Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).
Trend justification: Prior to being split, this species was suspected to lose 16-18.6% of suitable habitat within its distribution over three generations (15 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by <25% over three generations.
