Actually, they do have a vulture problem at Myakka--black vultures and turkey vultures. I have been there several times, and the biggest problem is in the campground nearest the lake. Mostly the birds roost in the trees near the campground at night, depositing smelly poop, so every night about dusk, just when they are starting to roost, the camp hosts take this gun and shoot off what can only be described as a sort of fire cracker. It whizzes and makes a shrieking sound while doing spirals and sparking on the way up. Then it goes BOOM! Vultures do NOT like it, so they fly elsewhere. Overall, they are very badly behaved birds!
And they don't eat the wipers or rubber parts--just have fun tearing them up. Must be bored birds.
They mostly bother cars and trucks in the big parking lot by the lake, but don't like to get under Class C motorhome overhangs to get at wipers. However, it is suggested you put plastic grocery bags around the wipers and maybe even the side mirrors, fastening them with rubber bands or tape. In motorhomes or trailers, they prefer to land on the roof and check out things like the wiring to TV antennas and satellite dishes.
Never bothered mine there.
I have to tell you about my trip to a bird sanctuary in Sarasota. These are all sorts of injured birds that can't be released. Anyway, there was no one but me there, so I stopped in front of a cage with two black vultures. One kept cocking his/her head and looking at me. Finally, he hopped off his perch, flew to a corner of his cage, picked up an orange pumpkin squeaky toy, and then hopped over to me and dropped it in front of me!! Changed my opinion of these bad birds entirely. I think he must have thought I looked like one of the keepers.
The worst problems are down in the Everglades at Royal Palm. They have loaner tarps there to cover your car, but don't know what you can do with a motorhome.
