Our elderly lovebird is about 16 years old. It suddenly occurred to me a couple days ago that he or she may be gradually losing his eyesight. Is that common in elderly lovebirds? Sometimes he holds his head at a weird angle as if he can't see clearly, i.e. that his peripheral vision is better than looking straight at something. He is not hand tamed and does not like to be held or touched. But when I put my hand in his cage the other day he did not react to my hand being near him until I touched his tail feathers. Then he got all alarmed. That is what lead me to think his eyesight is not quite what it used to be. He clambers all around his cage as if he can see, but I suppose he knows the whole thing by heart. He hasn't flown in a long time, which I had assumed to be because he was old. But perhaps he can't see well enough to fly.
