A very interesting 2cy Common Gull with a strange wing pattern. The wing coverts were extremely dark but it was the mirror on p10 and the internal markings to the other primaries that I haven't seen before. The fruity light made judging the shade of grey difficult but it was certainly darker than the normal.
3cy Herring x Glaucous Gull. This could easily be put down as a Glaucous/Iceland if seen in fading light or at distance. It looked quite convincing when it was zipping about at 400m range.
