Yellow-legged Gull (Larus michahellis), 1cy, 6.10.2010, Aarhus Harbor

This is apparently the third 1cy Yellow-legged Gull in Aarhus this autumn which makes it quite a spectacular season. Judged on plumage and proportions it is different from the first and the second.

All scapulars and mantle feathers are moulted to second generation, all tertials are still juvenile, some lesser coverts and also few inner median covert are second generation

Note the rather worn white tertial fringes, the white primary tips start to turn brownish

Note the "apical spots" on p2-p4, in comparison to 1cy Caspian Gulls

The under-wings are dark showing a typical fine dark marked pattern

Note the typical tapering solid black tail-band; the rectrices are clearly white from the top of the tail-band till the base of these feathers with only a few dark spots
