During the flood birds or animals escape to some place (mountain, tree, boat, sky). Tips of their tails or other body parts get covered with water or foam and acquire their present color and form
Birds or humans later changed to birds are sent to explore the earth (is it dry, are any survivals, to investigate why smoke rises to the sky, etc.) or to bring some soil to make the land that would be good for living

A group of persons decide to go to the end of the world to meet the Sun or other supreme god. One (or several) of them perish on their way, some reach destination, at least one returns home using the shorter way than the one they have took before
