This craft is found in Patna, Saraikella, Hazaribagh, Murhu, Khunti (Ranchi) and Madhubani. Masks used in the Chhau dance represent the main item of production; mobile figures of different kinds of birds for decorative purposes are also made. Mask-making is a hereditary trade with some families, though even in these families only those who are dancers are allowed to make masks. Originally, the masks were made of wood, and then bamboo; today they are made of papier mache.
