Population justification: The population is estimated to number 1,000-10,000 individuals, roughly equating to 670-6,700 mature individuals.
Trend justification: This species is suspected to lose 29.8-47% of suitable habitat within its distribution over three generations (54 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). However, the rate of loss outside Amazonia is likely to be lower (A. Lees in litt 2011), so the species is therefore suspected to decline by 25-30% over three generations.
