Population justification: The population size has not been quantified in detail across the range, but the species is described as common, but probably under-recorded (Collar et al. 2020). National estimates include 180-510 mature individuals in Peru (SERFOR 2018), though based on observational records the population may be larger (see eBird 2021). In both Ecuador and Colombia, the national populations have been placed in the band 2,500-9,999 mature individuals (Renjifo et al. 2014; Freile et al. 2019). The global population is therefore inferred at 5,180-20,508 mature individuals, rounded here to 5,000-21,000 mature individuals, though this number requires confirmation.
It is inferred that no subpopulation contains more than 1,000 mature individuals (Renjifo et al. 2014; Freile et al. 2019; see also SERFOR 2018).

Trend justification: The species is inferred to be in slow decline due to the destruction and fragmentation of its forested habitat. Tree cover has been lost at 1.5% over the last three generations (10.8 years; Bird et al. 2020) across the entire range (Global Forest Watch 2021). However, rates of habitat loss may be higher locally in Colombia, amounting to up to 10% over three generations or potentially even higher (see Renjifo et al. 2014; Negret et al. 2021).
To account for locally higher rates of habitat loss and additional impacts of forest degradation on the population size, the overall rate of population decline is tentatively placed in the band 1-19% over three generations.
