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 c.15-18% of suitable habitat in the Amazonian portion of its range (as defined in the model, and accounting for c.93% of this species’s global extent of suitable habitat) over three generations (26 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). The species is thought to show high forest dependence, but it is unclear whether it is susceptible to fragmentation, edge-effects or persecution, thus additional declines have not been factored in for these reasons. The rate of decline over three generations is therefore suspected to be in the band 1-25%.
