Population justification: This species is generally uncommon throughout its range and hence, the population is not thought to be large. It is placed in the band 10,000-19,999 mature individuals, equating to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals. This preliminary estimate requires clarification.

Trend justification: The population is suspected to be in decline owing to on-going forest clearance and degradation.
