Had three ringed Med Gulls by the Arun just south of Arundel over the last two days which give some clue to where some of the 250+ you had at Climping a couple of days back came from. All three were ringed at the Total site in Antwerp, Belgium. Today’s bird (white 33HA) was a >3CY ringed on 12 May 2020 and still at Antwerp on 13 June. The two seen yesterday were white ring 3852, ringed as a pullus in June 2018 and since seen in May 2019 in the Vendee, France; and white ring 3001 ringed as a >3CY in May 2018 and since seen in Brittany in December 2018 and Zwin in Flanders in June 2019.
