. "The yellow-legged gull (Larus michahellis), sometimes referred to as western yellow-legged gull (to distinguish it from eastern populations of yellow-legged large white-headed gulls), is a large gull of Europe, the Middle East and North Africa, which has only recently achieved wide recognition as a distinct species. It was formerly treated as a subspecies of either the Caspian gull L. cachinnans, or more broadly as a subspecies of the herring gull L. argentatus."@en . . "Yellow-legged gull"@en . "IUCN3.1" . .
