Population justification: The population size is preliminarily estimated to fall into the band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.
Trend justification: A rapid and on-going population decline is suspected, owing to rapid and continuing deforestation and habitat degradation across the species's range.
