I returned to the small former watercress bed several times during my lunch hour, as this was the place I saw the Kingfisher earlier in the week, I stood and waited for about a total of 30 mins, hidden behind a bramble patch peering out for a glimpse. Nothing, I could hear a pair calling quite frequently to my right on the main river, but nothing appeared in-front of me. There was however a small bird on the drainage pipes from the other cress beds which enter the pool, Sat preening in the midday sun, not once giving me a glimpse of its tail or wing weathers. The only identification I can give is a Grey Wagtail, possibly a juvenile, attached below are some pictures. Please let me know if you have any other ideas.
