Have you ever dealt with territorial cage behavior? This is a new hurdle for us. I was cleaning the cage out and I could tell he was fixated on me...however, he wasn't displaying his normal warnings. I continued to clean moving slow and talking to him. When I turned my back he flew and attacked my head. Luckily he did not bite BUT I was told thats what it looked like he was trying to do.
Today he still seems mad with me so I am keeping my distance and trying not to be an irritation to him.
