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

Trend justification: This species is suspected to lose 35.4-47% 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). However, given the species shows a degree of tolerance of habitat degradation and fragmentation (A. Lees in litt. 2011), it is suspected to decline by 25-29% over three generations.
