Justification of Red List category
This species has a small breeding range and a relatively small population which is undergoing an extremely rapid decline, largely related to low adult (and immature) survival rates. Main threats are fisheries by-catch at sea and predation at breeding colonies by introduced mammals. Population models predict over 90% decline in three generations with an average extinction time of about 60 years, hence qualifying the species as Critically Endangered.
