Population justification: The global population size has not been quantified, but the species is described as scarce throughout its range (del Hoyo et al. 2007). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 2.4% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a decline of between 1-19% in the species' population size over the same time frame.
