Hello, I was hoping someone could help me with my cockatiel's constant screaming behavior. I let him out, we play we sing and whistle and dance and when I put him back in he immediately goes back to screaming even when I'm in the same room and he can see me. I cover him to make him stop and have even tried giving him treats to positively reinforce that when he stops he gets a treat. He's near a window he has food and water and I change his toys or at least rearrange them regularly. It's to a point now that I'm becoming bitter and resentful to him and have considered re-homing but I really don't want to do that. I've had him since he was a few months old and I've seen him thru some tough times. If anyone can help me I would appreciate it greatly!
