Accipiter velox: Sharp-shinned Hawk. 
Rather an uncommon summer resident over the entire state. 
Accipiter cooperi: ‘Cooper’s Hawk. 
Uncommon summer resident in the northern half of the 
state. There are no records for the southern portion. 
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. 
Astur atricapillus striatulus: Western Goshawk. 
Very uncommon in the state. The only records are by 
Metz, Lockwood and Buck. 
Buteo borealis krideri: Krider's Hawk. 
Knight recorded it as an uncommon summer residettt. Pea- 
body is the only recent observer who reports it. Probably 
many of the records which are accredited to ca/urus should 
belong to this form.

Rather uncommon summer resident over most of the state. 
Buteo swainsoni: Swainson’s Hawk. 
An abundant hawk over almost the entire state.

Our only recent records are from Peabody and Lockwood, 
who merely record this bird. Knight reported it as a 
rather common migrant. 
Archibuteo ferrugineus: Ferruginous Rough-leg. 
Apparently a fairly common resident over most of the 
state. 
Aquila chrysaetos: Golden Eagle. 
lhe most common eagle of the state, found throughout al- 
most all the mountain region. 
Haliaeetus leucocephalus leucocephalus: Bald Eagle. 
Rather rare resident over the entire state. Apparently most 
common. in the vicinity of Yellowstone National Park.
