Map explanation
This map shows where changes occurred in the breeding season distribution of the species in Wiltshire between 1995-2000 and 2007-2012, as revealed by the fieldwork for Birds of Wiltshire (Wiltshire Ornithological Society 2007) and the shared fieldwork for Bird Atlas 2007-2011 (BTO 2013) and for Wiltshire Tetrad Atlas 2007-2012.

The Yellow-legged Gull, long regarded as a southern European race of the Herring Gull, was only formally recognised as a separate species in 2005. They breed from the Atlantic islands and northwest Africa, across the Mediterranean to Cyprus and on Black Sea coasts from Rumania to Turkey. In the 1970s they spread north to nest along the Atlantic coast of France and up the Rhone valley. They first appeared as non-breeding visitors in southern Britain in the late 1970s though it was not until 1997 that they were first recorded breeding, at a site in Dorset. Bird Atlas 2007-11 recorded just that one confirmed breeding record though there were records of probable breeding from two other sites in southern England and indications of possible breeding activity in three further squares. Non-breeding birds were recorded in summer in 307 squares in England and there were a similar number of records in winter with the addition of a scattering of records in Scotland.
The first record of a Yellow-legged Gull in Wiltshire was at Swindon rubbish tip in December 1985. Next came records from three sites in January 1987 and from then on there have been records in every winter. From 1995 onwards they began to be seen in late summer then in 1998 and 1999 in every month. Birds of Wiltshire recorded them at 17 sites in winter (though only three sites feature on the winter distribution map), and in at least one site in summer (though again this did not appear on the breeding season distribution map). WTA2 also recorded them at 17 sites in winter, and two in summer.
