Box with a singing bird in metal case in the shape of a book. A sliding switching lever with round head is on the side surface. The book cover and the back bone are decorated with chased ornament. The front and side surfaces resemble the pages. A keyhole and fixing screws' heads are on the bottom cover. An oval lid is in the upper side center. It opens automatically during the movement's operation; the lid external side is decorated with enamelled image of young men dressed in the clothes of the 8th century. When the movement is started, the lid hinges upwards, a miniature bird in painted feathers appears from under the openwork lattice. It turns at place, waves the wings, opens and closes the beak; the sound movement imitates bird’s chirping. When the movement stops, the bird hides and the lid goes down. The movement is made as per the scheme developed in Switzerland in 1895. The movement is cam-type, with one whistle and air bellows.
