ZOOLOGY. 149 



Young much more bro\vn ; a wide Irmi'nUk black band on abdomen ; other under parts yellowish, with a few brownish Hues 

 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 sm.aller size and fewer dark spots 

 on the under parts. — Cassix. 



No. 8549, Shoalwater hay, October 31, 1S54, (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 point near 

 the seacoast, covered -with small pines, where they were sitting like owls, on the 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 Port Dalles, 0. 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.
