1. Strip transect censuses for passerine birds and upland game birds <br /> 2. Ground surveys to determine the presence and status of raptor nests <br /> 3. Surveys of wet areas to determine presence and abundance of waterfowl <br /> and shorebirds <br /> 4. Waterfowl and upland game bird brood production surveys <br /> In addition to the above-listed specific census techniques, opportunistic <br /> sightings of raptorial birds, game birds, and waterfowl were recorded <br /> by species, habitat type, and location on wildlife observation forms during <br /> all field activities. <br /> Passerine Birds. Passerine birds were censured along transect lines placed <br /> within each of the following major vegetation types on the study area: <br /> 1. Upland sagebrush <br /> 2. Grassland pasture <br /> 3. Riparian <br /> 4. Alfalfa field <br /> 5. Juniper <br /> Transects were 0.5 km in length and were completely contained within the <br /> vegetation type being sampled (Map 11-1, Appendix A) (see Results, page 31) . <br /> For the breeding bird census, a qualified observer paced each transect and <br /> stopped every 50m to record all birds seen or heard during a five-minute interval <br /> within 25n, of the stop. The numbers of all birds seen or heard (including non- <br /> passerines) were recorded by species and habitat type. Breeding birds were <br /> censused on clear, calm, warm morning in June, 1979. Censuses were conducted <br /> for three oonsective days. <br /> JUN 1 1 1984 <br />
