Ringed as pullus on May 03 2004 at Palmaria (Genova), Italy.

P1-P10. 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 MC, new inner GC and growing TT.
