Population justification: The global population size is unknown given recent taxonomic changes.

Trend justification: This species is suspected to lose 15.5-19.4% of suitable habitat within its distribution over three generations (22 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.
