Yellow-legged Gull michahellis 2CY, October 14 2001, Westkapelle, the Netherlands. 

Typical 2CY michahellis for October. Some lower lesser coverts have been shed and new grey feathers are growing. Note the fresh upper tertials, which have a different pattern: they appear plain grey. All the visible median and the inner greater coverts have been replaced by plain grey (probably fourth generation) feathers. The lesser coverts which were moulted last in row in the complete moult still show an obvious barred pattern. A few central lower scapulars superficially resemble second generation feathers, showing a sub-terminal brown band and a prominent shaft streak.
