Population justification: The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 9.7% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). However, the species is common and adaptable throughout it range, and its population trend is therefore considered stable.
