When I first started seeing Darvic ringed gulls about 10 years ago they were mostly Med Gulls from exotic places like Poland, Germany & Belgium/Holland. Nowadays they're much more likely to be Herring Gulls ringed at a Gloucester landfill or Black Headeds hatched along the M4 corridor.
So it is that 2nd CY BHG White 2X94 on April 2 at Newport had been ringed as a chick at Hosehill Lake, Berkshire on June 20 09. This was it's first subsequent sighting.
