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.
It mainly eats fish and squid, supplemented with insects,
jellyfish and crustaceans.
Not threatened, although some colonies have greatly
decreased in size due to introduced, exploitation by humans and habitat loss.
