Kumlien’s Gull - Larus [glaucoides] kumlieni - Kumliens Måge

Straight forward Kumlien's Gull

Identified as Kumlien’s Gulls because they have dark shading on the outer webs of p6-p10 reaching the the primary tips.

Putative Kumlien's Gull

Identified as a putative Kumlien’s Gull due to the fact that there is subtle dark shading on the outer webs of p6-p10, a faint 'ghost mirror' on P10 and the faint dark shading on p6-p9 reach the primary tips.

Possible Kumlien’s Gull

Most have rather dark peppered eyes, light gray marbling on outer webs of outer primaries, faint pigmentation along the tip of the outer primaries (subterminal bands) and in several individuals photos give the impression of a diluted version of a “string of pearls”
