A bird-calling device which is adapted to be securely held in the mouth of a person for use in imitating sounds made by birds-especially wild turkeys. A rigid base is adapted to fit within the roof of a person's mouth, somewhat in the manner of a partial denture plate. The rigid base is uniquely fitted to each person, and it has protruding wires which are located and sized so as to anchor the base to one or more teeth. A U-shaped recess in the rigid base is sized to tightly hold a removable diaphragm assembly. The diaphragm in the assembly is positioned so that it is exposed to selective contact by the user's tongue, preferably in a region well back of the tip of the tongue. When the user expells air past the diaphragm, an imitation bird sound may be produced; and the sound may be varied by changing the position of the user's tongue with respect to the diaphragm.
