Yellow-legged Gull (Larus michahellis), ad, 19.11.2011, Bønnerup Harbour

Note the slender and long-winged appearance with elongated body profile and long yellow legs.

Note the relative heavy bill with strong colours and red gonys spot reaching lower edge of upper mandible, yellowish iris surrounded by a thick red orbital ring, strong and round head profile.

There is a black band crossing p5 and a white mirror isolated from the white apical spot on p10. 

Note darker upperparts than argentatus in direct comparison.

The primaries have smaller white apical spots than the average argentatus.

Black extending fare down the p10 feather towards the primary coverts on the underwing without a grey tongue on the inner web which suites michahellis just perfect.
