Polar birds are species that thrive in the extreme conditions of the Arctic and Antarctic regions. These birds have adapted to the cold climate, often featuring thick layers of feathers for insulation. Common examples include the Emperor Penguin and the Snowy Owl, which have unique behaviors and physical traits that help them survive in harsh environments. Many polar birds are migratory, traveling long distances to find food and suitable breeding grounds. They primarily feed on fish, krill, and other marine life, relying on the rich ecosystems of the polar seas. Their nesting habits often involve building nests on ice or rocky cliffs to protect their young from predators.
