Young much more brown ; a wide Iroivniih black band on abdomen ; other under parts yellowish, with a few brownish lines 
and spots. Tail white, with a light brown band near tip. 
A large hawk, with legs densely feathered to the toes, and which cannot be easily confounded with any other American 
species. It is distinguished from the young of the black hawk, (.4. Sancii Johannis,) by its smaller size and fewer dark spots 
on the under parts. — Cassix. 
No. 8549, Shoalwatcr bay, October 31, 1854, (109.) Length, 21 ; extent, 52 inches. Iris, pale brown ; bill, slate colored 
and yellow ; feet, yellow. 
In October, 1854, I found a large number of the rough legged buzzard on a low jooint near 
the seacoast, covered Avith small pines, where they were sitting like owls, on the dead tree 
tops, occasionally darting down after a mouse, and alighting ti 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, 0. T. 
It seemed old and feeble, and, either from weakness or apathy, allowed nie 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.
