The oak is stand. The acrylic paint is black, red, green, and orange.

The paint is red. The wool cloth is red.

The paint is green, black, black, red, orange, and dark red.

Spirit of the Ancestors-The dancer cocks the Kolus head to one side, slowly sweeping its piercing eye across the house, then tilts and reverses his swing as the song describes the Kolus, calling it Screecher Mask. - Bill Holm

Throughout the masking area of the Northwest Coast, the dramatic effect of opening jaws and other moving parts on masks was recognized. Of all the tribes using masks, however, the Kwakwaka'wakw carried articulation to its highest development. This small thunderbird forehead mask uses two variations on the theme. The lower mandible is hinged to allow it to open and close, and the crest of wooden feathers between the ears can be spread like a fan or dropped back to lie flat on the head. Strings control movement of these parts. (Holm, Crooked Beak of Heaven, 1972)
