Population justification: The global population size has not been quantified, but the species is described as fairly common in Peninsular Malaysia and Borneo, uncommon in Thailand and rare in Way Kambas National Park, Sumatra (del Hoyo et al. 1999).

Trend justification: A  moderately rapid population decline is suspected to be occurring, owing to the continuing rapid loss of lowland forest habitats across the species's range.
