Nyishi tribe is found mainly in

The Nyishi tribe is the largest ethnic group in the state of Arunachal Pradesh, located in northeastern India [3]. They are primarily concentrated in districts such as Kra Daadi, East Kameng, Kurung Kumey, and Lower Subansiri [1]. Traditionally, the Nyishi people practice 'jhum' or shifting cultivation and speak the Nishi language, which belongs to the Tani branch of the Sino-Tibetan family [3]. In their cultural belief system, they hold the tiger as a sacred animal. Historically referred to as 'Dafla' by outsiders, the term Nyishi translates to 'human being' [3]. While other regions like the Andaman and Nicobar Islands are home to tribes like the Jarawas and Nicobarese, and the Nilgiris are inhabited by the Toda tribe, the Nyishi are distinctively indigenous to the mountainous terrain of Arunachal Pradesh [4].
