Ringed as pullus on June 07 2006 at Fanel, Switzerland.

Complete moult: P1-P6 new, P9-P10 old. Gap in central GC already 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.
