Yellow-legged Gull michahellis sub-adult, October 01 2001, Le Portel, France (50.43N,01.37E).

Primary P8 already longer than P7 and all old primaries have been shed. Note the rather pale yellow base of the bill and the extensive black markings on the bill, indicative for sub-adults.

Below: pronounced black shaft streak in the outer primary covert, just visible beneath the greater covert row.
