Glaucous Gull
One of the largest gulls in the world, and the most opportunistic!
What you need to know about the Glaucous Gull
Our Expert Says… "Ever the opportunist, I've witnessed glaucous gulls hanging around beneath cliffs where they know guillemot chicks are about to throw themselves down as they leave the nests for the first time. If any don't make it to safety, glaucous gulls will come along and simply swallow them down whole!"
Amongst gulls, Glaucous gulls have the second largest wingspan in the World, but they are probably the heaviest. They breed around the Arctic regions during summer, and then migrate further south to over-winter.
Their upperparts are pale gray in color, underparts are white, and they have no black wingtips. They have a thick yellow bill with a red spot. The largest specimens can weigh almost 3kg (6lb), grow to 75cm (30”) in length, and have a wingspan up to 1.8m (70”) across.
Very powerful birds, glaucous gulls are opportunistic scavengers and predators. They have been known to eat fish, shellfish, carrion, small mammals, the eggs and chicks of other species, as well as berries and seeds. Some birds will even take down an adult kittiwake and they can often be found hanging around Polar Bear kills.
Glaucous gulls can be seen nesting in colonies, but also singly. They make a lined nest, either on the ground or on suitable cliffs.
