Among the five species of hornbills that occur in north-eastern India, the least studied are the endangered Rufous-necked Hornbill Aceros nipalensis, and the Brown Hornbill Anorrhinus austeni, which has a restricted distribution in India. Based on field surveys conducted in Namdapha National Park, and several forest divisions in eastern Arunachal Pradesh, during 1996–1999 and 2002–2004, I present information on their distribution and relative abundance. I also present some information on diet, flock sizes, canopy levels used, breeding biology, and nesting records for both these species.
