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

There are six extant subspecies of Golden Eagle that differ slightly in size and plumage. Individuals of any race are somewhat variable and the differences between subspecies are clinal, especially in terms of body size. Other than these characteristics, there is little variation across the range of the species. Some recent studies have gone so far as to propose that only two subspecies be recognized based on genetic markers: Aquila chrysaetos chrysaetos (including A. c. homeyeri) and A. c. canadensis (including the races A. c. japonica, A. c. daphanea and A. c. kamtschatica).
- Aquila chrysaetos chrysaetos (Linnaeus, 1758) – sometimes referred to as the European Golden Eagle. This is the nominate subspecies. This subspecies is found almost throughout Europe including the British Isles (mainly in Scotland), a lion’s share of Scandinavia, southern and northernmost France, Italy and Austria. In Eastern Europe, the race is found from Estonia to Romania, Greece, Serbia and Bulgaria in southeastern Europe. It is also distributed through European Russia, reportedly reaching itself eastern limit around the Yenisei River in Russia, also ranging south at a similar longitude into western Kazakhstan and northern Iran. Male wing length is from 56.5 to 67 cm (22.2 to 26 in), averaging 62 cm (24 in), and female wing length is from 61.5 to 71.2 cm (24.2 to 28.0 in), averaging 67 cm (26 in). Males weigh from 2.8 to 4.6 kg (6.2 to 10 lb), averaging 3.69 kg (8.1 lb), and females weigh from 3.8 to 6.7 kg (8.4 to 15 lb), averaging 5.17 kg (11.4 lb). The male of this race has a wingspan of 1.89 to 2.15 m (6 ft 2 in to 7 ft 1 in), with an average of 2.02 m (6 ft 8 in), with the female’s typical wingspan range is 2.12 to 2.2 m (6 ft 11 in to 7 ft 3 in), with an average of 2.16 m (7 ft 1 in). This is a medium-sized subspecies and is the palest race. As opposed to Golden Eagles found further east in Eurasia, the adults of this race are a tawny golden-brown on the upper-side. The nape patch is often gleaming golden in color and the feathers there are exceptionally long.
- Aquila chrysaetos homeyeri Severtzov, 1888 –This race occurs in almost the entirety of the Iberian peninsula as well as the island of Crete, though is absent from the rest of continental Europe. It also ranges in North Africa in a narrow sub-coastal strip from Morocco to Tunisia. A completely isolated population of Golden Eagles is found in Ethiopia’s Bale Mountains, at the southern limit of this species range worldwide. Although this latter population has not been formerly assigned to a race, the probability that it belongs with A. c. homeyeri seems high. This subspecies also ranges in much of Asia Minor, mainly Turkey, spottily through the Middle East and the Arabian Peninsula into northern Yemen and Oman to its eastern limits throughout the Caucasus, much of Iran and north to southwestern Kazakhstan. Male wing length is from 55 to 64.3 cm (22 to 25.3 in), averaging 59 cm (23 in), and female wing length is from 60 to 70.5 cm (24 to 27.8 in), averaging 64 cm (25 in). Weight is from 2.9 to 6 kg (6.4 to 13 lb) with no known reports of average masses. This subspecies is slightly smaller and darker plumaged than the nominate race, but is not as dark as the Golden Eagles found further to the east. The forehead and crown are dark brownish with the nape patch being short-feathered and a relatively light rusty color.
- Aquila chrysaetos daphanea Severtzov, 1888 – known variously as the Asian Golden Eagle, Himalayan Golden Eagle or Berikut. This race is distributed in central Kazakhstan, eastern Iran and the easternmost Caucasus distributed to Manchuria and central China and along the Himalayas from northern Pakistan in the west to Bhutan in the east (rarely ranging over into northernmost India) discontinuing in northeastern Myanmar. This subspecies is the largest race on average. Male wing length is from 60 to 68 cm (24 to 27 in), averaging 64 cm (25 in), and female wing length is from 66 to 72 cm (26 to 28 in), averaging 70 cm (28 in). No range of body weights are known but males will weigh approximately 4.05 kg (8.9 lb) and females 6.35 kg (14.0 lb). Although the wingspan of this race reportedly averages 2.21 m (7 ft 3 in), some individuals apparently are much longer-winged. One aforementioned female “Berikut” had an authenticated wingspan of 2.81 m (9 ft 3 in), although she was a captive specimen. It is generally the second darkest race, being blackish on the back. The forehead and crown are dark with a blackish cap near the end of the crown. The feathers of the nape and top-neck are rich brown-red. The nape feathers are slightly shorter than in the nominate race and are similar in length to A. c. homeyeri.
