Population justification: The population is estimated to number 10,000-19,999 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Trend justification: The species is suspected to be declining at a slow or moderate rate, owing to deforestation within its known and suspected range.
