Phaethon rubricauda (VAG):occurs in the eastern and western Indian Ocean and in the central, western and southern Pacific Ocean. Its migration is irregular. Some adults can be observed near breeding colonies all year round. Populations from the south may perform transequatorial migrations quite regularly, as they follow warm currents to the east coast of the continents (Orta, 1992a). The species occurs occasionally in Brazil and is considered vagrant: there is only one record in the Abrolhos Archipelago/BA (Couto et al., 2001).
