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

Trend justification: The species is described as very sensitive to habitat degradation (ICMBio 2018). Even though there are no exact data on the population trend, it is observed less frequently in disturbed and converted habitats (ICMBio 2018). The population is believed to be in decline as a consequence of the loss, fragmentation and degradation of forests in its range.
Over the past three generations (10.9 years), 9% of tree cover has been lost within the range; since 2017, this rate has been increasing to 11% over three generations (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Even though the species may also be found in tall secondary growth it is strictly dependent on continuous forest cover (ICMBio 2018, Schulenberg 2020). To account for additional impacts of forest degradation, fragmentation and selective logging, it is precautionarily suspected that population declines may be up to twice as high as the rate of tree cover loss alone. Therefore, declines are here placed in the band 10-19% over the past three generations, and in the band 20-29% over the next three generations into the future.
