Hornbill, the relatively lesser-known sister publication to the much widely known Journal of the Bombay Natural History Society (JBNHS) is a quarterly magazine being published by BNHS since 1976. The magazine brought together popular articles by the who's who of conservation and natural history giants of India including Salim Ali, Zafar Futehally, Humayun Abdulali, J.C. Daniels, M. Krishnan, AJT Johnsingh, Asad Rahmani, and almost all other notable names in the field of natural history and conservation in India (and especially those associated with BNHS over 75 years) during the course of its publication. The magazine is currently (i.e. in 2022) in its 46th year of publication and continues to bring studies and observations in natural history to the masses.

The Archives of Contemporary India (ACI) has digitised all issues of Hornbill from 1976 to 2016 (digital issues of the magazine are available with BNHS from 2017 onwards) from Divyabhanusinh Collection housed in WWF-India library. The digitisation of this magazine has thus saved an invaluable repository of natural history and conservation writing from being lost or destroyed by vagaries of time. Through the process, ACI has also created the only institutional source for scholars to access all the digital archives of this magazine thus forming an invaluable resource material for scholars and researchers studying nature, ecology and environment.
