C <br />in September, 1979. <br />No Cooper's hawk nests were located on or near the study area during the field <br />investigations in 1979. The Cooper's hawk is a tree nesting raptor, and <br />commonly nests in a large stand of cottonwoods along a stream (Call 1978). <br />Potential nesting habitat does not exist on the Nucla study area. Nesting <br />opportunities exist in the cottonwood stands along the irrigation canal lo- <br />cated approximately 11 miles east of the mine permit boundaries. <br />Rough -- legged hawk. Rough- legged hawks breed in Canada and Alaska and winter <br />throughout western United States ((.7,all 1978). One rough - legged hawk was <br />observed flying over the juniper habitat type approximately ;smile south of <br />the mine headquarters in January, 1980. This individual was probably over - <br />'wintering in the area. <br />American Kestrel. The Nucla study area occurs within the summer and breeding <br />range of the American kestrel. One kestrel was observed in the eastern boundary <br />of the study area in September, 1979. Nesting habitat of this small falcon <br />includes ledges on cliff faces (in treeless areas) and holes or cavities in <br />trees (Call 1978). No kestrel nests were located on or near the,Nucla study area <br />during field investigations in 1979. Potential nesting habitat in the study <br />area exists in the trees along the riparian habitat and in the grove of trees <br />north. east of the farmhouse. <br />Marsh hawk. The Nucla study area is occasionally ye , nr -round range of the marsh <br />hawk (Robbins et al. 1966) only one marsh hawk was observed during the field <br />activities in 1979 -1980. This individual was observed during the winter <br />passerine transects over the alfalfa habitat type. . <br />Upland Game Birds. Only two game birds appear to inhabit the study area: <br />ring- necked pheasant and mourning dove. The occurrence, distribution and the <br />seasonal use of the study area by these game birds and important game bird <br />habitat (i.e. , nesting) is discussed below for each of the species observed. <br />Ring- necked pheasant. The ring - necked pheasant is a year -round resident of <br />-38- <br />Junit 1980 <br />
