Distribution and habitat
Breeds at Gough Island and Tristan da Cunha, after which it
disperses across the South Atlantic Ocean, mainly between 20-60° South. It is a
rare vagrant to southern Africa, with most records in the south-western corner
of the region, with other sightings off central Namibia and southern South
Africa; all were sighted between July-November.
Food
It mainly eats squid, supplemented with fish and
crustaceans, doing most of its foraging by catching prey from the water surface.
Threats
Vulnerable, largely due to human exploitation and
predation of chicks and eggs by introduced rats (Rattus) and House mice (Mus
musculus).
