Population justification: Vale et al. (2007) extended the extent of available habitat to 723 km2. Assuming a population density of 80 individuals / km2 gives a total population estimate of c.15,000 individuals, so it is placed in the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Trend justification: This species is suspected to lose 100% of suitable habitat within its distribution over three generations (20 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). Given the susceptibility of the species to fragmentation and/or edge effects, it is therefore suspected to decline by ≥80% over three generations.
