I havn't really learned all his noises yet. He chirps with the music, and gets louder as the music does, but he also does this screech that I can hear from the livingroom. I thought that was him not liking it, but he does it even when the music isn't on sometimes. he'll sit on the perch, switch his footing back and forth, chirp loud, then make that short screech maybe 3 times, then chirp some more.
