From Andrew Sims - The Marsh Harrier was still at Marloes Mere at lunchtime, feeding 
successfully then sitting on the same bush as in Derek’s photo, finally 
around 3pm leaving towards the east then south towards Skokholm. There 
were also some Wood Sandpiper-like calls, but the bird was not seen. An 
increasing variety of waders was at the Gann lagoon at high tide this 
evening – ruff, sanderling, 3 ringed plovers with 6 dunlin, a green 
sandpiper, 5 redshanks and a few curlew passing over.
