I had the same problem....the same bird crapped on one of our cars 2 or 3 times every day, right on the side mirrors. I bought one of those plastic owls with the large glass eyes, and I have had a problem since. You are supposed to fill it with sand or anything heavy to get it to stay put, but I just stuck a stick up through it and let it move in the breeze looking down at our driveway. We'll see if it works in the long run.
