Justification of Red List category

This species is listed as Endangered as data from South Georgia (Georgias del Sur), which holds around half the global population, indicate a very rapid rate of decline of the world population over three generations (90 years), even if colonies lacking trend information are assumed to be stable. The major driver of declines is likely to be incidental mortality in longline fisheries.
