Yellow-legged Gull michahellis 4CY, July 27 2001, Le Portel, France (50.43N,01.37E).

Left is a 4CY with P4 growing and P7-P10 old. Note the primary mirrors on P9 and P10 and note the outer secondaries which are exposed to their base now all the outer greater and median coverts have been shed.

At the centre is a landing 3CY michahellis with P8-P10 old and P5 at the length of P4 (a few inches to go). This bird lacks a mirror on P10 -of course- and the secondaries show extensive brown centres. Another 3CY bird can be found in the far right of the picture, a bird raising the wings, with P5 new and P8 still old. This bird too lacks a mirror on P10.
