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.Features: Single reedLaminated barrel
