Population justification: The species is described as fairly common to common in suitable habitat (Harvey 2020). Assuming that the species occurs at the same density as congeners (1-22 individuals/km2; Santini et al. 2018), the population may number roughly 3,650-80,000 individuals, equating to 2,400-53,500 mature individuals.

Trend justification: The population trend has not been assessed directly. Forest loss within the range has been very low over the last ten years (potentially < 3%; Global Forest Watch 2020), and large areas still seemed pristine (Mee et al. 2002, Harvey et al. 2011). As the species is not confined to forest interior, but also occurs at edges and in scrub habitat, the low rates of forest loss are unlikely to impact the population size, and the species is tentatively assessed as stable.
