I think this is a young moorhen but please correct me if I'm wrong. (I miss having Mark to tell me when I've incorrectly identified a bird). He/she was calling pitifully and I just wanted to scoop him up and take him home. Unfortunately, the bank of the river was very high and if I had fallen in I would have been in trouble. I dare say he would have swam away anyway - ha ha. This was taken by the River Ivel in Blunham which made a change from the River Great Ouse
Yes, please don't fall in the river! I can't help with identification but it looks quite tall but then I only normally see moorhens when they are swimming.
