Population justification: The global population size has not been quantified, but it is believed to be large as the species is described as locally fairly common in at least parts of its wide range (Zimmer and Isler 2003). This species is suspected to lose 22.7-31% of suitable habitat within its distribution over 15 years based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). However, given the species's tolerance of fragmentation/degradation/edge-effects and/or the extent of overall losses, it is suspected to decline by 0-25% over three generations.

Trend justification: This species is suspected to lose 22.7-31% of suitable habitat within its distribution over three generations (15 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). However, given the species's tolerance of fragmentation/degradation/edge-effects and/or the extent of overall losses, it is suspected to decline by <25% over three generations.
