Lesser Black-backed Gull 1.C 3CY, June 16-22 2013, Noordwijk, the Netherlands. Picture Maarten van Kleinwee & Ruud Altenburg. White tibia 1.C, ringed by Roland-Jan Buijs & Hans Keijser, pullus ringed July 01 2011 at Europoort (Tennesseehaven), Rotterdam, Zuid-Holland, (NL5158.00N 405.00E). Recoveries: Bird is somewhat advanced in covert moult and a few tail-feathers have been renewed at the winter grounds (but no primaries or secondaries). Lower tertials also replaced, which may indicate sometimes an interesting secondary pattern, but not here. |
