Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).
Trend justification: This species is suspected to lose 15.1-24.4% of suitable habitat within its distribution over three generations (35 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.
