Humber Skua sp


Very bad record shots of a Skua (Arctic?) seen on the Humber this evening, one of 3 Skua sp. seen at the same time. 2 of these flying more or less together and one larger one seen over near the North Bank and no photos as far too distant. Any comments/thoughts most welcome, I have little experience of Skuas having not done a great deal of sea watching etc. They were all viewed from the viewpoint behind the VC at Waters Edge CP
