The Rufous-necked Hornbill (Aceros nipalensis) is a species of hornbill found in broadleaved forests at altitudes of 150–2,200 metres (490–7,200 ft) in Bhutan, north-eastern India, Burma, southern Yunnan, south-eastern Tibet, northern and western Thailand, northern Laos and northern Vietnam. Numbers have declined significantly due to habitat loss and hunting, and it has been entirely extirpated from Nepal.[1] It is estimated that there are now less than 10,000 adults remaining.[2] With a length of about 117 centimetres (46 in),[2] it is among the largest Bucerotine hornbills. The underparts, neck and head are rich rufous in the male, but black in the female.
