This is the pale extreme of argentatus spectrum. Of course its difficult to be certain about hyperboreus blood in this one, but you may expect to find a pink / sort of pink bill base in March In hyperboreus birds.

Hi
This photos are from Norway 01.05.2015. Ringers marked it as "presumed L. argentatus x L. hyperboreus. Bergenshybrid". Is very similar to the above gulls.
