Justification of Red List category
This species is listed as Near Threatened because it is expected to experience a moderately rapid population decline in the next three generations (33 years) owing to a number of threats including introduced predators, oil-spills, the harvest of eggs and chicks and disturbance. If the population was found to be declining more rapidly, the species might qualify for a higher threat category.
