Population justification: The population size has not been quantified, but the species is thought to be rare to scarce throughout its range (Bierregaard et al. 2020).
Trend justification: The population trend has not been assessed directly, but the species is suspected to be declining as a consequence of the loss and degradation of its forest habitat and potentially localised hunting. Within the range, tree cover is lost at a rate of 11% over three generations (24 years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Even though it is occasionally observed in degraded habitats, near forest edge and in dense woodland, the species appears to require large tracts of forests and as such, population declines are likely faster than tree cover loss alone. Precautionarily, it is assumed that forest degradation increases the rate of habitat loss by half, so that the combined impacts of tree cover loss and degradation would cause a total of c.17% habitat loss over three generations. The impact of hunting on the population size has not been quantified, but it is tentatively assumed that this threat alone causes a population decline of c.5% over three generations. The rate of population decline is therefore placed in the band 20-29% over three generations, but this value requires confirmation.
