Nest Success and Distribution <br />In August sandhill cranes occurred in A (a pair of adults); <br />B (two adults and .one juvenile); E (two adults and 'two <br />juveniles); F (two adults); and H (two adults and one <br />juvenile). The distribution of these cranes is definite <br />based on repeated sightings. From an aerial survey on 10' <br />August, three cranes were observed in C but were not <br />observed again. <br />All of the cranes foraged mainly in the fallow fields, <br />followed by riparian (grass) habitats in the drainages and <br />along Fish Creek, grain fields, and, lastly, in sagebrush- <br />grass. Foraging patterns in riparian and sagebrush-grass <br />were somewhat different from foraging in fallow and grain <br />fields. In the latter, the cranes would move slowly through <br />the fields, then stop and continually probe a small area for <br />up to an hour. In the riparian and sagebrush-grass, search <br />and feeding was a consistent slow movement. When the birds <br />stopped in these .habitats; they preened or loafed. As <br />reported by Bieniasz (1979), the cranes remained in a 0.8 km <br />radius of their drainage with some overlap. Cranes in E <br />overlapped with F, and F overlapped with H, as shown on the <br />enclosed map. During the first August sample, one group of <br />cranes would not tolerate another group in their territory. <br />During the second sample, the cranes from F and H foraged <br />together for 2.5 hrs., then separated and foraged in their <br />respective areas. <br />9 <br />
