photo 6586: Yellow-legged Gull michahellis 2cy, September 30 2001, Boulogne-sur-Mer, NW France. 

The patterned fresh coverts create a "less advanced moult stage" in this individual, compared to the one in the previous picture. Nevertheless, the actual moult stage is pretty much the same: the outer median coverts have been replaced recently and in the central lesser coverts a few grown-grey based feathers can be found. Still, these feathers have sub-teminal brown patterns and don't appear adult-like at all.

The head and under-parts have been moulted. Primary P10 is fully grown, resulting in a primary moult score (PMS) of 50. See Gull Topography for explanation of PMS.
The old coverts and tertials show a contrast between the black-brown centres and the white fringes and tips.
