The most common petrel in southern African seas during the southern winter, common offshore in southern Australian waters April-November and present in New Zealand waters year-round north to Cook Strait.
There are two subspecies, separable at sea in fresh plumage:
Breeds colonially on high inaccessible ledges on islands and Antarctic coasts during August to March, otherwise at sea. Highly gregarious at all times and one of the most frequent follower of ships. Quarrelsome and noisy at fishing vessels and whale carcasses.
Similar to Fulmarus with stiff-winged glides interspersed with rigid wingbeats, high and towering in strong winds. Feeds from surface in bouyant flight and treads water like storm-petrels.
Breeds October-April, varies according to latitude. Nest is a slight scrape on rock ledge or crevice. Single white egg (63 x 43mm), incubated by both sexes for 45-50 days. Chick fledges in about 42 days.
Planktonic crustaceans, cephalopods and small fish. Also scavenges at carcasses and at fishing or whaling vessels.
Voice: Whirring cooo at nest, harsh cackling calls at sea.
