For the last 3 years I've popped up to Box near Bath in Spring to try and photograph Dippers on the By Brook.  Every year I've seen them, and managed to get a photograph.  But never one I'm totally happy with.  This year is the same.  I drove up early this morning, got some photos, but none are great.  Interesting to see a pair together, and one with a caddisfly nymph casing thing.  Also one photo with one of the Dippers blinking, showing its special underwater eyelid.
