Golden Eagle . The nest located on the proposed mining area in 1977 

 fledged two young in 1978, 



Marsh Hawk . The nest located on the silver sagebrush breeding census 

 plot fledged 6 young in 1978. Although territorial pairs were observed 

 elsewhere on the mine study area, no additional nests were discovered. 



Prairie Falcon . Adults were seen in 1978 near the 1977 nest site 

 and elsewhere on the mine study area, but the nest site itself was not 

 visited. 



Peregrine Falcon . A possible but unverified sighting was made 

 May 18, 1978 near the cottonwood grove in the southern quarter of the 

 proposed mining area. 



Sharp-Tailed Grouse . Attendance at grounds Nos. 6 and 7 (WBS) was 

 10 and 5, respectively, on April 20, 1978. Eight additional birds were 

 seen at a possible lek roughly 0.8 km (0.5 mi) northeast of lek No. 6 

 on this same date. 



Sage Grouse . No sage grouse were observed in the mine study area 

 in 1978, and no indications of breeding were noted, although lek No. 4 

 (WBS) was not visited. 



Ring-Necked Pheasant . A nest with 17 eggs was discovered on the 

 silver buffaloberry - silver sagebrush breeding bird census grid on the 

 proposed mining area. General observation indicated that populations 

 had declined markedly from 1977, probably due to the severe winter 

 weather and to heavy snowfall during the winter of 1977-78. This ob- 

 servation was supported by roadside survey data, which indicated a sig- 

 nificant (p < .01) decline from 1977. 



Great Horned Owl . A nest with three young was discovered in a 

 silver buffaloberry shrub in the proposed mining area near the eastern 

 boundary. Another nest with two young was found along the Prairie 

 Elk Route at the Flying V Creek crossing; the same nest had been used 

 by a red-tailed hawk pair in 1977. 



Burrowing Owl . At least six active nests were found in the 

 reconnaissance area; however, none were found in the mine study area.
