Black Headed Gull or not?...that is the question

[John the Ranger]

We had this gull on the Reservoir ( or rather the ice ) where i work, this weekend just gone, some people think it a Black Headed Gull others are not so sure. What does everyone think?

Bird in question is the one just to left of centre ( centre on 2nd image ). Plumage is brighter and differs from the rest.

Thanks
John

It looks like a leucistic Black-headed Gull to me, with a dilution of the normal pigmentation.

I saw a leucistic Redshank amongst c50 normal birds at Holkham at the weekend.
