Population justification: The total population is estimated at fewer than 10,000 individuals. This figure is supported by estimates for range states provided by various sources. It is placed in the band 2,500-9,999 mature individuals, equating to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.
Trend justification: The species's population is suspected to be declining rapidly, in line with forest clearance and degradation across its range.
