Population justification: The species is described as 'rare and patchily distributed' (Stotz et al. 1996). In Colombia, densities of 1-3 individuals/km2 could be observed (Renjifo et al. 2014). Assuming that this density is representative for the entire range, and assuming that only 25% of forests within the range are occupied to account for its rarity (i.e., 7,000-8,000 km2; Global Forest Watch 2022), the global population may number 7,000-24,000 individuals. This roughly equates to 4,600-16,000 mature individuals.
Trend justification: The population trend has not been investigated, but declines are suspected as this species is described as susceptible to the loss and disturbance of its habitat.
Tree cover loss within the range is low (3% over three generations; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Population declines are therefore likely equally low and localised; they are here tentatively placed in the band 1-9% over three generations.
