New 2w Iceland Gull at the fish factory today (bottom bird) . This bird has pure white wings and tail unlike the bird present during the last few months, which had a lot of brown shading on the tail and primaries (third photograph down).
The second photograph down shows another 2w Iceland Gull that has been seen at Aberaeron. This again is quite a pale bird but unlike the gull present at the fish factory today the tip of the bill isn't wholly dark (not easy to see in this shot) with the very end of the bill being noticably pale.
The first photo isn't an Iceland Gull but a cracking [2w] leucistic Herring Gull - not seen today, but photographed at New Quay last month. A second leucistic bird has also been present but this has more brown marbling on the wings and tail.
And if that wasn't enough a very smart adult Yellow-legged Gull also at the fish factory today.
