Koya tribe in Andhra Pradesh's Papikonda hill range move from traditional Indian Bison horns to palm leaves to craft their flute, Permakore, as a gesture of conservation. Koyas use Permakore to call villagers to hunt, celebrate catch, and mark the start of the agricultural season. The palm tree is deeply rooted in Koya culture, and the craft of making a musical instrument from palm leaves is not well known outside the tribe. Koyas hope for identity cards to settle conflict with wildlife authorities over possession of bison horns.
