Beskrivelse: This Caspian Gull had rather obvious tertial notches, which could be a sign og argentatus influence. However, it might apparently be witthin the variation of Caspian, although rare. It was ring with a metal ring, which I had problem to read properly. There are some more pic at Vår Skådarvärld on Facebook.
Beskrivelse: On a closer look (which I had forgot to mention,strange enough), there´s actually moult going on in the upper lower scapular. Also a few missing. This can also be seen in the first pic of this bird.
So - that would make it a juvenile moulting to first winter, or 1cy/first cycle to be more correct.
