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.
