I am not a 100% sure what's going in be he started this 2 weeks ago. He dose it some times when sitting on his cage when the door of his cage is wide open even sometimes on me. He also opens his beak really fast like a clicking nose and pins his eyes but he never bites I am not sure if he is excited to see me or anything but he dose follow me around everywhere. If I leave the door open he will crawl down and walk down the hall way to find me sometimes. He is also very comical.
