"The circle represents a nest and is drawn by the toe, because we are imitating the bird making its nest.

If you go on a high hill and look around, you will see the sky touching the earth on every side and within this circular enclosure the people live.  So the circles we have made are not only nests, but they also represent the circle the Great Spirit has made for the dwelling place of all people."
