Distribution and habitat
Occurs across tropical oceans, extending through the
Mozambique Channel to the area off the coast of KwaZulu-Natal, occupying both
coastal and oceanic areas. It is rarely recorded inland in southern Africa, in
south-eastern Zimbabwe, Gauteng and the Free State Province.
Movements and migrations
Little known. Juveniles and adults are highly mobile, even though they tend to
move at just 9-10 km/h.
Food
It mainly eats flying fish and flying squid, doing most of
its foraging at sea, using its hooked bill to hawk prey aerially or from the
surface of the water. It also regularly kleptoparasitises other seabirds, using
a technique where it grabs the other birds tail which causes it to regurgitate
food which it then grabs. The following food items have been recorded
in its diet:
- Vertebrates
- fish
- Sterna fuscata (Sooty tern
nestlings)
- Chelonia mydas (Green turtle hatchlings)
- squid
- flying squid (Ommastrephidae)
Breeding
Breeds on islands, with the largest colonies on Europa
Island, Mozambique Channel (just outside southern African waters) and Aldabra
Atoll, Seychelles. It typically places its nest on top of a shrub or tree,
rarely on a cliff or the ground.
Threats
Not globally threatened, although many of its colonies are
decreasing in population due to human exploitation, habitat loss, disturbance
and introduced predators - it is now nearly extinct in the Atlantic Ocean.
