2cy Lesser Black-backed Gull / Larus fuscus, Westkapelle - sea dike (The Netherlands) on 11 July 2008
Interesting individual, presumed intermedius. Note the adult like bill pattern, some dark black scapulars & greater coverts and the second generation tail feathers. Also the legs have a yellowish hue and note the well marked under-wing pattern. The primary moult is not fast as well, only p1-2 are moulted to second generation primaries, p3 is absent and the worn p4-p10 are still present.
