Population justification: The global population is estimated to number fewer than 50,000 mature individuals (Partners in Flight 2019), thus it is here placed in the band 20,000-49,999 mature individuals. The species is described as 'uncommon' (Stotz et al. 1996).

Trend justification: The species is undergoing a moderate decline (Partners in Flight 2019). Within its range, tree cover has been lost at a rate of c.5% over the past ten years (Global Forest Watch 2020). Assuming that tree cover loss continues at the same rate into the future and population declines are proportional to tree cover loss, the species may be declining at <10% over ten years.
