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 'fairly common' (Stotz et al. 1996).
Trend justification
The population trend has not been investigated, but the only threat thought to impact the species is the logging and fragmentation of forests within the range. While hunting may locally be occurring, the impacts on the population size are assessed as negligible (Silveira et al. 2022).
Tree cover loss within the range amounts to 10-12% over three generations (15 years; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). The species is forest dependent, and therefore population declines may be roughly equivalent to the rate of tree cover loss; they are here tentatively placed in the band 10-19% over three generations.
It has a disjunct, but wide range across large areas in northern and central South America.
The species inhabits humid lowland and montane forest, as well as dry and secondary forest (Gomes 2020, Silveira et al. 2022).
The most severe threat is the loss and fragmentation of forests through conversion for agriculture and livestock pastures (Renjifo et al. 2014, Gomes 2020). The species is locally hunted, albeit at a low level (Silveira et al. 2022).
Conservation Actions Underway
It occurs in several protected areas across its range. The species is listed as Vulnerable at the national level in Ecuador (Freile et al. 2019). Subspecies castaneus is listed as Critically Endangered in Colombia (Renjifo et al. 2014).
Conservation Actions Proposed
Quantify the population size. Monitor the population trend. Monitor rates of habitat loss. Protect areas of suitable habitat.
