Population justification: The species is described as widespread, and locally common; its population is estimated to number at least 10,000 individuals in total, roughly equivalent to 6,700 mature individuals. This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 10.5% within its mapped range over the past 10 years (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 11-14%.
