This non-wooden mask is known among the Zombo as Nkoso and among the Nkanu as Kamatzala. Kamatzala can be translated as "lord with feathers." This mask is possibly developed from a gourd split in half, perhaps with a knitted fiber cap pulled over it. The eyes are usually made from gourd fragments and the feathers are inserted into the fiber netting. This mask is worn by an older initiate whose task is to accompany the neophytes when they leave the nkanda camp to go to the river or the village to steal food. Like a bird, this mask type is said to be capable of crossing borders (village, savanna, forest).
