I've had an unusual issue a few years now, so I thought I would ask for any ideas. There is a pair of robins that seems to think that our van's tire makes a good place for a nest. They are persistent, and even if you remove the nest, they'll be at it again the next day.
I don't particularly want to squash them or their babies (if they ever manage to get that far!) when I drive out some day, but it's a nuisance to check the wheels every day before leaving and remove a bird's nest if required.
Any ideas on how to prevent them from nesting there?
