Taxonomy

Taxonomic note
Previously (Handbook of the Birds of the World and BirdLife International 2022) placed in Philydor but moved to current genus following Derryberry et al. (2011). Subspecies diluvialis may represent E extreme of clinal variation of nominate; more thorough analysis required. Two subspecies tentatively recognized.

Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996). This species is suspected to lose 15.1-16.9% of suitable habitat within its distribution over 14 years based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by under 25% over 10 years.

Trend justification: This species is suspected to lose 15.1-16.9% of suitable habitat within its distribution over three generations (14 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by <25% over three generations.
