Geelpootmeeuw | Yellow-legged Gull | Larus michahellis
2cy Yellow-legged Gull / Larus michahellis, Westkapelle - sea dike (The Netherlands) on 22 October 2008
Note the dark gray upper-parts in comparison with the adult Herring Gull right in the background. Nearly all scapulars, most median coverts, a few lesser coverts, the innermost greater coverts and upper tertial are replaced for grayish adult-like(probably fourth generation) feathers.
