Here is the story, and it will explain at least partially, the ceremonial use of turkey feathers.
Turkey feathers are much prized for ceremonial uses today. If you want to carry a little present to a Hopi friend, particularly an old man, or an old woman, save up a collection of especially nice looking turkey feathers. They will be put to ceremonial uses and bring blessings to their owners.
Here is at least one of the legends back of the idea, as collected by Stephen and reported by Mindeleff.[31] The chief of the water people speaks:
"In the long ago, the Snake, Horn, and Eagle people lived here (in Tusayan), but their corn grew only a span high, and when they sang for rain the cloud sent only a thin mist. My people then lived in the distant Palatkiwabi in the South. There was a very bad old man there, who, when he met anyone, would spit in his face, blow his nose upon him, and rub ordure upon him. He ravished the girls and did all manner of evil. (Note: Other variants of the legend say the young men were mischievously unkind and cruel to the old men, rather than that an old man was bad. H.G.L.) Baholikonga (big water serpent deity) got angry at this and turned the world upside down, and water spouted up through the kivas and through the fireplaces in the houses. The earth was rent in great chasms, and water covered everything except one narrow ridge of mud; and across this the serpent deity told all the people to travel. As they journeyed across, the feet of the bad slipped and they fell into the dark water, but the good, after many days, reached dry land. While the water, rising around the village, came higher, the old people got on the tops of the houses, for they thought they could not struggle across with the younger people. But Baholikonga clothed them with the skins of turkeys, and they spread out their wings and floated in the air just above the surface of the water, and in this way they got across. There were saved of our people, Water, Corn, Lizard, Horned Toad, Sand, two families of Rabbit, and Tobacco. The turkeys' tails dragged in the water—hence the white on the turkey tail now. Wearing these turkey skins is the reason why old people have dewlaps under the chin like a turkey; it is also the reason why old people use turkey feathers at the religious ceremonies."
Hough[32] says that in accord with the belief that the markings on the tail feathers were caused by the foam and slime of an ancient deluge, the feathers are prescribed for all pahos, since through their mythical association with water they have great power in bringing rain.
X. CEREMONIES FOR BIRTH, MARRIAGE, BURIAL
The story of the Hopi, who does every important thing in his life according to a traditional pattern and accompanied by appropriate religious ceremony, would not be complete without some account of birth, marriage, and burial. Not having seen these ceremonies, the writer offers the record of authoritative observers.
