Population justification: The global population is suspected to number 50,000-499,999 mature individuals (Partners in Flight 2020). The species is described as 'fairly common' (Stotz et al. 1996).

Trend justification: The species is undergoing a decline as deforestation is leading to local reductions and even extinctions (Hilty 2020, Partners in Flight 2020).
Over the past three generations (10.8 years; Bird et al. 2020) 18% of tree cover has been lost within the range (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Since 2016 tree cover loss has been accelerating however, to a rate equivalent to 23% over three generations (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species is largely confined to the interior of humid and wet forests (Hilty 2020); therefore population declines may be steeper than forest loss alone: It is precautionarily suspected that forest degradation causes an additional 5% of habitat loss. Consequently, the population may have declined by 23% over the past three generations, with declines accelerating to 28% over three generations since 2016.
