Abstract: The ecology of the bald eagle (Haliaeetus leucocephalus) was studied from 1972 to 1982 in the GYE in northwestern Wyoming and adjacent Idaho and Montana. This population consisted of 3 ecological, but not genetically, distinct units. The population probably was stable at 30-31 breeding pairs from 1960 to 1970, but increased exponentially to 50 known breeding pairs from 1971 to 1982. There were 50-58 breeding pairs and a total of 180-210 bald eagles in this population in autumn 1982. Spraying of DDT for forest insect control between 1955 and 1963 apparenty depressed reproduction, recruitment and population levels in sprayed areas.
