Population justification: This species is poorly known; the total population is estimated to number 1,000-4,999 mature individuals, roughly equivalent to 1,500-7,500 individuals in total.
Trend justification: This species is suspected to lose 19.8-27% of suitable habitat within its distribution over three generations (44 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.
