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.

Black Storm-petrel

Black Storm-petrel, 22–23 cm, is the largest entirely dark storm-petrel of the eastern Pacific, breeding on San Benito Islands and Coronado Islands off Baja California. Deeply forked tail; languid, loping flight distinctive among storm-petrels. Planktivore and piscivore. Near Threatened; small breeding population.
