Population justification: A. Panjabi in litt. (2008).

Trend justification: This species is suspected to lose 15-16.3% 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.
