Young sp: The post-juvenile moult includes the body, LC, MC, and most often all GC, TT and RR. CC and innermost alula are generally also included (and sometimes all three alula). A moult contrast is generally found between post-juvenile GC and juvenile PC (but is not always easy to detect). Many birds also show moult contrast in alula, and a few show contrast in TT, RR, inner SS or in outer GC (outermost 1-3 GC are occasionally left unmoulted).
Adult SC: The post-breeding moult includes the whole plumage.

Number of GC included in the post-juvenile moult shown as percentage of 1cy birds at Ottenby 2011-2013 (n=609).
