COOPER'S BUZZARD. 



Buteo cooperi. 



The type specimen of this hawk was taken near Mountain View, in 

 the Santa Clara Valley, California, by Br, Cooper, in No^•ember, 1855, 

 and remains unique to this day. Absolutely nothing is known of its 

 life history, and hence no positive information can be given of its tood 

 habits. Its size and general make-up prove it to belong to the class of 

 heavy moving hawks, and it is x>robable that its food and habits con- 

 form in general to theirs. 



BROAD-WINGED HAWK. 



^''Buteo latissimus. 

 [Plate 10— Adult.] 



The Broad-winged Hawk inhabits eastern North America from New 

 Brunswick and the Saskatchewan River, ranging south through the 

 United States, east of the Great Plains, to Middle America, West Indies, 

 and northern South America. It migrates in September and October 

 from the region north of latitude 40° and winters from this point south- 

 ward. In March and early April it again passes north, often in consid- 

 erable tlocks. It breeds throughout the eastern United States as far 

 north as the limit of its range. 



The food of this Hawk consistsi^rincipally of insects, small mammals, 

 reptiles, and batrachians, and occasionally of young or disabled birds. 

 A specimen secured by the writer in May, just after a shower, was 

 gorged with large earth worms. In the spring, when toads frequent
