I have some doubts, mainly with the Glaucous/Icelandic pair, but also with others (from left to right in each picture):
1.- 2 GBBG adults and Glaucous gull? (Jokursalon, S Iceland)
2.- 1 GG adult, 1 Icelandic (?) NW fjords
3.- Glaucous? Husavik (N)
4.- Icelandic? Not really sure at all- Husavik (N)
5.- This group I assumed was all formed by Icelandic gulls (white remiges), but when I lloked at the photo was surprised to see that the individual at extreme left shows a pattern more similar to HG. Are all the same species (being hidden the black someway in the others), is this a hybrid? I'm a little lost. Photo was taken in the NW fjords
