The Thunderbird is a mythical Native American creature that rules over all natural activities. It represents divine dominion, protection, provision, strength, authority, and an unbreakable spirit. Plains Indians, as well as tribes in the Pacific Northwest and Northeast, use this cross-cultural emblem, albeit the meaning varies depending on the group.
The Thunderbird was seen to be a sign of war by some tribes, and the sound of thunder in the skies was thought to be a prophecy of tribal war triumph provided ritual dances and rites were completed. Others saw the Thunderbird as a solar creature that could govern the beginning of day and night by opening and closing its Sun-made eyes.
