A reflective decoy device for hunting wild turkey employs a glass mirror and strutted gobbler feathers. The turkey decoy device is attached to a hunting weapon, such as a shotgun or compound bow, with its mirror element substantially vertical to the line of fire. A partially transparent, partially reflective one-way mirror, half-silvered sight is incorporated in the mirror decoy for aiming the mirror perpendicular to the line of sight. This device create an illusion of a 3D decoy which may be used as a big game decoy for various animals such as antelope, mule deer, white tail, and elk.
