Population justification: This species is poorly known, but is common on at least some of the islands where it occurs. Overally the population is assumed to be moderately small. It is placed in the band 10,000-19,999 individuals, equating to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Trend justification: The population is suspected to be in decline owing to on-going habitat destruction.
