It is found in southern China and northern Vietnam. Its natural habitat is subtropical or tropical moist lowland forests; it primarily resides in the canopy.
It is an omnivore. Formerly, some authorities classified the chestnut bulbul in the genus Hypsipetes and also as a subspecies of the ashy bulbul. Wikipedia →
