Justification of Red List category
This species is listed as Near Threatened because it has an extremely small range on one island, but it remains very common. Ongoing efforts to eradicate invasive species within the range are expected to show a positive effect on the population trend; should these efforts however stop or fail, the species could quickly be driven to CR or EX in the near future. Likewise, any evidence of a decline in the population would qualify it for a higher threat category.

Population trend: unknown

Extent of occurrence (breeding/resident): 150 km2

Country endemic: yes
