Justification of Red List category
This species has an extremely small area of occupancy since its breeding area consists of a strip of foredunes on a 1-km-long beach on a single island. The species is considered to occupy a single location at risk from the plausible threat of predator incursion causing a rapid population decline. Recent storm surges have destroyed portions of the species's dune breeding habitat. These events are ongoing and have become increasingly frequent since 2003, and as such the area, extent and quality of habitat can be considered to be undergoing continuing decline. For these reasons, this species is listed as Critically Endangered.
