Limosa haemastica (MGT):after breeding in the Arctic, a large part of its population gathers along Hudson Bay and James Bay in Canada between late July and mid-August (van Gils & Wiersma, 1996). The species crosses the Atlantic and reaches northern South America, including the Amazon Basin, at the Sustainable Development Reserves of Mamirauá (Melo et al., 2011), Amanã (Santos et al., 2011) and Piagaçu-Purus (Cintra et al., 2011), Anavilhanas National Park (Cintra & Rosas, 2011), Alto Guaporé region (d'Horta, 2011) and the Pantanal (Poconé/ MT; Cintra, 2011) between September and November. From October to April, the species reaches southern Brazil in SP, PR, SC and RS (Vallejos et al., 2011; Krul et al., 2011; Ferreira et al., 2011; Fedrizzi & Carlos, 2011; Dias, 2011; Barbieri, 2011; MZUSP), in addition to Uruguay and Argentina. Over 1,000 individuals use the Lagoa do Peixe National Park as a stopover site during migration (Belton, 1994; Nascimento, 2011), but their main wintering areas are in extreme southern South America, Tierra del Fuego and southern central Chile.The young appear to depart after the adults, and the return to the north from April onwards is completed with use of little or no (Harrington et al., 1986) stopover sites (van Gils & Wiersma, 1996).
