Population justification: The population is estimated to number 250-999 mature 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 375-1,499 individuals in total, rounded here to 350-1,500 individuals.
Trend justification: During the 1990s, semi-deciduous forest in the species's range was rapidly cleared. However, illegal cultivation for the drug trade has rendered an assessment of habitat quality problematic recently. While new data are lacking, the species is suspected to be continuing to decline at a rate of 10-19% over ten years, owing to forest clearance.
