>>73482860In the Rainbow Crow story, the world was plunged into a freezing cold because the creator deity thought snow into existence. When the animals discussed what to do, they decided to send the Rainbow Crow to heaven to tell god to unmake snow. Back then the Rainbow Crow’s the most beautiful bird with feathers of rainbow and the best singing voice, which it used to get god’s attention. While god’s unwilling to unmake snow (since it would kill the snow spirit) god gave the fire from the Sun to the crow and told it to bring it back to ward off the cold. During the journey back home the smoke from the fire charred the Rainbow Crow’s feather and destroyed its voice, but it managed to bring fire back and save the world. That’s why crows now have black feather and a coarse voice, but some of the original plumage remained as its iridescence
It’s also probably a story some white people made up and sold it as a native folklore
