In the end I saw two second-winter Caspian Gulls and both were present at the A5 Lagoons at the same time during the afternoon. I'm pretty sure that one of them was the bird I spotted at the landfill site earlier in the day. The one below appears to have quite pale eyes. Seen closely they are coffee coloured.

As well as the Caspian Gulls, at least five Yellow-legged Gulls (four adults and a fourth-winter) were in the area. Numbers of LBB Gulls have fallen at the moment, but over a thousand Herring Gulls using the site.
