Hunter's Specialties Squealing Hen Wild Turkey Call reproduces the sound a hen turkey makes during breeding, triggering an internal frenzied response from gobblers to seek and find the source of the sound. The revolutionary call is the first true new innovation in turkey calling in years. The call is easy to operate. Simply blow into the call while depressing the lever. This puts pressure on the internal Infinity Latex reed and the authentic high-pitched breeding hen sound is produced. Gobblers are driven to come in and check out the sound, which appeals to both breeding and territorial instincts. The Squealing Hen works great in areas that have seen a lot of hunting pressure, where birds have come extremely wary or conditioned to conventional calls.
