Yellow-legged Gull
Larus michahellis
Yellow-legged gulls were once found mainly in the Mediterranean but have spread in recent years as far as Britain and the Baltic. There are many of them at Lake Neuchâtel
and are probably the most numerous gull there. The first two are adults and the last one is a first-winter bird
