Distribution and habitat
Breeds on sub-Antarctic islands, dispersing across the
southern oceans but generally staying below 40° South. Juveniles and immatures
may range further north, including in southern African Waters off the southern
and western coast of South Africa.
Movements and migrations
Adults return to breed at their colonies in
September, so that their chicks can fledge by May - it is present in
southern Africa from June-September.
Food
Its diet in southern African is largely unknown, but
probably consists of mainly offal and discards from fishing vessels.
Threats
Vulnerable due to continuous population decreases at
a number of its colonies, linked to mortalities on longlines.
