Golden Eagle

The golden eagle is the most widely distributed eagle and a well-known bird of prey of the Northern Hemisphere. Adults are dark brown with lighter golden-brown plumage on the nape, a bill dark at the tip and fading to horn colour, and a yellow cere, while immatures usually have white on the tail and often on the wings. Females of the large Himalayan form are about 37% heavier than males and have nearly 9% longer wings; in the largest subspecies males weigh about 4.05 kg and females about 6.35 kg (Wikipedia, general species account).

It uses agility and speed with powerful feet and large, sharp talons to hunt a variety of prey, mainly hares, rabbits, marmots and other ground squirrels. It builds large nests on cliffs and other high places, to which it may return for several breeding years, and females lay up to four eggs and incubate them for about six weeks (Wikipedia, general species account).
