photo 6660: Yellow-legged Gull michahellis 2cy, October 01 2001, Le Portel, France.

Primary P10 is fully grown and all the secondaries and rectrices are second generation and complete. Hence, the complete moult has ended. After this complete moult, a partial moult has included some of the tertials and wing-coverts.
The two upper tertials have a greyish centre with buffish-brown basal half, the most recently replaced tertial, #3, is still growing and is slightly more adult-like in its pattern. The two inner greater coverts are missing, the other greaters show obvious brown barring on a white base (though to the base, these feathers become darker all brown). Most of the central median coverts are grey with a brown shaft streak, the inner median coverts are patterned as the greater coverts. In the lesser coverts, just a few have been replaced by grey feathers, the majority have dark brown centres and white fringes.
