Population justification: The global population size has not been quantified, but the species is described as generally locally common. The population in Chu Yang Sin Nature Reserve in Vietnam is estimated to be 34,010 individuals (del Hoyo et al. 2007). This species is considered to have a medium dependency on forest habitat, and tree cover is estimated to have declined by 17.6% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, as a precautionary measure, it is tentatively suspected that this loss of cover may have led to a decline of between 1-19% in the species' population size over the same time frame.
