Population justification: The global population size has not been quantified, but the species is described as locally rather abundant (Konig et al. 1999).

Trend justification: This species is suspected to lose 10.8-13.6% of suitable habitat within its distribution over three generations (21 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.
