This forest-associated species is listed as Near Threatened because it is suspected to have experienced a moderately rapid decline owing to the extensive loss of lowland forests from large areas of the Sundaic lowlands. It is not considered more threatened because it can use secondary habitats and occurs in mid-elevation forest.
