AGE – BEST CRITERIA:
Moult contrast present in the wing of 1cy, generally among central or outer GC, and in a few birds also in TT or RR. Adult birds show a uniform and freshly moulted plumage.
1cy October (male). GC1-3 juvenile, contrasting to post-juvenile GC4-10. Juvenile outer GC are worn and paler grey with narrow white tips while the inner post-juvenile ones are darker greyish black, showing a wide rusty tip. [1ET80898]
1cy October (male). Juvenile PC are generally slightly narrower and paler (brownish-) grey with variably worn tips and edges. Note the single juvenile GC1 which together with the PC contrasts to the moulted post-juvenile inner GC2-10. [1ET80601]
1cy September (male). Uniformly juvenile RR, typically rather narrow and with pointed tips. However, note that some individuals show more adult-like RR than this. [1ET80499]
