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 global population size has not been quantified, but this species is described as fairly common to common (Stotz et al. 1996, Krabbe and Schulenberg 2020).

Trend justification
Tree cover loss within the range is low (<5% over ten years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). As the species is restricted to the undergrowth of humid montane forest (Krabbe and Schulenberg 2020), it is suspected that the population is undergoing a decline, albeit likely at a very low rate.

The species inhabits the undergrowth of humid forests (Krabbe and Schulenberg 2020).

A potential threat to the species is the loss of forested habitat within its range; however tree cover loss is currently low (per Global Forest Watch 2021).
