80 FALCO NIGER. 
spotted with white; inside vanes of the v, 
snowy ; claws, black, strong and shaq) ; toes, rewa 
ab^ short. 
I stron|rly suspect this bird to he of the very 
species with the next, thou;?!! both were found to 
males. Althoun-h differing; greatly in plumage, y®*-,, 
all their characteristic features they .strikingly 
hie each other. The chocolate coloured hau'k , 
Pennant, and St John’s falcon, of the same authOjJ|j 
are doubtless varieties of this ; and, very probably> ^ 
rough-legged falcon also. His ligure.s, however, ‘j 
bad, and ill calculated to exhibit the true form 
appearance of the bird. 
This species is a native of North America alone- 
have no account of its ever having been seen 
part of Europe ; nor have we any account of its 
or manner of breeding.

WILSON, PLATE LIII. PIG. II. TOUNG BIHD. 
This is probably a younger bird of the preced'!^ 
species, being, though a male, somewhat less thaO ^ 
companion. Both were killed in the same meado''’|^j, j 
the same place and time. In form, features, and a® I 
tudes, it exactly agreed with the former. , jo 
This bird measures twenty inches in length, a® 
extent four feet ; the cye.s, bill, cere, toes, and rla^^j 
were as in the preceding j head above, white, 
with black and light brown ; along the eyebrows ® ",,itli 
line ; cheeks, streaked like the head ; neck, streaked 
black and reddish brown, on a pale yellowish 
ground ; whole upper parts brown black, dashed 
brownish white and pale ferruginous ; tail, white |
