Identification
A very large storm-petrel with large broad wings and a long forked tail. White rump and throat patch are often strikingly obvious, even with brief views. Pelagic, but occurs in groups near colonies. Combination of stark black-and-white plumage, relatively large size, white throat patch, and long gliding flight with periodic surface bounces is diagnostic. Silent at sea.
