The golden eagle is the second heaviest breeding eagle in North America, Europe and Africa and the fourth heaviest in Asia. [5] [15] For some time, the largest known mass authenticated for a wild female was the specimen from the A. c. chrysaetos subspecies which weighed around 6.7 kg (15 lb) and spanned 2.55 m (8 ft 4 in) across the wings.

A dead golden eagle collected on the Isle of Lewis had the highest concentration of organochlorine known from a modern bird in Scotland. [55] The higher effects of organochlorines in Scotland may be due to the fact that birds there consume a relatively high quantity of seabirds, as opposed to North America, where this practice is rare.

Cliff nests are preferred as nesting sites in most of North America. [26] In Northern California, tree nests were apparently mainly used. [27] In the forested landscape of western Washington, where large clear cut areas having provided suitable hunting habitat, golden eagles almost exclusively nest in Douglas firs (Pseudotsuga menziesii) at ...
Golden Eagles have had endangered status in the state of Maine since 1986, and remain a species of greatest conservation need in the Maine Wildlife Action Plan.
By far the widest ranging species of booted eagle is the golden eagle, which is distributed in most of North America (where it is the only species of the subfamily north of Mexico) and much of Eurasia including a majority of Europe, often along most mountainous terrains therein but also other land-based habitats with typically remote semi-open ...
It is estimated that about 60% of the American bird population found North of the Mexican border nests in the boreal forest. About half of North America's breeding species (over 300) make their home there. The following is a list of the North American birds reliant on the boreal forests.

The bald eagle is thought to be much more numerous in North America than the golden eagle, with the bald species estimated to number at least 150,000 individuals, about twice as many golden eagles there are estimated to live in North America. [19] [37] Due to this, bald eagles often outnumber golden eagles at attractive food sources. [19]
