About These Birds
Wilson's Storm-petrel
Wilson's Storm-petrel, 15–19 cm, wingspan 38–42 cm, may be the world's most abundant bird with billions breeding on Antarctic and sub-Antarctic islands. Dark brown with white rump, yellow-webbed feet dangling below body while 'walking' on water surface. Planktivore; skims copepods and krill. Circumglobal migrant.
White-faced Storm-petrel
White-faced Storm-petrel, 18–21 cm, is distinctive — dark above but with a striking white supercilium and pale underparts; bounces across the sea surface on long legs like a clockwork toy. Breeds on islands in the North and South Atlantic, Indian Ocean, and Australia. Circumglobal oceanic migrant.
