The golden eagle (Aquila chrysaetos) is a member of the Booted or True Eagles family. Golden eagles can be found throughout much of the northern hemisphere. It lives in mountainous areas, prairie coulees, and other places where rugged terrain creates abundant updrafts. Size - Length of about 3 feet (.92m). Weighing up to 15 pounds (7kg), with a wing span of up to 7 feet (2m). Colour - Dark brown Lifespan - Fifteen to twenty years. Territory - The golden eagle is a solitary bird, which can be found in remote areas. They do not congregate in large numbers during the winter. Being a great hunter, the golden eagle seldom eats carrion. However, I have seen them attack deer on mountains in order to scare them from a safe foothold.. Its hunting territory extends up to 162 square miles (260 square km).
