Population justification: The global population size has not been quantified, but this species is described as uncommon, or rare and local.

Trend justification: The population trend has not been estimated directly, but suitable habitat appears to have been lost at historically occupied sites (Baumann 2020). The only direct threat known to the species is the loss and degradation of its habitat. Forest loss within the range has been low over ten years (2%; Global Forest Watch 2020). Given that the species does not depend on forest, but readily tolerates edges and shrubby habitat, the rate of population decline is likely lower than the rate of forest loss. Precautionarily it is suspected that the species is undergoing a very slow population decline, the rate of which does not exceed 10% over ten years.
