Population justification: Partners in Flight estimate the total population to number 50,000-499,999 individuals (A. Panjabi in litt. 2008).

Trend justification: This species is suspected to lose 21.5-23.4% 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.
