Population justification: The global population is estimated to number 2,000,000 mature individuals (Partners in Flight 2019).
Trend justification: The species is undergoing a slow decline (Partners in Flight 2019). Within the range, tree cover is lost at a rate of up to 12% over ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). As the species occurs in a variety of habitats, including forests, woodlands and secondary scrubland (Greenlaw 2020), the rate of population decline is likely lower than the rate of tree cover loss. It is here tentatively placed in the band 1-9% over ten years.
