Thunderbird

The thunderbird is a legendary creature in certain North American indigenous peoples' history and culture. It is considered a supernatural being of power and strength.
The thunderbird is said to create thunder by flapping its wings, and lightning by flashing its eyes.
Thunderbirds in this tradition may be depicted as a spread-eagled bird (wings horizontal head in profile), but also quite commonly with the head facing forward, thus presenting an X-shaped appearance overall.
