Abstract

During the spring of 1969 and 1970, 28 Golden Eagle eyries in four locales in central Utah were observed to determine the prey utilized during the nesting season. Visits were made every two weeks to the eyries. Prey were removed from the nests upon counting to avoid recounting at the next visit. Sixteen species of vertebrates were found as prey for nesting Golden Eagles. Mammals comprised 96 per cent of the prey, and lagomorphs alone accounted for 92 per cent. The blacktail jackrabbit occurred as 77.8 per cent of all prey items. Avian species constituted 3.9 per cent of prey items brought to the nests. Game animals utilized as prey were exclusively birds, and accounted for 2.7 per cent of all prey. No remains of domestic animals were found in the nests.
