I combined this with another publication by Don Parks of Cincinnati Animal Productions to create this course about 10 years ago. Can this course be used to train smaller birds. The principles you will learn in this course can be applied to the training of any animal or bird. But the specific behaviors you learn to train in this course are designed to train birds ranging in size from conures to large macaws and cockatoos. They are smart and always are a surprise hit of any show.
People expect large birds to be intelligent.
They are flabbergasted when they see a cockatiel take dimes and put them into a small bank. Because of costs, most people don't train a cockatiel. But you can do so if you want to train. And remember, you can use all the techniques you learn to train any bird you own at a later time. I see them advertised.
