About These Birds

South Georgia Diving-petrel

20 cm. Tiny; dark above, white below; paler scapular edges. Breeds South Georgia, Kerguelen, and Heard Island. Extremely abundant; possibly billions of individuals in Southern Ocean. Feeds on euphausiids by diving; sympatric with Common Diving-petrel but smaller with narrower bill.

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.
