Population justification: The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).
Densities of c.8 birds/km² have been recorded in ideal conditions in Manu National Park, Peru (Sherman et al. 2020). Even under the assumptions that the species occurs at a considerably lower density elsewhere and that only a small proportion of the range is occupied, the population must be very large, likely numbering >100,000 mature individuals.

Trend justification: The species is described as becoming rarer or absent in areas where it previously was common, likely as a consequence of habitat loss and hunting (Sherman et al. 2020).
Over the past three generations (22.5 years), 6% of tree cover has been lost within the range; since 2017 this has been increasing to a rate equivalent to 8% over three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). This species is described as sensitive to forest loss and anthropogenic disturbance (Sherman et al. 2020). Precautionarily it is therefore suspected that overall habitat loss exceeds the rate of tree cover loss by half, suggesting an overall rate of habitat loss of 9% over the past three generations and accelerating to 12% over three generations from 2017 onward.The impact of hunting on the population size has not been quantified. It is tentatively suspected that hunting contributes an additional c.5% to the rate of population decline, though an exact estimate is urgently required. Population declines are therefore here placed in the band 10-19% over three generations.
