Young sp: The post-juvenile moult includes the body, LC, MC, and most GC (86% of the birds at Ottenby included all GC). Tertials, CC and alula are usually (but not always) included, and many also include both R1. Occasionally, inner SS may be moulted.
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=1516).
[The symbol + is used for birds showing irregular moult sequence.]
[Two categories of birds were excluded: 1) Birds that had not yet conducted the moult of the GC, and 2) birds where the assessment of the moult was deemed as less certain.]
