1cy (female) October, showing a moult contrast where the innermost two TT are moulted post-juvenile, while the outer longer one is unmoulted juvenile. This contrast may sometimes be rather hard to see, but note the slight difference in wear (identical in the two inner feathers, more worn in the outer one) as well as in the colour and gloss of the centre, were the inner two TT are blackish and the longer one is more brownish.
