About These Birds
White-vented Storm-petrel
White-vented Storm-petrel, 15–17 cm, is a small, poorly known storm-petrel of the eastern South Pacific. Dark above with white rump and white vent. Pelagic off the coasts of Peru, Chile, and Ecuador; breeding grounds discovered only recently on tiny Patagonian islands. Planktivore.
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.
