A large raptor similarly sized to Bald Eagles. Prefers highlands and more barren and remote locations. Usually found in such locations and are rare elsewhere such as valley bottoms. However, almost an annual visitor in the valleys. Feeds on mammals such as rabbits and marmots and large birds including grouse. Will also eat carrion but not as readily as Bald Eagles. Some migratory movement from northerly birds south. Breeding activity recorded in our checklist area.

Similar species:
Due to large size, not likely to be confused with hawks. Juvenile Bald Eagles can be similar and are often mistaken for Golden Eagles. Note the mottled white throughout the body, especially on the under wings, tail and breast of juvenile Bald Eagles. Juvenile Golden Eagles usually have well defined white patches on their carpal joints (at the base of the primary feathers on their wings) which is most visible from below. They are always white on the upper half of the tail which contrasts abruptly with the brown. They are otherwise dark brown with a golden wash on the nape of their neck. Adults lack the white found in juveniles. In flight, wing shape can also provide a clue. Golden Eagle's wings can appear broader at the tips and bulge along the secondaries (see photo below) more than the more slender Bald Eagle wings. This is not always evident. Soars with wings in slight 'v' similar but less than Turkey Vultures. Bald Eagles soar with flat wings.
