This festival focuses on wildlife conservation, with a particular emphasis on hornbills.
Four species of the birds - Wreathed, Great Indian, Oriental Pied and the endangered Rufous-necked - are found in the Pakke Tiger Reserve (PTR) of Arunachal Pradesh.
The area is also home to the Nyishi, the largest tribal group in Arunachal Pradesh.
The festival aims to recognise the role played by the Nyishi in conserving hornbills in PTR.
