Justification of Red List category
This species has a very small population, on two tiny islands, and owes its survival to the existence of several areas which are difficult to access by hunters and introduced grazers, and resistant to colonisation by rats. However, as a direct result of conservation action on Nuku Hiva and the translocation of birds to Ua Huka, the population is increasing slowly overall, and the establishment of a second population qualifies this species as Endangered.

Generally Oceanic islands are islands or island groups that are <200,000 sq km in size and separated from other land masses by >200 m sea depth.
