We all have birds and birds sing so let's hear a recording of your bird happy and singing away. I'll start with an mp3 I put on youtube of my cockateil, Hades, "chanting" in the afternoon. I love his confused look when I play this file back for him. Then he screeches and looks around to see who is chanting in HIS house!
