Monday zorro attacked my friend aggressively. Drew blood on her hand twice. Event flew across the room n bite her. So i finally had to cage him n even then he tried get her through the bars. She was like why didn't you warn me. I was like he's never been aggressive b4.

Sometimes birds just take a dislike to someone...
Maybe a colour she wore, or perfume... could be for any reason.... at least now, you know, and will be prepared for anyone else...

Maybe he was trying to protect you.

Look into the breeding cycle of caiques to see if he's old enough to be hormonal, because it sounds like this might be the problem. He might see her as an intruder into his territory, or someone who's getting too friendly with his "mate" (you). This is the way that a lot of Amazon parrots and cockatoos behave when they're hormonal.

According to most people they hit sexual maturity around age of 2 to 3 yrs of age.

Tj thinks he was being territorial, becuse they werent interduced outside my bedroom. He might consider my room his. Which makes since because ive read caiques can be extremely territorial. 2 days later Patrick had friend over that wanted to meet zorro, so i took him into living room. And nothing happened just sat there n let the guy pet him.

That's probably what it was. Some species are territorial all the time, not just when they're hormonal.

Yea think caiques are boy was i stressed after that.
