Population justification: The global population size has not been quantified, but the species is described as generally uncommon, although locally and seasonally common and very rare in Java (Gibbs et al. 2001).

Trend justification: The species is suspected to be declining at a moderately rapid rate, owing primarily to habitat loss and degradation, as well as hunting pressure.
