Very rare vintage chirping bird in cage

One of a kind , I researched and can't find another one like this. It is battery operated, with wiring on the outside of the cage to connect to the swinging perch. When the perch moves it connects to the wire to make the chirping. It chirps about 5 times and stops. I wish I could do a video with sound because it's really cool! I really have not seen one made like this one. I'm sure it's VERY valuable to the right collecter because of the way it is made. I honestly don't know what the cage is made out of, but I don't think it is metal. The holes at the bottom is for the speaker, or sound. Nothing missing there. The bird is made out of felt and the feathers, not sure because they look and feel very real! The bottom base is plastic. Alot of fun I hate to give up, but I'm sure someone would love this one for their collection.
