Resumo em Inglês:
ABSTRACT Fernando de Noronha Archipelago is one of the places with the highest richness of seabirds in Brazil; however, little information about the breeding biology of many species is available. Here we report a breeding colony of the Masked Booby (Sula dactylatra) in the main island of Fernando de Noronha, and present new data about the natural history and breeding biology of this species.
