Procellaria aequinoctialis (MGT):nests on the Malvinas/ Falklands and South Georgia on the Atlantic Ocean. It also breeds on Prince Edward and Marion, Crozet, Kerguelen, Auckland, Campbell and Antipodes (Neves et al., 2006). It moves broadly through the three oceans between latitudes 30°S and 55°S. In Brazil, it is more common southern and southeastern coastal regions (Carboneras, 1992c). Data from geolocators and from satellite transmitters showed that ten individuals captured in South Georgia migrated to areas east of the La Plata River estuary in Argentina and wintered between February and April between Tierra del Fuego and southeastern Brazil until October,when they returned to South Georgia to breed and then lay eggs between November and December (Phillips et al., 2006). In Brazil, there are records for RS in July, August, September, November, December, April and May (Belton, 1984; MNRJ; MZUSP). In April-October at the coast of SP and RJ (Sick, 1997; MNRJ; MZUSP).There are also records for the coast of BA in April and May (WikiAves, 2016), as well as specimens collected in June-August (MZUSP; MNRJ). In PA, the records are from August and September (Sick, 1997; MPEG).
