In spring 2024 a number of Black-headed Gulls were present on the new scrap at Sculthorpe Moor in such numbers they attempted to breed, but all subsequently failed, initially through an increase in water levels causing a number to abandon, and finally the few remain abandoned later, possibly due to a predator, with no breeding recorded in 2024.
A number of Mediterranean Gulls were seen in small numbers amongst the Black-headed Gulls, leading to a hope they may also settle and attempted to nest, but it subsequently turned out these were just spring migrants moving through, presumable drawn to the site by the number of Black-headed Gulls.
On 7th April a pair of adult Mediterranea Gulls were present, one which was carrying a blue leg ring, which at the time appeared to be 5A75. This bird was from a Spanish colour ringing project, but when reporting the ring to the Spanish ringing scheme in San Sebastian, the ring 5A75 had not been used yet, and it appeared it could not be assigned to a specific bird.
A short article appeared in the November 2025 addition of the North-East Norfolk bird club bulletin which related to a Mediterranean Gull seen on the Sheringham playing field next to the cemetery, this bird being 5A25, on 15th and 20th October 2025. It became apparent the 2 had been misread as a 7 at Sculthorpe on 7th April.
The bird had been ringed as an adult on 23rd January 2024 at Entre Rota y Chipiona, Cadiz, a movement of 1876km.
