The parrot looks in the mirror and gets angry at himself

Have you ever tried to put a mirror in a parrot’s cage? If you haven’t tried, then it’s worth a try. It gives a lot of emotions.
This parrot’s name is Charlie, he has recently become very passive. So I decided to hang a mirror in his cage. And our parrot is now playing with a mirror and trying to somehow remove it. Because he didn’t realize that it was his reflection. He already the third day sits in front of a mirror and tries to somehow remove this mirror.
