Yellow-legged Gull michahellis adult, October 01 2001, Le Portel, France (50.44N,01.35E). 

Primary P9 fully grown. Note the rather pale yellow bill, the limited black marking on the gonydeal angle and the relatively small white tips on the recently moulted upper two tertials, maybe indication this is a 4CY/5CY bird.
