- a piston that slides into a cylinder to inject air into the whistle in order to imitate the singing of a bird,
- wherein said device comprises:
- a compressed air reservoir between said piston and said whistle;
- an excess pressure valve, which opens automatically as soon as the pressure difference between the interior and the exterior of the compressed air reservoir exceeds a threshold;
