Singing bird box is in metal case, decorated with chased patterns and artistic enamel. The case top and sides are decorated with chased patterns combined with engraving, painted and champlevé enamel. Enamel image of  various birds' choir conducted by a small bird is the top. Miniature spring driven  movement is mounted inside the box. The lever in the shape of a bird with spread wings is on the case front side. Oval lid that covers the bird nest is in the top center.
When the movement is activated, the lid leans back and a bird in colorful feathers appears from under it. The bird begins to turn from side to side, flaps its wings, opens and closes its beak. Bird chirping is heard. In few seconds the bird stops and hides. The lid goes down. The device is built according to the scheme developed as early as 1795 in Switzerland. Cam mechanism with one whistle and pneumatic bellow comprise the movement.
