Great black-backed gull

Zoomed in picture of a large flock of herring gulls (mostly juveniles, and some adilts) standing on top of a rocky landscape with moss and grass growing between the rocks. There's white poop on the rocks, letting the gulls blend in perfectly.
Near-adult great black-backed gull standing on a rocky coastline, blending in well with its environment. The GBBG is a large gull, with pink feet and black wings, and this indivisual still has some white/brown juvenile feathers left on the wings.
