The jealous husband parrot is a dynamic character because he comes to realize his flaws in their relationship. He realized that it was wrong not to talk to her about how he was feeling. He realized he was wrong for locking himself up (emotionally). As a parrot he desperately wants the chance to be able to communicate to her all the things he should have said to her as a man, but instead has to learn how to just let those feelings go.
This story has both internal and external conflict. The main character struggles with himself over his jealousy and insecurity of his wife being with other men and his pride which prevents him from opening his mouth about it. The external conflict, of course, is that as a parrot he can not communicate his feelings to his wife because of his limitations, which is very frustrating to him.
The setting is specific. It is set in Houston Texas in the home of the main character's wife from his life as a human. The story would be dramatically different if his wife hadn't been the one to buy him from the pet store. If, instead, a little old lady had purchased him, then the story would have more than likely been very flat. It would be missing the elements of frustration and irony brought about by him being in the presence of his wife and her new lovers.

We, as the reader, would not have had the same insight to the main character's struggles if it had been written in a third person or dramatic point of view.
