 several, when they took no notice of other individuals; and they avoided my horse in the pastures, after I had made use of him to approach and shoot them.

At the commencement of the love season, which is about the beginning of February, the gesticulation and parade of the males are extremely ludicrous. They first strut somewhat in the manner of the Turkey Cock, then open their wings, and, as they approach the female, lower their head, its wrinkled skin becoming loosened, so as entirely to cover the bill, and emit a puffing sound, which is by no means musical. When these actions have been repeated five or six times, and the conjugal compact sealed, the "happy pair" fly off, and remain together until their young come abroad. These birds form no nest, and consequently never breed on trees; the hollow of a prostrate log, or the excavation of a bank of earth, suffices for them. They never lay more than two eggs, which are deposited on the bare ground; they are about three inches in length, rather pointed at the smaller end, thick in the shell, with a pure white ground, marked towards the greater ends with large irregular dashes of black and dark brown. Twenty-one days are required for hatching them. The male and female sit by turns, and feed each other. The young are at first covered with a light cream-coloured down, and have an extremely uncouth appearance. They are fed by regurgitation, almost in the same manner as pigeons, and are abundantly supplied with food. When fledged, which is commonly about the beginning of June, they follow their parents through the woods. At this period, their head is covered with feathers to the very mandibles. The plumage of this part gradually disappears, and the skin becomes wrinkled; but they are not in full plumage till the second year. During the breeding season, they frequent the cities less, those remaining at that time being barren birds, of which there appear to be a good number. I believe that the individuals which are no longer capable of breeding, spend all their time in and about the cities, and roost on the roofs and chimneys. They go out, in company with the Turkey Buzzards, to the yards of the hospitals and asylums, to feed on the remains of the provisions cooked there, which are as regularly thrown out to them.

I have represented a pair of Carrion Crows or Black Vultures in full plumage, engaged with the head of our Common Deer, the Cervus virginianus.
