Population justification: The population on Nuku Hiva was estimated at about 200 individuals in recent surveys and is probably increasing: it is easy to locate in place where it was absent before, including near habitations. The recently established population on Ua Huka has already increased to 46 individuals but further surveys are needed. The population is estimated as at least 300 individuals, roughly equivalent to 250 mature individuals (C. Blanvillain in litt. 2016).

Trend justification: Surveys indicate that the population on Nuka Hiva is stable or increasing slightly. The reintroduced population on Ua Huka is slowly increasing.
