Population justification: The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).

Trend justification: This species is suspected to lose 6.3-6.7% of suitable habitat within its distribution over three generations (10 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.
