Herring Gull (argentatus & argenteus)

(last update: February 11, 2013)

Herring Gull sub-adult, July 31 2015, Noordwijk, the Netherlands.

No ring, no provenance on origin nor on exact age. However, showing many features of local argenteus rather than Scandinavian argentatus, and set of characteristics indicate this age.

Probably 4CY bird, maybe best labelled 'sub-adult'. Mirror on P10, combined with black in tail and brown in wing.
