In New Zealand, roadside stock warning signs tend to show sheep and cattle. In Australia, they are just as likely to show kangaroos. In England and Scotland, especially in Scotland, they warn most commonly of deer or red squirrels (much rarer than the introduced grey squirrel and therefore worthy of protection). We also saw one sign which warned of badgers.
We didn't see the animals nearly as much as we saw the signs, and when we did finally spot a deer, it was in an area where there were no signs. The same happened with the squirrels. Which may just possibly explain this sign, which left us scratching our heads a little...
(Yes, it's a little blurred, since it was taken from a fast-moving car).
