An air-actuated wing assembly includes an assembly base having a generally elongated, flat, planar base panel a wing body carried by the base panel of the assembly base and at least one generally elongated, cupped half-wing portion extending from at least one side of the wing body. The half-wing portion is adapted to oscillate within a plane perpendicular to a plane of the base panel of the assembly base. An attachment mechanism carried by the wing body. The attachment mechanism is sized to attach to a decoy during use.
