INTERESTING FACTS
During the summer they stake territories near Adélie penguin rookeries, raiding them for eggs, chicks, and also cleaning up carrion. Thus, they have earned the nickname, 'raptor of the south'. The South Polar Skua is named after the naval surgeon Robert McCormick, who collected the first specimen. They were formerly known as the McCormick’s Skua. They are recognized as the world's most southerly bird and have been sighted at the South Pole. Until recently, all the skuas of the world were thought to be a single species, but now some experts believe there may be as many as five species. On some southern islands, two forms nest side by side without interbreeding, proving that they are different species. A group of skuas are collectively known as a "shishkab" of skuas.
