Stercorarius antarcticus

Description

Stercorarius antarcticus (MGT):

occurs below the Tropic of Capricorn on southern seas and reaches Tierra del Fuego, the Antarctic Peninsula and New Zealand. The subspecies S. a. antarcticus is more frequent in Brazil; it breeds on the Malvinas/Falklands and in southeastern Argentina and overwinters in the open sea in southeastern South America (Furness, 1996). Individuals from the subspecies S. a. lonnbergi, which breed on the islands of the Austral Ocean, in the Antarctic Peninsula and islands south of New Zealand, were recovered in RS, SC, PE, AL and CE (Sick, 1997; Olmos, 2002a). Most populations probably remain near their breeding areas, but especially those located more to the south are considered migratory (Olmos et al., 2006). Photographic records for Brazil are centered in the winter and they document the species' presence in BA in May, PR in June and September, SC in August and RS between June and October (WikiAves, 2016) and occasionally on the coast of MA (Hurtado et al., 2012).
