About This Book

This work offers a systematic descriptive catalogue of the non-passerine birds recorded from the Argentine Republic, completing accounts of orders, families and species omitted from the first volume. Each entry provides identification details, geographic distribution, and behavioral notes contributed by a companion naturalist; many species are illustrated with color plates and diagnostic woodcuts. A comprehensive appendix and index conclude the volume. Together with the companion volume the authors enumerate and comment on the avifauna they recognize, and they highlight regions where further provincial exploration may add species.

Description.—Above ferruginous; top of head black; superciliaries and band beneath the eye with chin and cheeks whitish, with black freckles; wings brown, with a large white patch on the secondaries; tail black; abdomen dirty white, sprinkled with rufous; axillaries pure white; bill bluish; feet black: whole length 13·0 inches, wing 5·5, tail 3·8. Female: brownish black, back spotted with buffy; sides of head and body beneath ochraceous, with black cross bands.

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.


Order XI. COLUMBÆ.

Fam. XLI. COLUMBIDÆ, or PIGEONS.

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 Ornis.

357. COLUMBA PICAZURO, Temm.
(PICAZURO PIGEON.)

Patagiœnas maculosa, Burm. La-Plata Reise, ii. p. 496 (Mendoza, Cordova, Tucuman). Columba picazuro, Scl. et Salv. Nomencl. p. 132; iid. P. Z. S. 1868, p. 143 (Buenos Ayres); Durnford, Ibis, 1877, p. 193 (Buenos Ayres); Gibson, Ibis, 1880, p. 6 (Buenos Ayres); Barrows, Auk, 1884, p. 274 (Entrerios).

Description.—Above pale brown; head and neck vinous; back of neck with white cross bands which are edged with black; lower back and tail plumbeous; wings plumbeous, larger coverts broadly edged with white: beneath pale vinaceous; flanks and crissum plumbeous: whole length 14·0 inches, wing 8·0, tail 4·5. Female similar.

Hab. S.E. Brazil, Paraguay, and Argentina.

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.

358. COLUMBA MACULOSA, Temm.
(SPOT-WINGED PIGEON.)

Columba maculosa, Scl. et Salv. Nomencl. p. 132; Sclater, P. Z. S. 1872, p. 545 (Rio Negro); Durnford, Ibis, 1877, p. 42 (Chupat), et 1878, p. 401 (Centr. Patagonia); White, P. Z. S. 1882, p. 626 (Catamarca); Barrows, Auk, 1884, p. 274 (Entrerios).

Description.—Above pale vinaceous brown, profusely spotted on the back and wings with white apical spots; lower back and tail plumbeous; wings and tail slaty black, the former with narrow whitish margins: beneath plumbeous, with a strong vinaceous tinge; bill black; feet yellow: whole length 13·0 inches, wing 8·5, tail 4·5. Female similar.

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 Wood-Pigeon.

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.

359. ZENAIDA MACULATA (Vieill.).
(SPOTTED DOVE.)

Zenaida maculata, Burm. La-Plata Reise, ii. p. 497; Scl. et Salv. Nomencl. p. 132; iid. P. Z. S. 1868, p. 143 (Buenos Ayres); Durnford, Ibis, 1877, p. 193 (Buenos Ayres); Gibson, Ibis, 1880, p. 8 (Buenos Ayres); White, P. Z. S. 1882, p. 626 (Catamarca); Barrows, Auk, 1884, p. 275 (Entrerios).

Description.—Above pale brown; nape plumbeous; outer wing-coverts and scapularies with a few black spots; wings dark grey, with fine 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.

360. METRIOPELIA MELANOPTERA (Mol.).
(BLACK-WINGED DOVE.)

Metriopelia melanoptera, Burm. La-Plata Reise, ii. p. 496 (Cordilleras); Scl. et Salv. Nomencl. p. 132.

Description.—Above pale brown; wings and tail black; bend of wing white; wing-coverts like the back: beneath pale vinaceous; bill and feet black: whole length 8·0 inches, wing 5·0, tail 3·5. Female similar.

Hab. Andes of South America.

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.

361. METRIOPELIA AYMARA (Knip et Prév.).
(AYMARA DOVE.)

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.

362. COLUMBULA PICUI (Temm.).
(PICUI DOVE.)

Columbula picui, Burm. La-Plata Reise, ii. p. 496 (Mendoza, Paraná, Tucuman); Scl. et Salv. Nomencl. p. 133; iid. P. Z. S. 1868, p. 143 (Buenos Ayres); Durnford, Ibis, 1877, p. 193 (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.

363. CHAMÆPELIA TALPACOTI (Temm.).
(TALPACOTI DOVE.)

Chamæpelia talpacoti, Scl. et Salv. Nomencl. p. 133; White, P. Z. S. 1882, p. 626 (Salta).

Description.—Above deep reddish vinaceous; head plumbeous; wings 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.

364. ENGYPTILA CHALCAUCHENIA (Scl. et Salv.).
(SOLITARY PIGEON.)

Peristera frontalis, Burm. La-Plata Reise, ii. p. 497 (Paraná, Tucuman). Leptoptila megalura, White, P. Z. S. 1882, p. 626 (Salta) (?). Leptoptila chalcauchenia, Scl. et Salv. P. Z. S. 1869, p. 633; iid. Nomencl. p. 133; Salvin, Ibis, 1880, p. 363 (Salta); Barrows, Auk, 1884, p. 275 (Entrerios).

Description.—Above greyish brown; head and nape plumbeous; back of neck with the feathers edged with iridescent bronzy green; tail 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 similar.

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 Pigeons.


Order XII. GALLINÆ.

Fam. XLII. CRACIDÆ, or CURASSOWS.

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 forest-countries.

365. CRAX SCLATERI, G. R. Gray.
(SCLATER’S CURASSOW.)

Crax alector, Burm. La-Plata Reise, ii. p. 500. Crax sclateri, Gray, List of Gallinæ, p. 14 (1867); Scl. Trans. Zool. Soc. ix. p. 28, pls. xliv. & xlv.; Burm. P. Z. S. 1871, p. 702.

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 cross bars; crest white, barred with black: beneath, throat black, 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.

366. PENELOPE OBSCURA, Temm.
(DARK GUAN.)

Penelope obscura, Scl. et Salv. Nomencl. p. 136; iid. P. Z. S. 1870, p. 525; Barrows, Auk, 1884, p. 275 (Entrerios). Penelope boliviana, Burm. P. Z. S. 1871, p. 701 (Tucuman)? Penelope pileata, White, P. Z. S. 1882, p. 627 (Catamarca)?

Description.—Dark bronzy green; lower back and abdomen chocolate-brown; feathers of upper back, wing-coverts, and body beneath down to the middle of the belly margined with white; feathers of front part of head edged with silvery white: whole 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.

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.


9  Vol. iii. p. 72, no. 335.

367. PIPILE CUMANENSIS (Jacq.).
(WHITE-HEADED GUAN.)

Penelope pipile, Burm. La-Plata Reise, ii. p. 499 (Tucuman). Pipile cumanensis, Scl. et Salv. P. Z. S. 1870, p. 529; Burm. P. Z. S. 1871, p. 702 (Tucuman).

Description.—Bronzy black; whole top of the head white, with narrow black shaft-stripes; wing-coverts and breast-feathers edged with white; a large blotch on the wing white; naked cheeks and throat-caruncle blue: whole length 27·0 inches, wing 13·0, tail 11·0. Female similar.

Hab. South America from Venezuela to Northern Argentina.

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

368. ORTALIS CANICOLLIS, Wagl.
(HOARY-NECKED GUAN.)

Penelope canicollis, Burm. La-Plata Reise, ii, p. 499. Ortalida canicollis, Scl. et Salv. P. Z. S. 1870, p. 534; iid. Nomencl. p. 136; Burm. P. Z. S. 1871, p. 701. Ortalis canicollis, Salvin, Ibis, 1880, p. 303 (Tucuman). Ortalida guttata, White, P. Z. S. 1882, p. 627 (Salta)?

Description.—Above bronzy brown; top of head cinereous: beneath more ochraceous; throat and breast washed with bronzy; neck and 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.


Order XIV. GERANOMORPHÆ.

Fam. XLIII. RALLIDÆ, or RAILS.

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.

369. RALLUS MACULATUS, Bodd.
(SPOTTED RAIL.)
[Plate XIX.]

RALLUS MACULATUS.

Rallus maculatus, Scl. et Salv. Nomencl. p. 139; iid. P. Z. S. 1868, p. 444; Durnford, Ibis, 1878, p. 65 (Buenos Ayres); Barrows, Auk, 1884, p. 276 (Entrerios); Withington, Ibis, 1888, p. 471 (Lomas de Zamora).

Description.—Above blackish; back and wings dark olive-brown, spotted all over with white: beneath barred across with white and black; chin and crissum white; bill yellow, with a bright red spot at the base; feet pale brown: whole length 11·0 inches, wing 5·2, tail 2·0. Female similar.

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.”

370. RALLUS ANTARCTICUS, King.
(ANTARCTIC RAIL.)

Rallus antarcticus, Scl. et Salv. Nomencl. p. 139; iid. P. Z. S. 1868, p. 445; iid. Ex. Orn. t. lxxxii. p. 163; Barrows, Auk, 1884, p. 276 (Carhué); Withington, Ibis, 1888, p. 471 (Lomas de Zamora).

Description.—Above brown, striped with black; wing-coverts rufous; remiges blackish: beneath plumbeous; flanks and under wing-coverts black, barred across with white: whole length 8·0 inches, wing 3·7, tail 1·5. Female similar.

Hab. Chili, Argentine Republic, and Patagonia.

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.

371. RALLUS RHYTIRHYNCHUS, Vieill.
(BLACK RAIL.)

Aramides rhytirhynchus, Burm. La-Plata Reise, ii. p. 504 (Paraná). Rallus rythyrhynchus, Scl. et Salv. Nomencl. p. 139; iid. P. Z. S. 1868, p. 145 (Buenos Ayres) et p. 446; Hudson, P. Z. S. 1870, p. 104 (Buenos Ayres); Durnford, Ibis, 1878, p. 65 (Buenos Ayres); White, P. Z. S. 1883, p. 42 (Cordova); Barrows, Auk, 1884, p. 276 (Entrerios). Rallus nigricans, Durnford, Ibis, 1877, p. 193.

Description.—Above greenish brown; beneath plumbeous; bill incurved, greenish, with a blood-red basal spot; feet red: whole length 12·0 inches, wing 5·4, tail 2·8. Female similar.

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.

372. RALLUS NIGRICANS, Vieill.
(PLUMBEOUS RAIL.)

Aramides nigricans, Burm. La-Plata Reise, ii. p. 504. Rallus nigricans, Scl. et Salv. P. Z. S. 1868, p. 446; iid. Nomencl. p. 139.

Description.—Above olivaceous brown; front, side of the head, and body beneath plumbeous; throat whitish; lower belly, thighs, and tail blackish; bill straight, uniform dark greenish: whole length 10·0 inches, wing 5·3, tail 2·8. Female similar.

Hab. South Brazil, Paraguay, and Northern Argentina.

This Rail is said by Dr. Burmeister to occur near Buenos Ayres, but the bird taken for this species by Durnford (Ibis, 1877, p. 193; 1878, p. 66) appears to have been R. rhytirhynchus.

373. ARAMIDES YPECAHA (Vieill.).

“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 motions.

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.

Description.—Brownish olive, head reddish; wings, tail, and hind back darker: beneath white; sides of the head and of the neck and breast chestnut-red; flanks barred with white and black; crissum black in the middle, white on each side; bill olivaceous; feet yellowish: whole length 6·75 inches, wing 3·1, tail 1·9. Female similar.

Hab. S. Brazil, Paraguay, and N. Argentina.

This Crake is an inhabitant of Southern Brazil and Paraguay, but also occurs in the Northern Provinces of the Argentine Republic, where it was met with by Dr. Burmeister in Tucuman.

375. PORZANA SALINASI (Philippi).
(SPOT-WINGED CRAKE.)

Rallus salinasi, Philippi, Wiegm. Arch. 1857, pt. i. p. 262 (Chili); Burm. Ibis, 1888, p. 285. Porzana spiloptera, Durnford, Ibis, 1877, p. 194, pl. iii. (Buenos Ayres).

Description.—Above olive-brown with black markings; wings with white cross bands; front, sides of head, and body beneath plumbeous; flanks dark grey, with transverse bars of white; under tail-coverts barred with black and white; beak dark horn-colour; feet rather 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 Museum.

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.
