THE TURKEY BUZZARD.

PLATE CLI. Male and Young.

Having already, when speaking of the Black Vulture, described the habits of the Turkey Buzzard, I shall here merely add a few observations necessary to complete its history.

This species is far from being known throughout the United States, for it has never been seen farther eastward than the confines of New Jersey. None, I believe, have been observed in New York; and on asking about it in Massachusetts and Maine, I found that, excepting those persons acquainted with our birds generally, none knew it. On my late northern journeys I nowhere saw it. A very few remain and spend the winter in New Jersey and Pennsylvania, where I have seen them only during summer, and where they breed. As we proceed farther south, they become more and more abundant. They are equally attached to maritime districts, and the vicinity of the sea-shore, where they find abundance of food.

The flight of the Turkey Buzzard is graceful compared with that of the Black Vulture. It sails admirably either high or low, with its wings spread beyond the horizontal position, and their tips bent upward by the weight of the body. After rising from the ground, which it does at a single spring, it beats its wings only a very few times, to enable it to proceed in its usual way of sailing. Like the Black Vultures, they rise high in the air, and perform large circles, in company with those birds, the Fork-tailed Hawk, Mississippi Kite, and the two species of Crow. The Hawks, however, generally teaze them, and force them off toward the ground.

They are gregarious, feed on all sorts of food, and suck the eggs and devour the young of many species of Heron and other birds. In the Floridas, I have, when shooting, been followed by some of them, to watch the spot where I might deposit my game, which, if not carefully covered, they would devour. They also eat birds of their own species, when they find them dead. They are more elegant in form than the Black Vultures, and walk well on the ground or the roofs of houses. They are daily seen in the streets of the southern cities, along with their relatives, and often roost with them on the same trees. They breed on the ground, or at the bottom of hollow trees and prostrate trunks, and lay only two eggs. These are large, of a light cream-colour, splashed toward the great end with large irregular markings of black and brown. The young somewhat resemble those of the Black Vulture, and take a long time before they can fly. Both species drink water freely, and in doing this immerse their bill to the base, and take a long draught at a time. They both breed at the same period, or nearly so, and raise only one brood in the season.

I have found birds of this species apparently very old, with the upper parts of their mandibles, and the wrinkled skin around their eyes, so diseased as to render them scarcely able to feed amongst others, all of which seldom failed to take advantage of their infirmities. I have represented the adult male in full plumage, along with a young bird, procured in the autumn of its first year. The average weight of a full grown bird is 6½ lb., about 1 lb. less than that of the Carrion Crow.

Adult Male. Plate CLI. Fig. 1.

Bill nearly as long as the head, strong, straight at the base, compressed; the upper mandible covered beyond the middle by the cere, its dorsal outline nearly straight, being slightly undulated, its tip large, curved, and pointed, and of a boney hardness; the edge with a slight undulation; lower mandible with the end rounded, and having a broad groove. Nostrils medial, approximate, oblong, pervious, of very large size, and forming an open space, into which posteriorly open the two nasal tubes, which are furnished each with a valve. Head elongated, small, neck rather long, body robust. Feet strong; tarsus roundish, covered with small hexagonal scales; toes scutellate above, the middle one much longer, the two lateral nearly equal, and united to the middle one at the base by a web, the hind-toe small. Claws arched, strong, acute, that of the hind-toe smallest.

Plumage rather compact, with ordinary lustre, the back somewhat metallic. The head and upper part of the neck are destitute of feathers, having a red wrinkled skin, sparsely covered with short black hair, and downy behind. Feathers of the neck full and rounded, concealing the naked crop. Wings ample, long; the first quill rather short, the third and fourth longest. Tail longish, rounded, of twelve broad straight feathers.

Bill at the tip yellowish-white; the cere and the naked part of the head of a tint approaching to blood-red. Iris dark brown. Feet flesh-coloured, tinged with yellow; claws black. The general colour of the plumage is blackish-brown, deepest on the neck and under parts, the wing-coverts broadly margined with brown; the back glossed with brown and greenish tints; the tail purplish-black; the under parts of a sooty brown, on the breast glossed with green.

Length 32 inches, extent of wings 6 feet 4 inches; bill 2½ along the ridge, 2 2/12 along the gap; tarsus 2½, middle-toe 3½.

Young fully fledged. Plate CLI. Fig. 2.

The bill is, of course, shorter and more slender, its horny tip pale blue, black on the back; the skin of the head is flesh-coloured, the iris yellowish, the feet flesh-coloured. The plumage is nearly of the same colour as in the adult.
