Pito con dispositivo recreativo, que se caracteriza porque sobre la caña del pito, con sus correspondientes orificios de vibración insuflado, se dispone cruzado el cuerpo hueco de un ave, provisto de alas, montadas sobre un eje que cruza el cuerpo hueco y cuyas alas constituyen planos pero desfasados casi 90º entre si, quedando debajo de estas alas, y practicado en la misma generatriz de la capa del pito sendos agujeros pon donde, al a salir el aire que se insufla, incide sobre las alas a las que hace girar, agitándose así mismo la cola del ave que descansa sobre el eje de las alas por su extremo no visto cola que sale al exterior aumentando con su movimiento el efecto visual y recreativo
