42 Wyoming Birds. 



332. Accipiter velox: Sharp-shinned Hawk. 



Rather an uncommon summer resident over the entire state. 



333. Accipiter cooperi: Cooper's Hawk. 



Uncommon summer resident in the northern half of the 

 state. There are no records for the southern portion. 



334. Astur atricapillus atricapillus: Goshawk. 



Knight gave but one record for this bird. Lockwood re- 

 ports it and Walker conditionally refers one record to this 

 species. 



334a. Astur atricapillus striatulus: Western Goshawk. 



Very uncommon in the state. The only records are by 

 Metz, Lockwood and Buck. 



337a. Buteo borealis krideri: Krider's Hawk. 



Knight recorded it as an uncommon summer resident. Pea- 

 body is the only recent observer who reports it. Probably 

 many of the records which are accredited to calurus should 

 belong to this form. 



337b. Buteo borealis calurus: Western Red-tail. 



Rather uncommon summer resident over most of the state. 



342. Buteo swainsoni: Swainson's Hawk. 



An abundant hawk over almost the entire state. 



347a. Archibuteo lagopus sancti-johannis: Rough-legged Hawk. 

 Our only recent records are from Peabody and Lockwood, 

 who merely record this bird. Knight reported it as a 

 rather common migrant. 



348. Archibuteo ferrugineus: Ferruginous Rough-leg. 



Apparently a fairly common resident over most of the 

 state. 



349. Aquila chrysaetos: Golden Eagle. 



The most common eagle of the state, found throughout al- 

 most all the mountain region. 



352. Haliaeetus leucocephalus leucocephalus: Bald Eagle. 



Rather rare resident over the entire state. Apparently most 

 common in the vicinity of Yellowstone National Park.
