Population justification: The global population size has not been quantified, but it is believed to be large, even though the species is described as well distributed but scarce (Coates 1985). This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 4.8% within its mapped range over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). It is therefore tentatively suspected that this rate of cover loss may have led to a decline of between 1-19% in the species' population size over the same time frame, with a best estimate of reduction being less than 5%.
