Bank voles from the Alps are known to be larger (Claude 1970, 1995), but the relationships between body size, sexual size dimorphism, population dynamics and survival have not been thoroughly inves-tigated. How to tell the difference between a brown rat and a water vole. But I have seen bank voles swimming so be aware of the possible confusion. Occasionally, voles eat snails, insects and animal remains.

Diet Wood mice and bank voles eat seeds, fruit and nuts. The fur of the Field Vole also appears somewhat more unkempt, at times covering the ears and nose though after a good downpour or run in with a cat I am sure a Bank Vole could appear equally as bedraggled.

The Bank voles, living nearby roads, are threatened by lead exposure. Harris et al place reliability estimates of ±50% on their population estimates for the wood mouse and the bank vole, while for the field vole they believe that despite variable data its relative position is unlikely to change. When all you've seen is a flash of brown fur, it can be hard to know whether it was a water vole or rat. Breeding female water vole burrow with grazed lawn at water’s edge.
