Other voles are available

Spotted this very tiny chap at White Lion Meadow - the bottle in front is a Tango bottle, so that gives an idea of scale. Much much smaller than a water vole. I'm told by, my friend at Wild About Britain, that this is a bank vole because it's darker than a field vole and its ears aren't quite as much on show.

Note a bit of vole-cut grass - possibly water vole - right in front of the bank vole's nose.
