Yellow-legged Gull lusitanius 1cy, November 28 2012, Peniche, Portugal. Picture: Rui Caratão.
Small, elegant Yellow-legged Gull, with rounded haed and short exposed tibia. This bird has the covert panel and tertials still juvenile (maybe GC1 replaced?). All scapulars replaced by late November.
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.
