Great hornbill (Buceros bicornis) which belongs to Bucerotidae family is a big bird found in the Indian subcontinent and Southeast Asia. It is recorded as Endangered in Red data book of Nepal, Vulnerable in IUCN Red list, Appendix I of CITIES and protected species in NPWC Act 1973. It requires large and dense forest for feeding, roosting and nesting. Principally, the species is frugivorous, often an opportunist and prey on reptiles, small mammalian and avian species. In Nepal, it is distributed in the pocket areas of Chitwan, Bardia, Parsa districts and occasionally in Shuklaphanta National Park and patchily distributed outside protected areas. Despite being ecologically important species and severely threatened, the species is poorly studied and documented in Nepal. Thus, this paper aimed to review different published secondary sources to explore the conservation evidences of Great hornbill in Nepal. Numbers of papers are utilized to filter the results and interpret the information regarding its status, distribution and threats. We found that the population status of Great hornbill is in declining trend and the present population is expected to be on the range of 80-150 in Nepal. Habitats are threatened and endangered due to conventional hunting, deforestation, habitat loss and forest modifications at alarming rate. This study has suggested some action with ground level evidence in favor of Giant Hornbill to conserve this beautiful creature in wild.
