Abstract:Several persons have recently investigated the effects of various types of human disturbance, including research methods, on the productivity of bald eagles (Haliaeetus leucocephalus). This paper presents data on the behavior and productivity of bald eagles in response to climbing to nests to band nestlings in northwestern Ontario during 1966-68. Nests in 24 territories in 1966, and nests in an additional 12 territories in 1967, were climbed to. Subsequent productivity (1967-68) of these territories did not differ significantly (P > 0.05) from that of 54 territories in 1967 and 64 territories in 1968 which were censused only from a distance with the aid of binoculars. The percentage of territories with young during 1966-68 varied between 53 and 74, and the number of young per nest with young ranged from 1.4 to 1.7.
