Coyotes like anything that sounds like it is about to give up the ghost. That basic quick cries of desperation, pain, and terror are the same. Think of it in the terms that all distress sound are alike in their basic "Wha Wha"... the only thing that differs will be the pitch and tone. I'm not sure that a coyote thinks, "...hay I hear a woodpecker!" I think they just know something is dying. /ubbthreads/images/graemlins/grinning-smiley-003.gif
