Distribution and habitat

Breeds on tropical oceanic islands, including Madagascar and New Guinea. It is a rare vagrant to southern Africa, with most records in the period from October-March along the coast of Mozambique and South Africa. It generally spends most of its time out to sea in the non-breeding season, so all seven southern African records are of birds in mixed-species roosts.
