Actually, in other archaelogical records there are similar writings, but a different bird. So doesn't really mean anything deeper.
Canadian Indian Tradition
Neben Manito rolled into the sea, and cried, "Revenge! Revenge!" Then all the assembled monsters of the deep rushed headlong after the slayer of their king. The prophet fled in consternation before the outraged creatures that hurled after him mountains of water, which swept down the forests like grass before the whirlwind. He continued to flee before the raging flood, but could find no dry land. In sore despair he then called upon the God of Heaven to save him, when there appeared before him a great canoe, in which were pairs of all kinds of land-beasts and birds, being rowed by a most beautiful maiden, who let down a rope and drew him up into the boat.
The flood raged on; but, though mountains of water were continually being hurled after the prophet, he was safe. When he had floated on the water many days, he ordered Aw-milk (the beaver) to dive down and, if he could reach the bottom, to bring up some earth. Down the latter plunged, but in a few minutes came floating to the surface lifeless. The prophet pulled him into the boat, blew into his mouth, and he became alive again. He then said to Waw-jashk (the musk-rat), "You are the best diver among all the animal creation. Go down to the bottom and bring me up some earth, out of which I will create a new world; for we cannot much longer live on the face of the deep."
Down plunged the musk-rat; but, like the beaver, he, too, soon came to the surface lifeless, and was drawn into the boat, whereupon the prophet blew into his mouth, and he became alive again. In his paw, however, was found a small quantity of earth, which the prophet rolled into a small ball, and tied to the neck of Ka-ke-gi (the raven), saying, "Go thou, and fly to and fro over the surface of the deep, that dry land may appear." The raven did so; the waters rolled away; the world resumed its former shape; and, in course of time, the maiden and prophet were united and repeopled the world.
Masai (East Africa):
Tumbainot, a righteous man, had a wife named Naipande and three sons, Oshomo, Bartimaro, and Barmao. When his brother Lengerni died, Tumbainot, according to custom, married the widow Nahaba-logunja, who bore him three more sons, but they argued about her refusal to give him a drink of milk in the evening, and she set up her own homestead. The world was heavily populated in those days, but the people were sinful and not mindful of God. However, they refrained from murder, until at last a man named Nambija hit another named Suage on the head. At this, God resolved to destroy mankind, except Tumbainot found grace in His eyes.
God commanded Tumbainot to build an ark of wood and enter it with his two wives, six sons and their wives, and some of animals of every sort. When they were all aboard and provisioned, God caused a great long rain which caused a flood, and all other men and beasts drowned. The ark drifted for a long time, and provisions began to run low. The rain finally stopped, and Tumbainot let loose a dove to ascertain the state of the flood. The dove returned tired, so Tumbainot knew it had found no place to rest. Several days later, he loosed a vulture, but first he attached an arrow to one of its tail feathers so that, if the bird landed, the arrow would hook on something and be lost. The vulture returned that evening without the arrow, so Tumbainot reasoned that it must have landed on carrion, and that the flood was receding.
When the water ran away, the ark grounded on the steppe, and its occupants disembarked. Tumbainot saw four rainbows, one in each quarter of the sky, signifying that God's wrath was over.
agreed !! no salvation outside of Christ
