2cy+ male, October. Adult TT have a silvery-grey ground colour, fading towards blackish on inner web of T3 and T4, and towards warm brown and blackish on outer web of T1 and T2. (The T4 is actually missing here, as the browner feather looking to be T4 is actually the longest tertial-c retained from previous moult.) Adult TT are broader and generally show less signs of wear compared to juvenile TT. Adult tertial-c are broad and grey, the outer usually broadly tipped chestnut (although not in this individual).
