Population justification: The global population size has not been quantified, but the species is described as regular and common on the south and western coastal plains of peninsular Malaysia, locally common to uncommon in southern Thailand, fairly common in the Greater Sundas, uncommon to rare in the Nicobar Islands, and elsewhere local and uncommon to rare. (del Hoyo et al. 2005).

Trend justification:

The species is tentatively assessed as being in decline due to habitat loss per Tracewski et al. (2016) and high hunting pressure.
