This vole run was pointed out to us by the Ranger at the neolithic Ring of Brodger. There is evidence that voles were present and eaten in neolithic Orkney, but there are none in the Shetlands. There are thus also vole predators such as hen harriers and short eared owls in Orkney but not Shetland. Unlike the voles, other animals such as fox and snake have not crossed the Pentland Firth, so Orkney also has many ground nesting birds.
