This species is relatively tolerant of secondary and degraded forest habitats, and therefore remains relatively common and widespread across much of its range. However, it is likely to be declining moderately rapidly overall as a result of widespread deforestation for timber and conversion to agriculture, and is therefore considered Near Threatened.
