For the next few months Herring Gulls are the dominant species at Shawell. Today I read colour-rings on no less than 13 Herring Gulls, which is the best total I've ever had for this species since I began recording colour-rings at Shawell back in January 2012.
The highlights from my Wednesday lunchtime visit and today were three Caspian Gulls and a colour-ringed Lithuanian large gull. It seems to be mostly Herring Gull, but I wouldn't rule out a bit of Caspian Gull blood.
Today's Caspian Gull was a first-winter, quite an advanced one. Not only has it replaced its scapulars, but also many of its coverts including some outer greater coverts. The other first-winter this week was not so advanced. The advanced bird was also there last Saturday.

The Lithuanian gull is the first colour-ringed large gull from that country that I have seen at Shawell. I have had a colour-ringed Black-headed Gull from there though. It was ringed as a chick during May 2015 at Kretuono ež. Didžioji sala, Švenčionių r., Lithuania. 55°14'45"N 26°04'45"E.
