Population justification: The global population size has not been quantified. It is described as rare in Myanmar; uncommon in Borneo, and common in Thailand, the Malay Peninsula and Sumatra (del Hoyo et al. 2008).
Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction.
