About These Birds
Band-rumped Storm-petrel
Band-rumped Storm-petrel, 19–21 cm, breeds on Atlantic and Pacific volcanic islands including the Azores, Canaries, and Galápagos. Sooty brown with a white rump band; similar to Leach's but straighter wingtips and steadier flight. Multiple cryptic species may be involved. Planktivore; widespread pelagic.
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.
