Population justification: The population has not been quantified. This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 2.2% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). As it is relatively adaptable, the species' population size is therefore likely to be stable.
