292 BLA CK HA WK. 



coloured hawk of Pennant, and St John's falcon of the same 

 author (Arct. Zool., No. 93 and 94), are doubtless varieties 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.

This is probably a younger bird of the preceding species, 

 being, though a male, somewhat less than its companion. 

 Both were killed in the same meadow, at the same place and 

 time. In form, features, and habitudes, it exactly agreed with 

 the former. 



This bird measures twenty inches in length, and in extent, 

 four feet ; the eyes, bill, cere, toes, and claws, were as in the 

 preceding ; head above, white, streaked with black and light 

 brown; along the eyebrows, a black line; cheeks, streaked like 

 the head ; neck, streaked with black and reddish brown, on 

 a pale yellowish white ground ; whole upper parts, brown 

 black, dashed with brownish white and pale ferruginous ; 

 tail, white for half its length, ending in brown, marked with 

 one or two bars of dusky and a larger bar of black, and tipt 

 with dull white ; wings as in the preceding, their lining varie- 

 gated with black, white, and ferruginous ; throat and breast, 

 brownish yellow, dashed with black ; belly, beautifully varie- 

 gated with spots of white, black, and pale ferruginous ; 

 femorals and feathered legs, the same, but rather darker; 

 vent, plain brownish white.
