Turkey Vulture (Cathartes aura) - Turkey vultures were observed on three occasions, 

 twice in the badlands type (15, 18 May 1980) and once in the sage-grassland 

 type (5 May 1980). All three observations occurred on areas immediately adjacent 

 to the Yellowstone River. No evidence of breeding was found. Skaar (1980) 

 lists circumstantial evidence of breeding by this species in the latilong which 

 Includes the study area. Historically, this species was considered rare. 

 Cameron (1907) states that the only time they were numerous was in 1883 after 

 the slaughter of the northern bison (Bison bison) herd and after which they 

 declined so that by 1906 they were regarded as accidental wanderers. 



Sharp-Shinned Hawk {Aaoipiter striatus) - All of the sharp-shinned hawks observed 

 on the area were perched in cottonwood trees in the creek type. Three were seen 

 together during the fall migration in 1979 and one was sighted during the spring 

 migration of 1980. As it was only observed during migration it is unlikely the 

 species breeds on the area and it was therefore listed as rare. Cameron (1907) 

 listed it as "tolerably common and undoubtedly breeds," although he never located 

 a nest. Because his observations were over a wider area than this study, it is 

 unlikely his comments reflect the historical situation on this study area. 



Cooper's Hawk (Aooipiter aooperii) - One female Cooper's hawk was sighted during 

 the spring migration of 1980 perched in a small cottonwood on the edge of the 

 limber pine badlands. It is unlikely this species breeds here, consequently 

 it was listed as rare for this area. This species is of "special Interest or 

 concern" for Montana. Cameron (1907) also listed this species as rare for the 

 area having observed it only three times in sixteen years.
