We came across them toward the end of our walk. I had been trying to take photos of a heron who we found sitting on the path underneath a motorway bridge. Each time I got closer it would fly a bit further down water. Having followed for a bit, we decided to turn round and head back.
As I turned I saw a flash of blue, low over the water. We watched it swoop twice before turning and heading away with a fish. As we watched another appeared. I tried to take a photograph but they were too quick. We waited and within a few minutes they were back. Again, I tried to take a photo but again no joy. After about 15 minutes they disappeared. We waited for a few minutes and when they never returned we decided it was time to head home.
