photo 7350: Yellow-legged Gull michahellis 3cy, August 09 2003, Etaples, France (50.42N, 1.34E). An example of a delayed moulting individual, delayed in primary moult score compared to average 3cy michahellis.
In 3cy birds, the old second generation flight-feathers are replaced by new, more adult-like third generation feathers. This is most obvious in the (outer) primaries. The old second generation P10 is brown, abraded and will be replaced by glossy-black fresh third generation P10 showing an obvious mirror. The primary moult stage in this bird: P7-10 are old second generation and P4 is full-grown. The landing bird is a 3cy Lesser Black-backed Gull, showing a small gap in the primaries (not uncommon in LBBG), with P6 almost fully grown and P8-P10 still old second generation. |
