On the flight picture note the primary moult stage, p1-p6 are fully grown (note also the limited amount of black on p6 and the complete absence of black on p5), p7 is still growing, p8 is absent and p9-p10 are still old primaries. Recently the moult wave in the secondaries has started and the outermost one is just replaced and still growing. And the outer and middle greater coverts are recently replaced by new generation dark-blackish coverts.
