Does anyone here have a tiel with no personality? My tiel doesn't talk, he will whistle on occasion, he shrieks when I take him out of the cage...he will perch on top of the cage if I open the door. He doesn't particularly like scritches, but will tolerate them if he has pin feathers, otherwise, he just wants to be on my shoulder (but only cause it's the highest perch, not because he LIKES to be there, he would go to something higher in a heartbeat). He won't play on the play gym, but just stands there. He won't play with the toys in his cage, but will climb around the cage from time to time. I know he's not sick at this point, because he had actually gotten sick, has been on antibiotics, is all better now...that's just him. Is this a normal thing?
