2cy heuglini, with standard post-juvenile moult on the wintering grounds: replaced tertials and all wing-coverts. Tail 2nd gen, except R5 right side (note white R5 left). Primaries and secondaries juvenile. Complete moult not started yet.
Several wing-coverts adult-like grey, obviously moulted last in line. The new grey inner mc and inner gc are probably 3rd gen (based on location), while the central gc with similar pattern and freshness are probably 2nd gen.
