Abstract

During three months of the breeding season in a colony of 3500 Red-footed Boobies (Sula sula) on 45½-acre Half Moon Caye, fifty miles east of Belize, British Honduras, that species’ little-known breeding activities were investigated. Feeding flights of boobies began leaving the caye before daylight and returned in the evening until after dark. Wind direction and velocity notably affected the mode of the birds’ departure but little affected their direction. Average flight-unit size was 2.41 birds. Contrary to published accounts, the boobies were able to take flight from the ground.
