My thoughts are that these are an adult and juvenile Glaucous Gull. Am I correct?

Thanks in advance for any help with the ID.

No, adult Glaucous Gulls have complete white primary feathers. That's an adult Herring.

The young bird is probably a Glaucous Gull, but it looks a little dark (it might just be the photo, or could it be a hybrid Glaucous x Herring?). Anymore photos available?

Thank you for your help Mark, it is much appreciated.

That is the only image I have of the Gulls.

The young gull, I'd go for 'Viking Gull' (hybrid Glaucous x Herring) as the wing coverts, tertials and possibly the primaries look a bit too mottled darker for pure Glauc. This hybrid is very common in Iceland, reported to be up to 70% of the birds in some Icelandic gull colonies, so finding one shouldn't be much of a surprise.
