About These Birds
New Zealand Storm-petrel
New Zealand Storm-petrel, 16–18 cm, was thought extinct for over 150 years until rediscovered in 2003 off the Hauraki Gulf. Breeding colony finally found in 2013 on Little Barrier Island. Dark above, white below with black stripe through belly. Endangered. Planktivore in New Zealand coastal and pelagic waters.
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.
