Population justification: Engblom et al. (2002) estimate the known population to be c.500 birds, with a potential total population of c.1,500. The number of mature individuals is therefore likely to fall between 250 and 999.
Trend justification: This species is suspected to lose 53.2% of suitable habitat within its distribution over three generations (11 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by Given the susceptibility of the species to fragmentation and/or edge effects, it is therefore suspected to decline by ≥50% over three generations.
