3cy or 4cy heuglini, with complicated moult sequence. Left wing: P1-P2 missing, P3-P5 seem to be old (2nd gen?), P6 is adult-like, P7 is old again (2nd gen?), P8-P9 are fresh, with a mirror on P9, P10 is old again (2nd gen?, no mirror). Tail seems to be completely white, but not seen fully spread. pattern on outer secondaries probably in line with what could be expected for 2nd gen feathers.
