An improved sound toy, essentially characterized by being constituted by the corporeal figure representative of a bird, permanently attached to a lower tubular support that has one of its ends open to allow the insufflation of air, whose fluid moves along a conduit which is eventually sealed by a counterweight plane attached to a lever, which is capable of turning on an upper point, said lever being provided on changeable centers of gravity, whose upper terminal corresponds to the lower part of the peak of the imitation bird, determining its closing and opening movement in collaboration with the air projected by the means described.
