FALCONID.E. 35 



black bars, several on each feather. There are twelve black bars on the middle tail feathers, 

 and nine on the outer ones ; and the outer webs of the latter are nearly white. The flag 

 feathers are coloured externally, as in the male ; but the white marks on their inner webs are 

 deeply tinged with brown. The throat, posterior part of the belly, and under tail coverts, are 

 white, as in the male ; the breast, fore part of the belly, and the flanks, are soiled-white, 

 marked longitudinally with oblong yellowish-brown spots. On the linings of the wings the 

 yellowish-brown is the ground colour, and is spotted with white. The under surfaces of 

 the quill and tail feathers are slightly tinged with buff-colour, and are crossed by brownish- 

 grey bars. 



The total length of the specimen is one foot ; that of the tarsus one inch and a half: the 

 other dimensions correspond with those of the male, the female of this species scarcely 

 exceeding the other sex in size. 



A young male had nearly the plumage of the female, differing only in the black 

 bars on the wings being more distinct, those on the tail narrower, and in the 

 upper tail coverts being brownish-red, without spots. 



In a young female the tips of the flag feathers were margined with white and 

 the whole abdomen was marked with yellowish-brown spots.

This fierce little Falcon makes it appearance on the coast of Hudson's Bay in 

 May, and, having reared its young, retires to a warmer climate in September. It 

 is not uncommon about York Factory, in latitude 57°, and probably wanders 

 much farther north. Early in the spring of 1825, I observed a small Hawk 

 on the north shore of Great Bear Lake, in latitude 66°, which, if not of this 

 species, belongs to a still smaller one, that is hitherto undescribed as a North 

 American bird. It had taken possession of a tree, and was so unwilling to go away, 

 that, when I threw stones at it, it merely made two or three circles round my head, 

 with much clamour, and returned to its former perch. The want of a gun at the 

 time prevented me from procuring the specimen.
