Population justification: The global population size has not been quantified, but this species is described as overall common or fairly common, though scarce in Argentina (Pearman and Areta 2020, Silveira et al. 2023). Given the frequent records within its very large range (eBird 2023), the population is unlikely to be small.
Trend justification: Large parts of forest within the range is lost, and slow population declines are suspected on the basis of ongoing deforestation and forest fragmentation.
Tree cover loss within the range amounts to 8% over ten years (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). This value does not account for additional impacts of habitat degradation on the population size. Even though the species tolerates a certain level of disturbance (Silveira et al. 2023), population declines are suspected to be roughly equivalent to the rate of tree cover loss. Tentatively, they are here placed in the band 1-19% over ten years.
