There is a great story in First Nation US folklore about the origins of the crow. In the story, the crow was originally created in many beautiful colours and loved his colours deeply and how the light shone on them. But when he noticed his shadow, behind him, black as black, he became increasingly perturbed and started to peck at that shadow, to try and make it go away. Over time he became so obsessed with the shadow that he forgot about his colours entirely. All his attention was on the shadow and he pecked more and more… until the day that the shadow had had enough and pecked back, swallowing the crow up and leading to the black bird (with a shimmer of other colours) that we know today.
