Singing bird box in rectangular silver case decorated with geometric patterns in the form of alternating chased and blue enamel frames. The top side is divided into two halves with the same ornament of frames and oval medallions, decorated with chased and white enamel elements in the form of arcs and straight segments. The left part is reclining on hinges, opening the automaton in a round window on the meshy field, which presents a frivolous scene. The automaton switch is located in the front side of the box. Hallmarks are on the inner automaton welt. The lid inner side is matt-finished, gilded. The medallion on the right side serves as a cover for the singing bird movement. The lid is automatically opened when the movement is activated; a miniature bird in the painted feathers appears from under it. It turns in place, flaps its wings, opens and closes the beak. The sound movement imitates bird’s chirping. At the end of the program, the bird hides under the openwork gilded lattice and the lid is lowered.

The sliding switch of the bird movement is on the front side of the box. Two keyholes – for winding the bird and the automaton, are in the box bottom.
