Justification of Red List category
Although this species is not well known, surveys at sea and at one breeding colony suggest that its population size and range are above the thresholds for listing the species as threatened under Criteria B, C or D and we have no evidence to suggest that it is declining at a rate that would approach the threshold for threatened under Criterion A. However, the area of its breeding colonies is small and highly uncertain and the species may be declining as a result of light pollution. For these reasons, the species is listed as Near Threatened.
