Any comments on this 1CY Iceland Gull that I found today in Edinburgh, Scotland? Obviously it is a dark individual and shows some Kumlien's characteristics. My assumption is that it is a dark glaucoides rather than kumlieni... but that is based on an expectation that kumlieni should show distinctly darker outer webs of the outer primaries compared to inner primaries. On the other hand this bird certainly does not seem to show the white flight feathers that I have seen in other nominate Iceland gulls. However, I have little experience of the nominate form and no experience of kumlieni and wonder whether anyone else can confirm as either form or as unidentifiable. Note that the photos were taken in bright sunshine. Apologies for poor quality.

Many thanks
