After yesterday's trip to see the Greater Sand Plover, I popped into Rufford CP to see which Black-headed Gulls were around. I was there for just over an hour and saw c.50 Black-headed Gulls, including 4 green-ringed gulls: 246A, 258A, 293A and 297A. I was particularly pleased to see 246A, as this was the first ever Black-headed Gull that I ringed, back in December 2019 (see here). It was aged as a 3, meaning it was born in 2019, so it's now into its 3rd year. It was reported at Rufford, and nearby Center Parcs, throughout the winters of 2020 and 2021. This sighting is the first of this winter. There haven't been any reports of it during the summer months, so we don't know, yet, where it breeds.
