The rufous-necked hornbill (Aceros nipalensis) is a species of hornbill in Bhutan, northeastern India, especially in Arunachal Pradesh, Indian Subcontinent and Southeast Asia. It is locally extinct in Nepal due to hunting and significant loss of habitat.[1] There are less than 10,000 adults left in the wild.[3] With a length of about 117 cm (46 in),[3] it is among the largest Bucerotine hornbills. The underparts, neck and head are pigmented as a rich rufous in the male, but black in the female.
