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.

Ashy Storm-petrel

Ashy Storm-petrel, 19–21 cm, is restricted to the California Current of the eastern Pacific; breeding on Channel Islands and the Farallon Islands. Entirely ashy brown without white rump — uncommon among storm-petrels. Endangered; less than 10,000 individuals; threatened by light pollution and introduced predators.
