Turnstone turning stones this morning amongst the rocks below the point of extension of West Pier, Whitby

Went to see the turnstones this morning, but none there. Small bird flew in amongst the rocks just as I was leaving. Once this purple sandpiper (Calidris maritima) realised I wasn’t moving, it got on with looking for food. Fortunately, the yapping dog was oblivious to its presence

A common starfish (Asterias rubens) is slow moving, but that is still faster than its relatively immobile prey of marine molluscs like mussels, as well as barnacles, sea snails and sea urchins
