Brown Booby (Sula leucogaster) Science Article 10
Masked Booby (Sula dactylatra) and Brown Booby (S. leucogaster) are pantropical seabirds. These species are socially monogamous. Thus, males and females have a high investment in parental care. In this work, field observations and DNA fingerprinting were applied to investigate the breeding system of both species. Two breeding colonies located on the Brazilian coast were visited. Thirteen Masked Booby biological families, from the breeding colony of Abrolhos Archipelago (Bahia State), and twenty eight Brown Booby biological families, from the breeding colony of Moleques do Sul Islands (Santa Catarina State) were studied.
