I can’t tell you how many times I have been asked a question like the following:
How can I stop my parrot screaming?
How can I stop my parrot biting?
How can I stop my parrot (insert unwanted behavior)?
I am sure you see the pattern here; asking this kind of questions doesn’t lead to any kind of resolution, only frustration. Simply trying to reduce unwanted behavior somehow misses a couple of important points, not the least of which is that, typically, focusing on reducing behavior leads to the use of aversives, things the bird will work to avoid. Behavior science tells us that such techniques do not lead to a good working partnership with our birds. They in fact work against building trust.
The way to avoid this situation is through a different type of question, one that asks what you want the bird to do. For example if you have a bird that is biting your hands when you try to move him in and out of his cage ask yourself, what do I want him to do? Typically what is wanted is for the bird to step onto the hand without biting when requested. This is a behavior that can be built with patience and a large helping of positive reinforcement. Avoiding force and coercion to get the bird onto your hand gives the power of choice to the bird and through many repetitions of the behavior also builds the bird’s trust in you the trainer and the chances are the biting will be reduced.
My point here is not to teach how to train a particular behavior but to encourage you to ask questions that lead you to using the most positive least intrusive strategies for training. It is through the use of these strategies that you will build a trusting relationship with your bird.
