Stercorarius skua
The Great Skua, *Stercorarius skua*, is a formidable and opportunistic seabird of the North Atlantic, renowned for its piratical lifestyle. A large, robust bird, it typically measures 50-58 cm in length with an impressive wingspan of 125-140 cm, and weighs between 1.2 and 1.8 kg. Its plumage is predominantly dark brown, often with a streaky appearance, though a diagnostic pale flash is visible at the base of the primary feathers, particularly in flight. Taxonomically, it belongs to the family...
Primarily a pelagic species, the Great Skua inhabits open ocean environments outside the breeding season, returning to coastal and island tundra, moorland, or grassy cliffs for nesting, typically at sea level.
The diet of the Great Skua is highly opportunistic, comprising primarily fish (stolen or caught), seabird eggs and chicks, small birds, carrion, and discards from fishing vessels, with kleptoparasitism being a key foraging method.
Great Skuas are diurnal predators, spending their non-breeding periods patrolling vast stretches of open ocean. Their foraging strategies are diverse, famously centered on kleptoparasitism, where they relentlessly harass other seabirds like gannets, gulls, and puffins until they drop or regurgita...
The Great Skua is primarily a North Atlantic species, breeding colonially on remote islands and coastal moorlands. Its main breeding strongholds are found across the Northern Isles of Scotland (Shetland, Orkney), the Faroe Islands, Iceland, coastal Norway, and small populations in Ireland and Bri...
