About

Arctic Skuas are large seabirds, about the same size as Common Gulls. They are pirates of the sea: chasing other seabirds, such as Puffins and terns, and stealing the fish they have caught. They can often be seen flying low and fast over the waves in pursuit of prey, and only come to land to breed. They are known to be very aggressive at their breeding grounds - dive-bombing anyone who gets close to their nests.

How to identify

Adult Arctic Skuas have two colour phases: a light phase, with a white belly and dark back and cap; and a dark phase, which is uniformly dusky brown. Arctic Skuas have two pointed central tail feathers that stick out beyond their main tail, and display broad, white flashes on the undersides of their wings.

Distribution

Nests on the moorlands of Scottish islands and in the far north of Scotland, but can be seen around the coast during spring and autumn migration.

Habitats

Did you know?

The Arctic Skua is also known as the 'Parasitic Jaeger': parasitic because of its habit of stealing food from other birds, termed kleptoparasitism'; and jaeger - derived from the German word for hunter - because of its predatory nature.
