Part 88

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.

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, BONAP.

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, 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.
