I have a 2-year-old male turquoise green cheeks conure that I’ve had for about a week, who is very friendly and likes to be with me anytime he’s out of his cage (2-4 hours a day), and likes me to pet and scritch his head. The problem is he’s started to constantly try to pinch my skin even through clothes. I’ve taken to wearing a long-sleeved canvas shirt over layers when he’s out and just ignore it. He steps up on my finger just fine and is not otherwise aggressive. How do I deal with that to get him to stop?
