Justification of Red List category
Previously assumed to have been Extinct following the lack of records since three specimens were collected in the 1800s, this species was spectacularly rediscovered in 2003, with multiple annual records subsequently. Although there is very little information on which to base an assessment, the species has been precautionarily classified as Critically Endangered on the basis of an extremely small population which could be susceptible to the impacts of introduced predators. Tentative population estimate (based on recaptures on land and re-sightings of banded birds at sea) indicate a bigger population than was thought which may well lead to a revision of the criteria triggered and the category to which it is assigned.
