glaucoides - kumlieni

(last update: January 26, 2012)

Iceland / Kumlien's Gull 4cy, February 08 2012, Peterhead, Scotland. Picture: Chris Gibbins.

Age 4cy: showing adult-like inner primaries, clean yellow bill, but several immature patterns on coverts probably indicate 4cy, not 5cy. "Ghosting" adult-like patterning on otherwise white primaries: darker outer-webs on P8-P10 combined with a sub-terminal bands, and these darker outer-webs on the primaries are noticable darker than the primary coverts.

Primary category: --

Iris without obvious speckling, pale yellow.
