The Golden Eagle (Aquila chrysaetos) is one of the best known birds of prey in the Northern Hemisphere. Golden eagles are dark brown, with lighter golden-brown plumage on their heads and necks.
They eat a variety of prey, small or large mammals including foxes and young ungulates. They maintain territories that may be as large as 155 km2.
Golden Eagles nest in high places where they build huge nests to which they may return for several breeding years. They are monogamous and may remain together for life. Females typically lay from one or two eggs, and both parents incubate them for 40 to 45 days.
