Yellow-legged Gull (Larus michahellis), ad, 15.9.2007, Bjødstrup, Djursland

This Yellow-legged Gull has fine needle-thin winter streaks in head centered especially around the eyes, heavy bill with strong colours and red gonys spot reaching lower edge of upper mandible, red orbital ring and yellowish iris, strong head profile, warm yellow legs, darker upperparts than argentatus in direct comparison, slender and long-winged appearance with elongated body profile. On the opened wing the seven inner most primaries are all new generation feathers with p7 half grown and a typical black band crossing p5, both p8 and p9 are missing and p10 has not yet been shed in the right wing. The fresh primaries have relative small white apical spots smaller than the average argentatus and the tip of p6 extends further beyond the longest tertials than seen on argentatus adding to the long-winged appearance of this species.
