Population justification: The global population size has not been quantified, but the species is described as uncommon in Thailand and the lowlands of Borneo, and rare in Sumatra (Cheke et al. 2001).

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). However, this species is thought to have avoided rapid declines because it can adapt to secondary habitats, thus it is suspected to be experiencing a moderately rapid decline overall.
