upper parts dark ashy bluish or slate color, with the shafts of the feathers black, and frequently with the feathers narrowly 
edged with black, presenting a squamate or scale-like appearance. A conspicuous stripe over the eye, and an obscure and 
partially concealed occipital and nuchal band, white. Entire under parts mottled with white and light ashy brown. Every 
feather with a longitudinal line of dark brown on its shaft, and with numerous irregular and imperfect transverse lines or 
narrow stripes of light ashy brown, more distinct and regular on the abdomen and tibie. Quills brown, with bands of a deeper 
hade of the same color, and of ashy white on their inner webs. Tail same color as other upper parts; under surface very pale,

Total length, female, 22 to 24 inches, wing about 14, tail 104 to 11 inches. vithe, about 20 inches, wing 124, tail 9! inches, 
Hab. North America, chiefly in the northwestern portions. 
All the specimens of this fine species in the collections of the expeditions are from Oregon 
and Washington Territory, and are of both adults and young birds. It is apparently more 
abundant in northwestern America than it is known to be in any other portion of the United 
States. 
The adult of this species is well known, and is represented in all the plates cited above. It 
is one of the most strongly marked and easily recognized of American hawks. 
Though confounded with the European goshawk (Astur palumbarius) by Audubon, the 
present species is strongly marked, and easily distinguished. The transverse bands:on the
