Abstract: A whistle-type game call for reproducing sounds made by certain whistling animals, such as ducks or other waterfowl, without manipulating (e.g., rolling, vibrating, fluttering, etc.) the tongue. The whistle may include a sound chamber with one or more protruding ridges to space a free-floating tubular member contained by the sound chamber from an internal surface of the sound chamber. The spacing between the free-floating tube and the internal surface of the sound chamber prevents the free-flowing tubular member from sticking to the internal surface of the sound chamber due to accumulations of water, dirt, saliva, or any other foreign substances. The whistle may also include a hole for a lanyard to more conveniently carry the game call. The game call may be constructed from two halves, one of the halves having a ridge track and the other having a recess receptive of the ridge track to ensure proper alignment of the two halves.

Abstract: A slate-type game call includes a flange extending downwardly below the bottom wall of the pot portion of the call. The flange creates a unique sound chamber. One or more apertures may be provided around the flange to assist in projecting sounds from the sound chamber when the call is secured to a support surface. The flange may further include a pair of slots through which a fastening strap can be inserted to secure the call to a person's limb or hunting implement. Relatively narrow channels leading to the strap slots may be formed in the flange to allow the game call to be quickly connected and disconnected from the fastening strap. The configuration of the flange in combination with the flexible fastening strap allows the game call to be pivoted relative to a support surface to which the game call is secured to project and direct sounds from the sound chamber.
