Distribution and habitat
Widespread across tropical oceans, while it is a rare
vagrant to southern Africa, with most records located near KwaZulu-Natal. It is
also rarely sighted along the coast of Namibia and Mozambique.
It mainly eats fish, caught by plunge-diving, although it
also hawks flying fish aerially. It often follows dolphins and gamefish,
catching prey that they disturb.
It mainly breeds on islands in the north-west Indian Ocean
and off the coast of Brazil, nesting in colonies on steep slopes.
Not threatened, although its population has decreased
recently due to human exploitation.
