Population justification: The population size has not been quantified. The species apparently occurs at low density; it is described as uncommon at known sites and may be among the rarest bird species in Peru (Schulenberg et al. 2007, Zambrano 2021). Based on the low number of observational records from few localities within the range (per eBird 2023), the population very likely numbers less than 10,000 mature individuals. It is here tentatively placed in the band 2,500-9,999 mature individuals, but the true population size may be substantially smaller (see SERFOR 2018). An exact quantification is urgently required.

Trend justification: The population trend has not been investigated. However, as a consequence of ongoing loss, degradation and fragmentation of habitat a slow population decline is suspected.
