Justification of Red List category
This species has an extremely small range on one small group of islands where it is currently common. The range is not yet severely fragmented or restricted to few locations. For these reasons, the species is classified as Near Threatened. However, it could decline rapidly if alien predators such as brown tree snake Boiga irregularis were introduced, and would then warrant uplisting to a higher threat category.

Population size:

Population trend: Stable

Extent of occurrence (breeding/resident): 160 km2

Country endemic: Yes

Land-mass type - oceanic island
Realm - Oceanic
IUCN Ecosystem -- Terrestrial biome
