Parking up I hooked up with 2 friendly fellow birders from Suffolk and began the long walk to the bird, and it was a long walk. What seemed like ages later we arrived to double the number of birders on site to 6!
The bird was showing distantly (approx 200yards) across the river on the mud with Ringed Plover and helpfully with Dunlin, which when close showed the size and plumage difference nicely. (life tick #372)
