Spent an hour in the teeth of the gale on Mountbatten Breakwater, Plymouth Sound, with nothing other than a juv Kittiwake to show for it. Returned to the car park, where in the bay below were c.2dozen Black-headed Gulls and in their midst a single Leach’s Storm-petrel. (one of 20+ recorded in S.Devon today).  Conditions were not great, so was pleased to obtain one recognisable photo.
