Population justification: The global population size has not been quantified, but the species is described as 'fairly common' (Stotz et al. 1996).
Trend justification: The species is assessed as being in decline as a consequence of the loss, fragmentation and degradation of its habitat and the potential threat of hunting and trapping. Tree cover within the range has been lost at a rate of 16% over the past three generations (17.1 years; Global Forest Watch 2021, using Hansen et al.  data and methods disclosed therein). As the species is restricted to undisturbed forests and only tolerates low levels of habitat conversion (Collar et al. 2020), population declines may be steeper than the rate of tree cover loss suggests. To account for the impact of disturbance and forest degradation, it is here tentatively assumed that the rate of total habitat loss exceeds the rate of tree cover loss by half, i.e. 8%, so that an overall 24% of habitat was lost over the past three generations. The potential impact of hunting and trapping has not been quantified, but in the absence of exact data it is tentatively assumed that this threat adds another 5% to the rate of decline. Based on these calculations, it is suspected that the population declined by 29% over the past three generations. Since 2016, the rate of tree cover loss has been increasing to a rate equivalent to 22% over three generations (Global Forest Watch 2021, using Hansen et al.  data and methods disclosed therein). Under the assumption that disturbance and degradation add a relative half to this rate, i.e. 11%, and that hunting and trapping account for an additional 5%, the population may now be declining by 38% over three generations into the future.
