My tiel is like this, too - wants me in the room with him or at least where he can see me. I always tell him I'll be right back - it does no good! Sometimes it'll help if I talk to him from another room, sometimes not. If I'm going out of the house, I leave music on for him, and I do think that helps him for long periods of no mama!! Otherwise, he continues his flock call for me! Can't stop it.
