Not a brilliant picture, I grant you, but the first one since May. There was so much nibbled watercress under the bridge, I thought I had a chance of seeing a water vole if I stood there long enough.
Added later - went to check the Prees Branch Canal this evening and found plenty of water vole evidence, including a feeding station made of chewed horsetail. I know w-vs eat over 200 species of plants, but I've never seen them chop up horsetail before. There were about four little piles of it, so the vole must have been keen. On the drive back I stopped near Dobson's Bridge ( http://staggsbrook.blogspot.com/2008/08/voles-where-ive-not-seen-them-before.html ) and saw another water vole swimming in the brook there.
