Distribution and habitat

Breeds at the Falklands and other islands off southern South America, as well as in sub-Antarctic Islands, after which it disperses across the southern oceans all the way down to 65° South. Its status in southern African waters is uncertain, however it is generally scarce, occurring off the coast of the Western Cape, Eastern Cape and KwaZulu-Natal.

Movements and migrations

Little known, although it is thought to breed from about late August to February and March, so it is mainly present in southern African waters from May-October.

Food 

Generally eats larger animals than filter-feeding prions, with a diet dominated by crustaceans, fish and squid. It mainly forages at night, grabbing prey from the surface or plunge-diving up to a depth of about 3-5 metres.

Threats

Not threatened.
