TouDg much more brown ; a wide hrownish Hack band on abdomen ; other under parts ydlowish, with a few brownish linen 

 and spots. Tail white, with a light brown band near tip. 



A large hawk, with legs densely feathered to the toes, and which cannot bo easily confounded with any other American 

 species. It is distinguished from the young of the black hawk (.-1. Sandi Johannis) by its smaller size and fewer dark spots 

 on the under parts. — Cassin.

 and yellow ; feet, yellow. 



In October, 1854, I found a large number of the rough-legged buzzard on a low point near 

 the sea-coast, covered with small pines, where they were sitting like'owls on tlie dead tree tops, 

 occasionally darting down after a mouse, and alighting a short distance off. " Sometimes they 

 called to each other with a loud scream, but usually sat for hours motionless and silent. They 

 varied considerably in the amount and distribution of the white feathers, but the specimen shot 

 seemed to be one of the most perfect. One only was of a general dark chocolate color. Some 

 remained all winter, and I think a few build near the mouth of the Columbia, where I saw 

 young birds in July, 1855. — C.

I shot an adult specimen (female) in December, 1854, in the vicinity of Fort Dalles, O. T. 

 It seemed old and feeble, and, either from weakness or apathy, allowed me to approach very 

 closely to its resting place. Its plumage was worn, ragged looking, and appeared as if it had 

 not been changed at the previous moulting season. The tail only of this bird I preserved, as 

 I had a press of material on hand, and much other business to attend to. On showing it to 

 Mr. John Cassin, he pronounced it to belong to this species. — S.
