"Native American culture believes in animalism. This means everything in the universe possesses souls or spirits. As well as humans, this applies to plants, animals, and other natural phenomena.
So, to Native Americans, birds are very special. When a feather falls from a bird, for many tribes it’s seen as a vessel of all the energy carried by that bird in its life.
This energy is then gifted to the appropriate recipient that is deserving of such an honor. As a feather falls at any given time, it’s distinguished as a gift from the sky bearing spiritual purpose for the recipient."
