My cockatiel loves to play on the top of his cage and whenever I'm home and I have him out all the time. I currently live in a studio apartment (so basically one big room) so I can watch him no matter what I am doing. Whenever it comes time for me to put him back into his cage for the night or because I need to leave my house. He gets mad at me and when I put my finger up he nips me to tell me no because he doesn't want to go back into his cage. Normally I wait about 30 seconds then try again and eventually he will get on my finger and let me put him up. One time I left my finger there even though he was nipping me and eventually he stepped up and let me put him in his cage. Is there any better way to handle this? he is completely fine with coming on my hand and interacting with me but he knows when he is about to go back in his cage and that is when he nips.
