• hawks (Accipiter cooperit). Those nests were at scattered locations throughout the area. Given <br />their spacing, it is possible that the nests were in eighteen different raptor territories. <br />The other two nests in the area were cliff nests. Those nests were very close to each other, <br />in a single golden eagle territory (Section 7, TSN, R87W). When those nests were checked on <br />18 June, it was evident that they had not been used by a nesting pair of eagles in 1996. <br />Sandhill Crane Activity <br />A pair of cranes was observed along drainages SW'/a Section 4, NW t/ and NEt/a Section <br />9, TSN, R87W in April. Although the birds were feeding and walking together, but no courtship <br />displays were observed. No cranes were observed when those areas were checked in June. <br />Apparently, no cranes nested in the Yoast area in 1996. <br />Loggerhead Shrikes <br />No shrikes were seen during baseline surveys in 1993, and extensive searches in June 1996 <br />• failed to yield any sightings. Although the interspersion of mountain brush and meadows seems <br />suitable for shrikes, they apparently do not occur at Yoast. It is possible that the available open <br />aeeas aze too limited to attract shrikes. The elevation at Yoast (> 6,800 feet ASL) also probably <br />influences shrike occurrence. Andrews and Righter (1992) noted that shrikes are rare above 6,000 <br />feet in Colorado. <br />LITERATURE CITED <br />Andrews, R. and R. Righter. 1993.
