Resumo

A study was carried out to assess the food and foraging behaviour of Rufous-necked Hornbill Aceros nipalensis in Zhemgang district, Bhutan, through incidental observations of feeding activity obtained while walking along trails, focal sampling observations, and from analysis of regurgitated seeds around nesting sites. Thirty-three species of fruits and a few invertebrates were observed being eaten by Rufous-necked Hornbill. Feeding occurred mostly from small branches (<75 mm diameter, 58.5%) and within 4-28 m above the ground. Active feeding in the non-breeding season usually occurred between 06:00-12:00 hrs and 15:00-17:00 hrs. Evidences of grazing and felling of fruiting tree calls for reinforcing conservation management in Zhemgang district.
