I noticed this character earlier today by the Outfall of the Crossness Sewage Works (the tidal Thames). My automatic assumption was that it was a Black-Headed Gull but unlike the majority of said Gulls this one actually has a black head. And seemingly black beak. It is of similar size to other Black-Headed Gulls. I would be grateful for confirmation that it is a Black-Headed Gull please.
A million thanks .....
