Justification of Red List category
This species has a pan-Sundaic distribution, occurring on the Thai-Malay Peninsula, Sumatra and Borneo. Here, lowland forest losses have been among the most rapid in the world (principally to make way for oil palm plantations), and this highly forest-dependent species is suspected of having declined rapidly in response. Over the last three generations (12 years: 2010-2022) it is suspected of having declined by more than 30%, and unless rates of deforestation slow rapidly, it will soon be confined to a fragmented network of protected areas. Accordingly, it is listed as Vulnerable.
