Hello conure-owners!

I have a friend who owns a sun-conure, who is about 3 years old. She says that the bird has become very possessive of her, and attacks anyone who comes to visit. I imagine it is probably regarding her as his partner and wants to protect her. It's become so bad now, she is thinking of giving the bird away.

As far as I know, she does not clip the wings of her bird and he is free in the house when she's home. Another problem she described was that the bird is screaming his head off if he's inside his cage, knowing that she is somewhere else in the house, and that he doesn't stop screaming until she lets him to her.

Does anyone have any tips and ideas on how to ease these problems?
