Justification of Red List category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The species is described as 'uncommon' (Stotz et al. 1996). In suitable habitat, densities of at least 3-5 individuals/km² were observed (Schuchmann and Boesman 2020). Currently, about 65,000 km² within the range are covered by forest with at least 75% canopy density (Global Forest Watch 2022). Assuming that 40% are occupied at this density to account for the species' apparent rarity, the global population may number 78,000-130,000 individuals. This roughly equates to 52,000-87,000 mature individuals.

Trend justification
Due to its being restricted to undisturbed primary forest, declines are suspected on the basis of habitat loss (Schuchmann and Buesman 2020). Tree cover loss within the range is however low (2% over ten years; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Population declines are therefore likely slow, not exceeding 10% in ten years.
