About These Birds
Polynesian Storm-petrel
Polynesian Storm-petrel, 25–26 cm, is the largest storm-petrel, breeding on tropical Pacific islands from the Marquesas to the Cook Islands. Two morphs: dark and white-bellied. Flies with distinctive high bounding style. Vulnerable; predated by introduced rats and cats on nesting 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.
