This young adult is still fairly bold.
This vole had to make a hasty exit when a rival shot out from upstream and flung itself into the water.
Pygmy shrew, I think, because tail length is about 70% that of the body. Common shrews' tails are shorter, about 50%.
I had to share with you Richard Steel's gorgeous video of a young water vole trying to eat a nettle: http://vimeo.com/73566838 Towards the end of the clip, you can see there seems to be a bit of an issue with stinging. Nevertheless, the vole carries on!
