I adopted a 2 year old male eclectus yesterday. He was friendly for the people I bought him from but he is being aggressive, biting and lunging with me. He will step up but then starts to attack your hand and fingers. He also lunges at you from inside the cage. He is eating well and talking too. How can I go about getting him to stop being aggressive? He will take treats from my hand. I want him to trust me so I can enjoy being around him. He doesn't seem the least bit afraid of anything or anyone. His wings are clipped.
