Some years ago I was out walking with my camera when I came to a small stream. I noticed a little movement in the water and saw to my surprise a creature swimming. I realised I has spotted my first water vole. I kept perfectly still and it it carried on feeding and totally ignored me.
I watched it for a good ten minutes while it went about its business of feeding.
It swam up and down as though it was showing off.
In the end it came and sat on the grass not more than a couple of metres away and watched me.
I have had some strange experiences with wild animals but I think this one takes the biscuit. I went back several times over the following years but never saw it again.
