I need an ID of this gull taken at Saltholme Back.

Rob,

  Checking my Seabird in flight guide, its a Black Headed Gull in plumage change.
Could be totally wrong. But I'm 95% certain.

What about the Black spot on the wing?

Ermm,

Was more interested in the red legs, black bill White outer primary and single mirror on the under wing.
Black spot, ??
As I said, could, am, wrong

It is indeed a Black-headed Gull, moulting into summer plumage.

Not sure which black spot is worrying you, but if it's the large one at the base of the right wing, that's just a shadow.

OK I'm almost convinced. (95%)
