Population justification: The global population size has not been quantified, but this species is described as 'rare' (Stotz et al. 1996). Based on this rarity and its narrow altitudinal range, it is suspected that the population numbers less than 10,000 mature individuals and is thus here tentatively placed in the band 2,500-9,999 mature individuals. An accurate quantification of the population is however urgently required.

Trend justification: While a direct quantification of the population trend is lacking, the species is feared to be in slow decline as a consequence of habitat loss. Within the range, 2% of tree cover has been lost over the past ten years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Even though the species is restricted to mature forests, population declines are therefore not thought to exceed 10% over ten years.
