Species of this genus inhabit principally the northern parts of the wo -Id, and are 

 generally characterized by the prevalence of gray or cinereous, of various shades, in 

 their plumage.

 'ong; upper parts smoky or ashy brown, mottled and transversely barred with 

 ashy- white; under parts ashy-white, with numerous longitudinal stripes of dark 

 ashy-brown predominating on the breast, and with transverse stripes of the same on 

 the abdomen, legs, and under tail coverts ; quills brown, with about five wide, irregu- 

 lar bands of ashy-white ; tail brown, with five or six wide, irregular bands of ashy- 

 white, mottled with dark-bro wn ; feathers of the disc on the neck tipped with white ; 

 eye nearly encircled by a black spot; radiating feathers around the eye, with regular

This bird is an extremely rare winter visitor in New Eng- 

 land ; appearing only in the southern districts of these 

 States, in Massachusetts even, in very severe seasons. I 

 never saw one alive ; have, of course, never seen its nest, 

 and can add nothing at all to our knowledge of its habits. 

 It breeds in the most northern regions ; and, according to 

 Dr. Brewer, " nests in high trees." Its eggs I have never 

 seen. Audubon gives the following account of this spe- 

 cies : — 



" The comparatively small size of this bird's eyes renders it 

 probable that it hunts by day ; and the remarkable smallness of its 

 feet and claws induces me to think that it does not prey on large 

 animals. Dr. Richardson says, that ' it is by no means a rare bird 

 in the fur countries ; being an inhabitant of all the woody districtsf 

 lying between the Lake Superior and latitudes 67° or 68°, and 

 between Hudson's Bay and the Pacific. It is common on the 

 borders of Great Bear Lake ; and there, and in the higher parallels 

 of latitude, it must pursue its prey, during the summer months, by 

 daylight. It keeps, however, within the woods, and does not fre- 

 quent the barren grounds, like the Snowy Owl; nor is it so often met
