Comanche

In the olden times, a hunter once shot at a large bird which was flying above him. It fell to the ground. It was so large he was afraid to go to it alone, so he went back to the camp for others.

When they came back to the place where the bird had been shot, thunder was rolling through the ravine. Flashes of lightning showed the place where the bird lay. They came nearer. Then the lightning flashed so that they could not see the bird. One flash killed a hunter.

The other Indians fled back to the camp. They knew it was the Thunder Bird.

Once the Thunder Bird, in the days of the grandfathers, came down to the ground and alighted there. You may know that is so, because the grass remains burned off a large space, and the outlines are those of a large bird with outspread wings.
