It's only Rock and Roller but I like it

I found another Black-headed Gull sporting a yellow leg ring with black code TR0V at the Flashes this morning. There doesn't appear to be a record of this bird being seen at Upton Warren before. I think it was a first winter.
Also present again at both the Moors Pool and Flashes was T81U.
Yes, another new BHG and again it appears to be Polish in origin. I will follow up on the POLRING website.
