Taxonomy

Taxonomic note

Population justification: The global population size has not been quantified, but this species is described as 'rare' (Stotz et al. 1996).

Trend justification: This species is suspected to lose 23.0-25.7% of suitable habitat within its distribution over three generations (13 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). However, the species is thought to be highly susceptible to fragmentation, and it is therefore suspected to decline by 30-49% over three generations.
