Final update (unless seen again) on green ringed Mediterranean Gull seen at Carr Vale on 11/12/2018 and 5/1/2019 (and presumed same at Pleasely Pit on 4/1/2019 where green ringed Med Gull but code could not be read). The bird was ringed on 8/6/2016 (not 16/6/2016 as I was told previously) at Solvesborg, Island of Norroren, Blekinge, south Sweden along with its sibling which bears a green ring. Since then it has been seen at Ferry Meadows Country Park, Peterborough, Cambs between 9/11/ and 14/11/2017.
