Population justification: The global population size has not been quantified, but the species is reported to be fairly common to common in most of its range (del Hoyo et al. 2002).

Trend justification: Rates of forest loss between 2000 and 2010 have been estimated at 23.7% for Sumatra and 8.2% for Peninsular Malaysia (Miettinen et al. 2011), and data in Margono et al. (2012) suggest that primary forest on Sumatra was lost at a rate of c.36% over 20 years. Given the estimated three-generation trend period of c.26 years for this species, it is thought likely that it is undergoing moderately rapid population declines (approaching 30% over three generations) despite its tolerance of habitat modification.
