Golden Eagle Hunting A Sika Deer, Lazovsky District, Primorsky Krai, Russia

- Aquila chrysaetos kamtschatica Severtzov, 1888 – sometimes is referred to as the Siberian Golden Eagle or the Kamchatka Golden Eagle. This race ranges from Western Siberia (where overlap with A. c. chrysaetos is probable), across most of Russia, including the Altay (spilling over into Northern Mongolia), to the Kamchatka Peninsula and the Anadyrsky District. This subspecies is often included in A. c. canadensis. Male wing length is from 61.8 to 70.5 cm (24.3 to 27.8 in), averaging 64 cm (25 in), and female wing length is from 65 to 72 cm (26 to 28 in), averaging 69 cm (27 in). No weights are known in this race. The coloration of these eagles is almost exactly the same as in A. c. canadensis. The main difference is that this race is much larger in size, being is nearly the equal of A. c. daphanea going on wing-length.
The larger Middle Pleistocene Golden Eagles of France (and possibly elsewhere) are referred to a paleosubspecies Aquila chrysaetos bonifacti, and the huge specimens of the Late Pleistocene of Liko Cave (Crete) have been named Aquila chrysaetos simurgh. Similarly, an ancestral Golden Eagle, with a heavier, broader skull, larger wings and shorter legs when compared to modern birds, has been found in the La Brea Tar Pits of southern California.
