Justification of Red List category
This species appears to have declined very rapidly on its main breeding island, possibly associated with the impacts of Hurricane Iniki in 1992, and continues to decline, with two colonies known of in the early 1980s, and possibly a third, now abandoned. Combined with longer term declines owing to a number of other threats, it qualifies as Endangered.
