Population justification: The global population size has not been quantified. The species is reported to be widespread, but occurring at low densities (del Hoyo et al. 2001). In prime habitat, it can be locally common (Poonswad et al. 2013).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction (del Hoyo et al. 2001). An analysis of deforestation between 2000 and 2012 estimated forest loss within the species's range at 26.9% over three generations (29 years) (Tracewski et al. 2016). While the species's apparent tolerance of some habitat degradation might buffer the detrimental effects of deforestation to a certain degree, it is also threatened by hunting. Thus, the rate of decline is placed in the band 20-29% over three generations. Assuming the recent rate of decline remains constant, the species is projected to decline by 20-29% over the next three generations.
