The Wing Bone Yelper™ was probably one of the first turkey calls used by Native American Indians to call turkeys. The Wing Bone Yelper™ consisted of the three bones of a turkey’s wing, but we have perfected the call with modern technology. There is no doubt, for those who master this call; it becomes one of their secret weapons. It produces soft to loud, unique yelps and clucks. It also features a “kisser” button which assures perfect mouth positioning every time. You’ll have fun with this one.
