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 given recent taxonomic splits. Prior to being split, the species has been described as 'fairly common but patchily distributed' (Stotz et al. 1996).
Trend justification
The population trend has not been investigated. Tree cover loss within the range is lost at a rate of 4% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Population declines are therefore likely equally low; they are here tentatively placed in the band 1-9% over ten years.
The species occurs from eastern Colombia through southern Venezuela to southwestern Guyana and French Guiana, and southward through eastern Ecuador, eastern Peru, Amazonian Brazil to northern Bolivia.
