| 4cy Yellow-legged Gull / Larus michahellis, Westkapelle - sea dike (The Netherlands) on 15 November 2007 |  |  |  |
Three different 4cy Yellow-legged Gulls. The first picture is taken on 15 November 2008, the second on 30 October 2009 and the last on 2 September 2009. All three birds are similar to 5cy+ Yellow-legged Gulls, but note the large amount of black on the bill and the dull yellowish legs (and base of the bill). The last one is closer to an adult type Yellow-legged Gull than the two above but note that the picture is taken more than two months earlier. Note especially the primary moult and the old outer primaries which give a good indication to age.
