Population justification: This species's population is thought to number fewer than 10,000 mature individuals (A. Bodrati in litt. 2010, G. Kohler in litt. 2010, M. Lammertink in litt. 2010, A. E. Rupp in litt. 2010, Lammertink et al. 2012) and is thus placed in the band 2,500-9,999 mature individuals; however, this may well be an overestimate given the species's apparent scarcity at well observed sites (M. Lammertink in litt. 2010). This estimate equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.

Trend justification: Although rates of deforestation in its range are thought to have decreased in recent years (R. Clay in litt. 2007, A. Bodrati in litt. 2010, G. Kohler in litt. 2010), this species's population is still suspected to be undergoing a rapid decline on the basis of continued habitat destruction, degradation and fragmentation.
