Crazy Robin

We have this robin that keeps flying against our front windows. We kept trying things to stop him. Finally I hung ribbons from top to bottom on four different windows. When we put something on one, he would go to another. We've had this happen before, but this bird is very persistent. I think we finally have the windows so he won't bash himself. Although this evening I saw him sitting by the windows trying to figure out what was going on. Is there a life lesson in this I wonder?

To bed now,
