It's only Rock and Roller but I like it
Interesting you mention it being only a few feet from the shoreline. Today presumably the same BT Diver which left Shustoke turned up at Carsington Water here in Derbyshire. At first it was in deep water but then made its way into a small bay where it was feeding only a few feet from the shorline. In fact, most of the time it was like it was surface feeding like a dabbling duck.
Not a great photo but here's one I took today.
Looks just like the Shustoke bird so good chance its the same individual.
