Wilson, Alexander, 1766-1813. / American ornithology; or The natural history of the birds of the United States
Species 14. Falco niger. Black hawk, pp. -104
104 BLACK HAWK. dashed with dirty white; nape of the neck pure white under the surface;,,front white; whole lower parts black, with slight tinges of brown, and a few circular touches of the same on the femorals; legs feathered to the toes, and black, touched with brownish; the wings reach rather beyond the tip of the tail; the five first primaries are white on their inner vanes; tail rounded at the end, deep black, crossed with five narrow bands of pure white, and broadly tipt with dull white; vent black, spotted with white; inside vanes of the primaries snowy; claws black, strong and sharp; toes remarkably short. I strongly suspect this bird to be of the very same species with the next, though both were found to be males. Although differing greatly in plumage, yet in all their characteristic fea- tures they strikingly resemble each other. The Chocolate- coloured Falcon of Pennant, and St. John's Falcon of the same author, (Arct. Zool. No. 93 and 94,) are doubtless varie- ties of this; and very probably his Rough-legged Falcon also. His figures, however, are bad, and ill calculated to exhibit the true form and appearance of the bird. This species is a native of North America alone. We have no account of its ever having been seen in any part of Europe; nor have we any account of its place, or manner, of breeding.
