DOWNLOAD EBOOKBald eagles (Haliaeetus leucocephalus) associate with wintering waterfowl concentrations throughout the United States, but little detailed information is available on eagle-waterfowl relations. This report concerns the ecology of bald eagles wintering in the vicinity of Swan Lake National Wildlife Referenc in north-central Missouri and, more specifically, examines the association of the eagles with waterfowl during the winters of 1975-76, 1976-77, and 1977-78

DOWNLOAD EBOOKDepletion of fisheries due to acid rain may pose a future threat to bald eagle and osprey populations in some regions. Loss of essential habitat has affected declines in the caracara and western burrowing owl and the disappearance of the norther aplomado falcon from the southern United States. Most populations of the ferruginous hawk, marsh hawk, and prairie falcon appear stable; habitat loss is the most critical factor in population changes.
