Traditional Iroquois headdresses are called "kastówes”. The word kastówe means “feathers hanging.” Feathers are fastened to the top of the hat and the arrangement of the eagle feather identifies the Nation of the wearer.
Mohawk: three feathers up
Oneida: two up and one down
Onondaga: one up and one down
Cayuga: one up
Seneca: one down and it twirls as they walked
Tuscarora: no eagle feathers
Chiefs would wear a kastówe with deer antlers.
The frame-work consists of a band of black ash splints adjusted around the head with a cross-band arching over the top. The band is covered with tanned skin, red or blue broadcloth, velvet or fancy handchief and then decorated with either quillwork, beads, or a silver band.
