Great Black-backed Gull - Larus marinus

    Description

    The largest gull in the world. It is bulky, and has a powerful bill. The adults have blacker wings and back than the smaller Lesser Black-backed Gull. The conspicuous white spots at the tips of the primaries are often referred to as "mirrors". The legs are pinkish, and the bill yellow with a red spot. It has a heavy flight and can look quite hunched when perched. They take at least four years to reach maturity. Young birds have scaly black-brown upperparts, and a neat wing pattern.
