If you have spent any time in Hannibal lately, then you (and your car) probably know that Hannibal has a pigeon problem. They city has a controversial plan on how to deal with the pigeons. While on the surface (or car window), it may appear that the city is just trying to deal with a nuisance. After much research (5 minutes on YouTube), I believe the Hannibal pigeons may be more dangerous than we think. Fed Ex learned of these dangers and exposed them in their Super Bowl ad back in 2008.
