We have a large supply of doves in my neighborhood. They drive me crazy. They're constantly sitting on my car and pooping on it. For a while I had a rubber snake and that seemed to keep them away. I think they decided it was dead and flew away with it--it's gone.
I have a carport. They seem to like my carport because it gives them protection from birds of prey, who tend to swoop down from above. We have a hawk that I call Henry [after Henry Hawk who wants to ear Foghorn Leghorn]. He doesn't seem to come after them under the carport. In fact, we used to have quail running around. They fly reluctantly and prefer to stay on the ground. Now, I do not see quail anymore. It could be the coyotes got them, but I think Henry did it. I just wish he'd switch his diet and eat more doves--a lot more of them.
