Population justification: The global population size has not been quantified, but the species is described as scarce to fairly common over much of its range, although locally numerous. The species is described as rare in Taman Negara, Malaysia (del Hoyo et al. 2007).

Trend justification: Precise data on population trends are lacking, but a moderately rapid and on-going decline is likely to be occurring as a result of habitat loss and degradation across its range.
