Robot Lawnmowers Are Killing Hedgehogs (wired.com)
An anonymous reader shares a report: While Americans still wrangle their overgrown lawns by pushing or riding a lawnmower, many Europeans have handed off that responsibility to robots. These beefy, Roomba-like mowers loop their way around a yard, keeping grass trim and neat. To many of their users, the bots are endearing. Their owners give them names or cover them in decals of ladybugs or bumblebees. But the sentimentality only goes so far, because these blades-on-wheels have also been slicing up something other than grass: hedgehogs.
Erika Heller, a long-time hedgehog advocate with a Swiss nonprofit called Igelstation Winterthur, estimates that nearly half the hedgehogs brought to the group during the last couple years were injured by robot lawnmowers. These injuries include limb amputation, cut bellies, or even scalping. And that's not including the ones that have been killed outright. "The ones that have died we don't see, because they don't get brought here." In the United States, despite a wealth of children's toys and clothing featuring hedgehogs, the only live animals you're likely to see are in the zoo or, more controversially, kept as pets. But in Europe, wild hedgehogs are beloved. They're popular in European folklore; there's even a famous British poem about a hedgehog killed by a lawn mower.

When windmills were first brought to Ontario, there were a number of bird deaths but after a while these decreased to zero and now you'll see birds fly between the blades of windmills, playing with them. Deer that aren't around humans are easier targets for hunters. Shouldn't the same thing happen with hedgehogs and lawnmowers?
It's a form of (un)natural selection, the hedgehogs's environment has changed and the ones that are more cautious and wary of the lawnmowers will become the ones that survive and move forwards.
When hedgehogs perceive danger they roll up in a ball.
If they evolved to run instead, they might become more vulnerable to predators such as foxes and badgers because they can get past the spines easier.
