Population justification: The global population size has not been quantified, but the species is described as not common (Cleere 1998).

Trend justification: Forest destruction in the Sundaic lowlands of Indonesia has been extensive, and the situation is little different in Thailand and Malaysia, but this species's ability to persist in regenerating and second growth habitats suggests it is probably not suffering more than a moderately rapid decline.
