Give your birds a job; make them work for their food, and make it fun.
Shop here for a huge selection of forage feeders and toys.

Parrots should have a job. Not to pay for their room and board, but to keep them busy. Many of the behavior problems birds have are related to boredom. They are programmed to spend 70% of their day foraging for food. In a cage, they do not have to work for their calories and spend only seconds getting to the food dish, and the rest of their time wondering what to do. Foraging gives your bird a job. These toys will have your bird working for his treats in no time.
