About These Birds

Ainley's Storm-petrel

Ainley's Storm-petrel, 19–21 cm, is a recently described species breeding on the Channel Islands off California, present in winter — unusual among storm-petrels which typically breed in summer. Dark overall, white rump with central grey stripe. Vulnerable; small population and restricted range.

Fork-tailed Storm-petrel

Fork-tailed Storm-petrel, 20–23 cm, is a distinctive pale grey storm-petrel of the North Pacific, breeding on islands from California to Japan. Pale blue-grey body, dark wing tips, forked tail. Unlike most storm-petrels, feeds largely on fish and marine debris rather than zooplankton alone. Winters offshore.
