38 CALIFORNIA ACADEMY OF SCIENCES. 



Camp Harney. Capt. Bendire. An irregular winter 

 visitor; common at some seasons and entirely wanting 

 in others. 



Ridgway. This common species was observed nearly 

 everywhere in the vicinity of the fertile valleys. It ap-

33. Archibuteo ferrugineus (Licht.) FERRUGINOUS
