Help, I came home this afternoon to find my 7-year-old green cheek on the ground of his cage, claws tightly curled around the bars, eyes open and beak biting into the bar. As if he'd had a seizure. I'm so sad. Angel was very violent, aggressive and strong. He couldn't sit with me without tearing into my flesh or ripping into my hands. His strength was unreal. He could do a hummingbird, flying in one place while looking right into my eyes. I had a very hard time trying to calm him but I did adore and care for Angel despite his violent behavior. I was told that some conures are mentally ill and that an avian expert could test him, which I never ended up doing. I had a feeling that there was something not right with him. Could birds be mentally ill? Was epilepsy a possibility for the aggression? I'm adding his last image that I took from underneath him. You can see how strong his hold was. It was so hard to unclasp his claws and beak from the bars.
