Oystercatchers at Scapa Beach

Lots of birds along the beach and out to the pier. Sandwich terns- 35-40, an Arctic skua was chasing them about and a bonxie over. Also over- cormorant, raven and red-throated diver. Turnstones, oystercatchers, redshank, ringed plover, gannets etc etc. Quite a grey day though, for photography.
