Population justification: The global population size has not been quantified, but the species is described as rather common (Konig et al. 1999). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 1% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). The population trend is therefore considered stable.
