German sterling singing bird box by Greisbaum circa 1935.
Fancy shaped case decorated overall with birds and foliage. Bird-shaped
slide to activate the mechanism. Loud and active bird with hummingbird feathers.
When the slide is activated the lid opens, the
brightly feathered bird pops up and moves from side to side moving its beak, wings
and tail in time with the chirps produced by the internal bellows and tuned pipe.
Then the bird drops back into the box and the lid closes automatically. The case detail is much better than in the photos.
