In Oklahoma when I grew up it was always 'KY-oat' except in the cartoons in which the critter after Roadrunner was 'Wile E kiYOtee' which we thought was comical. I did not hear 'ky-OH-tee' except from visitors until I moved to Connecticut.
Don Edwards recorded 'Coyotes' on "Going Back to Texas" and "Best of Don Edwards" about an old cowboy, lamenting the changes of the West he knew.
Now the longhorns are gone,
And the drovers are gone. . .
And the lion is gone,
And the red wolf is gone. . .
and eventually the cowboy disappears without a word, but that night
One more coyote was heard. It has a very haunting chorus that rather yodels after the fashion of the coyote call. Naturally he sings it 'KI-oat."
