Atlantic YLG (atlantis) 2cy, February 19 2009, Playa Blanca, Lanzarote - Canary Islands. Picture: Asier Aldalur.

Classic michahellis, with inner wing-coverts and upper tertials replaced in the partial autumn moult. These feathers normally replaced early in autumn and now bleached in February, unlike some LBBG, which may moult feathers by February, showing fresh feathers.
Juvenile flight feathers. In atlantis, often more than 1 sub-terminal bands on the outerweb of R6 (vs. Med michahellis).
