About These Birds
Slender-billed Prion
25–26 cm. Slenderest-billed prion; pale blue-grey with faint M-mark and narrow dark breast-side patches. Breeds Falkland Islands, Kerguelen, Crozet. Feeds mainly on copepods by surface-seizing rather than filter-feeding. Slightly longer wings give more buoyant flight.
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.
