Abstract

Abstract Parental behavior and prey deliveries at a Bald Eagle (Haliaeetus leucocephalus) nest were monitored (628 observation hours) during three breeding attempts from 1997–1999 at a nest in inland south-central South Carolina. Attendance patterns varied between adults and among breeding attempts, with reduced attendance and incubation observed during a failed attempt. During the three nesting attempts, the female was most often in attendance and incubated more than the male. The eagle pair averaged approximately 4 foraging trips per day during the successful 1997 season, but only 3 trips per day during the 1999 season. Fish and waterfowl comprised 56% and 34% of diet in 1997, respectively, with largemouth bass (Micropterus salmoides) the major fish prey and American Coots (Fulica americana) the major avian prey. Fish (primarily bass and sunfish) comprised 91% of the diet in 1999. Later nesting and reduced waterfowl populations may have contributed to increased fish prey in 1999.
