According to Cherokee legends, in the old days, Grouse had a good voice and Turkey had none. Therefore Turkey asked Grouse to teach him. But Grouse wanted pay, so Turkey promised to give him some feathers for a collar. That is how the Grouse got his collar of turkey feathers.
So the Grouse began to teach Turkey. At last Grouse said, “Now you must try your voice. You must halloo.”
Turkey said, “Yes.”
Grouse said, “I’ll stand on this hollow log, and when I tap on it, you must halloo as loudly as you can.”
So Grouse climbed upon a log, ready to tap on it, but when he did so, Turkey became so excited that when he opened his mouth, he only said, “Gobble, gobble, gobble!”
That is why the Turkey gobbles whenever he hears a noise.
