Bird poop CAN affect peoples health. We had a pigeon problem down on Galveston Bay. They roosted on top of our roof. In dry weather you didn't notice but when the rains came, it all came washing down. In my investigations in figuring out what to do about it I ran across all kinds of scary info about things you can catch from it.
