RAPTORES : Birds of Prey 



COOPER HAWK 



(333. Accipiter cooperi) 14-20 in. 



Male: Bluish gray above; crown nearly black; under parts 

 finely barred white and rusty; tail long, rounded, with several 

 dusky bands on light ground. 14-16 in. 



Female: Less bluish above; sides of head and neck more rusty. 

 17-20 in. 



Immature: Dark brown above; white and dusky-streaked 

 below. 



Females usually identifiable by size, while males are hardly 

 larger than a female Sharp-shin. 



GOSHAWK 



(334. Astur atricapillus atricapillus) 22-25 in. 



Sexes alike. Whole upper parts clear blue-gray, with black 

 crown; white below, finely and irregularly barred with slaty; a 

 black stripe behind eye and a white one above eye, to nape. 



Immatures: Dusky or grayish above, buffy-edged; below, pale 

 buffy, feathers with broad black central streaks. 



Long tail and short wings, with large size, and timber-haunt- 

 ing habit, easily identify this bird. Highly destructive to Grouse 

 and Quail. 



WESTERN GOSHAWK 



(334a. Astur atricapillus striatulus) 



Said to differ from preceding in darker upper parts and 

 broader, darker striping below. (Recognized in A.O.U. Check- 

 List but now generally believed to be the immature of the 

 Goshawk, and as such to have no standing as a different form.)
