Antarctic Petrel
40–46 cm, wingspan 100–110 cm. Striking chocolate-brown and white pattern; only member of its genus. Breeds solely in Antarctica on cliff ledges; among the most southerly-nesting birds. Feeds on fish and krill beneath pack ice. Returns to colonies in October; one of the most abundant Antarctic seabirds.
