The Birdy Version of the Babble Ball (talking and sounds) hangs in the cage by a nickel plated chain.It is sensitive enough to be triggered by your Parrot moving near it or by movement within the cage.  The Babble Ball turns off automatically when finished and waits to be touched again.  Parrots absolutely love it!  Each ball has more than 20 different wisecracks or sounds, like "Rock 'n Roll Big Doggy", "Hey, What are you doing?", "Grrrrr!". "Sweet Puppy" and many more!  Babble Balls features durable high impact ABS construction, triple the sounds, improved sound quality and replaceable batteries!  Battery operated toys must not be dunked in water.  Therefore supervision is recommended while playing with these toys.  Please note that our current stock of the Birdy Version require a lot of force to make noise, and as such are only appropriate for very active Parrots such as Cockatoos or Caiques.
