Population justification: The global population size has not been quantified, but the species is reported to be locally common on Sulawesi and common on Taliabu (Coates and Bishop 1997).

Trend justification:

This species may benefit from the alteration of habitats owing to human activities, thus its population is suspected to be increasing.
