Takara Plastic Singing Birds
These animated wild birds sing and move their heads, beaks and tails like real birds. These electronic birds have tiny motion sensors in their breasts that react to a change in light through motion, causing the birds to break into their natural bird song.
The design for each lightweight electronic bird was hand carved. In Japan, bird owners actually house them with their real birds to keep them company.
Prices range from $4.17 to $16.87
