Black Park Road as it looks now, with (below) burrows and feeding signs.
A quick check along this stretch of the brook shows water vole presence every few yards. The vole pictured is one of the Edgeley Rad colony, but it has a wound on the left side of its head. I don't know how bad the damage is. You very often see one-eyed voles, or voles with scarring due to fighting, and they seem to manage all right. I suppose it depends whether the wound becomes infected or not.
