Wicken wind pump

How have we never been to Wicken Fen before when it's so close!? I wasn't expecting the amount of wildlife we saw this early in the year. Main highlight - a caddisfly larva complete with little house made out of twigs and leaves. This nearly made it as today's photo but if I'm not careful every single one will be something animal or plant related so for a bit of variation here is the wind pump used to keep the fen wet.
