Ad Pomarine Skua, Black-throated Diver, 7 Balearic Shearwater, Manx Shearwater, 17 Arctic Skua, 4 Great Skua, juv Common Tern, 3 Sandwich Tern, 4 Common Gull, 466 Kittiwake (good passage incl. 63 juvs but sadly no Sabs!), 14 Common Scoter, 3 Harbour Porpoise.
Of interest this diver was initialy noted as GND, as a quick fly-by, by all present. Luckily I snapped this picture! Concensus of opinion now is imm BTD, as lacking GND's collar, has more pointed wings, highish white flank. But pretty sublte!
