Phoenix Adaları Fırtınakuşu Pterodroma alba

A long-winged petrel, predominantly dark with a gleaming white belly. Throat patch often shows pale speckling, and birds sometimes appear distinctly pale-throated. Key identification feature is the prominent pale bar at the leading edge of the dark underwing between the elbow and body. Similar in pattern to Tahiti Petrel, but much smaller-billed and sometimes shows a pale throat. Usually flies with wings bent at the elbow, unlike the remarkably straight-winged Tahiti Petrel. Silent at sea.
