Behavior Of The Red-Footed Booby (Sulasula) In British Honduras, Jared Verner
LSU Historical Dissertations and Theses
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.

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.

The eight-month study deals with the White-faced Ibis, Plegadis chihi, in southwestern Louisiana. It affirms the absence of the closely related Glossy Ibis, Plegadis falcinellus, as a breeding bird in that area today. Data on feeding habits, social behavior, nesting cycles, and plumage changes in chihi are presented as a step toward clarifying the relationship of these two puzzling forms of ibis; but the full significance of these findings cannot be ascertained until more is known about the habits of falcinellus. The most important conclusions concern plumage changes. It is shown that published descriptions of plumage and molt in chihl …
