azara described the two somewhat
dissimilar sexes under different names, the male being his _Pato collar
negro_, and the female his _Pato ceja blanca_.

In the neighbourhood of Buenos Ayres the Ring-necked Teal is strictly
migratory, and in the month of October appears in small flocks in the
marshes along the river; but in the interior of the country it is seldom
met with. They are extremely active birds, constantly flying about from
place to place both by day and night; and in the love-season, when they
alight in a pool of water, the males immediately engage in a spirited
combat. While flying they utter a peculiar jarring sound, and
occasionally a quacking note, rapidly repeated and sounding like a
strange laugh; but on the water, especially in the evening, the male
emits a long inflected note, plaintive and exquisitely pure in sound--a
more melodious note it would be difficult to find even among the

    _Description._--Above brown; head more rufous; lower back, tail, and
    lesser wing-coverts black; wings brownish black; outer webs of the
    inner primaries and the secondaries shining bronzy green; broad tips
    of the outer secondaries white, divided from the green colour by
    a black band: beneath paler, washed on the breast with rusty red;
    throat whitish; belly slightly banded with brown; bill blackish;
    feet red: whole length 15·5 inches, wing 7·0, tail 3·3.

_Hab._ South America.

This richly coloured Teal, which is widely extended in South America
from Guiana down to the Straits of Magellan, is usually met with in
pairs near Buenos Ayres, although as many as five or six are sometimes
seen together. In habits it is a tree duck, preferring water-courses in
the neighbourhood of woods, and is frequently seen perched on horizontal
branches. The flight is slow and with the wings very much depressed, as
in a duck about to alight on the water; and the beautiful blue, green,
and white speculum is thus rendered very conspicuous. The note of the
male in the love-season is a long plaintive whistle, singularly pure and
sweet in sound, and heard usually in the evening.

It is a rather curious coincidence that the vernacular name of this
Teal in La Plata should be _Pato Portugues_, which means, as things are
understood in that region, Brazilian Duck.

    wings brown, with a large speculum of bronzy black, distinctly
    margined above and below with buff: beneath, throat dirty white,
    sparingly spotted with black; breast, flanks, and crissum tinged
    with rufous, the feathers with black centres; belly white, in the
    lower portion slightly varied with brown; bill black, at the base
    yellow; feet plumbeous: whole length 19·0 inches, wing 9·7, tail
    5·5. _Female_ similar.

_Hab._ Southern Brazil, Peru, Paraguay, Argentina, Chili, and Patagonia.

The Brown Pintail is the commonest Duck in the Argentine Republic, and
unites in the largest flocks. It is also, according to Philippi and
Landbeck, the commonest species in Chili. It ranges from South Brazil
and Peru to the Magellan Straits and the Falklands; but is probably most
abundant in the Plata district and in North Patagonia. In the autumn it
sometimes visits the pampas in immense numbers, to feed on the seed of
the giant thistle (_Carduus mariana_); and on these occasions I have
known as many as sixty killed at one shot. The birds, however, soon
become wary when feeding on the open plains in large flocks, and it then
becomes impossible to approach them without a trained horse. The Ducks
pay no attention to horses and cattle browsing near them; and the
trained animal, with the gunner concealing his gun and person behind it,
feeds quietly along, and gradually approaches the flock until within
range. In the valley of the Rio Negro, in Patagonia, the Pintails
sometimes cause serious damage to the farmers, coming up in clouds from
the river by night to devour the ripe grain.

In favourable seasons the Pintail is a resident; but like the
marsh-gulls, pigeons, the American golden plover, and all birds that
live and move in immense bodies, it travels often and far in search of
food or water. A season of scarcity will quickly cause them to disappear
from the pampas; and sometimes, after an absence of several months, a
day's rain will end with the familiar sound of their cry and the sight
of their long trains winging their way across the darkening heavens.

Their nest is made on the ground, under the grass or thistles, at a
distance from the water, and is plentifully lined with down plucked
from the bosom of the sitting bird. The eggs are seven or eight in
number and of a deep cream-colour.

    fawn-colour; wings dark slaty black; broad speculum bronzy green,
    margined above and below by a fawn-coloured band, the lower band
    with an interior black margin; edgings of the external secondaries

_Hab._ South America.

The Bahama Duck, as it is commonly called, though it is very doubtful
whether it really occurs in the Bahama Islands, is found throughout
South America from British Guiana to Patagonia; and Burmeister says
that it is spread over the whole of Brazil, and that it is nearly the
commonest species of Duck in that country.

On the pampas of Buenos Ayres this Duck is not a common bird. It is
usually seen in pairs, or, on rare occasions, three or four together.

_Hab._ Paraguay, Argentina, Chili, and Patagonia.

The Chiloe Wigeon, as this Duck has been usually called since its
introduction and acclimatization in England, is the only species of the
genus found in South America, and is most abundant on the pampas,
where it is called by the country people _Pato picaso_ or _Pato overo_
(piebald duck), or _Chiriví_ from its cry. It is a very handsome bird;
the upper plumage variegated with black, white, and grey; forehead,
speculum, and under surface white; head and neck dark glossy green. It
is resident, and is usually seen in small flocks of from a dozen to
twenty birds, but sometimes as many as one or two hundred congregate
together. They are wary and loquacious, strong on the wing, and
frequently engage in a peculiar kind of aerial pastime. A small flock
will rise to a vast height, often until they seem mere specks on the
sky, or disappear from sight altogether; and at that great altitude they
continue hovering or flying, sometimes keeping very nearly in the same
place for an hour or more, alternately separating and closing, and every
time they close they slap each other on the wing so smartly that the
sound may be heard distinctly even when the birds are no longer visible.
While flying or swimming about they constantly utter their far-sounding
cry--three or four long, clear, whistling notes, followed by another
uttered with great emphasis and concluding with a kind of flourish.

The nest is made amongst the rushes in the marshes, and the eggs are
pure white and eight or nine in number.

_Hab._ Argentina, Patagonia, and Chili.

There is but one Shoveller Duck in South America, the present species,
which is confined to the southern part of the continent, from Paraguay
to Patagonia, and is familiar to sportsmen in the Plata as the Red Duck,
or _Espatula_. It is seldom met with in flocks of more than twenty or
thirty individuals, and a large number of birds appear to pair for life,
as they are usually seen in pairs at all seasons of the year. In the
autumn and winter months I have sometimes observed small flocks composed
of males only, but these were perhaps young birds not yet paired. They
feed in shallow water, where by plunging the head down they can reach
the mud at the bottom; and when several are seen thus engaged, all with
their heads and necks immersed, they look curiously like headless ducks
floating on the water. When disturbed or flying the male emits a low
sputtering sound, and this is its only language. They are resident and
the least wary of ducks; never engage, like other species, in real or
mock combats; and their flight is rapid and violent, the wings beating

    wings white with black ends, and covered with the black coverts,
    having a white speculum; primaries greyish white, the four outer
    ones on their outer webs and all on their extremities black; whole

    rosy red, enlarged at the base; feet yellowish: whole length 19·0
    inches, wing 9·4, tail 2·8. _Female._ Above brown, bend of wing and

_Hab._ Paraguay, Argentina, Chili, and Patagonia.

The Rosy-billed Duck, usually called "Black Duck" in the Plata, inhabits
the Argentine country from Paraguay to Patagonia, and also occurs in
Uruguay and Chili, but does not extend to Brazil.

A peculiar interest attaches to this species owing to the fact that it
is the only freshwater Duck in the subfamily Fuligulinæ, in which it
is classed. With the exception of the Loggerhead Duck (_Tachyeres
cinereus_), found in the Falklands and the Magellan Straits, all the
other sea-ducks of this division inhabit North and Central America; so
that the Rosy-bill appears to have separated itself widely from its
nearest relations geographically as well as in habits. In appearance it
is a fine bird, the black plumage being frosted on the upper parts with
white in a very delicate manner, while the rosy bill and large carmine
caruncle and golden red iris contrast beautifully with the glossy purple
head and neck. The speculum is white, the legs bright yellow. The
plumage of the female is brown.

In marshy places on the pampas the Rosy-billed Duck is very abundant,
and they sometimes congregate in very large flocks. They obtain their
food from floating weeds in the water, and are never seen, like the
Pintails and other kinds, feeding on the dry land. They rise heavily,
the wings being comparatively small, and have a rapid, straight, violent
flight; they are nevertheless able to perform long journeys and travel
in long lines and at a considerable elevation. Their only language is a
deep, hoarse, prolonged, raven-like note, uttered by the male in the
love-season. The nest is made on swampy ground near the water, of dry
rushes, and is, for a duck, a deep well-made structure; the eggs are
oval in form, cream-coloured, and twelve in number.

_Hab._ Central Peru, Chili, and Argentina.

This Lake-Duck ranges from Central Peru and the north Argentine
provinces to Patagonia in the south, but is in no place a very common
bird. It inhabits interior lakes and streams, living almost as much in
the water as a Grebe, which in habits it resembles, remaining motionless
when disturbed, but gradually sinking lower in the water, and diving,
when only the head and neck are visible above the surface.

_Hab._ West Indies and South America.

This Lake-Duck, which has an extensive range over the northern part of
South America, was obtained by Mr. Lee in Entrerios, and by Mr. Barrows
in the streams of the Pampas. Mr. Barrows found it associated with
Rolland's Grebe, Coots, and Gallinules, usually in small parties of from
three to six individuals.



The great and useful Order of Pigeons is generally diffused over the
earth's surface, although most abundant within the tropics, and not met
with in high Arctic or Antarctic latitudes. In the Neotropical Region
from 60 to 70 species are found, and among these, although none of
them can rival the Fruit-Pigeons of the Eastern Tropics, are some of
remarkable beauty and grace. These brilliantly-coloured species are,
however, mostly from the northern portion of the Neotropical Region. The
Columbæ of the Argentine Republic are in general modestly clad and fewer
in number, only eight Pigeons being as yet included in the Argentine

The Picazuro or common Wood-Pigeon of the Argentine Republic is of about
the size of the domestic Pigeon, but has longer wings, and differs
greatly in colour and markings. In summer it inhabits woods, and is seen
in pairs or small parties, but in winter unites in flocks of from twenty
to one or two hundred individuals, and roams much over the open country.
It is a wary bird, and when feeding walks on the ground in a slow and
somewhat stately manner. In spring, its song resounds in the woods,
and, when heard for the first time, fills the listener with wonder, so
strangely human-like in tone are its long mournful notes. The notes
are five, the last one long with a falling inflection, and profoundly
sorrowful. The nest is a platform structure, frequently placed on a
broad horizontal branch; the eggs are two, and closely resemble those
of the common Rock-Pigeon of Europe.

_Hab._ Peru, Bolivia, Western Argentina, and Patagonia.

This Pigeon has a general resemblance to the Picazuro, but may be at
once distinguished by its spotted back and wings. It ranges from South
Peru through Bolivia and Western Argentina into Patagonia, where it
appears to be a resident. In winter, the valley of the Rio Negro is
visited by it in immense flocks, which are a great plague to the
farmers, as they descend in clouds on the fields, and devour the wheat
before it has time to sprout. While watching crowds of these birds
feeding on the ground, I noticed that their manner was in striking
contrast to that of the _C. picazuro_, which has slow and dignified
motions; for it hurried about, and snatched up its food with such
rapidity that the most animated motions of other birds that feed in
flocks on the ground seemed languid by comparison. This excessively
lively habit is, no doubt, directly caused by the conditions of life;
the sterile soil and scanty vegetation of the region it inhabits require
in a species going in large bodies, and subsisting exclusively on fallen
seed, a greater activity than is necessary in the rich fertile region
further north.

Its song is composed of notes equal in length and number to that of the
Picazuro, but its voice is exceedingly hoarse, like that of the European

The great body of these birds retire, on the approach of summer,
from the Rio Negro valley, a few only remaining to breed. Their
nesting-habits and eggs are like those of the Picazuro.

    white margins; tail plumbeous, broadly ended with white, and crossed
    by a subapical black band; middle rectrices like the back: beneath
    pale vinaceous, brighter on the breast, and whiter on the throat;
    bill black; feet yellow: whole length 9·0 inches, wing 5·5, tail
    3·5. _Female_ similar.

_Hab._ South America, from the Amazons to Chili and Buenos Ayres.

This is the commonest species of the Pigeon tribe in the Argentine
country, and is known to every one as the _Torcasa_, probably a
corruption of _Tortola_, Turtle-Dove. In autumn they often congregate
in very large flocks, and are sometimes observed migrating, flock
succeeding flock, all travelling in a northerly direction, and
continuing to pass for several consecutive days. But these autumnal
migrations are not witnessed every year, nor have I seen any
return-migration in spring; while the usual autumn and winter movements
are very irregular, and apparently depend altogether on the supply of
food. When the giant thistle has covered the plains in summer incredible
numbers of Torcasas appear later in the season, and usually spend the
winter on the plains, congregating every evening in countless myriads
wherever there are trees enough to form a suitable roosting-place.

On bright warm days in August, the sweet and sorrowful sob-like song
of this Dove, composed of five notes, is heard from every grove--a
pleasing, soft, murmuring sound, which causes one to experience by
anticipation the languid summer feeling in his veins.

The nest, as in other Pigeons, is a simple platform of slender sticks;
the eggs are oval, white, and two in number. The birds appear to breed
by preference near a human habitation, and do so probably for the sake
of the protection afforded them; for the Chimango and other birds of
prey destroy their eggs and young to a large extent.

One summer a Torcasa laid an egg in the nest of one of my Pigeons,
built on the large horizontal branch of a tree at some distance from
the dove-cote. The egg was hatched, and the young bird feared by its
foster-parents; and when able to fly it took up its abode along with the
other Pigeons. The following spring it began to separate itself from its
companions, and would fly to the porch, and sit there cooing by the hour
every day. At length it went away to the plantation, having, I believe,
found a mate, and we saw no more of it.

This Dove is widely diffused in Western South America from Ecuador to
Chili. Dr. Burmeister tells us that it is found in the high valleys
of the Cordilleras on the Argentine side, from 6000 to 12,000 feet in
altitude, and along with _Phrygilus fruticeti_ is one of the birds seen
at the greatest altitudes by the traveller over the passes of the Andes.
One of Dr. Burmeister's specimens is in the collection of Messrs. Salvin
and Godman.

  +Metriopelia aymara+, _Scl. et Salv. Nomencl._ p. 132. +Columbina
      aurisquamata+, _Leybold, Leopoldina_, viii. p. 53 (1873).

    _Description._--Above pale brown; wings and tail black; wing-coverts
    like the back; some of the middle coverts with bright golden apical
    spots: beneath pale vinaceous; throat whitish; middle of belly and
    crissum pale cinnamomeous; bill black; feet yellow: whole length
    7·0 inches, wing 4·5, tail 2·5. _Female_ similar.

_Hab._ Peru, Bolivia, and N.W. Argentina.

Dr. Leybold's collector obtained examples of this Dove in 1863, at Los
Paramillos, a rocky district near Uspallata, on the Argentine slope of
the Chilian Andes. Some of these specimens are in the collection of
Messrs. Salvin and Godman.

The species is easily recognizable by the bright golden wing-spots.

      (Buenos Ayres); _Gibson, Ibis_, 1880, p. 7 (Buenos Ayres);
      _Barrows, Auk_, 1884, p. 275 (Entrerios).

    _Description._--Above brownish cinereous; head and neck plumbeous;
    wing-feathers black; coverts and outer secondaries like the back,
    but bordered with white on their outer edges, and with a band of
    bright blue across the tips of the lesser coverts; tail white,
    middle rectrices like the back, lateral rectrices more or less
    bordered with cinereous on the outer web, except the outer pair,
    which are pure white: beneath pale vinaceous; throat, lower belly,
    and crissum white; under wing-coverts black; bill black; feet
    yellow: whole length 6·5 inches, wing 3·5, tail 2·0. _Female_
    similar, but duller; above nearly uniform brown.

_Hab._ Brazil, Paraguay, Argentina, and Chili.

This species, the smallest of our Doves, is common everywhere in the
Plata district, where it is called _Tortolita_ (Little Turtle-Dove),
Azara's name _Picui_ not being known to our countrymen.

It is usually seen with its mate, for many individuals seem to pair for
life; but sometimes a dozen or twenty individuals unite in one flock. It
is resident, comes a great deal about houses, and is familiar with man,
and lively in its habits. It sings a great deal in summer, and even on
warm days in winter; but its tones are wanting in the wild pathos which
gives a charm to the melody of some of our larger species, the song
consisting of a succession of long, rather loud, and somewhat monotonous
notes, pleasant to hear, like most bird-music, but nothing more.

The nest is the usual slight structure of sticks; the eggs two, oval,
and white. They breed twice, and sometimes three times, in one season,
the last brood being hatched as late as April or even May.



  +Chamæpelia talpacoti+, _Scl. et Salv. Nomencl._ p. 133; _White, P.

    black; coverts and outer secondaries like the back, but the latter
    spotted with elongated black bands on the outer webs; tail black,
    tipped with vinaceous; middle rectrices like the back: beneath
    similar, but not so dark, and whitish on the throat; bill black;
    feet yellow: whole length 6·5 inches, wing 3·5, tail 2·5. _Female_
    similar, but much duller and more brownish.

_Hab._ Brazil, Paraguay, and Northern Argentina.

The Talpacoti or Chocolate Dove is an inhabitant of Brazil, Bolivia, and
Paraguay. In Argentina it occurs only on the northern frontiers, and was
met with by White at Oran, in the province of Salta, in the month of
November:--"These pretty chocolate-coloured Doves," he tells us, "fly
in pairs, and at this date were found constructing their nests in the
orange-groves. They are sometimes seen on the ground busily in quest of
seeds, but are very wild and not at all common."

White also obtained specimens of this Dove at Concepcion in Misiones.

    _Description._--Above greyish brown; head and nape plumbeous; back

    blackish, broadly tipped with white; central rectrices like the
    back: beneath pale vinaceous; middle of throat, belly, and crissum
    white; under surface of wings bright chestnut; bill black; feet
    yellowish: whole length 10·0 inches, wing 5·7, tail 4·8. _Female_

_Hab._ Argentine Republic.

This Dove, which is a southern form of a widely distributed group of
species of the genus _Engyptila_, formerly called _Leptoptila_, inhabits
the woods of the Plata district, and never, like other Pigeons, seeks
the open country to feed. It is solitary, although, where many birds
live in close proximity, three or four may be sometimes seen in company.
It spends a great deal of time on the ground, where it walks about
under the trees rather briskly, searching for seeds and berries. Their
song is a single uninflected and rather melodious note, which the bird
repeats at short intervals, especially in the evening during the warm
season. Where the birds are abundant the wood, just before sunset,
becomes vocal with their curious far-sounding notes; and as this evening
song is heard as long as the genial weather lasts, it is probably not
related to the sexual instinct. The nest is a simple platform; the eggs
are two and white, but more spherical in shape than those of most other



Of the great Order of Gallinaceous Birds, so useful to mankind,
two forms only are found in South America--the Toothed Partridges
(_Odontophorinæ_) and the Curassows (_Cracidæ_). No member of the former
group has as yet been ascertained to occur in Argentina; and of the
Curassow family (one of the most characteristic types of Neotropical
forest-life) only four species are with certainty known to be found
within our limits out of a total of some fifty known species. But the
Cracidæ are essentially tree-birds, and can only be looked for in

    _Description._--Black; lower belly and tips of tail-feathers white;
    lores naked; cere and bill yellow; feet flesh-colour: whole length
    32·0 inches, wing 14·0, tail 14·0. _Female_: above black, with buffy

    breast more or less barred with black; abdomen ochraceous; tail
    black, with buffy-white bars and tips.

_Hab._ Paraguay and N. Argentina.

Azara described both sexes of this Curassow under the name of "El Mitu"
(Apunt. iii. p. 83), but, along with other authors, confounded it with
the Crested Curassow of Guiana (_Crax alector_). In Paraguay it is said
to be numerous, but in Argentina only occurs on the northern and eastern
frontiers (in Tucuman and Misiones), where it frequents the forests.

    length 25·0 inches, wing 11·5, tail 12·0. _Female_ similar.

_Hab._ Paraguay, Northern Argentina, and Bolivia.

This Guan was first made known to us as an inhabitant of Paraguay by
Azara, who described it in his 'Apuntamientos'[9] under the name of
"El Yacúhú" or "_Pavo del Monte_" (Wood-Turkey) of the Spaniards. The
examination of skins of it obtained by Capt. J. T. Page, of the U.S.
Navy, during his expedition up the Rio Paraguay and Rio Vermejo, enabled
Messrs. Salvin and Sclater to make this identification.

  [9] Vol. iii. p. 72, no. 335.

In Entrerios, Mr. Barrows tells us, this species is limited to the
borders and islands of the River Uruguay, where in heavy growths of
timber it is not uncommon, though rarely seen. Here it builds a large
nest in the trees and lays white eggs.

It is probable that the Guan of Tucuman called by Dr. Burmeister
_Penelope boliviana_ and that of Catamarca referred by White to _P.
pileata_ likewise belong to this species.

Dr. Burmeister tells us that this Guan, which is widely extended in
South America, occurs in the forests of Tucuman.

    breast slightly spotted with greyish; under wing-coverts, flanks,
    and crissum chestnut; tail bronzy green, five outer rectrices
    broadly tipped with chestnut; bill yellowish; feet pale hazel: whole
    length 22·0 inches, wing 9·8, tail 10·3. _Female_ similar.

_Hab._ Paraguay and Northern Argentina.

For our first knowledge of this Guan we are also indebted to Azara, who
described it in his 'Apuntamientos' (iii. p. 77) under the name _Yacú
caraguata_, as found in the forests of Paraguay. Thence it extends
into the wooded districts of the northern provinces of the Argentine
Republic, where it was obtained by Dr. Burmeister in Tucuman and by
Capt. Page's expedition on the Rio Paraná and Rio Vermejo. It is
probable also that the Guan met with by White near Salta, and referred
by him to _O. guttata_, was really of the present species.



The Rallidæ are well represented in the Argentine Republic, eight Rails
and Crakes, two Waterhens, and three Coots being met with within
its limits, and it is highly probable that the list will be further
augmented as discovery advances.

The presence of three species of Coots, all apparently in abundance, is
a somewhat special peculiarity of the Argentine Ornis. Most of the other
Argentine Rallidæ have an extended range.

_Hab._ South America.

The Spotted Rail, which has a wide distribution in South America, occurs
as far south as Buenos Ayres. Our figure is taken from an example of
this species obtained by Mr. F. Withington in September 1885 in the
Lomas de Zamora. Concerning its nesting-habits he sends the following
note:--"It breeds amongst the reeds, and its nest is placed about 18
inches from the water. To reach it the birds collect a heap of reeds,
grass, and other materials, and alongside form an inclined platform that
answers the purpose of a staircase, by which the birds ascend or descend
with ease. The usual clutch of eggs is seven, but I have taken fifteen
from one nest, all good. These, of course, could not have been laid by
one bird."

This Rail is a small southern representative of the well-known Virginian
Rail of the U.S. It is stated to be "rather common" at Carhué by Mr.
Barrows, and Mr. Withington has recently sent us specimens from the
Lomas de Zamora.

_Hab._ Southern Brazil, Peru, Paraguay, Argentina, Chili, and Patagonia.

This Rail differs from the other species in its beak, which is very long
and curved, as in the Painted Snipe (_Rhynchæa_), and has three strongly
contrasted colours--dark green, bright blue, and scarlet at the base.
The blue and red tints become very vivid in the love-season. Without
being anywhere abundant, the Black Rail is found throughout the Plata
Region in every place where reeds and rushes grow. In the marshes
along the Plata they are met with quite as frequently in winter as in
summer; this fact surprised me greatly, since I know this species to
be migratory, their unmistakable cries being heard overhead every
night in spring and autumn, when they are performing their distant
journeys. Probably all the birds frequenting the inland marshes on the
south-western pampas migrate north in winter, and all those inhabiting
the Plata marshes and the Atlantic sea-board, where there is abundant
shelter and a higher temperature, remain all the year. On the Rio Negro
of Patagonia I found the Black Rail a resident, but the winter of that
district is singularly mild; moreover, the wide expanse of waterless
country lying between the Rio Negro and the moist pampa region would
make an annual migration from the former place difficult to such a
feeble flier. Of this instinct we know at least that it is hereditary;
and it becomes hard to believe that from every one of the reed-beds
distributed over the vast country inhabited by this species a little
contingent of migrants is drawn away annually to winter elsewhere,
leaving a larger number behind. Such a difference of habit cannot exist
among individuals of a species in one locality; but differences in the
migratory as in other instincts, great as this, are found in _races_
inhabiting widely separated districts.

It is difficult to flush the Black Rail; it rises in a weak fluttering
manner, the legs dangling down, and, after flying thirty or forty yards,
drops again into the reeds. Its language is curious: when alarmed,
the bird repeats, at short intervals, a note almost painful from its
excessive sharpness, and utters it standing on a low branch or other
elevation, but well masked by reeds and bushes, and incessantly bobbing
its head, jerking its tail, and briskly turning from side to side. It
has, at such times, a very interesting appearance, while the long beak,
brilliant with the nuptial colouring, the bright-red eye and vermilion
legs, admirably contrasting with the fine deep slate plumage, give it
considerable claims to beauty. At other times it has a hollow call-note
with a puzzling ventriloquism in the sound, which is sometimes repeated
at short intervals for an hour. While uttering it the bird stands, as
usual, on a slight eminence, but drawn up in a listless attitude and
without any of its nods and jerks and other frisky gestures. It has also
a kind of song, which sounds not unlike the braying of a donkey; hence
the vernacular name _Burrito_ (little ass) by which the bird is known in
the Plata. This song is heard both day and night, and is a confused
performance, uttered without pause, and composed of several long shrill
notes, modulated and mingled with others, hollow and booming. These
notes can be heard a thousand yards away; but, far or near, they always
sound remote.

    _Description._--Above olive-green; neck red; front cinereous; rump
    and tail black: beneath, throat white, breast and neck cinereous;
    abdomen rosy red, lower belly and thighs grey; flanks and crissum
    black; under wing-coverts rufous, with black cross bars; bill
    yellow; feet red: whole length 19·0 inches, wing 8·5, tail 3·3.
    _Female_ similar.

_Hab._ Brazil, Paraguay, and Argentina.

"Ypecaha" is the Guarani name, preserved by Azara, of this highly
interesting species; by the Spanish it is called "_Gallineta_," from
its supposed resemblance to a fowl. Without any brilliant tints, there
is yet something so pleasing to the eye in the various hues of its
plumage--light brown and drab colour, grey, buff, and black--all these
colours so harmoniously disposed, the effect heightened by the long
straight yellow beak, golden-red eye, and vermilion legs, that I do not
know a handsomer waterfowl.

These Rails are found as far south as the thirty-fifth parallel of
latitude, and are abundant along the marshy borders of the Plata,
frequenting the vast reed-beds and forests of water-loving _Erythrina
crista-galli_. Where they are never persecuted they are bold pugnacious
birds, coming out of the reeds by day and attacking the domestic poultry
about the houses and even in the streets of the villages situated on the
borders of their marshy haunts. But when compelled to place man on the
list of their enemies, it is a difficult matter to get a sight of one;
for, like all birds that rise laboriously, they are vigilant to excess,
and keep themselves so well concealed that the sportsman may pass
through their haunts every day of the year, and the Ypecaha still be
to him no more than a "wandering voice." But even persecution does not
entirely obliterate a certain inquisitive boldness which characterizes
them. Usually they roam singly in quest of food, but have reunions
in the evening and occasionally during the day, especially in gloomy
weather. On misty days they often wander to a distance from the covert,
walking with an easy, somewhat stately grace, jerking the tail at every
stride, and running with a velocity no man can equal. Where there are
woods they usually fly, when disturbed, into a tree; and it is in
connexion with this habit that the Ypecaha sometimes makes a curious
mistake in places where it has not been much shot at. One day, while
pushing my way through a dense growth of rushes, I saw two Ypecahas not
fifteen yards from me, on the horizontal branch of a tree, to which
they had evidently flown for safety. I was anxious to secure them,
but surprised at their temerity; and wishing to find out its cause, I
approached them still nearer, and then stood for some time observing
them. It was easy to see that they fancied themselves quite safe from
me while off the ground. In the most unconcerned manner they continued
strutting up and down along the branch, jerking their tails, and turning
about this way and that, as if to tantalize their baffled enemy by
ostentatiously displaying their graces.

When surprised on the open ground the Ypecaha lies close, like a
Tinamou, refusing to rise until almost trodden upon. It springs up with
a loud-sounding whirr, rushes violently through the air till, gaining
the reeds, it glides a few yards and then drops: its flight is thus
precisely like that of the Tinamou, and is more sounding and violent
than that of the Grouse or Partridge. On spying an intruder it
immediately utters a powerful cry, in strength and intonation not unlike
that of the Pea-fowl. This note of alarm is answered by other birds at
a distance as they hastily advance to the spot where the warning was
sounded. The cry is repeated at irregular intervals, first on one
side, then on the other, as the birds change their position to dog
the intruder's steps and inspect him from the reeds. I have surprised
parties of them in an open space, and shot one or more; but no sooner
had the survivors gained their refuge than they turned about to watch
and follow me, sounding their powerful alarm the whole time. I have
frequently been followed half a mile through the rushes by them, and by
lying close and mimicking their cries have always succeeded in drawing
them about me.

But the Ypecaha's loudest notes of alarm are weak compared with the
cries he utters at other times, when, untroubled with a strange
presence, he pours out his soul in screams and shrieks that amaze the
listener with their unparalleled power. These screams, in all their
changes and modulations, have a resemblance to the human voice, but of
the human voice exerted to its utmost pitch, and expressive of agony,
frenzy, and despair. A long piercing shriek, astonishing for its
strength and vehemence, is succeeded by a lower note, as if in the first
one the creature had well-nigh exhausted itself. The double scream is
repeated several times; then follow other sounds, resembling, as they
rise and fall, half-suppressed cries of pain and moans of anguish.
Suddenly the unearthly shrieks are renewed in all their power. This is
kept up for some time, several birds screaming in concert; it is renewed
at intervals throughout the day, and again at set of sun, when the
woods and marshes resound with the extravagant uproar. I have said that
several birds unite in screaming; this is invariably the case. I have
enjoyed the rare pleasure of witnessing the birds at such times; and the
screams then seem a fit accompaniment to their disordered gestures and

A dozen or twenty birds have their place of reunion on a small area of
smooth clean ground surrounded by reeds; and by lying well concealed and
exercising some patience, one is enabled to watch their proceedings.
First one bird is heard to utter a loud metallic-sounding note, three
times repeated, and somewhat like the call of the Guinea-fowl. It
issues from the reeds, and is a note of invitation quickly responded
to by other birds on every hand as they all hurriedly repair to the
customary spot. In a few moments, and almost simultaneously, the birds
appear, emerging from the reeds and running into the open space, where
they all immediately whirl about and begin the exhibition.

Whilst screaming they rush from side to side as if possessed with
frenzy, the wings spread and agitated, the beak wide open and raised
vertically. I never observed them fight or manifest anger towards each
other during these performances; and, knowing the pugnacious spirit of
the Ypecahas, and how ready they are to seek a quarrel with birds of
other species, this at first surprised me, for I was then under the
mistaken impression that these gatherings were in some way related to
the sexual instinct.

Whilst watching them I also remarked another circumstance. When
concealing myself amongst the rushes I have been compelled to place
myself so disadvantageously, owing to the wet ground, that any single
bird straying accidentally into the open space would have discovered
my presence immediately; yet the birds have entered and finished their
performance without seeing me, so carried away are they by the emotion
that possesses them during these moments. But no sooner has the wild
chorus ended than, aware of my presence, they have fled precipitately
into the reeds.

We frequently speak of our familiarity with the habits of the species we
have long and carefully observed in a state of nature; yet the knowledge
so gained must necessarily be exceedingly imperfect, for with many shy
vigilant birds it is next to impossible to see them without being seen;
and no bird, conscious of being watched, will act unconstrainedly any
more than a human being with clouded reputation will comport himself
naturally with the eyes of a detective on him. While we are observing
the bird, the bird watches us: of all its curious doings when we are out
of its sight and mind we see nothing. The only way to learn the habits
of a species like the Ypecaha--wary, intelligent, and passing its life
behind a screen of rushes--is to domesticate it; for although in this
state some instincts are blunted and others remain in abeyance, they are
not obliterated. It might surprise some that I speak of the Ypecaha as
an intelligent bird, since it is a member of the "stupid family," as
Professor Parker has called the Rails; but in spite of the very profound
admiration I feel for that illustrious anatomist, I believe he is wrong
about these birds: there is, to my mind, very much more stupidity in the
Auserine and Limicoline families, while the Ypecaha has always seemed to
me a singularly intelligent bird.

Fortunately Azara was able to give an account of one of these birds
in a domestic state, which shows that it makes a very sprightly and
entertaining, although a mischievous pet. It was taken young and allowed
to run about at liberty with the poultry at the house of a village
doctor in Paraguay. When full-grown it was very domineering, and became
the tyrant of the poultry-yard. Occasionally a cock had the courage to
face it, and then a singular combat would ensue: the Ypecaha, moving
with astonishing rapidity, putting its head low down, would charge, and,
thrusting its head between the cock's legs, fling him instantly on his
back, then rain a shower of blows on his breast before he could rise. It
was fond of eggs, and always knew when a hen went off to lay, cautiously
following her to the nest and then concealing itself at some distance to
wait. As soon as the egg was dropped it would run, pick it up with its
beak, and carry it away to a safe distance, and then, breaking a hole
in the shell at one end, suck out the contents without spilling a drop.
Sometimes, when the hen remained too long on the nest, it would lose
its temper and, driving her off, pursue her with the greatest animosity
about the grounds, administering correction with its sharp beak. Not
satisfied with devouring all the eggs laid by the doctor's fowls, it
visited all the neighbours' houses, doing so much damage that at length
the poor doctor, afraid perhaps that his practice would suffer, had the
troublesome bird put to death.

This Ypecaha would never allow any one to touch it, but it would come
into the house and search through all the rooms for thimbles, scissors,
and other small metal objects, and these it would carry away to conceal
them among the weeds or else bury them in the mud. It was also a good
mouser, and after killing a mouse with a blow from its beak would
swallow it entire.

occurs in the Northern Provinces of the Argentine Republic, where it was
met with by Dr. Burmeister in Tucuman.

    lighter: whole length 5·5 inches.

_Hab._ Chili and Argentina.

In 1876 Durnford obtained a specimen of this Crake from the river-scrub
near Belgrano in the province of Buenos Ayres, and described and figured
it in 'The Ibis' under the MS. name "_spiloptera_," which had been given
by Dr. Burmeister to an example of the same bird in the Buenos Ayres

Dr. Burmeister has, however, recently ascertained that the appellation
which he proposed for this species must give way to that of _salinasi_,
under which title it was described in 1857 by Dr. Philippi of Santiago.

_Porzana salinasi_, as we must therefore call it, is most nearly allied
to _P. spilonota_ of the Galapagos (_cf._ Scl. et Salv. P. Z. S. 1868,
p. 456), but has the wings more distinctly striped, and the back
olive-brown, with black markings, and not of a uniform ferruginous.

The type specimen of this little Crake was obtained during the voyage of
the 'Beagle,' on board the ship, when in the Rio Plata. Another specimen
was captured off the coast of Uruguay and brought alive to England in
1876. An example of the same species in the Paris Museum was procured by
d'Orbigny in Patagonia.

In the southern part of the Argentine country the Little Waterhen is a
summer visitant, and very abundant in the marshes along the Plata. In
language and habits it is like the Coots: it is not often seen on land,
and feeds principally as it swims about in a jerky manner among the
floating weeds. It appears in October, migrating exclusively, I think,
by night; and after the autumnal departure an individual is rarely seen.
By day they are shy and retiring, but scatter abroad in the evening,
frequently uttering their hollow mysterious cry, called _the witch
laugh_ by superstitious people, and resembling a sudden burst of
hysterical laughter, the notes beginning loud and long, becoming brief
and hurried as they die away.

western provinces of the Argentine Republic. Mr. Barrows tells us it is
abundant on the Lower Uruguay, and Dr. Burmeister met with it on the

This is the largest of the three Coots found within our limits, and
further distinguishable by the great size of the feet and the bright
red markings at the base of the yellow bill. It seems to be generally
distributed over the lagoons of the Pampas. Dr. Burmeister obtained
specimens at Mendoza and Paraná, Durnford near Buenos Ayres and in
Chupat, and Mr. Barrows in Entrerios, where he says it is not uncommon
in the cold weather. In general plumage this Coot closely resembles the
Yellow-billed Coot, but differs in the base of the upper mandible being
of a deep orange-red, this colour extending to the middle of the frontal
shield, and in the absence of white on the secondaries. The naked
part of the leg above the foot is also of a bright red, hence Azara's
appropriate name of "Red-gartered Coot."

Durnford received the eggs of this Coot from a correspondent living to
the south of Buenos Ayres, where it was said to be "quite common." He
describes the eggs as being readily distinguishable from those of the
two other species by their larger size.

_Hab._ Uruguay, Argentina, Chili, and Patagonia.

The want of the white margin to the outer primary and the smaller and
pointed head-shield distinguish this Coot from the preceding species.
From _F. leucoptera_ it may be at once known by the absence of the white
tips to the secondaries.

Durnford found the Red-fronted Coot common, and breeding in the lagoons
north of Buenos Ayres. The nests of this bird and of _F. leucoptera_, he
tells us, are much alike, but those of the present species are perhaps
rather the smaller. "They are formed of reeds, and placed in clumps of
the same, the bottom just above the water. The eggs vary in number from
six to eight, and also differ a good deal in colour. Their ground-colour
is dark greyish brown, finely mottled and streaked with rufous and
darker brown, some of the spots being of a considerable size."

    _Description._--Dark slaty; head and neck black; crissum white, with
    a black median patch; bend of wing and outer margin of external
    primary, also the tips of some of the secondaries, white; bill

    15·0 inches, wing 7·8, tail 2·0. _Female_ similar.

_Hab._ Paraguay, Uruguay, Argentina, and Bolivia.

This is perhaps the most abundant species of _Fulica_ in the Plata
region, and certainly congregates in the largest numbers. The colour of
the beak and shield is of a very delicate yellow; the legs and feet dull
green; the head, neck, and part of the back velvet-black; all the rest
of the plumage dark slate-colour, except the under coverts of the tail,
which are white, and render the bird very conspicuous when it is
swimming away with the tail raised vertically.

On the pampas, in large marshy lagoons, this Coot is sometimes seen in
immense numbers; thousands of birds uniting in one flock, and spreading
over the low shores to feed, they look like a great concourse of Rooks.
But they are exceedingly timid, and at the sight of a bird of prey or
other enemy they all scuttle back to the water, tumbling over each other
in their haste to reach it. They rise in a peculiar manner, rapidly
striking the surface of the water with their great lobed feet, often for
a distance of twenty or thirty yards before they are fully launched in
the air. They are loquacious birds, and when swimming about concealed
among the thick rushes are heard answering each other in a variety of
curious tones, some of their loud, hollow-sounding, reiterated cries
resembling peals of laughter.

The nest is a slovenly structure of rushes lying on the water, with a
very slight depression for the eggs, which are ten or twelve in number.
These are long, pointed at one end, dull cream-colour, marked over the
whole surface with small blackish and purple spots.


The Courlans are a peculiar American family, intermediate between the
Cranes and the Rails. Of the two known species, which are nearly allied,
one occurs in the Argentine Republic.

    _Description._--Above brown; forehead, lores, and chin greyish
    white; neck striped with white: beneath similar; bill brown; legs
    greenish grey: whole length 24·0 inches, wing 13·0, tail 5·0.
    _Female_ similar.

_Hab._ South America.

This curious bird has a blackish-brown plumage, glossed with bronze on
the upper parts; its total length is about two feet and a half, and the
wings, when spread, measure nearly four feet from tip to tip. It has
been called "an abnormal relative of the Rails at most," and in its
peculiar flight and many of its habits certainly differs very widely
from the Rails.

The beak of this bird is nearly 5 inches long, straight, and of an iron
hardness; the tip is slightly bent to one side, the lower mandible
somewhat more than the upper. The tongue extends to the extremity of the
beak; at the end it is of a horny toughness, and frayed or split into
filaments. This beak is a most effective instrument in opening shells;
for where mollusks abound the Courlan subsists exclusively on them, so
that the margins of the streams which this bird frequents are strewn
with innumerable shells lying open and emptied of their contents.

Every shell has an angular piece, half an inch long, broken from the
edge of one valve. Mussels and clams close their shells so tightly that
it would perhaps be impossible for a bird to insert his beak, however
knife-like in shape and hardness, between the valves in order to force
them open; therefore I believe the Courlan first feels the shell with
his foot whilst wading, then with quick dexterity strikes his beak into
it before it closes, and so conveys it to the shore. Otherwise it would
be most difficult for the bird to lift the closed shell from the water
and to carry it to land; but supposing it could do this, and afterwards
succeed in drilling a hole through it with its beak, the hole thus made
would have jagged edges and be irregular in shape. But the hole is, as I
have said, angular and with a clean edge, showing that the bird had just
thrust his beak half an inch or an inch between the valves, then forced
them open, breaking the piece out during the process, and probably
keeping the shell steady by pressing on it with its feet.

By day the Courlan is a dull bird, concealing itself in dense reed-beds
in streams and marshes. When driven up he rises laboriously, the legs
dangling down, and mounts vertically to a considerable height. He
flies high, the wings curved upward and violently flapped at irregular
intervals; descending, he drops suddenly to the earth, the wings
motionless, pointing up, and the body swaying from side to side, so
that the bird presents the appearance of a falling parachute. On smooth
ground he walks faster than a man, striking out his feet in a stately
manner and jerking the tail, and runs rapidly ten or twelve yards before
rising. At the approach of night he becomes active, uttering long clear
piercing cries many times repeated, and heard distinctly two miles away.
These cries are most melancholy, and, together with its mourning plumage
and recluse habits, have won for the Courlan several pretty vernacular
names. He is called the "Lamenting Bird" and the "Crazy Widow," but is
more familiarly known as the "Carau."

Near sunset the Caraus leave the reed-beds and begin to ascend the
streams to visit their favourite fishing-grounds. They are very active
at night, retiring again at the approach of morning, and sometimes pass
the day perched on trees, but more frequently concealed in dense

As the breeding-season draws near they become exceedingly clamorous,
making the marshes resound day and night with their long wailing cries.
The nest is built among the rushes, and contains ten or twelve eggs as
large as Turkey's, slightly elliptical, sparsely marked with blotches
of pale brown and purple on a dull white ground, the whole egg having a
powdered or floury appearance. When the nest is approached the parent
birds utter sharp angry notes as they walk about at a distance. The
young and old birds live in one flock until the following spring.

The Carau is more nocturnal than the true Rails, and, having a far more
powerful flight, takes to wing more readily; in its gestures and motions
on the ground it resembles them, but differs strikingly from all Ralline
birds in the habit it possesses of flying when disturbed to some open
place, where it walks about conspicuously, watching the intruder.


The Cariamas are another purely Neotropical family of which but two
species are known. These peculiar birds, remarkable for their long legs
and harsh voices, have been regarded by some authors as allied to the
Cranes, and by others as akin to the Secretary-Vulture (_Serpentarius_),
to which they have certainly considerable superficial resemblance. Dr.
Burmeister, who has carefully investigated the osteology and anatomy of
_Cariama cristata_, has come to the conclusion that the true place of
this somewhat isolated form is near the Storks. But Huxley (P. Z. S.
1867, p. 457) has placed it along with the Cranes, though somewhat
doubtful whether it should not rather form an Order apart; and we prefer
to follow his decision.

The Crested Cariama is a native of the Campos of the interior of Brazil,
where it is well known as the "_Seriema_." Hence it extends into the
open districts of Paraguay, and, it is said, into the adjoining parts of
the Argentine Republic, though we are not able at present to give any
exact authority for this statement.

The Cariama lives on the ground among the high grasses of the Campos,
where the traveller frequently hears its loud screaming cry as he rides
along the tracks. It feeds principally upon insects and caterpillars,
but also eats berries and fleshy fruits, and, it is said, snakes and
other reptiles. It breeds in low bushes; and lays two roundish, spotted
eggs, which in colour somewhat resemble those of the Crakes and Rails.

This bird is often brought alive to Europe, and examples may always be
seen in the Gardens of the Zoological Society of London. Here they have
paired and nested on more than one occasion, but have not succeeded in
rearing their young. The frontispiece to the first volume of this work,
which represents the Crested Cariama, is taken from one of these captive

    _Description._--A very slight frontal crest; plumage cinereous, the
    feathers crossed by very narrow bands of whitish and black; lores
    and long superciliary stripe white: beneath paler on the chest;
    lower belly and crissum fulvous white; wings brownish black, beneath
    with broad blackish bars; tail like the back, but with two broad
    black subterminal cross bands, except on the two middle rectrices;
    bill and feet black: whole length 28·0 inches, wing 12·0, tail 14·0.
    _Female_ similar.

_Hab._ Northern Argentina.

This Cariama, which much resembles the Crested Cariama in general
appearance though smaller in size, and distinguished by several
structural characters, is one of the many discoveries of the
distinguished naturalist whose name it appropriately bears. Dr.
Burmeister first met with the "Chuñia," as this bird is called by the
natives, in the province of Tucuman during his travels in the northern
parts of the Argentine Republic in 1859.

The Chuñia, he tells us, is naturally friendly to mankind, and is often
kept tame in the courtyards of houses along with the domestic fowls,
amongst which it stalks about, eating remnants of flesh and large
insects, especially grasshoppers. At night it roosts upon the roofs of
the corridors.

In a free state the Chuñia lives in the forests, running about in the
bush in the daytime, and roosting in the summit of the large trees. The
nest is placed in bushes, not very high, and the young birds are often
taken when half-fledged and become quickly accustomed to captivity.

Dr. Burmeister first met with this bird at La Invernada between Tucuman
and Catamarca[10], but tells us that it inhabits besides these two
provinces the adjoining districts of La Rioja and Santiago del Estero.
It is always easier to hear it than to see it, for its loud screaming
voice may be recognized at a distance, but when approached in the bush
it keeps a discreet silence.

  [10] See Burmeister, 'Reise durch die La Plata-Staaten,' ii. p. 195.

Several examples of Burmeister's Cariama have been received alive in
the Gardens of the Zoological Society of London, from one of which an
excellent figure has been taken by Mr. Smit (see P. Z. S. 1870, plate
xxxvi.). The frontispiece of the present volume is a reduction of that
figure by the same artist.



The Jacanas are a tropical group of birds with a somewhat general
resemblance to the Rails, but with their toes enormously elongated, so
as to enable them to move with facility over water-plants on the surface
of lakes and ponds. In essential structure, however, they are now
ascertained to be most nearly allied to the Plovers.

One genus of Jacanas (_Parra_) is peculiar to America, and a single
species of this genus occurs in the Argentine Republic.

385. PARRA JACANA (Linn.).

    _Description._--Head and neck purplish black; back and wings bright

    brown; flanks dark chestnut; breast dark black; abdomen purplish;
    tail chestnut tipped with black; wattles on head and base of bill
    red, rest of bill yellow; feet olive: whole length 10·5 inches, wing
    5·8, tail 2·2. _Female_ similar.

_Hab._ South America from Venezuela down to Buenos Ayres.

The beautiful Jacana or Jassana, sometimes called _Alas-amarillas_ in
the vernacular, differs very widely from all the other members of the
Limicoline Order in its appearance, which is most singular--the toes
being enormously long, the head ornamented with red lobes, and the
wings armed with spurs, these and the beak being of a bright yellow.
The colouring of the plumage heightens the novelty of its appearance;
the head, neck, and underparts being black; the shoulders, back, and
wing-coverts chestnut; while the quills, which have a bright satiny
lustre, are apple-green in colour, and in some lights appear golden

In the southern part of the Plata district the Jacana is migratory,
arriving from the north in Buenos Ayres early in October, either singly
or in small parties. In their migration they appear to follow the course
of the Plata; and, though some individuals are found breeding inland,
they are for the most part confined to the littoral marshes.

The Jacanas journey by very easy stages, frequently alighting to rest by
the way; for they are so incapable of sustained flight that boys on the
pampas occasionally take them, pursuing them on horseback till the birds
drop down exhausted. I believe the migratory Rails travel in the same
way--a matter not easily determined, as they migrate by night; but they
are feeble-winged creatures, and when driven to rise flutter away as if
wounded. I have observed the Jacanas migrating by day, but would not
for this reason affirm that they do not journey by night, since the
Bartram's Sandpiper and other species journey both day and night.

The Jacana flies swiftly, in a straight line and close to the surface:
the wings flutter rapidly; and there are frequent intervals of gliding.
When rising it presents a most novel appearance, as the lovely pale
green of the wings is quite concealed when the bird is at rest; the
beauty of its flight is thus greatly enhanced by the sudden display of
a hue so rare and delicate. At a distance from the beholder, and in a
strong sunshine, the wings appear of a shining golden yellow. Not only
when flying does the Jacana make a display of its beautiful wings;
without rising it has a way of exhibiting them, appearing to delight as
much in them as the Cockatoo does in its crest or the Peacock in its
train. When several of these birds live in company, occasionally they
all in one moment leave their feeding, and with quick excited notes, and
clustering together in a close group, go through a singular and pretty
performance, all together holding their wings outstretched and agitated,
some with a rapid fluttering, others with a slow-moving leisurely motion
like that of a butterfly sunning itself. The performance over, the birds
peaceably scatter again. I have never observed Jacanas fighting.

Shortly after arriving they pair, and build a simple nest with few
materials, usually on the floating weeds. The eggs are four, in shape
like Snipe's eggs, and have deep-brown spots on a pale yellowish-brown
ground. During incubation the male keeps guard at some distance from
the nest, and utters a warning cry at the approach of an intruder; the
female instantly flies from the nest, but in rising renders herself very
conspicuous. When the nest is approached the parent birds hover about,
occasionally fluttering as if wounded, all the time keeping up a clamour
of hurried angry notes somewhat resembling the barking cries of the
Black-collared Stilt.


Plovers are found all over the world's surface and in every degree
of latitude, and some of the species have an almost cosmopolitan
distribution. In the Neotropical Region about twenty Plovers are known,
of which seven are found within our limits. Three of these are Antarctic
species that visit Argentina during the winter, one arrives in the
opposite season from the north, and the other three are more or less
abundant residents.

[Illustration: CAYENNE LAPWING. (Seebohm's 'Plovers,' p. 216.)]

_Hab._ Eastern South America.

The Lapwing of La Plata is considerably larger than the well-known
Lapwing of the Old World, but closely resembles that bird in the general
colour of the plumage, in the long, slender, black crest, and in general
appearance. Throughout the Argentine country it is called _Téru-téru_,
from its ever-repeated dissyllabic cry; west of the Andes the vernacular
name is _Queltregue_, also in imitation of its notes. It has red legs,
crimson irides, a rosy beak tipped with black, and coral-red wing-spurs;
and these spots of bright colour add to its bold striking appearance.
In size, beauty, and spirit it is a king among the Plovers, while its
jealous aggressive disposition gives it the character of a tyrant
amongst birds in general. On the pastoral pampas (the district from
which the giant grasses have disappeared) it is excessively abundant;
and it is there resident, although, as with most strong-winged resident
species, some individuals do certainly migrate, small parties being
occasionally seen in spring and autumn flying steadily at a great
height, apparently performing a long journey. As a rule the birds pair
for life, and remain always on the spot where they breed. They may be
persecuted with guns, their eggs taken year after year, even the ground
turned up with the plough, but they still refuse to be driven out.
In regions having a broken surface--hills, woods, and sheltered
hollows--birds naturally get attached to one spot, for each locality
possesses its own features, and individuals frequenting it acquire
a knowledge of its advantages. The vast pampas have a uniform level
surface, and produce the same kinds of food in the same quantities. They
are parched with droughts and flooded by rains alternately, and swept
by dust-storms in summer and cold gales in winter--violent enough, one
would imagine, to drive every winged creature away and obliterate all
marks of home. Again, the powerful flight of this species would enable
it to take long journeys, and, if unaffected by atmospheric changes,
scarcity of food and water might be a temptation to seek new regions.
But through all vicissitudes the Téru-téru clings to its chosen spot of

In defence of its territory it wages perpetual war against most living
creatures, the objects of its special abhorrence being men, dogs, rheas,
and birds of prey generally. Its noisy cry and irascible temper are
spoken of by most travellers and naturalists; for no person riding
across the pampas could possibly overlook the bird, with its screaming
protests against all trespassers perpetually ringing in his ears; but
they have all omitted to mention the singular habit which this bird has
of associating in sets of three for the purpose of amusement or
play. Each couple, as I have said, live always together on their own
pretty-well-defined plot of ground, which they jealously guard from
intrusion. Yet if one watches a pair of them for a while he presently
sees another--one of a neighbouring couple--rise up and fly to them,
leaving his own mate to take care of home; and, instead of resenting
this visit as an intrusion, they welcome it with notes and signs of
manifest pleasure. Advancing to the visitor, they place themselves
behind it, and then all three, keeping step, begin a rapid march,
uttering loud drumming and rhythmical notes in time with their
movements, the notes of the birds behind coming in a rapid stream,
while the leading bird utters loud single notes at regular intervals.
The march ceases, the leader stretches out his wings, still emitting
loud notes, while the other two, with puffed-out plumage, standing
exactly abreast, stoop forward until the tips of their beaks touch the
ground, and, sinking their voices to a murmur, remain for some time
in this singular posture. The performance is then over; the birds all
resume their natural attitudes, and the visitor takes his leave. It
is quite certain that this display has no connection with the sexual
feeling, for it is indulged in all the year round, at all hours of the
day, and also during moonlight nights. It is simply the bird's manner
of expressing its joyous spirits; for most living creatures--birds
especially--have more or less well-defined methods of playing; and
playday with the Téru is every day, and at very brief intervals. And yet
the grave pompous air of the birds, and the military precision of their
movements, might easily lead an observer to attribute these displays
to some more important motive. Play is not only indulged in with
neighbours; there are many solitary Térus continually wandering about
from place to place--probably young birds not yet settled in life--and
when one of these vagrants passes near a pair he is immediately invited
to join them, and, when he alights, all go through the performance
together with great zest. In this case, however, as soon as it is over,
the strange bird is attacked with great spirit and chased away; and if
by chance he comes down again near them, they hasten to drive him up
with increased fury.

While watching their antics, which the Gauchos call the Téru's
quadrilles, a curious subject of inquiry suggested itself to my mind. It
appeared to me that its manner of playing has had a reflex effect strong
enough to mark the bird's whole character--language, bearing, and habits
being coloured by it, and even the domestic relations interfered with.
And with regard to the latter point, though it is the rule that each
cock bird has only one hen, I have known several instances of a cock
with two hens, the two females laying their eggs in one nest and taking
turns in sitting on them. I have also found instances of two males to
one female; and in one case, where I watched the birds, I noticed that
when the female was on the nest the males stood over her, one on each

I once had my attention drawn to a large concourse of Térus by the
strange behaviour of two individuals amongst them, and I stayed to watch
their proceedings. It was in the dry hot weather, and a great many
birds had congregated to drink at a lagoon. Some hundreds of them were
standing about, quietly preening their feathers, and in the middle of
the flock two birds were conspicuously marching about, stiff and upright
as a couple of soldiers engaged in some military exercise, and uttering
loud notes full of authority. Every few minutes a fresh bird would
arrive and alight at some distance from the water, on which the two
noisy birds would bustle up, and, ranging themselves behind it, run it
with loud drumming notes to the margin; then, standing close together,
they would wait till its thirst was quenched, after which they would run
it away to some distance from the water, of which they seemed to have
made themselves dispensers. For over an hour I continued watching them,
and every bird that arrived was conducted to and from the water in this
ceremonious manner.

Occasionally several couples unite and soar about in a compact flock;
they divide into sets of three birds each, then hover for some time, all
waving their wings exactly in time and screaming their notes in unison,
and these movements seem like an imitation in the air of the usual
marching and drumming performance on the ground.

The breeding-season of the Térus begins as early as the month of June
in favourable seasons; severe cold, drought, or other causes sometimes
delays it to August. The nest is a shallow circular hollow made by the
bird on the level plain, and lined with broken grass-stems and small
fragments of thistle-stalks; the eggs are four, rather sharply pointed
at one end, and have an olive-green ground-colour spotted with black.
The eggs in different nests vary greatly in size, ground-colour, and in
the amount of black they are marked with, no two birds laying eggs
exactly alike.

While the female is on the nest the male keeps watch at a distance of
twenty or thirty yards, and utters a low warning cry in case of danger.
The female leaves the nest sometimes by running, but oftener flies from
it, and by marking the spot she rises from, it is easy to find the nest
on the open level pampas. In the course of a morning's ride I have
picked up as many as sixty-four eggs. During incubation the birds are
excessively watchful and jealous, their irritability increasing with the
growth of the chick in the shell; and at that time they will attack
any bird of prey approaching the nest with amazing virulence. When
approached by a human being they fly to meet him when he is still far
from them, and hovering, with loud screams, over him, dash down at
intervals, threatening to strike with their wing-spurs, coming very
close to his head. Unable to intimidate the enemy with this show of
violence, the bird changes its tactics, and, alighting at some distance,
counterfeits the action of a bird seeking its nest. With well-acted
caution and secrecy in its manner, it runs silently along, stooping low,
and having found a slight nest-like depression on the surface, sits on
it, half opens its wings, and begins gathering all the small sticks or
straws within its reach and carefully arranges them about it, as most
ground-breeding birds do when incubating. Sometimes also, like many
other species, it tries to lead one away from the nest by feigning
lameness; but the former instinct of seeking and sitting on an imaginary
nest, which I have not observed in any other bird, seems far more
complex and admirable.

When sheep in a flock pass over the nest, the bird stands on it to
defend its eggs; and then its loud cries and outspread wings often serve
to bring the sheep, from motives of curiosity, about it. Even with a
dozen sheep clustered round it the bird stands undaunted, beating
their faces with its wings; but, unhappily for it, if the shepherd is
following, the loud cries of the bird bring him to the spot, and the
eggs so bravely defended are taken.

_Hab._ America.

This closely allied representative of the Golden Plover of Europe,
from which it is distinguishable mainly by its rather larger size and
smoky-grey axillaries, visits South America in autumn.

The American Golden Plover is abundant and well known to everyone by its
native name _Chorlo_ throughout Southern Argentina. Its wild clear notes
are first heard about the last week in August; and among the first
comers many individuals are seen still wearing the nuptial dress. After
their long journey from the Arctic regions they are lean and not worth
shooting; two months later they become excessively fat, and are then
much appreciated by _gourmets_. But although so regular in their arrival
they do not regularly visit the same localities every season; the bird
may be abundant in a place one year and scarce or absent altogether the
next. During the spring, from September to December, they prefer open
plains with short grass and in the neighbourhood of wet or marshy
ground; at the end of December, when the giant thistle (_Carduus
mariana_), which often covers large areas of country, has been burnt up
by the sun and blown to the ground, they scatter about a great deal in
flocks of from one to four or five hundred. At noon, however, they all
resort to a lagoon or marshy place containing water, congregating day
after day in such numbers that they blacken the ground over an area of
several acres in extent; and at a distance of a quarter of a mile
the din of their united voices resembles the roar of a cataract. As
population increases on the pampas these stupendous gatherings are
becoming more and more rare. Twenty-five years ago it was an exceptional
thing for a man to possess a gun, or to use one when he had it; and if
Chorlos were wanted, a Gaucho boy, with a string a yard long with a ball
of lead attached to each end, could knock down as many as he liked. I
have killed them in this way myself, also with the _bola perdida_--a
ball at the end of a long string thrown at random into a cloud of birds.

The habits, flight, and language of the Golden Plover need not be spoken
of here, as this bird has been so often and exhaustively described by
North-American ornithologists. The only peculiarity it possesses which I
have not seen mentioned, is its faculty of producing a loud sound, as of
a horn, when a few passing birds, catching sight of others of their kind
on the ground below, descend violently and almost vertically to the
earth with unmoving wings. This feat is, however, rarely witnessed; and
on the first occasion when I heard the sound high above me, and looked
up to see half a dozen Chorlos rushing down from the sky, the sight
almost took my breath away with astonishment.

The Golden Plover appears to be most abundant on the pampas between
the thirty-fourth and thirty-sixth parallels of latitude, but how
far south its range extends has not yet been ascertained. The return
migration begins early in March, and yet Mr. Barrows met with it in
the neighbourhood of Bahia Blanca and on the Sierra de la Ventana from
February 8 to March 19. During most of this time he says it was abundant
in flocks of from twenty to two hundred birds, which appeared to be
moving uniformly _south_ or _south-west_.

_Hab._ Antarctic America.

This species in its gait, flight, and general appearance closely
resembles the American Golden Plover, but is smaller than that bird,
and its sober upper plumage is unrelieved with flecks of golden colour.
It breeds in South Patagonia and the Falklands, and migrates north in
autumn, appearing on the pampas in April, and being met with there
throughout the winter; hence the vernacular name _Chorlito de invierno_
(Little Winter Plover). In its winter dress the upper plumage is greyish
drab colour; the breast dark brown; the belly white. It is shy and
active in disposition, has a very rapid flight, and is seen in flocks
varying greatly in number, from a dozen to two or three hundred
individuals. When feeding the birds scatter very widely, running swiftly
over the ground in all directions. When on the wing it frequently utters
its cry, which has not the mellow tone of the Golden Plover's note, but
it is wonderfully clear and far-reaching, and impresses the listener
with its wildness and melancholy.

Their return migration takes place in August.

_Hab._ Patagonia, Falkland Islands, Chili, and Argentina.

The pretty little Belted Plover inhabits the Falklands and South
Patagonia, and migrates north in winter as far as Paraguay; but it is
not anywhere common, and is seldom seen in parties exceeding half a
dozen in number. It is extremely active, always preferring wet grounds
to dry, and runs rapidly over the mud in search of food like a Tringa.
Its only language is a low clicking note uttered when taking wing.

Some individuals remain to breed as far north as the pampas of Buenos
Ayres. Mr. Gibson says the nest is always placed near the water, and is
a slight scrape in the ground lined with dry grass. The eggs are three
in number, have black spots on an olive ground; and in shape resemble
Lapwing's eggs.

Durnford also found it breeding in the Chupat Valley in September 1877.

Azara's Sand-Plover is distributed all over South America east of the
Andes, and has been obtained by Mr. Salvin in Guatemala. It is a close
ally of the Kentish Plover of Europe (_Æ. cantiana_), but has the black
pectoral band complete in the adult form.

This Plover appears to be an inland species. Durnford observed it in
October, December, and February in the neighbourhood of Buenos Ayres, on
"dry sandy ground," frequenting the same sort of places as the Common
Ring-Plover in England. He also met with it during his last journey to
Tucuman, and Mr. Barrows found it "rather abundant" in small flocks all
over the open country in Entrerios.

[Illustration: SLENDER-BILLED PLOVER. (Seebohm's 'Plovers,' p. 111.)]

_Hab._ Southern half of South America.

This pretty and curious Plover, with a Snipe-like beak, inhabits South
Patagonia and the Falklands. In the autumn it migrates north, and during
the cold season is found sparsely distributed throughout the Argentine
States, and passes into Bolivia and Peru. On the pampas it is most
abundant in April, but most of the birds seen during that month are
travellers to warmer latitudes.

It is a shy and exceedingly active bird, somewhat larger than the Golden
Plover in size, and in the Plata district is usually called _Chorlo
canela_, from the prevailing cinnamon-red tint of the plumage. It is
distinguished in the family it belongs to by the great length of its
straight slender probe-like bill, unlike that of any other Plover; and
it also has other structural peculiarities, the toes being exceptionally
short and thick, the frontal bone curiously modified, and the eyes
enormously large, like those of a nocturnal species. I do not think,
however, that it migrates by night, as I have never heard its peculiar
passage-cry after dark. A flock is usually composed of from a dozen to
thirty individuals, and when on the ground they scatter widely, running
more rapidly than any other Plover I am acquainted with. When they
travel the flight is swift and high, the birds much scattered. They
possess no mellow or ringing tones like other members of the Plover
family; on the ground they are silent, but when taking wing invariably
utter a long tremulous reedy note, with a falling inflection, and
usually repeated three or four times. The sound may be imitated by
striking on the slackened strings of a guitar. This cry is frequently
uttered while the birds are migrating.

On the Rio Negro in Patagonia I observed this Plover only in the winter
season; but Durnford found it nesting in the valley of the Sengel in
Chupat in the month of December.

This Oyster-catcher is widely distributed along the coasts of North and
South America, from Nova Scotia to Patagonia. Durnford found it nesting
near Tombo Point in Central Patagonia in the month of December, but
failed to obtain the eggs.

At the same place Durnford also observed the Black Oyster-catcher (_H.
ater_), but that is an Antarctic species, which may probably not come
further north.


The family Thinocoridæ, which embraces the two genera _Thinocorus_ and
_Attagis_, is a peculiar group of South-American birds of somewhat
Partridge-like appearance, and associated by the older authors with the
Gallinæ, but now known to be most nearly allied in essential structure
to the Plovers. The Seed-Snipes are inhabitants of bare and desolate
districts, being found in the northern parts of the continent only on
the high Andes, but descending to the sea-level in Patagonia and the
Falkland Islands. The species are few in number, only about six being
known, of which two occur within Argentine limits.

_Hab._ Western Peru, Bolivia, Chili, Patagonia, and Argentina.

This curious bird has the grey upper plumage and narrow, long,
sharply-pointed wings of a Snipe, with the plump body and short strong
curved beak of a Partridge. But the gallinaceous beak is not in this
species correlated, as in the Partridges, with stout rasorial feet; on
the contrary, the legs and feet are extremely small and feeble, and
scarcely able to sustain the weight of the body. When alighting the
Seed-Snipe drops its body directly upon the ground and sits close like
a Goatsucker; when rising it rushes suddenly away with the wild hurried
flight and sharp scraping alarm-cry of a Snipe. It is exclusively a
vegetable-feeder. I have opened the gizzards of many scores to satisfy
myself that they never eat insects, and have found nothing in them but
seed (usually clover-seed) and tender buds and leaves mixed with minute
particles of gravel.

These birds inhabit Patagonia, migrating north to the pampas in winter,
where they arrive in April. They usually go in flocks of about forty or
fifty individuals, and fly rapidly, keeping very close together. On the
ground, however, they are always much scattered, and are so reluctant
to rise that they will allow a person to walk or ride through the flock
without taking wing, each bird creeping into a little hollow in the
surface or behind a tuft of grass to escape observation. During
its winter sojourn on the pampas the flock always selects as a
feeding-ground a patch of whitish argillaceous earth, with a scanty
withered vegetation; and here when the birds crouch motionless on the
ground, to which their grey plumage so closely assimilates in colour,
it is most difficult to detect them. If a person stands still close to
or in the midst of the flock the birds will presently betray their
presence by answering each other with a variety of strange notes,
resembling the cooing of Pigeons, loud taps on a hollow ground, and
other mysterious sounds, which seem to come from beneath the earth.

In the valley of Rio Negro I met with a few of these birds in summer,
but could not find their nests.

Durnford, however, who found them breeding in Chupat at the end of
October, tells us that the nest is a slight depression in the ground,
sometimes lined with a few blades of grass. "The eggs have a pale stone
ground-colour, very thickly but finely speckled with light and dark
chocolate markings; they have a polished appearance, and measure
1·3 × ·8 inch" (Ibis, 1878, p. 403).

_Hab._ Western Peru, Bolivia, Chili, and Western Argentina.

Dr. Burmeister met with examples of this Seed-Snipe, which is easily
distinguishable from the preceding species by its larger size, in the
high valleys of the Sierra of Uspallata, at an elevation of about 6000
feet above the sea-level. It is called "Guancho" by the natives after
its peculiar call-note, which, however, sounded more like "Tulco" to Dr.
Burmeister, and is often heard at night-time.

This Seed-Snipe is also found in Peru at high elevations in the Puna
region (12,000 to 14,000 feet), where M. Jelski obtained its eggs. A
description of them with some interesting notes on the habits of the
species are given in Taczanowski's 'Ornithologie du Pérou.'


Like the Plovers, the Snipes are nearly universally distributed over the
world's surface, though most abundant in northern regions. Of about 35
Neotropical species 15 are known to occur in the Argentine Republic, and
many additions to the list of these wandering birds may be reasonably

Of the fifteen Scolopacidæ already recognized as occurring within our
limits, all but three are Arctic species, which only visit the far south
during their migrations. The three exceptions are the Brazilian Stilt
(_Himantopus brasiliensis_), the Paraguay Snipe (_Gallinago
paraguaiæ_), and the Painted Snipe (_Rhynchæa semicollaris_), which are
resident all the year in the Argentine Republic.

[Illustration: Head of BRAZILIAN STILT. (P. Z. S. 1873, p. 454.)]

_Hab._ South America.

This bird is resident and common in the Plata district, and is called in
the vernacular _Téru-real_, also _Zancudo_ (stilt). It frequents marshes
and lagoons, and wades in search of food in the shallow water near the
margin. It is lively in its movements, and notwithstanding the great
length of its legs has a pretty, graceful appearance on the ground. On
the wing, however, it is seen at its best, the flight being remarkably
swift and free, while the sharply-pointed glossy-black wings contrast
finely with the snow-white plumage of the body, and the red legs
stretched out straight behind have the appearance of a long slender
tail. Stilts are fond of aerial exercises, pursuing each other with
marvellous velocity through the air, so that a few moments after the
spectator has almost lost sight of them in the sky above they are down
again within a few yards of the surface. While pursuing each other they
constantly utter their excited barking cries, which in tone remind one
of the melodious barking of some hounds.

The nest is made on the low ground close to the water, and consists
merely of a slight lining of dry grass and leaves gathered in a small
depression on the surface; the eggs are four in number, pyriform, dark
olive colour, spotted with brownish black, the spots being very thickly
crowded at the large end. During incubation the male keeps guard and
utters a warning note on the appearance of an enemy, whereupon the
female quits the nest. They also counterfeit lameness to draw a person
from the neighbourhood of the eggs or young; but in a manner peculiar to
this species; for owing to the great length of their legs they cannot
drag themselves along the ground, as ducks, plovers, partridges, and
other birds do. Placing themselves at a distance of forty or fifty yards
from the intruder, but with breast towards him, they flutter about a
foot above the ground, their long legs dangling under them, and appear
as if struggling to rise and repeatedly falling back. If approached they
slowly retire, still fluttering just above the grass and without making
any sound. After the young birds are able to fly they remain with the
parents until the following spring; and sometimes two or three families
associate together, raising the number of the flock to fifteen or twenty
birds. The young have a sharp querulous cry of two notes; the plumage is
brown and pale grey; the eyes black. After nine or ten months the adult
plumage is acquired, not by moulting, but by a gradual change in the
colours of the feathers. By the same gradual process the eye changes
from black to crimson, the outer edge of the iris first assuming a dull
reddish colour, which brightens and widens until the whole iris becomes
of a vivid red.

Wilson's Phalarope is a North-American species; which breeds in the
north-west of that continent, and descends as far south as Chili and
Patagonia during migration.

Durnford in 1876 met with this species in the Chupat Valley, "in the
still pools formed by the eddies in the river and in the adjacent
stagnant ditches." It was "usually seen in pairs." Leybold's collector
obtained specimens of it near Mendoza.

    _Description._--Above brown, striped and barred with black and
    pale fulvous; wings dark cinereous edged with white; tail of 16
    rectrices, of which the outer pair are pin-shaped: beneath white,
    breast marbled with blackish and brown: whole length 10·5 inches,
    wing 5·1, tail 2·4, bill 2·8.

_Hab._ Patagonia, La Plata, and Paraguay.

This familiar bird, called _Agachona_ in the vernacular, from its habit
of crouching close to the ground to escape observation when approached,
is abundant in the Plata district and resident, although its sudden and
total disappearance from all the open wet places where it is common in
the winter gives one the impression that it is migratory. The bird,
however, only retires to breed in the extensive lonely marshes. The nest
is a slight depression on the moist ground close to the water, and lined
with a little withered grass. The eggs are four, pear-shaped, and
spotted with black on an olive-coloured ground.

After the summer heats are over Snipes suddenly appear again all over
the country, and at this season they are frequently met with on the high
and dry grounds among the withered grass and thistles. In favourable wet
seasons they sometimes collect in large flocks, numbering not less than
five or six hundred birds, and a flock of this kind will occasionally
remain in one spot for several months without breaking up. They usually
frequent an open spot of level ground where the water just covers the
roots of the short grass; here the birds keep close together while
feeding and are visible from a long distance; but they become extremely
wary, all raising their heads in a very un-Snipe-like manner at the
slightest alarm, and taking flight with the readiness of Wild Ducks.
These flocks are, however, not often met with. Usually the Snipe is a
solitary bird, crouches close when approached, and springs up suddenly
when almost trodden on, loudly uttering its sharp scraping alarm-cry;
after rising to a considerable height, flying in a wild erratic manner,
it returns suddenly to the earth, often dropping into the grass within
twenty yards of the spot it rose from.

It is, indeed, curious to see how these habits, characteristic of the
Snipes all over the world, are so completely laid aside when the birds
associate in large flocks.

Early and late in the day many individuals are usually on the wing
engaged in their aerial pastimes, the singular grinding sounds caused
by their feathers in their violent descent from a great height being
distinctly audible at a distance of nearly a mile. It is heard
throughout the winter at all hours of the day in mild damp weather, and
on moonlight nights often until after midnight.

    _Description._--Above dark brown; head black, with a central and
    two lateral longitudinal bands of buffy white; wings ashy blackish,
    spotted with buffy white and barred with black; coverts with large
    oval spots of clear white: beneath, throat and breast dark brownish,
    with a conspicuous white neck-collar on each side; belly white,
    flanks tinged with buffy; bill greenish, reddish at tip; feet
    flesh-colour: whole length 8·0 inches, wing 4·1, tail 2·0. _Female_
    similar, but slightly larger and more brightly coloured.

_Hab._ Southern parts of South America, from Peru to Patagonia.

In the Argentine provinces this bird is called _Dormilon_ (Sleepy-head),
in allusion to its dull habits, which are like those of a nocturnal
species. It passes the daylight hours concealed in dense reed-beds,
rising only when almost trodden on; the flight is feeble and erratic,
the rapid wing-flutterings alternating with intervals of gliding, and
after going a short distance the bird drops again like a Rail into
the rushes. From its behaviour on the ground, also in flying, when it
appears dazed with the light, I have no doubt that it is altogether
nocturnal or crepuscular in its habits. It is solitary and resident, and
may be met with in small numbers in every marsh or stream in the Plata
district, where its favourite reed-beds afford it cover. It appears to
have no cry or note of any kind, for even when frightened from its nest
and when the eggs are on the point of hatching it utters no sound. The
eggs never exceed two in number and are placed on the wet ground, often
without any lining, among the close grass and herbage near the water.
They are oblong and bluntly pointed at the smaller end, and have a white
ground-colour, but so densely marked and blotched with black that in
some cases they appear to be almost wholly of that colour, or like black
eggs flecked with white.

[Illustration: Tail-feathers of PECTORAL SANDPIPER. (Seebohm's
'Plovers,' p. 443.)]

_Hab._ Arctic America, migrating south to Patagonia in winter.

The Pectoral Sandpiper is a well-known North-American species that
visits the south during migration. It breeds abundantly in Alaska,
and descends in winter through Central and South America to Chili and
Patagonia. Durnford found it abundant about the salt-lagoons of Chupat.
Near the end of August it begins to arrive in La Plata, usually in very
small flocks or singly; and among these first-comers there are some
young birds so immature and weak in appearance that one can scarcely
credit the fact that so soon after being hatched they have actually
performed the stupendous journey from the northern extremity of the
North-American continent to the Buenos-Ayrean pampas.

This species differs from other Sandpipers in being much more solitary
and sedentary in its ways, feeding for hours in one spot, and in
its Snipe-like habit of sitting close when approached and remaining
motionless watching the intruder; also in its language, its low, soft,
tremulous cry when flying being utterly unlike the sharp and clicking
sounds emitted by other species. During the hot months, when water
begins to fail, they occasionally congregate in flocks, sometimes as
many as two or three hundred individuals being seen together; but at all
times it is more usual to see them in very small flocks or singly.

breed in the high Northern Polar lands.

_Hab._ North and South America.

The Greater Yellowshank is best known as an Arctic American species,
descending south during migration, and arriving in La Plata at the end
of September or early in October, singly or in pairs, and sometimes in
small flocks. Without ever being abundant the bird is quite common, and
one can seldom approach a pool or marsh on the pampas without seeing
one or more individuals wading near the margin, and hearing their
powerful alarm-cry--a long clear note repeated three times.

These summer visitors leave us in March, and then, oddly enough, others
arrive, presumably from the south, to winter on the pampas, and remain
from April to August. Thus, notwithstanding that the Yellowshank
does not breed on the pampas, we have it with us all the year round.
Durnford's observations agree with mine, for he says that the bird is
found throughout the year near Buenos Ayres; and Mr. Barrows writes
that this species "occurs every month in the year (at Concepcion in
Entrerios), but in increased numbers during August, September, October,
and November."

This North-American species is likewise common throughout the year on
the pampas, although not nearly so common in winter (June, July, and
August) as in summer.

Durnford also found it abundant in Central Patagonia. In habits,
language, and in general appearance, except in size, it closely
resembles the Greater Yellowshank, and the two species, attracted or
deceived by this likeness, are constantly seen associating together.

Mr. Barrows, who found it near Concepcion in Entrerios, usually in
company with _Totanus melanoleucus_, did not observe it in May, June,
or July in that locality.

The well-known and well-named Solitary Sandpiper arrives later than the
other birds of its family in La Plata, and differs greatly from them in
its habits, avoiding the wet plains and muddy margins of lagoons and
marshes where they mostly congregate, and making its home at the side of
a small pool well sheltered by its banks, or by trees and herbage, and
with a clear margin on which it can run freely. As long as there is any
water in its chosen pool, though it may be only a small puddle at the
bottom of a ditch, the bird will remain by it in solitary contentment.
When approached it runs rapidly along the margin, pausing at intervals
to bob its head, in which habit it resembles the Tatlers or Yellowshanks,
and emitting sharp little clicks of alarm. Finally, taking flight, it
utters its peculiar and delightful cry, a long note thrice repeated, of
so clear and penetrating a character that it seems almost too fine and
bright a sound even for so wild and aerial a creature as a bird.

The flight is exceedingly rapid and wild, the bird rising high and
darting this way and that, uttering its piercing trisyllabic cry the
whole time and finally, dashing downwards, it suddenly drops again on to
the very spot from which it rose.

I was once pleased and much amused to discover in a small sequestered
pool in a wood, well sheltered from sight by trees and aquatic plants,
a Solitary Sandpiper living in company with a Blue Bittern. The Bittern
patiently watched for small fishes, and when not fishing dozed on a low
branch overhanging the water; while its companion ran briskly along the
margin snatching up minute insects from the water. When disturbed they
rose together, the Bittern with its harsh grating scream, the Sandpiper
daintily piping its fine bright notes--a wonderful contrast! Every time
I visited the pool afterwards I found these two hermits, one so sedate
in manner, the other so lively, living peacefully together.

Bartram's Sandpiper is another of those species which breed in North
America, and extend their winter-migrations far into the Southern
Hemisphere. It differs, however, from its fellow-migrants, which visit
the Argentine country, in its wide and even distribution over all that
portion of the pampas where the native coarse grasses which once covered
the country have disappeared, an area comprising not less than 50,000
square miles. It begins to arrive as early as September, coming singly
or in small parties of three or four; and, extraordinary as the fact
may seem when we consider the long distance the bird travels, and the
monotonous nature of the level country it uses as a "feeding area," it
is probable that every bird returns to the same spot year after year;
for in no other way could such a distribution be maintained, and the
birds appear every summer evenly sprinkled over so immense a surface.

On the pampas the bird is called _Chorlo solo_, on account of its
solitary habit, but more commonly "Batitú," an abbreviation of the
Indian name Mbatuitui. In disposition it is shy, and prefers concealment
to flight when approached, running rapidly away through the long grass
or thistles, or concealing itself behind a tussock until the danger is
past, or often, where the herbage is short, crouching on the ground like
a Snipe. It runs swiftly and pauses frequently; and while standing still
with head raised it jerks its long tail up and down in a slow measured
manner. When driven up it springs aloft with a sudden wild flight,
uttering its loud mellow-toned cry, composed of three notes, strongly
accented on the first and last; and sometimes, when the bird is much
alarmed, the first note is rapidly repeated several times like a trill.
After flying a very short distance it drops to the ground again,
agitating its wings in a tremulous manner as it comes down. In this
motion of the wings, also in many of its gestures, on the ground, its
skulking habits, and reluctance to fly it is more like a Rail than a
Snipe. It also, Rail-like, frequently alights on trees and fences, a
habit I have not remarked in any other Limicoline species.

It inhabits the pampas from September until March; but early in February
the great return-migration begins, and then for two months the mellow
cry of the Batitú is heard far up in the sky, at all hours, day and
night, as the birds wing their way north. In some seasons stragglers are
found throughout the month of April, but before the winter arrives not
one is left.

    the outer rectrices lighter, each with subterminal black crescent
    and white terminal edge: beneath buff, darker on the throat and

    the under surface of the wing, which is pure white: whole length 7·7
    inches, wing 5·3, tail 2·5. _Female_ similar.

_Hab._ Arctic America, descending south to Buenos Ayres in winter.

This species is also an annual visitor to the pampas from the Arctic
regions where it breeds. It begins to arrive, usually in small bodies,
early in the month of October; and during the summer is seldom met with
in flocks of any size on the pampas, but is usually seen on the dry
open ground associating in small numbers with the Golden Plover, the
Whimbrel, and other northern species. I, however, think it probable that
it travels further south than its fellow-migrants from North America,
and has its principal feeding-grounds somewhere in the interior of
Patagonia; also that its northern journey takes place later than that of
other species. In some seasons I have observed these birds in April
and May, in flocks of two to five hundred, travelling north, the birds
flying very low, flock succeeding flock at intervals of about fifteen
minutes, and continuing to pass for several days.

_Hab._ Arctic America, descending south to Central Patagonia in winter.

The Hudsonian Godwit, Mr. Seebohm tells us, "breeds on the tundras of
North America north of the forest-growth, from Alaska to Baffin's Bay,
but is rare at the western extremity of its range." In winter it goes
far south, like most of the other Grallæ.

Durnford found it "common from April to September about the lagoons and
arroyos to the south of Buenos Ayres;" and states that in habits it much
resembles the Bar-tailed Godwit of Europe (_Limosa lapponica_). He also
met with it in Chupat, and obtained two specimens there on the 13th of
November, 1876.

I have met with it in flocks during the summer of the Southern
Hemisphere, and these birds, as well as those obtained at Chupat in
November by Durnford, were undoubtedly visitors from the north; but
invariably small flocks of half a dozen to thirty birds begin to appear
on the pampas in April, and remain there, as Durnford says, until
September, when the northern migrants are nearly due. These individuals
must therefore breed near the extremity, or beyond the extremity, of
South America. It is very curious, to say the least of it, that the
Arctic and Antarctic regions of America should possess the same species,
and that, at opposite seasons of the year, it should winter in the same
district, so far from the breeding-place of one set of individuals, and
so near to that of the other! Captain Abbott observed the Hudsonian
Godwit in the Falkland Islands in flocks in the month of May (see Ibis,
1861, p. 156). These could not have been Alaskan birds, but were no
doubt southern breeders on their way north, for that they could winter
so far south seems incredible.

      Ridgw. Water-B. N. A._ i. p. 318.

    _Description._--Above dark brown, each feather edged or spotted with
    pale buff or dirty white, becoming most strongly marked on the rump
    and upper tail-coverts; wings uniform dusky brownish, narrowly
    edged with white; tail buffy brown, transversely barred with dusky:
    beneath, throat white; rest of under surface pale buff, with more
    or less V-shaped dusky markings on the breast, flanks, and under
    tail-coverts; axillaries and under wing-coverts pale chestnut,
    transversely barred with dusky: whole length 11·6 inches, wing 8·14,
    tail 3·3. _Female_ similar.

_Hab._ Arctic America, extending south to Patagonia in winter.

The Esquimo Whimbrel, which, as Mr. Seebohm tells us, may be
distinguished from all its congeners by having scarcely any traces of
bars on its primaries and by the back of the tarsus being covered with
hexagonal reticulations, migrates from the tundras of North America,
where it breeds, to the southern extremity of South America.

Mr. Barrows noted its first arrival at Concepcion in Entrerios on
September 9th, 1880, "in large flocks." After the middle of October none
were seen there.

The same excellent observer saw it almost daily on the pampas between
Azul and Bahia Blanca, "in company with the Golden Plover and Bartram's
Sandpiper, until late in February."

From the 8th to the 10th of October, 1877, Durnford saw large flocks
of this Whimbrel in the Chupat Valley flying south, and obtained two
specimens. Capt. Packe and Capt. Abbott both procured examples in the
Falkland Islands.



The Gulls and Terns of the Rio de la Plata require more attention, and
it is probable that several additions will have to be made to the list.
At present we can enumerate only nine species as certainly found within
our limits. The number of known Neotropical Laridæ is about thirty-three.

    orange; feet red: whole length 19·0 inches, wing 15·0, tail 5·0.
    _Female_ similar.

_Hab._ Coasts of South America.

The Black-tailed Skimmer, which is common on the coasts of Brazil,
migrates south in spring, following the course of the Plata river in its
journey, and appearing in pairs or small flocks in the neighbourhood of
Buenos Ayres during the month of October. Its chief breeding-ground is
on the extensive mud-banks and islets at Bahia Blanca on the Atlantic
coast. The return-migration occurs in March.

Darwin met with the Scissor-bill during his excursion up the Paraná in
October 1833, and speaks of it as follows (Nat. Journ. p. 161):--

"I here saw a very extraordinary bird, called the Scissor-beak
(_Rhynchops nigra_). It has short legs, web feet, extremely long-pointed
wings, and is of about the size of a Tern. The beak is flattened
laterally, that is in a plane at right angles to that of a Spoonbill or
Duck. It is as flat and elastic as an ivory paper-cutter, and the lower
mandible, differently from every other bird, is an inch and a half
longer than the upper. I will here detail all I know of the habits of
the Scissor-beak. It is found both on the east and west coasts, between
lat. 30° and 45°, and frequents either salt or fresh water. The specimen
now at the Zoological Society was shot at a lake near Maldonado, from
which the water had been nearly drained, and which, in consequence,
swarmed with small fry. I there saw several of these birds, generally in
small flocks, flying backwards and forwards, close to the surface of the
lake. They kept their bills wide open, and with the lower mandible half
buried in the water. Thus skimming the surface, they ploughed it in
their course; the water was quite smooth, and it formed a most curious
spectacle to behold a flock, each bird leaving its narrow wake on the
mirror-like surface. In their flight, they frequently twist about with
extreme rapidity, and so dexterously manage, that with their projecting
lower mandible they plough up small fish, which are secured by the upper
half of their scissor-like bill. This fact I repeatedly saw, as, like
Swallows, they continued to fly backwards and forwards, close before me.
Occasionally, when leaving the surface of the water their flight was
wild, irregular, and rapid; they then also uttered loud, harsh cries.
When these birds are fishing, the length of the primary feathers of the
wings is seen to be quite necessary, in order to keep the latter dry.
When thus employed, their forms resemble the symbol by which many
artists represent marine birds. The tail is much used in steering their
irregular course.

"These birds are common far inland along the course of the Rio Paraná;
it is said they remain during the whole year, and breed in the marshes.
During the day they rest in flocks on the grassy plains, at some
distance from the water. Being at anchor, as I have said, in one of the
deep creeks between the islands of the Paraná, as the evening drew to a
close, one of these Scissor-beaks suddenly appeared. The water was quite
still, and many little fish were rising. The bird continued for a long
time to skim the surface, flying in its wild and irregular manner up and
down the narrow canal, now dark with the growing night and the shadows
of the overhanging trees. At Monte Video I observed that some large
flocks during the day remained on the mud-banks at the head of the
harbour, in the same manner as on the grassy plains near the Paraná; and
every evening they took flight direct to seaward. From these facts, I
suspect that the _Rhynchops_ generally fishes by night, at which time
many of the lower animals come most abundantly to the surface. M. Lesson
states that he has seen these birds open the shells of the _Mactræ_,
buried in the sand-banks on the coast of Chile; from their weak bills,
with the lower mandible so much produced, their short legs and long
wings, it is very improbable that this can be a general habit."

_Hab._ Coasts and rivers of South America.

This large-billed Tern, "with a slightly forked tail, but amply
developed feet," is occasionally seen near Buenos Ayres.

Durnford tells us that he found it common at Baradero in April in small
parties, and watched one flock for some time. These individuals kept
circling over a mill-pond, which evidently held a good supply of small
fishes; for they constantly kept darting into the water. This species,
Durnford adds, has a note quite unlike that of any other Tern; it is
nearly similar to the cry of the "Tero-tero" (_Vanellus cayennensis_),
for which he had often mistaken it.

This large Tern seems to occur on the Rio Paraná, according to Azara.
It is certainly found in Southern Brazil, where Mr. Rogers obtained a
series of specimens now in the collections of Messrs. Salvin and Godman
and of Mr. H. Saunders.

_Hab._ Coasts of S.E. Brazil, Argentina, and Chili.

This beautiful Tern, peculiar for its white head in the adult dress, was
observed by Durnford on Flores Island in the Rio de la Plata, and in
other places on the coast of the Argentine Republic. One was obtained
near Punta Lara, in October 1876; and many more since by Mr. E. Gibson,
Commander MacFarlane, and others.

This is a black-headed Tern with a blood-red bill, which is found
abundantly on the coast of Patagonia, and extends up the Atlantic coast
to Rio. It was noticed by Durnford near Buenos Ayres, and found breeding
by the same excellent observer at Tombo Point, about sixty miles to the
south of Chupat, in December 1877. He tells us:--

"I was prepared when I visited this place in December to see a
considerable quantity of birds; but the number that met my eyes
fairly staggered me. Their nests covered an area about 150 yards
square. Allowing three nests and five eggs for every square yard (a
very moderate computation, it being difficult to walk without treading
on the eggs), we arrive at the extraordinary number of 67,500 nests,
135,000 birds, and 112,500 eggs; and, wonderful as these figures may
appear, I feel sure that I have rather understated than overstated the
numbers. The nests were mere hollows in the fine gravel or shingle,
and contained one, two, and sometimes three eggs. The latter generally
have the appearance of the eggs of the Sandwich Tern, though of course
smaller; and out of many hundreds I did not see two alike."

    bird the crown is grey.

This is a little Tern, belonging to the same group as the European
_Sterna minuta_, with a uniform pale yellow bill. Durnford met with
it at Baradero, and says that it frequents shallow inland lagoons and
small streams, but is also found on the Rio de la Plata. Dr. Burmeister
obtained it on the Paraná, and White at Itapua, Misiones. Saunders shot
it on the Huallaga, in Peru, 2800 miles inland.

_Hab._ Both coasts of South America, from Peru on the west and Rio on

The Dominican Gull, which belongs to the same section of the group as
the well-known Black-backed Gulls of Europe, is common throughout the
Plata district in winter, from April to August. During the summer months
it confines itself to the Atlantic coast, and breeds in large numbers
in the neighbourhood of Bahia Blanca, on the extensive sand-banks
and mud-flats there; and in other suitable localities further south.
Durnford found it nesting at Tombo Point, sixty miles south of the
Chupat river.

At the approach of cold weather the Dominican Gulls leave the sea-shore
and wander inland and northward. At this season they are exclusively
flesh-eaters, with a preference for fresh meat; and when the hide
has been stripped from a dead cow or horse they begin to appear,
vulture-like, announcing their approach with their usual long hoarse
pelagic cries, and occasionally, as they circle about in the air,
joining their voices in a laughter-like chorus of rapidly-repeated
notes. Their winter movements are very irregular; in some seasons they
are rare, and in others so abundant that they crowd out the Hooded Gulls
and Carrion-Hawks from the carcass; I have seen as many as five to six
hundred Dominicans massed round a dead cow.

[Illustration: Three outer primaries of adult SPOT-WINGED GULL.
(P. Z. S. 1878, p. 202.)]

_Hab._ Southern Brazil, Uruguay, and La Plata.

This common Black-hooded Gull is found throughout the Argentine country,
down to Chupat in Patagonia, and is exceedingly abundant on the pampas
of Buenos Ayres, where it is simply called _Gaviota_. In the month of
October they congregate in their breeding-places--extensive inland
marshes, partially overgrown with rushes. The nests are formed of weeds
and rushes, placed just above the water and near together, several
hundreds being sometimes found within an area of less than one quarter
of an acre. The eggs are four in number, large for the bird, obtusely
pointed, of a pale clay-colour, thickly spotted at the big end and
sparsely on the other parts with black.

Every morning, at break of day, the Gulls rise up from their nests and
hover in a cloud over the marsh, producing so great a noise with their
mingled cries that it can be heard distinctly at a distance of two
miles. The eggs are considered a great delicacy, resembling those of
the Plover in taste and appearance, and are consequently much sought
after, so that when the locality near which a gullery is situated
becomes inhabited the birds have no chance of rearing their young, as
the boys in the neighbourhood ride into the marsh every morning to
gather the eggs. The Gulls are, however, very tenacious of their old
breeding-places, and continue even after years of persecution to resort
to them.

The young birds are of a pale grey colour, mottled with dull brown, and
have a whining querulous cry. The plumage becomes lighter through the
autumn and winter, but it is not until the ensuing summer, when the dark
brown nuptial hood is assumed, that the young birds acquire the perfect
plumage--soft grey-blue above, and the white bosom with its lovely pink

As soon as the young are able to fly the breeding-place is forsaken, the
whole concourse leaving in a body, or scattering in all directions over
the surrounding country; and until the following summer their movements
depend entirely on food and water. If the weather is dry the Gulls
disappear altogether; and if grasshoppers become abundant the country
people wish for rain to bring the Gulls. When it rains then the birds
quickly appear, literally from the clouds, and often in such numbers as
to free the earth from the plague of devastating insects. It is a fine
and welcome sight to see a white cloud of birds settle on the afflicted
district; and at such times their mode of proceeding is so regular that
the flock well deserves the appellation of an army. They sweep down with
a swift graceful flight and settle on the earth with loud joyful cries,
but do not abandon the order of attack when the work of devouring has
begun. The flock often presents a front of over a thousand feet, with
a depth of sixty or seventy feet; all along this line of battle the
excited cries of the birds produce a loud continuous noise; all the
birds are incessantly on the move, some skimming along the surface with
expanded wings, others pursuing the fugitives through the air, while
all the time the hindmost birds are flying over the flock to alight in
the front ranks, so that the whole body is steadily advancing, devouring
the grasshoppers as it proceeds. When they first arrive they seem
ravenously hungry, and after gorging themselves they fly to the water,
where after drinking they cast up their food and then go back to renew
the battle.

In spring these Gulls come about the farms to follow the plough, filling
the new-made furrows from end to end, hovering in a cloud over the
ploughman's head and following at his heels, a screaming, fighting
crowd. When feeding they invariably keep up a great noise. Wilson's
expression in describing a northern species, that its cry "is like the
excessive laugh of a negro," is also descriptive of the language of
our bird. Its peculiar cry is lengthened at will and inflected a
thousand ways, and interspersed with numerous short notes, like excited
exclamations. After feeding they always fly to the nearest water to
drink and bathe their feathers, after which they retire to some open
spot in the neighbourhood where there is a carpet of short grass. They
invariably sit close together with their bills toward the wind, and
the observer will watch the flock in vain to see one bird out of this
beautiful order. They do not stand up to fly, but rise directly from a
sitting posture. Usually the wings are flapped twice or thrice before
the body is raised from the ground.

In some seasons in August and September, after a period of warm wet
weather, the larvæ of the large horned beetle rise to the surface,
throwing up little mounds of earth as moles do; often they are so
numerous as to give the plains, where the grass has been very closely
cropped, the appearance of being covered with mud. These insects afford
a rich harvest to the Spur-winged Lapwing (_Vanellus cayennensis_),
which in such seasons of plenty are to be seen all day diligently
running about, probing and dislodging them from beneath the fresh
hillocks. The Gulls, unprovided with a probing beak, avail themselves
of their superior cunning and violence to rob the Lapwings; and I have
often watched their proceedings for hours with the greatest interest.
Hundreds of Lapwings are perhaps visible running busily about on all
sides; near each one a Gull is quietly stationed, watching the movements
of its intended dupe with the closest attention. The instant a great
snow-white grub is extracted the Gull makes a rush to seize it, the
Lapwing flies, and a violent chase ensues. After a hundred vain
doublings the Plover drops the prize, and slopes toward the earth with
a disappointed cry; the pursuer checks his flight, hovers a moment
watching the grub fall, then drops down upon it, gobbles it up, and
hastens after the Lapwing to resume his watch.

Many of these Gulls haunt the estancias to feed on the garbage usually
found in abundance about cattle-breeding establishments. When a cow is
slaughtered they collect in large numbers and quarrel with the domestic
poultry over the offal. They are also faithful attendants at the
shepherd's hut; and if a dead lamb remains in the fold when the flock
goes to pasture they regale on it in company with the Chimango. The
great _Saladeros_, or slaughter-grounds, which were formerly close to
Buenos Ayres, are also frequented by hosts of these neat and beautiful
scavengers. Here numbers may be seen hovering overhead, and mingling
their excited screams with the bellowing of half-wild cattle and the
shouts of the slaughterers at their rough work; and at intervals,
wherever a little space is allowed them, dropping themselves on to the
ground, which reeks with blood and offal, and greedily snatching up
whatever morsels they can on the instant, and yet getting no stain or
speck on their delicate dress of lily-white and ethereal blue.

On the open pampas their curiosity and anger seems greatly excited at
the appearance of a person on foot; no sooner has the Gull spied him
than it sweeps toward him with a rapid flight, uttering loud indignant
screams that never fail to attract all of its fellows within hearing
distance. These all pass and repass, hovering over the pedestrian's
head, screaming all the time as if highly incensed, and finally retire,
joining their voices in a kind of chorus and waving their wings upwards
in a slow curious manner; but often enough, when they are almost out of
sight, they suddenly wheel about and hurry back screaming, with fresh
zeal, to go through the whole pretty but annoying performance again.

    on the nape and throat; tail and underparts white; mantle grey
    (darker than in _L. maculipennis_); primaries black, with small
    subapical white patches on first and second, and longer ones on the
    outer webs of third to fifth near the base; _underwing slate-grey_;
    bill, legs, and feet crimson to orange-red: length 16·0 to 17·0
    inches, wing 12·25.

_Hab._ South Brazil, Uruguay, and La Plata, also coast of Peru.

The Grey-capped Gull is found on the Rio de la Plata, and as far north
as Concepcion on the Uruguay in winter, where Mr. Barrows observed it in
immense flocks frequenting the "_Saladeros_."

Durnford gives us the subjoined account of this species:--"I have not
observed this bird to the south of Buenos Ayres, but have constantly
seen it from March to July to the north of the city. Unlike _Larus
maculipennis_, it never wanders inland, but frequents the shallow shores
of the La Plata, feeding on dead fish or offal, and flocking round the
fishermen when they are hauling their nets to get a share of the spoil.
As a rule, this species does not mix with _Larus maculipennis_, though
now and then they are seen together; but all the flocks or parties I
have observed when flying from one spot to another have always been
composed of birds of its own kind. Adults, after once attaining their
pearl-grey hood, never lose it, though in winter it becomes rather
lighter, and those with white heads are immature birds, which do
not attain their full plumage till after their second moult. I have
seen many birds throughout May and June of the present year with
well-defined dark grey hoods. Some specimens, when first killed, have
a delicate faint pink tinge on their underparts, also observed in _L.
maculipennis_, which, however, quickly fades after death. The colour of
the iris varies a good deal in different examples, being pale grey, grey
with a tinge of yellow, and grey with a tinge of light wood-brown. This
is probably attributable to age. The narrow rim of naked skin round the
eye is dark coral-red; legs and feet the same, but of a duller shade;
beak rather darker than the legs."



The Grebes, although perhaps more especially a development of the
Arctic lands, are sparingly represented all through the tropics, and
reappear in augmented numbers south of the Antarctic circle. Within the
Neotropical Region nine to eleven species are met with, of which five
are found inside our limits. Three of these are peculiar Patagonian
species, the other two are widely spread over America.

_Hab._ South America.

This fine Grebe is said by Buffon to be from Cayenne, but we have never
seen specimens from anywhere so far north. It was not obtained in Brazil
by Natterer or Burmeister, but Azara met with it in Paraguay.

This Grebe is called in the vernacular _Macás cornudo_--the first word
being the Indian generic name for the Grebes, while _cornudo_ signifies
horned, from the bird's habit of erecting, when excited, the feathers of
the nape in the form of a horn. The species is found throughout Eastern
Argentina, from its northern limits to Central Patagonia, where Durnford
found it common and resident. On the Rio Negro I found it abundant, and
it was formerly just as common along the Plata river, but owing to its
large size and the great beauty of its lustrous under plumage it is very
much sought after and is becoming rare.

It is impossible to make this Grebe leave the water, and when discovered
in a small pool it may be pursued until exhausted and caught with the
hand; yet it must occasionally perform long journeys on the wing when
passing from one isolated lake to another. Probably its journeys are
performed by night.

There is little diversity in the habits of Grebes, and only once have I
seen one of these birds acting in a manner which seemed very unusual.
This Grebe was swimming about and disporting itself in a deep narrow
pool, and showed no alarm at my presence, though I sat on the margin
within twenty-five yards of it. I saw it dive and come up with a small
fish about three inches long in its beak; after sitting motionless for a
little while, it tossed the fish away to a considerable distance with a
sudden jerk of its beak, and then at the instant the fish touched the
water it dived again. Presently it emerged with the same fish, but only
to fling it away and dive as before; and in this way it released and
recaptured it about fifteen times, and then, tired of play, dropped it
and let it escape.

Mr. Gibson has the following note on the breeding-habits of the Great
Grebe, as observed at Ajo, near the mouth of Rio de La Plata:--"_P.
major_ breeds about the end of August, placing its nest in the thickest
rushes of the swamp. The nest, built of wet water-weeds, is raised just
above the level of the water; and I have twice seen the sitting bird
hastily draw some weeds over the eggs before leaving them, on my
approach. The clutch consists of three; and these are of the usual Grebe
colour, generally much soiled and stained. They average 2-6/40 × 1-7/40,
the length sometimes presenting a variation of 9/40, even in eggs of the
same nest."

    length 11·5 inches, wing 4·7. _Female_ similar.

_Hab._ Antarctic America, north to Cordova.

Darwin obtained examples of this beautiful Grebe at Bahia Blanca, where,
he says, "it lives in small flocks in the salt-water channels extending
between the great marshes at the head of the harbour." Durnford procured
specimens on both visits to Chupat, where he found it common in the
lagoons in all the valleys. It is also found, though not so abundantly,
in the northern provinces of the Argentine Republic. White obtained a
single example at Cosquin, near Cordova, in September 1882.

    _Description._--(_Summer plumage._) Above brownish black, with dark

    with rufous; ear-coverts elongated, white at base with black tips,
    and more or less covering the downy white feathers of the sides of
    the head; outer half of primaries brownish grey, darker at tip;
    inner half and secondaries more or less pure white, some of the
    outer webs brownish or buff: beneath, neck and throat blackish
    brown, shading into chestnut, burned with dusky on the lower breast
    and rest of under surface. (_Winter plumage._) Above not so dark:
    beneath, throat white, neck dusky rufous; rest of under surface
    shining whitish buff, becoming dusky towards the vent. Whole length
    11·8 inches, wing 5·4.

_Hab._ Antarctic America, north to Cordova.

Rolland's Grebe is said by Durnford to be "common in almost every pool
and ditch" in Chupat. It is also common throughout Buenos Ayres, where
the native name for it is _Macasíto_.

Mr. Gibson gives the following details as to its
nesting-habits:--"_Podiceps rollandi_ nests during the latter half of
September and beginning of October. The nest is a slight construction
of water-weeds, floating on the surface of the water, and only kept
stationary by the surrounding rushes. Like _P. major_, it covers the
eggs before leaving them. Five is the largest clutch of eggs I have
taken; they are originally of a bluish-white colour, but after some time
become covered with a brown incrustation of a chalky nature. The average
measurement is 1-30/40 × 1-9/40; but there is a variation of 11/40 in
length and 7/40 in breadth between my largest and smallest specimens."

Specimens of this Grebe were obtained near Cordova by White in 1882.

This representative of the well-known "Dabchick" of Europe is found
throughout South and Central America. In the Argentine Republic, near
Buenos Ayres, it is "resident and common in the lagoons and arroyos"
(Durnford, _l. s. c._), and likewise in the Territory of Chupat.

_Hab._ North and South America.

The Thick-billed Grebe extends all through America, from Canada down
to Patagonia and Chili. It does not seem to have been noticed in the
Argentine Republic except by Mr. Withington, who sends us a single
specimen from the Lomas de Zamora, near Buenos Ayres.

A second and larger species of this genus (_P. antarcticus_) occurs on
the western side of America from Guatemala to Chili.



The Penguins are a peculiar group of oceanic birds which differ
essentially from all other birds in the construction of their wings and
feet, and should certainly form an Order apart. They are denizens of the
Antarctic sea-shores and islands, but in the Pacific go as far north as
the Galapagos. On the shores and islands of South America nine species
occur, one of which has been met with within our limits.

_Hab._ Coasts of Antarctic America and Falkland Islands.

At the mouth of the Rio Negro Hudson once picked up a specimen of a
Penguin, believed to have been of this species, which had apparently
just met its death by some accident. The range of this bird, moreover,
appears to extend much further north, as it is well known to the Gauchos
along the coast, who call it "_Pajaro Niño_" (bird boy), from its
fancied resemblance to a small human being when it stands erect on the

Darwin (Nat. Voy. chap. iii.) speaks of having seen numerous Penguins in
the estuary of the Rio de la Plata, when approaching Monte Video in
the 'Beagle,' in July 1832; and Graf v. Berlepsch tells me he has an
imperfect specimen of _Spheniscus magellanicus_ from the coast of Rio
Grande do Sul, where it was picked up dead.

The "Jackass Penguin" is a well-known species in the Falkland Islands,
to which it resorts in thousands for the purpose of breeding. Capt.
Abbott tells us it arrives at the latter end of September and commences
laying in its breeding-holes, almost to a day, on October 17. Some of
these birds, however, are found on the shores of the Falkland Islands
throughout the year.



The Tinamous constitute one of the most singular and characteristic
types of the Neotropical avifauna. Until late years they were usually
associated with the Gallinæ or Game Birds, but differ very widely from
them in the conformation of the skull and in other essential points of
structure, and are now generally regarded as forming an Order of their
own, to be placed at the base of the series of Carinatæ. About forty
species of Tinamous are known, of which eight occur within our limits.

White refers a Tinamou which he shot at Oran in November 1880 to
_Crypturus cinereus_. There can be little doubt, however, that the
specimen in question really belonged to the allied species _C.
obsoletus_, which is known to occur in Paraguay. The true _C. cinereus_
is from a much more northern locality, and is not likely to be found
in Argentina.

    1·8. _Female_ similar.

_Hab._ South Brazil, Paraguay, and Northern Argentina.

The Tataupa Tinamou was first described by Azara as an inhabitant of
Paraguay, whence it extends into the northern provinces of the Argentine
Republic. White obtained specimens among the undergrowth in the dense
forests of Campo Colorado, near Oran, and Durnford also met with it near

To Azara's interesting account of the Tataupa's habits nothing has been
recently added. He says that this species inhabits woods and thickets,
and also approaches houses where it finds cover--hence the Guarani name,
which means a bird of the house. It lays four eggs of a fine purple
colour; and when driven from the nest flutters along the ground,
feigning lameness. It sings all the year round, and for power and
brilliance of voice is preeminent among this class of birds. After the
first note of its curious song there is an interval of eight seconds of
silence; then the note is repeated with shorter and shorter intervals,
until, becoming hurried, they run into a trill, followed by a sound
which may be written _chororó_, repeated three or four times. When
sitting close it tips forward, pressing its breast on its legs, so
that the rump is raised higher than the back, and opening the terminal
feathers of the body, it spreads them in a semicircle over the back
as if to conceal itself beneath them, and when looked at from behind
nothing is visible except this fan of feathers. The feathers are concave
with points inclining upward, and when thus disposed have a strange and
beautiful appearance.

    _Description._--Above cinereous; head, wings, and back crossed by
    black bars with pale ochraceous edgings; neck reddish; primaries
    chestnut: beneath pale cinereous, strongly tinged with rufous on the
    neck and breast; chin white; bill ashy, beneath at base yellowish;

    3·0. _Female_ similar, but larger.

_Hab._ South Brazil, Paraguay, and Argentina.

This large Tinamou, known to the Argentines as the _Perdiz grande_, or
"Great Partridge," is found on the pampas wherever long grasses abound,
and extends as far south as the Colorado river, its place being taken
in Patagonia by _Calodromas elegans_. It is never met with in woods or
thickets, and requires no shelter but the giant grasses, through which
it pushes like a Rail. Wherever the country becomes settled and the
coarse indigenous grasses are replaced by those of Europe, it quickly
disappears, so that it is already extinct over a great portion of the
Buenos Ayrean pampas.

This species is solitary in its habits, conceals itself very closely in
the grass, and flies with the greatest reluctance. I doubt if there is
anywhere a bird with such a sounding flight as the Tinamou; the whir
of its wings can only be compared to the rattling of a vehicle driven
at great speed over a stony road. From the moment it rises until it
alights again there is no cessation in the rapid vibration of the wings;
but, like a ball thrown by the hand, the bird flies straight away
with extraordinary violence until the impelling force is spent, when
it slopes gradually towards the earth, the distance it is able to
accomplish at a flight being from 800 to 1500 yards. This flight it can
repeat when driven up again as many as three times, after which the bird
can rise no more.

The call of the Large Partridge is heard, in fine weather, at all
seasons of the year, especially near sunset, and is uttered while the
bird sits concealed in the grass, many individuals answering each other;
for although I call it a solitary bird, it being a rare thing to see
even two together, many birds are usually found living near each other.
The song or call is composed of five or six notes of various length,
with a mellow flute-like sound, and so expressive that it is, perhaps,
the sweetest bird-music heard on the pampas.

The eggs are usually five in number, nearly round, highly polished, and
of a dark-reddish-purple or wine colour; but this beautiful tint in a
short time changes to a dull leaden hue. The nest is a mere scrape,
insufficiently lined with a few grass-leaves. The young birds appear to
leave the mother (or father, for it is probable that the male hatches
the eggs) at a very early period. When still very small they are found
living, like the adults, a solitary life, with their facilities,
including those of flight and the melodious voice, in a high state of

We have been able to compare a typical specimen of _Nothoprocta
doeringi_, received from Dr. Doering of Cordova, with the series of
specimens of this group in the British Museum, and find that Dr.
Cabanis's name must give way to G. R. Gray's prior designation. Dr.
Doering's specimens of this species were obtained in the Sierra de
Cordova. The original example of _Nothoprocta pentlandi_ was procured
by Pentland, the well-known scientific traveller (after whom it is
called), in the Andes of Bolivia.

This fine and distinct species was first obtained by Dr. Burmeister in
Cordova and in Tucuman, where Durnford also obtained specimens of it
during his last journey. It is larger than _N. pentlandi_, and has the
breast thickly covered by somewhat rounded light spots upon a cinereous
ground; these are mixed with black points and slight striations.

_Hab._ Argentine Republic.

The _Perdiz comun_ or Common Partridge of the pampas, as it is always
called--the naturalist's name of Tinamou being utterly unknown in
the southern part of South America--is much smaller than the "Perdiz
grande," but in its form, slender curved beak, bare legs, and in the
yellowish mottled plumage generally resembles it. It also inhabits the
same kind of open grassy country, and is abundant everywhere on the
pampas and as far south as the valley of the Rio Negro in Patagonia. It
is solitary; but a number of individuals are usually found in proximity;
and in lonely places on the pampas, where they are excessively abundant,
I have seen three or four meet together and play in the manner of
kittens, darting out from a place of concealment at each other, the
pursued bird always escaping by turning off at right angles or by
suddenly crouching down and allowing the pursuer to spring over it.

It is very tame in disposition, and flies so reluctantly that it is not
necessary to shoot them where they are very abundant, as any number
can be killed with a long whip or stick. It moves on the ground in a
leisurely manner, uttering as it walks or runs a succession of low
whistling notes. It has two distinct songs or calls, pleasing to the ear
and heard all the year round; but with greater frequency in spring, and,
where the birds are scarce and much persecuted, in spring only. One is a
succession of twenty or thirty short impressive whistling notes of great
compass, followed by half a dozen rapidly uttered notes, beginning loud
and sinking lower till they cease: the other call is a soft continuous
trill, which appears to swell mysteriously on the air, for the listener
cannot tell whence it proceeds; it lasts several seconds, and then seems
to die away in the distance.

It is an exceedingly rare thing to see this bird rise except when
compelled. I believe the power of flight is used chiefly, if not
exclusively, as a means of escape from danger. The bird rises up when
almost trodden upon, rushing into the air with a noise and violence that
fill one with astonishment. It continues to rise at a decreasing angle
for fifty or sixty yards, then gradually nears the earth, till, when it
has got to a distance of two or three hundred yards, the violent action
of the wing ceases, and the bird glides along close to the earth for
some distance, and either drops down or renews its flight. I suppose
many birds fly in much the same way; only this Tinamou starts forward
with such amazing energy that, until this is expended and the moment of
gliding comes, the flight is just as ungovernable to the bird as the
motion of a brakeless engine, rushing along at full speed, would be to
the driver. The bird knows the danger to which this peculiar character
of its flight exposes it so well, that it is careful to fly only to that
side where it sees a clear course. It is sometimes, however, compelled
to take wing suddenly, without considering the obstacles in its path; it
also often miscalculates the height of an obstacle, so that for Tinamous
to meet with accidents when flying is very common. In the course of a
short ride of two miles, during which several birds sprang up before me,
I have seen three of these Tinamous dash themselves to death against
a fence close to the path, the height of which they had evidently
misjudged. I have also seen a bird fly blindly against the wall of a
house, killing itself instantly. A brother of mine told me of a very
curious thing he once witnessed. He was galloping over the pampas, with
a very violent wind blowing in his face, when a Tinamou started up
before his horse. The bird flew up into the air vertically, and, beating
its wings violently, and with a swiftness far exceeding that of its
ordinary flight, continued to ascend until it reached a vast height,
then came down again, whirling round and round, striking the earth a
very few yards from the spot where it rose, and crushing itself to a
pulp with the tremendous force of the fall. It is very easy to guess the
cause of such an accident: while the Tinamou struggled blindly to go
forward, the violent wind, catching the under surface of the wings,
forced it upwards, until the poor bird, becoming hopelessly confused,
fell back to earth. I have often seen a swallow, gull, or hawk, soaring
about in a high wind, suddenly turn the under surface of its wings to
the wind and instantly shoot straight up, apparently without an effort,
to a vast height, then recover itself, and start off in a fresh
direction. The Tinamou, when once launched on the atmosphere, is at
the mercy of chance; nevertheless, had this incident been related to me
by a stranger, I should not have recorded it.

This Tinamou is frequently run down and caught by well-mounted Gaucho
boys; the bird frequently escapes into a kennel in the earth, but when
it sees no refuge before it and is hotly pursued, it sometimes drops
dead. When caught in the hand they "feign death" or swoon, but on being
released quickly recover their faculties.

The nest is a slight hollow scratched in the ground under a thistle or
in the grass, and lined with a few dry leaves. The number of eggs laid
varies from five to eight. These are elliptical, with polished shells,
and as a rule are of a wine-purple colour; but the hue varies somewhat,
some eggs having a reddish tinge and others a deep liver-colour.

_Hab._ Northern Patagonia.

This species, called _Perdiz chico_ by the natives, is somewhat smaller
and paler in colouring than the common Tinamou of the pampas, but very
closely resembles the young of that species. It inhabits Patagonia,
and is nowhere very numerous, but appears to be thinly and equally
distributed on the dry sterile plains of that region, preferring places
abounding in thin scrub. In disposition it is extremely shy, and when
approached springs up at a distance ahead and runs away with the
greatest speed and apparently much terrified. Sometimes when thus
running it utters short whistled notes like the allied species. It rises
more readily and with less noise than the pampas bird, and has a much
higher flight. It has one call-note, heard only in the love-season--a
succession of short whistling notes, like those of the _N. maculosa_,
but without the rapidly uttered conclusion.

The nest is made under a small scrubby bush, and contains from five to
seven eggs, in form and colour like those of _N. maculosa_, except that
the reddish-purple tint is paler.

    vertical crest of black feathers, partly edged with cinereous; two
    lateral stripes on the head above and beneath the eye and throat

_Hab._ Northern Patagonia and Western Argentina.

This fine game bird in its size and mottled plumage resembles the
_Rhynchotus rufescens_ of the pampas, which it represents in the
Patagonian district south of the Rio Colorado. It differs externally in
the more earthy hue of its plumage, which is protective and harmonizes
admirably with the colour of its sterile surroundings; also in having a
shorter beak, and in being adorned with a long slender black crest,
which, when excited, the bird carries directed forwards like a horn.
There is, however, an anatomical difference, which seems to show that
the two species are not very near relations. The structure of the
intestinal canal in the Martineta is most peculiar, and unlike that of
any other bird I have ever dissected: the canal divides near the stomach
into a pair of great ducts which widen towards the middle and extend
almost the entire length of the abdominal cavity, and are thickly set
with rows of large membranous claw-shaped protuberances.

The Martineta inhabits the elevated tablelands, and is found chiefly
where patches of scattered dwarf scrub occur among the thorny thickets.
Apparently they do not require water, as they are met with in the driest
situations where water never collects. They are extremely fond of
dusting themselves, and form circular, nest-like hollows in the ground
for that purpose; these hollows are deep and neatly made, and are
visited every day by the same birds throughout the year. They live
in coveys of from half a dozen to twenty or thirty birds, and when
disturbed do not as a rule take to flight at once, but jump up one
after another and run away with amazing swiftness, uttering as they run
shrill, squealing cries, as if in the greatest terror. Their flight,
although violent, is not so sounding as that of the Pampas Tinamou
(_Rhynchotus_), and differs remarkably in another respect. Every twenty
or thirty yards the wings cease beating and remain motionless for a
second, when the bird renews the effort; thus the flight is a series of
rushes rather than a continuous rush like that of the _Rhynchotus_. It
is also accompanied with a soft wailing note, which appears to die away
and swell again as the flapping of the wings is renewed.

The call-note of the Martineta is never heard in winter; but in the
month of September they begin to utter in the evening a long, plaintive,
slightly modulated whistle, the birds sitting concealed and answering
each other from bush to bush. As the season advances the coveys break
up, and their call is then heard on every side, and often all day long,
from dawn until after dark. The call varies greatly in different birds,
from a single whistle to a performance of five or six notes, resembling
that of _Rhynchotus_, but inferior in compass and sweetness. They begin
to breed in October, making the nest in the midst of a small isolated
bush. The eggs vary in number from twelve to sixteen; they are
elliptical in form, of a beautiful deep green in colour, and have
highly polished shells.

It is probable, I think, that this species possesses some curious
procreant habits, and that more than one female lays in each nest; but
owing to the excessive wariness of the bird in a state of nature it is
next to impossible to find out anything about it. No doubt the day will
come when naturalists will find the advantage of domesticating the birds
the life-histories of which they wish to learn: may it come before all
the most interesting species on the globe are extinct!



The Order of Struthious Birds or Ostriches is represented in South
America by the Nandu or Rhea, which is at once distinguished from the
African Ostrich (_Struthio_) by having three toes instead of two, as
also by many other important points of structure.

Both the known species of _Rhea_ are found within our limits.

_Hab._ Pampas of S. America north of Rio Negro.

The Common Rhea (called "_Ñandú_" in the Guarani language, "_Chueké_" by
the pampas Indians, and "Ostrich" by Europeans) is found throughout
the Argentine Republic down to the Rio Negro in Patagonia, and,
in decreasing numbers, and associating with Darwin's Rhea, to a
considerable distance south of that river. Until within very recent
times it was very abundant on the pampas, and I can remember the
time when it was common within forty miles of Buenos Ayres city. But
it is now becoming rare, and those who wish to have a hand in its
extermination must go to a distance of three or four hundred miles from
the Argentine capital before they can get a sight of it.

The Rhea is peculiarly well adapted, in its size, colour, faculties, and
habits, to the conditions of the level woodless country it inhabits; its
lofty stature, which greatly exceeded that of any of its enemies before
the appearance of the European mounted hunter, enables it to see far;
its dim grey plumage, the colour of the haze, made it almost invisible
to the eye at a distance, the long neck being so slender and the bulky
body so nearly on a level with the tall grasses; while its speed
exceeded that of all other animals inhabiting the same country. When
watching the chase of Ostriches in the desert pampas, abounding in giant
grasses, it struck me forcibly that this manner of hunting the bird on
horseback had brought to light a fault in the Rhea--a point in which the
correspondence between the animal and its environment is not perfect.
The Rhea runs smoothly on the surface, and where the tall grass-tussocks
are bound together, as is often the case, with slender twining plants,
its legs occasionally get entangled, and the bird falls prostrate, and
before it can struggle up again the hunter is close at hand and able to
throw the _bolas_--the thong and balls, which, striking the bird with
great force, wind about its neck, wings, and legs, and prevent its
escape. When I questioned Ostrich-hunters as to this point they said
that it was true that the Rhea often falls when running hotly pursued
through long grass, and that the deer (_Cervus campestris_) never falls
because it leaps over the large tussocks and all such obstructions. This
small infirmity of the Rhea would not, however, have told very much
against it if some moderation had been observed in hunting it, or if the
Argentine Government had thought fit to protect it; but in La Plata, as
in North America and South Africa, the licence to kill, which every one
possesses, has been exercised with such zeal and fury that in a very few
more years this noblest Avian type of the great bird-continent will be
as unknown on the earth as the Moa and the _Æpyornis_.

The Rhea lives in bands of from three or four to twenty or thirty
individuals. Where they are not persecuted they show no fear of man, and
come about the houses, and are as familiar and tame as domestic animals.
Sometimes they become too familiar. At one _estancia_ I remember an old
cock-bird that constantly came alone to feed near the gate, and that had
so great an animosity against the human figure in petticoats, that the
women of the house could not go out on foot or horseback without a man
to defend them from its attacks. When the young are taken from the
parent bird they become, as Azara truly says, "domestic from the first
day," and will follow their owner about like a dog. It is this natural
tameness, together with the majesty and quaint grace of its antique
form, which makes the destruction of the Rhea so painful to think of.

When persecuted, Rheas soon acquire a wary habit, and escape by running
almost before the enemy has caught a sight of them; or else crouch down
to conceal themselves in the long grass; and it then becomes difficult
to find them, as they lie close, and will not rise until almost trodden
on. Their speed and endurance are so great that, with a fair start,
it is almost impossible for the hunter to overtake them, however well
mounted. When running, the wings hang down like those of a wounded bird,
but usually one wing is raised and held up like a great sail, for what
reason it is impossible to say. When hard pressed, the Rhea doubles
frequently and rapidly at right angles to its course; and if the
pursuer's horse is not well trained to follow the bird in all its
sudden turns without losing ground he is quickly left far behind.

In the month of July the love-season begins, and it is then that the
curious ventriloquial bellowing, booming, and wind-like sounds are
emitted by the male. The young males in the flock are attacked and
driven off by the old cock-bird; and when there are two old males they
fight for the hens. Their battles are conducted in a rather curious
manner, the combatants twisting their long necks together like a couple
of serpents, and then viciously biting at each other's heads with their
beaks; meanwhile, they turn round and round in a circle, pounding the
earth with their feet, so that where the soil is wet or soft they make
a circular trench where they tread. The females of a flock all lay
together in a natural depression in the ground, with nothing to shelter
it from sight, each hen laying a dozen or more eggs. It is common to
find from thirty to sixty eggs in a nest, but sometimes a larger number,
and I have heard of a nest being found containing one hundred and twenty
eggs. If the females are many the cock usually becomes broody before
they finish laying, and he then drives them with great fury away and
begins to incubate. The hens then drop their eggs about on the plains;
and from the large number of wasted eggs found it seems probable that
more are dropped out of than in the nest. The egg when fresh is of a
fine golden yellow, but this colour grows paler from day to day, and
finally fades to a parchment-white.

After hatching, the young are assiduously tended and watched over by the
cock, and it is then dangerous to approach the Rhea on horseback, as the
bird with neck stretched out horizontally and outspread wings charges
suddenly, making so huge and grotesque a figure that the tamest horse
becomes ungovernable with terror.

Eagles and the large Polyborus are the enemies the Rhea most fears when
the young are still small, and at the sight of one flying overhead he
crouches down and utters a loud snorting cry, whereupon the scattered
young birds run in the greatest terror to shelter themselves under his

_Hab._ Patagonia south of the Rio Negro.

Darwin's Rhea inhabits Patagonia from the Straits of Magellan to the
Rio Negro, and is also met with occasionally north of that river. The
Indians call it "Molú Chueké"--short or dwarf Chueké; its Spanish name
is "_Avestruz petizo_." They were formerly very abundant along the Rio
Negro; unhappily, some years ago their feathers commanded a very high
price; Gauchos and Indians found that hunting the Ostrich was their most
lucrative employment; consequently these noble birds were slaughtered
in such numbers that they have been almost exterminated wherever the
nature of the country admits of their being chased. When on the Rio
Negro in 1871 I was so anxious to obtain specimens of this Rhea that I
engaged several Indians by the offer of a liberal reward to hunt for me,
but they failed to capture a single adult bird. I can only set down here
the most interesting facts I was able to collect concerning its habits,
which are very imperfectly known.

When pursued it frequently attempts to elude the sight by suddenly
squatting down amongst the bushes, which have a grey foliage, to which
the colour of its plumage closely assimilates. When hard pressed it
possesses the same habit as the Common Rhea of raising the wings
alternately and holding them up vertically; and also doubles suddenly
like that species. Its speed is greater than that of the Common Rhea,
but it is sooner exhausted. In running it carries its neck stretched
forward almost horizontally, which makes it seem lower in stature than
the allied species,--hence the vernacular name of "short Ostrich." It
is found in flocks of from three or four to thirty or more individuals.
It begins to lay at the end of July, that is a month before the _Rhea
americana_. Several females lay in one nest, which is merely a slight
depression lined with a little dry rubbish; as many as fifty eggs are
sometimes found in one nest. A great many wasted or _huacho_ eggs, as
they are called, are also found at a distance from the nest. I examined
a number of eggs brought in by the hunters, and found them vary greatly
in shape, size, and colour. The average size of the eggs was the same as
those of the Common Rhea; in shape they were more or less elliptical,
scarcely any two being precisely alike. The shell has a fine polish, and
when newly laid the colour is deep rich green. They soon fade, however,
and the side exposed to the sun first assumes a dull mottled green; then
this colour fades to yellowish, and again to pale stone-blue, becoming
at last almost white. The comparative age of each egg in the nest may
be known by the colour of the shell. The male incubates and rears the
young; and the procreant habits seem altogether like those of _Rhea

The young are hatched with the legs feathered to the toes; these
leg-feathers are not shed, but are gradually worn off as the bird grows
old by continual friction against the stiff scrubby vegetation. In
adults usually a few scattered feathers remain, often worn down to mere
stumps; but the hunters told me that old birds are sometimes taken with
the legs entirely feathered, and that these birds frequent plains where
there is very little scrub. The plumage of the young is dusky grey,
without white and black feathers. When a year old they acquire by
moulting the mottled plumage of the adults, but do not attain their
full size until the third year.

Although this celebrated work relates mainly to the neighbouring State
of Paraguay, so many birds are common to Paraguay and La Plata that it
has of course a most important bearing on the Ornithology of the latter
country. Azara, unfortunately, gave only Spanish names to his birds,
so that the Latin titles of them are mostly those of Vieillot, who
translated Azara's remarks and gave scientific names to his birds in
different volumes of the 'Nouveau Dictionnaire d'Histoire Naturelle'
(Paris, 1816-19). A most useful Index to Azara's 'Apuntamientos' was
published in 1847 by Dr. G. Hartlaub of Bremen[11]. A more modern
_résumé_ of the Birds of Paraguay, in which much information is
contained, has been recently written by Hans, Graf v. Berlepsch[12].

In a work on Argentine Ornithology it is hardly necessary to explain
who Dr. Burmeister is. The Director of the Museo Publico is as well
known in Europe as he is in Buenos Ayres. It should, however, be
here mentioned that in the second volume of 'Reise durch die La
Plata-Staaten' Dr. Burmeister has given an excellent systematic synopsis
of the Vertebrate Animals of the Argentine Republic. Of the class of
Birds 263 species are enumerated as having been met with within the
limits of the Republic up to that date, and references, native names,
and general observations as to habits and localities are attached to
each species. This is in fact up to the present time the best, or, we
might say, the only authority on the Birds of the Argentine Republic.

Besides this, Dr. Burmeister has published several other contributions
towards our knowledge of Argentine Ornithology, namely:--

Darwin, when Naturalist to the 'Beagle,' during her voyage round the
world in 1832-6, made good collections of birds on the Rio de la Plata
and along the shores of Patagonia. Most of his specimens, originally
deposited in the Zoological Society's Museum, are now in the British
Museum, but some of them unfortunately are in a very imperfect
condition. His valuable notes were published in the work of which the
title is above given. They relate to about 80 species of Argentine
Birds. The specimens were determined and the new species described by
Gould; but Gould's MS. was afterwards revised for publication by G. R.
Gray, on account of Gould's absence in Australia.

Darwin's 'Naturalist's Voyage,' originally published as a volume of the
Narrative of the 'Voyage of the Beagle,' also contains many excellent
notes on the life and habits of Argentine Birds.

      los meses de Abril, Mayo y Junio de 1879, bajo las órdenes del
      General D. Julio A. Roca. Entrega I. Zoología. Buenos Aires,

Dr. Adolf Doering, of the Argentine University of Cordoba, has been a
zealous collector and observer of the birds of the Republic (see under
Cabanis and Sclater). The zoological portion of his report upon the Rio
Negro expedition of 1879 gives a list of the birds, which contains 110
species, most of them well-known Patagonian forms.


Henry Durnford, a member of the British Ornithologists' Union, whose
early decease was a severe loss to ornithological science, was a
constant worker on birds from the time of his arrival in Buenos Ayres in
1875 until his death in 1878. The birds collected by Durnford are now
mostly in the British Museum. His published papers on this subject are
the following (see also biographical notice in 'Ibis,' 1879, p. 121):--

  (1) Ornithological Notes from the Neighbourhood of Buenos Ayres.
      Ibis, 1876, p. 157.

[Notes made during his first five months' residence at Belgrano, five
miles north-west of Buenos Ayres. About 70 species are mentioned.]

  (2) Notes on the Birds of the Province of Buenos Ayres. Ibis, 1877,
      p. 166, and 1878, p. 58.

[Notes made principally at Baradero, 90 miles W.N.W. of Buenos Ayres.
In the first paper 144 species are mentioned and _Porzana spiloptera_
is described and figured as new. In the second 47 species, mostly
additional, are noticed.]

  (3) Notes on some Birds observed in the Chupat Valley, Patagonia, and
      in the Neighbouring District. Ibis, 1877, p. 27.

[Durnford first visited Chupat, on the river of the same name, in
Eastern Patagonia (43° 20′ S. lat.), in October 1876; 62 species of
birds are noted and commented upon.]

  (4) Notes on the Birds of Central Patagonia. Ibis, 1878, p. 389.

[Durnford's second visit to Chupat extended from September 1877 to April
1878. The list of birds is now extended to 89, and it is not believed
that many more will be found to occur in the district.]

  (5) Last Expedition to Tucuman and Salta. Ibis, 1880, p. 411, pl.

[This is an almost verbatim copy of Durnford's journal in 1878, during
his expedition to Tucuman and Salta. Many notes on birds are inserted.
Durnford died at Campo Santo, in the province of Salta, on July 13th,
1878. The collection made on this occasion was worked out by Mr. Salvin
(Ibis, 1880, p. 351, see below).]


Mr. Ernest Gibson, who has been resident in the Argentine Republic since
about 1873, is an excellent observer in the field, and has written
two very interesting papers on our subject, from which we have quoted
largely in this work.

  (1) Ornithological Notes from the Neighbourhood of Cape San Antonio,
      Buenos Ayres. Ibis, 1879, p. 405; 1880, pp. 1, 153.

Mr. Gibson's notes, which relate to 61 species, are in most cases very
full and contain particulars of the breeding-habits, eggs, and nests.
Cape San Antonio is on the Atlantic coast, south of Buenos Ayres (36°
20′ S. lat.).

  (2) Notes on the Birds of Paisandú, Republic of Uruguay.
      (Communicated by J. J. Dalgleish.) Ibis, 1885, p. 275.

Field-notes on 52 species from this locality, which Mr. Gibson visited
in 1883. The specimens were sent to Mr. J. J. Dalgleish and named by P.
L. S.

GIEBEL, Prof. C. (of Halle, Germany).

  Einige neue und wenig bekannte argentinische Vögel. Zeitschr. f. d.
      ges. Naturwiss. xxxi. p. 11 (1868).

In this paper the author described two new Bolivian species and two
Argentine species (_Troglodytes fasciolatus_ and _Geobamon rufipennis_),
from specimens in the Halle Museum received from Dr. Burmeister.


Gould determined the species in the collection made by Darwin during the
voyage of the 'Beagle,' and drew up the scientific portion of the report
on the birds, which forms vol. iii. of the "Zoology" of the voyage.
Owing to his departure for Australia the MS. was subsequently completed
and edited by G. R. Gray (see DARWIN, C.).

      Córdoba, v. pp. 73-92.

[Seventy-nine species of birds are given as occurring in the Sierra of
Tandil, south of Buenos Ayres, and slight field-notes are added.]


My fellow-author of the present work, though English in name and origin
and now resident in London, is an Argentine citizen by birth. From his
early childhood he was an observer of bird-life in the province of
Buenos Ayres, and continued his investigations until he left the country
for England a few years ago. Besides the pampas he explored the woods
and marshes along the Plata, and the range of the Sierras from Cape
Corrientes on the Atlantic to the Azul and Tapalquen, and made an
expedition to the Rio Negro in 1871.

The following is a list of his scientific papers on this subject, which
are mostly incorporated in the present work:--

myself and Salvin.


Dr. Leybold was resident in Santiago, Chili, for some years, and sent
bird-skins and other objects of natural history to Munich for sale in
Europe. He published two papers on supposed new birds obtained by his
collectors during their excursions from Chili to Mendoza.

  (1) Beschreibung von vier neuen Vogelarten aus der Argentinischen
      Provinz Mendoza. Journ. f. Orn. 1865, pp. 401-406.

_Sporophila rufirostris_, and _Phrygilus ornatus_, from Mendoza. These
species are all referred to in our work.]

San Luis (=_Conurus acuticaudatus_), _Colaptes leucofrenatus_
(=_Chrysoptilus cristatus_), and _Columbina aurisquamata_ (=_Metriopelia

After Azara's 'Apuntamientos' this is the most important of the older
publications relating to Argentine ornithology. The celebrated French
traveller and naturalist d'Orbigny made extensive collections of birds
in several parts of the Argentine Republic, especially in Corrientes,
on the Paraná, near Buenos Ayres, and on the Rio Negro. The birds were
worked out by himself after his return home, with the assistance of the
well-known French ornithologist the Baron F. de la Fresnaye. The list
of them, with the descriptions of the new species, was first published
in two consecutive volumes of the 'Magasin de Zoologie' (for 1837
and 1838), with a separate title[13] and separately paged. It was
unfortunately never completed, and contains only the Accipitres,
Passeres, and Picariæ. The valuable notes and remarks of d'Orbigny were
subsequently published in the fourth volume of his 'Voyage,' of which
the title is given above. This work also, as is much to be regretted,
was brought to a sudden termination when only half finished.

  [13] Synopsis avium ab Alcide d'Orbigny in ejus per Americam
  meridionalem itinere collectarum et ab ipso viatore necnon A. de la

D'Orbigny's types are now mostly in the French National Collection at
Paris, though a few of them, which cannot be found there, are supposed
to have been retained in the De la Fresnaye Collection, and if so are
now in the museum of the Boston Society of Natural History.

      Expedition to Tucuman and Salta. Ibis, 1880, p. 351.

The collection consisted of 84 specimens belonging to 54 species,
obtained in June 1878 at Tucuman or near Salta. Nine were new to Dr.
Burmeister's list. See also DURNFORD, _suprà_, p. 224.


Herr Fritz Schulz, an assistant in the museum of the University of
Cordoba, brought a fine collection of birds to Europe in 1883, which he
had made in Tucuman and other northern provinces of the Republic. The
new species were described by Dr. Cabanis (see above, p. 223), except a
single species described by Schulz himself.

examples of 92 species, of which 33 were additional to those contained
in the two former lists. Thus the total number of species of the
district of Quilmes is raised to 143.]


Herr Weisshaupt was a German collector at Santiago, Chili, who came
several times to London with fine collections of living animals (see P.
Z. S. 1870, p. 664, and 1871, p. 700). He made one or more excursions to
Mendoza from Santiago, and collected bird-skins in the vicinity of that
city. Many of these skins were acquired by Messrs. Salvin and Godman and
myself respectively and are in our collections.


Ernest William White was another active worker in Argentine ornithology,
whose untimely death we have lately had occasion to deplore[14]. During
five years' journeyings in the northern provinces of the Republic White
made very extensive collections and accumulated a mass of excellent
notes, which are published in the following papers:--
