Population justification: The global population size has not been quantified, but this species was described as 'fairly common', prior to being split (Stotz et al. (1996).

Trend justification: This species is suspected to lose 19.8-20% of suitable habitat within its distribution over three generations (14 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.
