Population justification: The global population is suspected to number 50,000-499,999 mature individuals (Partners in Flight 2022).

Trend justification: The species has become locally extinct in parts of its range, likely as a consequence of extensive deforestation (Collar et al. 2020). It is moreover captured for trade, albeit in very low numbers (Collar et al. 2020).
Tree cover within the range is lost at a rate of 16% over three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Apart from forests, the species also occurs in plantations, woodland, savanna, agricultural areas and open habitat (Collar et al. 2020); consequently, population declines may be slower than the rate of tree cover loss suggests. The impact of trapping on the population size has not been quantified, but it assumed to be low. Tentatively, population declines are here placed in the band 1-19% over three generations.
