Distribution and habitat

Breeds on islands in the north-eastern Atlantic Ocean, tropical Indian Ocean and the Pacific Ocean, dispersing across tropical and subtropical waters in the non-breeding season. It is a rare vagrant to southern Africa, recorded in February 1986 off Luderitz, Namibia and in summer 1977 off Cape Columbine, Western Cape.

Food 

It mainly eats small fish, squid and crustaceans, doing most of its foraging by grabbing prey from the surface of the water, occasionally plunge-diving to a depth of 2.4 metres.

Threats

Not threatened, although it has been negatively affected by introduced predators at some of its breeding colonies.
