Justification of Red List category
This species was extirpated from its native range in 1987 following catastrophic declines owing to predation by the introduced brown tree-snake. A captive population survived and individuals have been released on the islands of Rota and Cocos. Only the Cocos island population is considered to be self-sustaining; the area of this island is tiny, so the population must be extremely small. For this reason, the species is listed as Critically Endangered.

Population size: 1-49 mature individuals
