Yes. They have an attitude like a teenage girl. Around 6 months, Echo was really pissy. Now, at a year old, he comes out and hangs out with me almost daily. But I still have to move slowly and carefully. I have been bit, and it HURT! I was surprised by the jaw power he had, and it wasn't even when he was mad. He accidentally got me when I was trying to hand feed. I have had parrots who didnt bite that bad! But, as I said, he was quite pissy today, so he is back in his cage chillin now.
