Bird right: coverts replaced in post-juvenile moult, as well as upper tertials.

Warning: by November, the Atlantic coast of Portugal holds large numbers oif birds, including Lesser Black-backed Gulls (graellsii / intermedius), Mediterranean Yellow-legged Gulls (michahellis michahellis) and of course local birds (michahellis lusitanius). Sometimes, these three taxa may appear extremely similar, and ID is tentative. However, extremes of all forms are rather straightforward, especially for bird watchers from the region.
