Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996) or common .

Trend justification: This species is suspected to lose 45.6-57.8% 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). Although the species shows a degree of tolerance of habitat degradation and fragmentation (A. Lees in litt. 2011), it is nevertheless suspected to decline by 50-79% over three generations.
