Seawatching Port Eynon

adult dark phase Arctic Skua
 While watching impressive passage of Manx Shearwater past Port Eynon this morning a couple of Arctic Skuas also went past. An adult with a juvenile, and I'm guessing the juvenile of the adult? The juvenile bird following the adult closely behind and never leading during pursuits or more relaxed flight.

05:40 to 08:30. Birds passing east except where shown.

32 Common Scoter (west), c100 Gannet, 4000+ Manx Shearwater, 2(dp) Arctic Skua, 1 Sandwich Tern and 2 Guillemot (on sea with heavy wing-moult)

Manx Shearwater
05:45 - 06:00 = 558
06:45 - 07:00 = 706
07:45 - 08:00 = 337

Peak passage occurred between 06:00 and 07:30. During this period I would approximate total numbers passing, heading east, to be 3500+ but after 07:30 a definite movement of birds passing west occurred, albeit in smaller numbers. It would be fairly safe to claim in excess of 4000 Manx Shearwater past Port Eynon this morning.
