      Gull michahellis 2CY      HES M015462 September 11 2005, Hauterive,  Switzerland. Picture: Stephane Aubry.
Visit Stephane's Pbase site. Ringed as pullus on May 11 2004 at Fanel, Switzerland. P1-P9 new, P10 tip at P7 (PMS = 49). Complete moult in coverts and tertials finished, gap in central GC  closed. It is commonly seen that, while the outer primaries are replaced in the complete moult, a subsequent "partial autumn moult" will replace feathers in upper tertails and several inner wing-coverts in late summer and early autumn, which explains the fresher grey adult-like coverts seen in 2nd winter birds. Active partial moult in this bird, note missing  upper tertial.
