About These Birds
Grey-backed Storm-petrel
Grey-backed Storm-petrel, 16–19 cm, breeds on sub-Antarctic islands across the Southern Ocean from Tristan da Cunha to the Antipodes. Pale grey back and rump distinguishes it from most other storm-petrels. Planktivore; flutters low over the sea surface picking up zooplankton.
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.
