Population justification: Based on the first-quartile and median population densities of closely-related species (3.15-11.2 individuals per km²) and the area of forest with 50% canopy cover within the species's mapped range in 2010 (c.73,000 km²; Global Forest Watch 2021), and assuming 10-25% of forest is occupied, the population size is tentatively suspected to fall within the range 23,000 - 205,000 individuals, which roughly equates to 15,000 - 137,000 mature individuals. Surveys are required to confirm the population size.

The subpopulation structure is not known, but the forest within the species's range remains mostly contiguous, so it is assumed that there may be a single subpopulation.

Trend justification: Over the past ten years to 2020, approximately 6% of tree cover with at least 50% canopy cover was lost from across the species's range (Global Forest Watch 2021). The rate of tree cover loss was higher during 2019-2020 (Global Forest Watch 2021). Projecting the 2019-2020 rate of tree cover loss forwards, 9% of tree cover may be lost from the species's range over the next ten years. This species is confined to forest, so its population size is inferred to be declining in line with forest loss. The population size may be declining at a faster rate than that of forest loss as a result of forest degradation and fragmentation, although it is known to tolerate some selective logging (Pacheco and Olmos 2005, A. Lees in litt. 2007, 2011). The population size is therefore suspected to be declining at a rate of less than 20% per decade.
