There were about 200 Black-headed Gulls at Rufford CP yesterday, including three well known birds, 217A, 237A and V77K (see labels for details of these birds). The sighting of 237A was the first since March 2020 (see here). In addition, a new, 1st winter bird (born this year) bearing a Danish metal ring, VA5573 was seen.

Details received from the Danish Ringing Scheme show that the bird was ringed, as a pullus, 877km away, on Hirsholm, Denmark on 25th May 2020.
In addition to the gulls there were also two metal-ringed Mute Swans, W17370 and W17357. The former bird was also present on my last visit, and had been ringed by Birklands RG, 3km away in September 2014. W17357 had also been ringed by Birklands RG, 3km away. It was ringed, as a age 5 bird (born in 2015), on 10th February 2016.
