Anas acuta (VAG): occurs in Nearctic and Palearctic regions, and overwinters in tropical and subtropical areas of the Northern Hemisphere. It breeds mainly in Canada, Alaska, northern USA, Siberia, Russia and Scandinavia, and overwinters south as far as in northern South America, southern Europe, Sub-Saharan Africa, and southern and southeastern Asia (Carboneras, 1992). In Brazil, it is considered vagrant and there are only a few records in Fernando de Noronha/Pernambuco (PE) (Sick, 1997; Silva-e-Silva & Olmos, 2006; Burgos & Olmos, 2013) and exceptionally in Rio de Janeiro (RJ) (Nacinovic, 1991).
