BLACK HAWK. 
dashed with dirty white; nape of the neck pure white under 
the surface; ivont 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.
