Siberian Gulls were very dominant, with about 150 - second commonest gull after armenian. This adult (male?) is in typical moult stage, with P7 to P10 unmoulted, and S1 growing. Look at this amazing eye!
Another, smaller and more delicate bird, a female?
I had my first Caspian Gulls of the season - 2-3 adults and another 10 or so 1cy's. I also had a Steppe-type Gull, but no images of it.
