Total Length: 79 to 89 cm (Ref. 8812). Total annual breeding population of some 362,000 pairs representing about 1,200,000 to 1,400,000 birds (Ref. 84934). Occurs over open ocean (Refs. 356, 122680). Mainly feeds at night and often far from breeding colony. Forages with conspecifics, but rarely with other species. Seizes prey from the surface while sitting on the water. Scavenges on carrion and follows fishing boats. Diet consists mainly of squid as well as deep-water crustaceans, fish and flyingfish eggs (Ref. 122680).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Breeding birds arrive at the islands in the first week of November, egg laying starts late November to early December. Eggs start to hatch in late January to early February, and by the second week of August all birds have fled the island (Ref. 96995).
