3cy heuglini, with typical wing-covert and tertial replacement in the partial autumn moult, as seen in western taxa (upper tertials, inner gc, most mc, llc and lc). Visible outer primaries 2nd gen. Tail predominantly white, probably 3rd gen except maybe the outer feather right (R6) which seem to show much black.
