Population justification: The global population size has not been quantified, but this species is described as 'uncommon and patchily distributed' (Stotz et al. 1996). Due to its inconspicuousness and potentially nomadic behaviour, the species may only be temporarily patchy and thus more common than believed (Collar et al. 2020); the total population is unlikely to be small.

Trend justification: The population trend has not been quantified, but the species is feared to decline as a consequence of habitat loss and trapping for trade. Within the range, 6% of tree cover is lost over three generations (10.6 years; Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The species is restricted to humid forests, and therefore the rate of population decline may be higher than tree cover loss alone suggests, as forests are being degraded. The impact of trapping has not been quantified, but is described as low (Collar et al. 2020). Based on available evidence, the rate of population decline is unlikely to exceed 10% over three generations. Nevertheless, as the species is occurring in remote areas it may be more common and widespread than currently known, and consequently at lower risk than feared.
