Data Zone
Justification of Red List category
This species has a very 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 population size has not been quantified, but the species is described as fairly common to common (Greeney and Boesman 2022).
Trend justification
The population trend has not been investigated, but the only threat known to the species is the logging and fragmentation of forests within the range. Tree cover loss within the range is very low (3% over three generations; Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Population declines are therefore likely equally low and localised; they are here tentatively placed in the band 1-9% over three generations.
The species occurs from Puno (Peru) to Santa Cruz (Bolivia), with most of its range lying in Bolivia.
It inhabits forests and is most commonly found at elevations of 800-2,250 m (Greeney and Boesman 2022).
Threats to the species include deforestation for the expansion of small-scale agriculture, plantations, timber harvesting and road construction (Greeney and Boesman 2022).
Conservation Actions Underway
The species occurs in several protected areas across its range.
Conservation Actions Proposed
Accurately quantify the population size. Research the species' ecology and exact habitat requirements. Research its tolerance of habitat degradation and conversion. Monitor the population trend. Protect areas of suitable habitat within the range.
