The White-headed Petrel is a large seabird that breeds on islands in the Southern Ocean. Its white head and dark eye patch stand out, and it flies long distances to feeding grounds at sea.
It has a white head, a dark patch around the eye, long narrow wings, and a pointed tail. The back is pale gray, with darker gray on the upperwings and rump; most of the underside is white.
It is nocturnal at breeding colonies and raises one egg in a burrow dug into peaty soil. Both parents take turns incubating it for 55 to 60 days.
