Distribution and habitat

Breeds at tropical and subtropical islands in the Indian and Pacific Ocean, after which it disperses across much of these two oceans, largely excluding the area between South-East Asia and Australia and marginally extending into southern African waters. Here it is generally uncommon off Mozambique and north-eastern KwaZulu-Natal, with two vagrant records off the Eastern Cape and close to the coast of central KwaZulu-Natal.

Movements and migrations

Disperses across tropical and sub-tropical waters around its breeding colonies; it is mainly recorded in southern African waters in the period from August-March.

Food 

It mainly eats fish and squid, supplemented with insects, jellyfish and crustaceans.

Threats

Not threatened, although some colonies have greatly decreased in size due to introduced, exploitation by humans and habitat loss.
