Population justification: This species is described as uncommon (Stotz et al. 1996). Based on the recorded population density of one individual/km2 in Peru (Terborgh et al. 1990) and the area of the species's mapped range (3,800,000 km2), and assuming that 10-12% of the range is occupied, the population is estimated to fall within the band 392,500 - 429,800 individuals, roughly equating to 261,600 – 286,500 mature individuals. Therefore, the species is placed here in the band 100,000 – 499,000 mature individuals.
Trend justification: This species is suspected to lose 29.5-36.8% of suitable habitat within its distribution over three generations (20 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). Given the susceptibility of the species to hunting and/or trapping, it is therefore suspected to decline by ≥ 30% over three generations. An analysis of deforestation between 2000 and 2012 found that forest within the species's range was lost at a rate equivalent to 10.9% over three generation lengths (Tracewski et al. 2016).
