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

Trend justification: This species is projected to lose 25.3-29.3% of suitable habitat within its distribution over three generations (15 years) from 2002, based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected that it will decline by 25-29% over this period.
