Ringed as pullus on May 11 2004 at Fanel, Switzerland.
Complete moult: P1-P8 new, no old primaries left. 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. This partial moult started in this bird.
