Population justification: The global population size has not been quantified, but the species is described as fairly common on most islands in its range, although rare on Aneityum, and recent observations on Santo found it to be very common in all habitats and at all altitudinal levels.

Trend justification: Although it apparently remains common in all habitats on Santo, it is suspected to be slowly declining owing to habitat loss and degradation reducing the number of large trees.
