Use of Communal Roosts and Foraging Areas by Bald Eagles Wintering in the Klamath Basin
Keister GP, Anthony RG, O'Neill EJ. 1987. Use of Communal Roosts and Foraging Areas by Bald Eagles Wintering in the Klamath Basin. The Journal of Wildlife Management. 51(2):415-420
Patterns of use of 5 communal roosts and 3 feeding areas by bald eagles (Haliaeetus leucocephalus) in the Klamath Basin of southern Oregon and northern California were investigated during the winters of 1978-79 and 1979-80. Bald eagles arrived in late October and were most abundant during late January. Counts peaked at approximately 500 eagles, which constitutes one of the largest wintering concentrations in the lower 48 states. Numbers declined from February through March. There were several major shifts in use of roosts and feeding areas within and between years, which depended on the location of an accessible food supply (mainly waterfowl), which in turn was affected by weather, season, and human activities Comparisons in bald eagle behavior are made between several locations, and common aspects are described.
