During the winter months the Indians of the Pacific Northwest coast have special ceremonies. With the Kwakiutl, the Nootka and the Bella Coola these are the winter dances. They involve singing and dancing with the performers wearing masks representing the spirits and animals featuring in their lives. The Indians believe that in the winter supernatural beings and spirits visit the villages. The Cannibal spirit is the most feared and he lives then in a house in the north. They also use the depictions of animals and spirits as symbols of their clans, tribe and family.
