Herring Gull (argentatus & argenteus)

(last update: February 11, 2013)

Herring Gull 4cy, February 07 2013, Katwijk, the Netherlands.

Bird difficult to age, but complete grey scapular region and adult-like inner primaries suggest 4cy bird. Also, pattern on secondaries not what one wuld expect for 2nd gen feathers, more like 3rd gen.
