Icelandic Gulls - a selection of interesting photos

Gull 1. Presumed Glaucous x Glaucous/Herring Hybrid. 1st winter -1st summer plumage.
ie. the bird is almost 1 year old. (or is it almost 2 years old?).

Gull1.

Gull 2 . Presumed 1st Summer Kumlien's type gull (?Kumliens/Iceland cross) as darkish edge to primaries but the outermost primaries don't appear to have dark shaddowing all the way up the feathers that you may expect in a classic Kumlien's.

Here's an interesting selection of Gulls I recently had in Iceland. I'm pretty happy about the species/hybrid status but I wouldn't mind a little help on the ageing as a lot of birds are probably moving out of winter into summer plumages at the start of March.
