Fritz (Jardine's Parrot. 2 years old) has some cage aggression issues. He will try to lunge sometimes when you are taking his water or food dishes out, or trying to re-arrange his cage toys. What can I do to discourage this activity, and make him less aggressive. It does not always happen, but it happens enough that taking out his water dish can become a mission (and in typical Jardine's manner, he likes to make pellet soup, so it must be changed often!)
Any help is greatly appreciated.
I will answer any questions that will help you to help me
