Great Black-backed Gull

Great Black-backed Gull

The great black-backed gull is the largest gull species in the world, towering over other seabirds with its commanding size and bold black-and-white coloration. Adults have a striking black back, white body, pink legs, and a large yellow bill with a red spot. Juveniles are mottled brown, gradually transitioning to adult plumage over four years. 


These gulls are powerful predators and scavengers, feeding on fish, crabs, smaller birds, and even carrion. Around Southend Pier, they can often be seen perched on posts or gliding majestically over the water. Their loud, deep calls add to their imposing presence. While they are less common than other gull species, their size and striking appearance make them easy to spot. 


They are a key part of the estuary's ecosystem, but their populations are carefully monitored due to their reliance on healthy coastal habitats.
