2cy heuglini with complete 2nd gen tail moulted at wintering grounds. Juvenile secondaries and recent moult in the primaries (P1-P3 replaced fully grown, P4 growing, P5 missing, P6-P10 still old juvenile). It replaced all tertials to 2nd gen, and all wing-coverts. Based on location, the fresh grey feathers in wing-coverts and scapulars are now probably 3rd gen. Bill-base pale, dark iris.
