The observer is confident it concerns a Glaucous but I don't see how to exclude a larger Iceland like this one

I don't see these species often enough to confidently ID by jizz but hopefully someone on this forum can

Re: ID white-winged gull from single flight shot
Hi Ruud,
on brief and/or distant views, it can be really difficult to separate these two species in flight.
However, when the bill can clearly be seen, as here, identification is much easier.
With such a small and greenish bill, I think there can be little doubt that this is an Iceland Gull, not Glaucous...

Thanks Peter, apparently the observer has come to the same conclusion!
