Why would my cockatiel shake his head in response to certain sounds? Does it mean it hurts his ears? I posted a few weeks ago that I had gotten a recorder. He doesn't seem to mine it, pretty much ignores me when I am playing it. I guess I had hoped he might sing with me! But last night I came closer to his cage to play it and he kept shaking his head. Of course I stopped, because I didn't want to hurt his ears. I moved away to my usual spot and tried again, watching him closely and he didn't shake he head (I had never noticed him doing it before when I played) I guess as long as I am not too close it doesn't bother him. I certainly don't want to do anything to cause him discomfort.
