Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but this species is described as uncommon to locally fairly common (Stotz et al. 1996, Krabbe and Schulenberg 2020).
Trend justification
Within the range, tree cover is lost at a rate of 3-4% over three generations (10.8 years; Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). As the species is restricted to forests (Krabbe and Schulenberg 2020), population declines may be roughly equivalent to the rate of tree cover loss; declines are therefore here tentatively placed in the band 1-9% over three generations.
The species occurs in the Amazon basin from southeastern Colombia through eastern Ecuador and Peru to northern Bolivia and west-central Brazil.
The species inhabits humid 'terra firme' forest (Krabbe and Schulenberg 2020).
The species is threatened by the loss of forested habitat, which is occurring locally within the range (Krabbe and Schulenberg 2020, Global Forest Watch 2022).
