Chionis albus (MGT)   : breeds on the Antarctic Peninsula, on South Shetland, Elephant, South Orkney and South Georgia islands and probably on South Sandwich Islands ( Harrison,1983). Most individuals depart from the breeding site between late April and early July and although its migratory routes are little known, its main wintering areas seem to be the Malvinas /Falklands, Tierra del Fuego and southern Patagonia, with some individuals reaching Uruguay ( Burger, 1996). Burger (1996) suggests that this species is vagrant in Brazil, as Accordi & Hartz (2013) classified it for RS, where it was recorded for the first time in May 1973 ( Belton, 1974). However, its occurrence is limit- ed to the period between April and August in the southern states of PR, SC and RS ( Dias et al., 2010a), which is also illustrated by photographic records available for RS (WikiAves, 2016).
