Summary
Description
Charles L. Braley 1958 reported a drastic decline in a bald eagle Haliaeetus leucocephalus population during the late 1950s. He documented a marked reduction in the number of breeding pairs and the reproductive rate of the remaining pairs. In response to increasing concern for the future of the species, the National Audubon Society began to investigate the bald eagle over most of its range in 1960. The studies reported here have been closely coordinated with, or are integral parts of, a long term program to determine the status and examine the ecology of the bald eagle.
