Herring Gull (argentatus & argenteus)(last update: February 11, 2013) |
|
Herring Gull 5CY, 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 5CY bird, maybe best labelled 'sub-adult'. Some vestiges of brown in greater primary coverts. P2/P5. |
