L. f. graellsii 2cy NLA 5.462.871 July 29 2011, Barneveld, the Netherlands. Picture Maarten van Kleinwee. Ringed as pullus on July 01 2010 at Rotterdam - Europoort, The Netherlands. Second-calendar year Lesser Black-backed Gull moulting to second-winter (second-basic, second cycle) plumage. The newly acquired coverts and tertials look fresh and show a clear pattern. Some of the inner greater coverts are missing, thereby exposing the underlying (bleached) secondaries. The pointy, first-generation primaries are somewhat bleached. |
