Population justification: The population size is unknown, but the species is described as generally scarce to uncommon, although locally common (del Hoyo et al. 2006).
Trend justification: Rates of forest loss in the Sundaic lowlands have been extremely rapid (Kalimantan lost nearly 25% of its evergreen forest during 1985-1997, and Sumatra lost almost 30% of its 1985 cover), because of a variety of factors, including the escalation of logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas, plus forest fires (particularly in 1997-1998). Because it tolerates degraded, fragmented and secondary habitats the species is thought to have avoided rapid declines.
