I came across an animated musical bird in a cage.  The birds head, beak
and tail feathers all move, plus it sings (not a tune).  It is in good
condition.  The only identification is "KEN_D" stamped in a square,
along with a stamp of a small bird on a branch on top what appears to
be mountains, with the letters K. and G. on either side of the bird.
It is made in Germany.  The works are mostly brass.

Can you tell me anything about it or tell me of someone who can?

Thank You
