I have a new parrotlet that I've had for about two and a half weeks now. He was born on January 14th so he's still very young. The problem I'm having is that, all of a sudden, he stopped making the pleasant little warbling noises that I so love. The only sound he makes now is a weird burst of two VERY loud chirps, and as of this morning he's taken to bobbing his head while making it. Originally he would do it a couple times and if I didn't come over to take him out he'd calm down and play with a toy, but this morning he did it for TWO HOURS STRAIGHT (no cruelty here, I just wanted to see if he would stop). When I go over and take him out, though, he doesn't stop. He'll keep tweeting and tweeting and bobbing his head, no matter what I do. He loves getting his head scratched, but he just fends me off if I go to do it. What does he want? What triggered this? He was a perfect little angel before a few days ago! 
Sorry this is so disjointed, I'm just so frustrated and upset by this change.
