Most parrots have a strange instinctual desire to insert objects inside other objects - it is a natural game to them. The goal here is to teach them to do it on COMMAND. The Teach Box is rewarding for the bird because it is easy to do and builds on natural behaviors. This set includes discs and coins. As you will notice, the game presents openings on top and has no bottom. Teach your parrot colors, shapes, and even counting with this durable and bird-safe learning tool. Ideal for curious Cocktoos! Sized for medium parrots such as Amazons, African Greys, Cockatoos, Pionus, Eclectus, etc.
