Yellow-legged Gull michahellis 2CY, August 25 2000, Etaples / Boulogne-sur-Mer, NW France.

The tail has been renewed completely and the outer rectrices (R6) is still growing. Primary P8 is fully grown, P9 has to grow a few inches and P10 is halfway it's final length. Except the innermost one or two secondaries which are still growing, all second generation secondaries show a neat dark centre and a white zigzag pattern created by the neat white fringes (most obvious in the far wing). Note the grey scapulars and the predominantly white upper-tail coverts, contrasting with the broad tail-band. The central upper-tail coverts show a dense variegated pattern. The second generation inner primaries show a window, which is more obvious in 2CY than it is in 1CY, but still not as well-defined as in argenteus Herring Gull.
