The golden eagle is an imposing mountain bird of prey. Adults have dark brown plumage with golden hues on the nape of the neck. Its powerful wings enable majestic flight. It prefers large open spaces and mountainous areas for hunting, feeding mainly on small and medium-sized mammals but also on carrion. Golden eagles are territorial and can often be seen soaring through the skies in search of prey. They nest on inaccessible rock faces or large trees, beginning to build their nests in the spring. They are known for their fidelity to their mate and territory. Their keen eyesight allows them to spot prey from a great distance.
