Inspired by a 1908 photo taken by Edward Curtis. The Hidatsa, a part of the Sioux tribe, are well known for their ability to trap eagles. Their feathers were used to make war bonnets or “maicu-mapuka” (eagle hats). Many times only a few tail feathers were plucked and the eagle was released. The eagle is considered a mediator between people and the Creator. Eagle feathers are considered sacred because they belong to a sacred bird.
