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 do not replace many wing-coverts in the partial autumn moult as 1CY. In general, the wing-coverts panel consists mainly of abraded juvenile feathers. In this individual, the outer lower lesser coverts and outer median coverts are still present, indicating that the complete moult may not have started yet in the wing-coverts. Nevertheless, P1-P2 may be missing already.
All the tertials and wing-coverts appear juvenile, although there are at least one lower lesser covert and three lesser coverts of old second generation.

This is probably a female, together with two other 2CY michahellis.
