This call imitates the whimpering cries of a female coyote during the preliminary stages of the breeding process. Randy captured the rare event on video as seen on the “Mastering The Art® of Predator Calling” DVD. This sound attracts all coyotes from young pups to adults, not just the dominate males. Coyotes are a very curious animal. There have even been fox and bobcats visit this sound. The sound actually sounds like a loud bird tweet-tweet-tweet, ect. Coyotes could relate this sound to breeding, ki-yi’s or even a mouse or rodent.
