Super Bird Creations Bird Toys are known for using only bird safe parts that birds can't resist. The Rainbow Bridge, Jr. Bird Toy hangs from the top of the cage from two quick-links to make a bridge or a swing for your bird to play on. Your small to medium sized pet bird will love chipping away at the dozens of soft pine slats, cubes and balls. Nylon chain and Polly Rope make this bird toy an all time favorite. The Rainbow Bridge Bird Toy is available in three sizes.
