An attractive singing bird box in beautifully worked mother of pearl to the lid and all four sides with gilt bronze frame. Excellent quality, probably German, early 20th century. When the operating lever is pressed to the right the lid opens and the brightly coloured bird pops up through the gilt bronze pierced grille and begins his performance. He sings, turns from left to right, flaps his wings and opens and shuts his beak. After a few seconds he finishes his performance, disapears down throught he grille and the lid closes after him ready for his next performance. 4.5 inches wide by 3 inches deep by 1.75 inches high ( 11.25 cms by 7.5 cms by 4.375 cms).
