Yellow-legged Gull michahellis 2CY, April 30 2003, Etaples, NW France (50.42N,1.34E).

2CY michahellis from late-April. This is an example of michahellis which shows advanced moult as it has replaced many wing-coverts and the upper tertials in the partial autumn moult as 1CY bird. In general, the back has already many grey third generation scapulars, the wing-coverts panel is a mix of abraded juvenile feathers, broad barred old second generation feathers and a few fresh second generation feathers which are grey-based. The old second generation feathers can be found in the three upper tertials, the three innermost greater coverts and most of the inner median and lower lesser coverts.
