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.

Markham's Storm-petrel

Markham's Storm-petrel, 22–23 cm, is a large all-dark storm-petrel breeding in the Atacama Desert of Chile and Peru — one of the few seabirds to nest in desert habitat far from the coast. Poorly known. Near Threatened. Pelagic over the Humboldt Current and cold eastern South Pacific waters.
