Abstract
A game call apparatus requires an airflow across a sound-producing reed, which may be produced by a bellows, to create a variety of sounds that simulate the sounds of wildlife animals. The game call apparatus may include, in one embodiment, a pressure point structure which engages the sound-producing reed at a reed contact location. The pressure point structure can be manually manipulated to move the pressure point structure along the reed and change the reed contact location so that the sound-producing reed gradually changes the sounds produced by the game call apparatus. The bellows may include an aperture which must be covered when the game call is used. When the game call is not being purposely used, the aperture allows air to escape when the bellows are inadvertently collapsed to prevent the game call from sounding.
