• pairs actively maintain more than one nest during a breeding season (Brown <br />and Amadon 1968, Call 1978). Therefore, the five nests located in the <br />vicinity of Axial may have been constructed by the pair which occupied the <br />one active nest in this area. Likewise, the four golden eagle nests <br />located in the vicinity of Mount Streeter may also be those of the single <br />breeding pair which utilized the one active nest at this location. No <br />evidence of efforts to repair satellite nests around each of these two <br />active nests was observed. Several of these nests were noted to be in bad <br />repair and no new greenery was apparent during the aerial raptor survey on <br />May 10, 1984. Similarly, no evidence of recent activity was observed in <br />the three golden eagle nests located at the mouth of the Wilson Creek <br />Canyon (5.28, T4N, R93W). <br />Migratory Birds of High Federal Interest <br />Twelve migratory birds of high federal interest are listed (USFWS 1980) for <br />the Green River-Hams Fork coal production region (Table 4-6). All of the <br />• species, with the exception of the canvasback (Aytha valisineria), <br />long-billed curlew (Numenius americanus), black tern (Chlidonias niger), <br />and peregrine falcon (Falco peregrinus) are considered residents or <br />breeders in Latilong 2 (Craig) which encompasses the study area (Kingery <br />and Graul 1978). The first three exceptions above are migrants only in <br />Latilong 2, and the peregrine falcon is not listed as occurring in the <br />Craig Latilong (Kingery and Graul 1978). <br />Uf the 12 species listed as migratory birds of high federal interest, only <br />the golden eagle (Aquila chrysaetos) and bald eagle (Haliaeetus <br />leucocephalus) were observed within the study area during field studies. <br />Prairie falcons (Falco mexicanus), sandhill cranes (Grus canadensis), and <br />great blue herons (Ardea herodias) were observed during regional surveys <br />outside the study area; of these three species, only the heron was common. <br />Sightings of peregrine falcons during the 1970s (BLM 1981) suggest the <br />species is uncommon in the vicinity of the study area. <br />• Golden eagles were common during all seasons, however no nests were located <br />within the study area. Several active and inactive golden eagle nests were <br />4-30 <br />
