Your bird is no ding dong, give him what he wants. With JW's Bell with Pendulot he will be one happy camper. Sounds of rapture will be ringing from your birds abode.
The Pendulot is not just a normal bell - the bell has a pendulum on top so when your bird hits the bead the bell will sound. Screws onto the cage, and is suitable for both parakeets and cockatiels.
