No, I haven't been out breaking any lockdown rules in order to see some new gulls, the bird in the title is one that I recorded back in September 2019 (!) at Rufford, and the results of where and when it was ringed have just come back.
When I spotted the bird, a first winter, I could see that its metal ring had the word Germany stamped on it. After quite a few photos I managed to get the whole ring number and sent off details.
