Population justification: Given the species's scarcity, its population is suspected to number 2,500-9,999 mature individuals, equivalent to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.

Trend justification: Forest clearance over the past few decades has been rapid, especially in the lowlands, and as a result the extent of suitable habitat remaining is small. The species is suspected to have declined at a similar pace to habitat destruction.
