Lesser Black-backed Gull
Lesser Black-backed Gulls are large gulls closely related to Herring Gulls. They are migratory, breeding across far northern parts of Eurasia; they winter as far south as western Africa. Like many other species of Larus gull, Lesser Black-backed Gulls take four years to reach maturity (including full adult plumage). They are omnivorous and will take some live prey (fish, insects, and others) as well as carrion and treats found in dumpsters.
