Yellow-legged Gull (Larus michahellis), ad female, 28.7.2009, Lakolk Strand, Rømø (#2)

This Yellow-legged Gull has a typical female-like bill with strong colours, red orbital ring and yellowish iris, yellow legs, darker upperparts with more saturated blue grey tone than on argentatus in direct comparison, slender, long-legged and long-winged appearance with elongated body profile. On the opened wing the four inner most primaries are all new generation feathers with p4 still grown and with a small black spot on outer edge, both p5 and p6 are missing, p7, p8, p9 and p10 has not yet been shed allowing us to view the large amount of black on these feathers and the isolated mirror only on p10.
