Population justification: The global population size has not been quantified, but the species is described as scarce to fairly common over much of its large Sundaic range (Wells 2007, Mann 2008, Eaton et al. 2016). It is therefore not considered likely to approach population size thresholds (<10,000 mature individuals) for listing as threatened.

Trend justification: Estimations on rates of population trend in this species are lacking. However, given its forest dependence, an ongoing rapid decline is suspected on the basis of extensive lowland forest loss throughout the Greater Sundas. Global Forest Watch (2022), using data from Hansen et al. (2013) and methods disclosed therein, indicates that forest loss of 24–28% has occurred over the past three generations, and these rates are not anticipated to cease or slow in the future. The species is therefore suspected to being undergoing a decline near-equal to that of forest loss: population declines of 20–29% are therefore suspected to have occurred over the past three generations, and are predicted to continue in the future.
