Brief introduction: The White tailed eagle (Haliaeetus albicilla groenlandicus (Brehm, 1831)) is one of the largest birds of prey belonging to the Accipitridae family and is considered a close cousin of the Bald Eagle. The White-tailed eagle has a large bird wingspan that measures 1.78–2.45 m, and is an apex predator, meaning it is a predator with no predators of its own.
