A bit of a 'lawn' outside this right-hand burrow above.
Water vole burrows are about the diameter of a Pringles tube. They are neat, no spoil heaps at the entrance, and usually fringed by nibbled grass. They are often very close together to give maximum chance of escape. Some entrances will be underwater, and some high up on the bank so the vole can deal with flooding and again escape more easily.
Unusually long water vole droppings.
Droppings and feeding together.
