During 1971-75, a study of great horned owls and red-tailed hawks was undertaken on a 8373-ha acre in southern Wisconsin (43º 10'N, 88º 50'W). The objectives of the study were: (1) to determine demography (numbers, distribution, and reproduction), food habits, and behavior of great horned owls and red-tailed hawks; (2) to examine the impact of these raptors on pheasants, cottontail rabbits, and small mammals; and (3) to formulate management practices that would possibly reduce predation on pheasants by raptors.
