2cy heuglini with complete juvenile tail, except R6 at both sides. Juvenile secondaries (except S17-S18 left and S16-S18 right wing) and recent moult in the primaries (P1-P3 replaced fully grown, P4-P5 missing, P6-P10 still old juvenile). At the wintering grounds, it replaced all tertials to 2nd gen but these feathers are worn at the tips again, and almost all wing-coverts (except outerhalf of the gc). Bill-base pale, dark iris.
