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.

Monteiro's Storm-petrel

Monteiro's Storm-petrel, 19–21 cm, breeds exclusively on Graciosa Island in the Azores, wintering in the central North Atlantic. Recently split from Band-rumped Storm-petrel; breeds in a different season (July–November vs March–April for Castro's). Near Threatened; very small island-restricted population.
