The Wild Pigeon has been successfully kept in aviaries, and has occasionally bred in confinement.
Wilson’s account of the habits of these Pigeons is substantially corroborative of that of Audubon. He witnessed their migrations in vast numbers, in various parts of the country,—in Western New York, in Pennsylvania, in various parts of Virginia, where he beheld their immense flocks with amazement, but where they were mere straggling parties compared with the congregated millions he saw in Ohio, Indiana, and Kentucky. He also noted their habit of frequenting the same roosting-place night after night, even when they were compelled to fly sixty or eighty miles each day to their feeding-places. His account of their roosting-places is similar to that of Audubon, corroborating the accumulation of the dung covering the surface of the ground and destroying all the grass and underbrush, the breaking down of large limbs, and even of small trees, by the weight of the birds clustering one above another, and the trees themselves at last killed as completely as if girdled by an axe.
One of the breeding-places visited by Wilson, not far from Shelbyville, Ky., stretched through the forest in nearly a north and south direction. This was several miles in breadth, and upwards of forty miles in extent. In this immense tract nearly every tree was furnished with nests wherever there were branches to accommodate them. He was informed by those who had sought to plunder the nests of the squabs, that the noise in the woods was so great as to terrify their horses, and that it was difficult for one person to hear another speak. The ground was strewed with broken limbs, eggs, and young Pigeons. Hawks were sailing about in great numbers, while from twenty feet upwards to the tops of the trees there was a perpetual tumult of crowding and fluttering multitudes of Pigeons, their wings resounding like thunder, and mingled with the frequent crash of falling trees. In one instance he counted ninety nests in a single tree.
When on his way from Shelbyville to Frankfort, Wilson witnessed an immense flight of these birds, and was astonished at their appearance. They were flying with great steadiness and rapidity in several strata deep and very close together. From right to left, as far as the eye could reach, this vast procession extended its immense breadth, seeming everywhere equally crowded. For more than an hour by the watch he stood and observed this prodigious procession, which, instead of diminishing, seemed rather to increase both in numbers and rapidity. Three hours later, as he was entering Frankfort, the living torrent above his head was as numerous and extended as when first observed. Wilson computed the number of Pigeons in this flight at over two thousand two hundred millions.
The most southern point at which this Pigeon is known to breed, as given by Wilson, was in the Choctaw country, in Mississippi, in latitude 32°.
Mr. Ridgway obtained a single specimen of this species in the West Humboldt Mountains, in September, 1867. It was a young bird, and had been feeding on the berries of a species of Cornus.
The eggs of the Wild Pigeon vary considerably in length, and also somewhat in breadth. They average about 1.45 inches in length and 1.05 in breadth. They are white in color, have an oval shape, and are equally rounded at both ends.
Subfamily ZENAIDINÆ
Char. Tarsi stout, lengthened; always longer than the lateral toes, and entirely without feathers; the tibial joint usually denuded. Tarsus sometimes with hexagonal scales anteriorly. Tail-feathers sometimes fourteen.
This subfamily is readily distinguished from the preceding by the longer and more denuded tarsi, the feet being much better fitted for a terrestrial life. The following sections belong to it:—
Zenaideæ. Size moderate. Wings lengthened, acute, the primaries much longer than the secondaries. Tarsus scutellate anteriorly. A blackish spot beneath the auriculars; tail-feathers tipped with white, and with a blackish subterminal bar. Sides of the neck with a metallic gloss.
Bill lengthened, much depressed. A white patch on the wing; no black spots on the scapulars; plumage ashy, lighter beneath. Tail of twelve feathers, rounded … Melopelia.
Bill smaller, more compressed. No white patch on the wing; scapulars with black spots. Above olivaceous, beneath vinaceous.
Tail of twelve feathers rounded … Zenaida.
Tail of fourteen feathers, graduated or cuneate … Zenaidura.
Chamæpelieæ. Size very small. Wings rounded, the primaries scarcely longer than the tertials. Tarsus scutellate anteriorly. No blackish spot beneath the auriculars; no metallic gloss on sides of the neck.
Tail of twelve feathers, lengthened (much longer than wings), doubly rounded, the lateral feathers much shorter; the three outer pairs with white terminally … Scardafella.
Tail of twelve feathers, short (much less than wings), simply rounded, the lateral feathers only slightly shorter; outer feathers without white terminally, or with only a slight edging. Wing-coverts with oblique black spots, and body without transverse blackish bars.
Outside of the tarsus with a narrow feathered strip; lining of the wing blackish … Talpacota.
Outside of the tarsus without a feathered strip; lining of the wing wholly rufous … Chamæpelia.
Starnœnadeæ. Size moderate (generally a little larger than Zenaida); form robust, or quail-like. Legs very stout; tarsi decidedly longer than the middle toe, variously scaled anteriorly. Wings short, very broad, and much rounded, but the primaries decidedly longer than the secondaries.
Legs very stout; tarsi covered with hexagonal scales; crown blue; a black gular patch, bordered below by white … Starnœnas.
Legs moderate; tarsi covered anteriorly with transverse scutellæ. Crown never blue, and throat without black or white markings … Geotrygon.
The genera characterized above are all more or less nearly related to others belonging to South America, and many of these apparently form connecting links between the several North American ones. Thus, “Columbina” picui, Gray (of Chili), and C. strepitans (of Paraguay), are almost exactly intermediate between Scardafella and Chamæpelia, both in form and colors. “Leptoptila” is in reality scarcely more than a very large Chamæpelia with an approach to Zenaida in more lengthened primaries, and to Geotrygon in the lengthened tarsus.
“Peristera” cinerea is again a slightly enlarged reproduction of Chamæpelia, with the same pattern of coloration, but without rufous on the inside of the wing.
Starnœnas and Geotrygon are nearly connected by the G. chiriquensis, which agrees with the genus to which it is referred in the scutellate tarsi, and with Starnœnas in the peculiar structure of the feathers of the neck, which have, as in that “genus,” a stiff, compact structure, and rather raylike arrangement.
Genus MELOPELIA, Bonap
Melopelia, Bonap. Consp. II, Dec. 1854, 81. (Type, Columba leucoptera, L.)
Gen. Char. Similar to Zenaida; the orbital region and lore more naked; the bill longer; the middle toe longer; the hinder shorter. Tarsal scutellæ in a single series anteriorly. First quill nearly as long as the second and third. A large white patch on wing-coverts, lower parts light ashy.
This genus, like nearly all the North American ones, is represented by but a single species in the United States.

Melopelia leucoptera, Bonap.
Hab. Southern border of United States, from Texas to Arizona and Lower California; Mexico, south to Costa Rica, Cuba and Jamaica, Oaxaca, highlands (Scl. 1858, 305); Cordova (1856, 309); Jamaica (Gosse, B. J. 304); Honduras (Taylor, Ibis, II, 227); City of Mexico (Scl. P. Z. S. 1864, 178); Southeastern Texas, breeding (Dresser, Ibis, 1866, 24); Cuba (Gundl. Rep. I, 1866, 301); Fort Whipple, Arizona (Coues, P. A. N. S. 1866, 93); Costa Rica (Lawr. IX, 139); Yucatan (Lawr. IX, 207).
However remarkable and exceptional the distribution of this species may appear in occurring in Cuba and Jamaica and in Mexico, from the Atlantic coast to Cape St. Lucas, and north to Santa Fé, New Mexico, we have yet been unable to find any tangible differences in specimens from these extreme localities. The Jamaica bird has rather a more decided wash of brown on the neck and forehead, the toes apparently shorter; but as specimens from the same locality vary in this respect, it is probable that in a large series such differences will disappear in the average.

Melopelia leucoptera.
Habits. This species is found on the Lower Rio Grande, in Arizona, and, according to Dr. Cooper, in California. It also occurs in Mexico, and was taken in Tamaulipas by Lieutenant Couch, March, 1858. It has also been met with in several of the West India Islands and in Central America.
This species is abundant in Jamaica, where, according to Mr. March, it is more a lowland than a mountain Dove. They are said to be gregarious, usually keeping in flocks of from ten to twenty, but in January and in February, in the Guinea-corn season, and at other times when the Cerei are in fruit, they congregate in large flocks, often of several hundreds. Their food is principally grain and seeds, but they are equally fond of the ripe fruit of the different species of Cereus abounding on the savannas and salines during the summer. Inland, the White-wings, in the same manner as the Baldpate, breed in solitary pairs; but in the mangrove swamps, and in the islands along the coast, they breed in company, many in the same tree. The nest is a frail platform of sticks, with a slight hollow lined with leaves and bark, and sometimes a few feathers. The eggs are two, of an oblong-oval shape, glarish-white in color, measuring 1.31 inches in length by .94 of an inch in breadth. Mr. March adds that the White-wing is often kept in confinement, where it occasionally breeds. It is at first quite wild, fluttering in alarm at the approach of any person, but afterwards becomes quite docile if attended with care. It has been known to cross and mate with the Turtur risorius, a bird which has been introduced into Jamaica. Mr. March had, at the time his paper appeared, a male White-wing mated with a female Ringdove.
This species was found at Omoa, Honduras, by Mr. Leyland, and by Mr. Salvin about Dueñas, Guatemala, where it was one of the common Doves. It was found on the ground, in the open savannas.
Mr. G. C. Taylor (Ibis, 1860) found this bird abundant in Central America, especially on the Pacific coast and in the environs of Comayagua. He adds that he found this species most plentiful in the vicinity of houses and cornfields, while the Z. carolinensis seem to prefer the woods and open plains. Both were easily shot, and were found to be excellent eating.
Mr. Dresser found this species very common near Matamoras and Brownsville, and as far into the interior of Texas as Sal Colorado, after which it becomes rare, and he never saw any farther east or north than the Rio Nueces. It is not uncommon at Eagle Pass, where he saw many in cages in the huts of the Mexicans. Their stomachs were found to contain maize and caterpillars.
Mr. Xantus, in his notes upon the birds of Cape St. Lucas, mentions finding several of the nests and eggs of this Dove. All the nests mentioned contained two eggs. One was in the fork of a leafless tree, about ten feet from the ground; another was about six feet high and placed on a small dwarf-oak; and a third, found May 20, was in a thorn-bush, about ten feet from the ground. In one instance a single egg, already incubated, was found on the top of a large cactus trunk, but without any indication of a nest.
The eggs of this species are oval in shape, white, of equal size at either end, and measure 1.35 inches by .92.
Genus ZENAIDA, Bonap
Zenaida, Bonaparte, Geog. & Comp. List, 1838. (Type, Columba zenaida, Bp.)
Gen. Char. Bill black; the culmen about two fifths the rest of the head. Tarsi a little shorter than the middle toe and claw, but considerably longer than the lateral toes. Tarsus with broad scutellæ anteriorly, those on the lower half bifid, making two hexagonal series. Inner lateral toe a little the longer. Hind toe and claw as long as the inner lateral without claw. Wings lengthened; second and third quills longest. Tail short, about two fifths the wings, rounded or a little graduated. Orbits feathered, especially anterior to the eye; the lids bare.
But one species of this genus belongs to our fauna, and this is probably but an occasional visitor.

Zenaida amabilis.
Hab. Florida Keys. Chiefly on or near Indian Key and the West Indies. Santa Cruz (Newton, Ibis, I, 253, eggs); Cuba (Cab. J. IV, III; Gundl. Rep. I, 1866, 301); Bahamas (Bryant, Pr. B. VII, 1859); Jamaica (Gosse, B. J. 317); Sombrero (Lawr. VIII, 99); Porto Rico (Bryant, B. P. 1866).
Among many specimens of this species before us is one from Mr. Audubon’s collection, probably procured in Florida. It must be much rarer now than formerly on the keys, as several collections of birds made on Indian Key do not include any specimens.
The Z. hypoleuca, Gray,106 of South America, is very similar, but lacks any trace of the broad white bar at the end of the secondaries. There is more white on the tail, the feathers of which are narrower at the ends; besides, the colors generally are lighter, the crissum being creamy-white.
Habits. The Zenaida Dove was found by Mr. Audubon to be a transient visitor of the keys of East Florida, where, according to his observations, they made their first appearance among the islands around Indian Key about the 15th of April. There they continued to increase in numbers until October, when they all returned to the West India Islands, whence they came, and where they are most numerous. The males were observed to reach the keys in which they passed the summer to breed before the females, and were heard cooing, as if in search of their mates, at least a week before the arrival of the latter. They begin to lay their eggs about the first of May. When they leave, in their autumnal migrations, they depart in small groups by families.
These birds are said by Mr. Audubon to be Ground Doves in habit. Their flight resembles that of the so-called Ground Dove, and is seldom higher than the tops of the mangroves, and never to any considerable distance except during their migrations. Though they alight on trees with ease, and can walk well among their branches, they spend the greater portion of their time on the ground, and walk well there, walking or running in search of food with lightness and celerity, and invariably roost on the ground.
Their flight is similar to that of the Carolina Dove in the firm movements of the wings, though they do not produce the same whistling sounds. In flying over the water they keep near its surface; and when started from the ground they only fly to a short distance, and realight in the grass or a thicket. They are extremely gentle, so much so that Mr. Audubon has occasionally approached so near as to almost touch them with his gun as they stood gazing at him, apparently devoid of all fear.
They breed in the few keys that are covered with grass and low shrubs. They always place their nest on the ground, often with so little concealment that it may be easily discovered by any one searching for it. Occasionally it is placed between tufts of grass, the tops of which bend over and conceal it. A small hole is scooped in the sand in which a slight nest, composed of matted blades of dry grasses, is placed, circular in form, and embedded in an outer collection of dry leaves and twigs. The whole fabric is said to be more compact than the nest of any other Pigeon. The eggs, always two, are described as pure white and translucent.
When sitting on her eggs or on her young, the female rarely moved from them except when an attempt was made to catch her, which she always evaded with great dexterity, gliding with great quickness to a short distance, and watching the movements of the intruder with drooping wings and an air of deep sorrow, her whole frame trembling as if with intense cold.
Mr. Audubon took alive two of the young birds, which he fed from his mouth with Indian-corn meal. This they ate with avidity, until placed under the care of a common tame Pigeon, that at once fostered them. They lived, and were taken to Dr. Bachman in Charleston.
Their notes are said to closely resemble the cooing of the Carolina Dove, but are somewhat more soft and tender. During midday, when the heat in the central parts of the keys is intense, these birds are silent.
Their flesh was found to be excellent, and they were generally very fat. They fed on grass seeds, on the leaves of certain aromatic plants, and on various kinds of berries,—among others, one highly poisonous to man,—and mingle with their food particles of shells and gravel. They have two broods in a season.
According to Mr. Audubon, their eggs measure 1.25 inches in length by .87 of an inch in breadth, and are abruptly pointed at one end. He states that they propagated readily in the aviary of the Earl of Derby, some being let loose in the hope of introducing them into England.
This species, known in Jamaica as the Pea Dove, is not, according to March, gregarious, and, although terrestrial in habits, is often seen and heard on trees, and also roosts there. It nests indiscriminately on the ground or in trees, making a slight platform of sticks and twigs, loosely put together. The eggs are two, oval or roundish-oval in shape, and white. They measure from 1.20 to 1.32 inches in length by an inch in breadth. It is a favorite cage-bird, and though apparently very timid and restless, becomes very tame and docile, and will take grain from the hand or lips of its feeder.
In Santa Cruz it is known as the Mountain Dove, and was there found very common by Mr. Newton. It afforded excellent sport and was very good eating. It was not only numerous on the hills, but was likewise plentiful in all parts of the island sufficiently overgrown with brush. Mr. Newton did not find it so terrestrial in its habits as it is stated to be by some writers. Its flight is said to be remarkably rapid. It breeds from April to the end of July, and is said to build the ordinary Pigeon’s nest,—a mere platform of twigs in a bush or tree at any height from a few feet to twenty. It lays two eggs, which, in Santa Cruz, were found by Mr. Newton to be perfectly white, and not of a drab hue, as stated by Mr. Gosse. The young birds are often taken from the nest and brought up without much difficulty. The cooing of this Dove is stated to much resemble the noise made by sounding a conch-shell.
The eggs of the Zenaida Dove are more rounded in their shape than those of most of our Pigeons, are white, equally obtuse at each end, and measure 1.30 inches in length by .90 in breadth.
