The downside is extremely limited since supply Up to 20 species have been classified in the genus, but more recently the taxonomic placement of some of the traditional species has been questioned.
Traditionally, the Aquila eagles have been grouped superficially as largish, mainly brownish or dark-colored booted eagles that vary little in transition from their juvenile to their adult plumages.
Genetic research has recently indicated the golden eagle is included in a clade with Verreaux's eagle in Africa as well as the Gurney's eagle A.
This identification of this particular clade has long been suspected based on similar morphological characteristics amongst these large-bodied species.
This genus has recently been eliminated by many authorities and is now occasionally also included in Aquila , although not all ornithological unions have followed this suit in this re-classification.
There are six extant subspecies of golden eagle that differ slightly in size and plumage. Individuals of any of the subspecies are somewhat variable and the differences between the subspecies are clinal , especially in terms of body size.
Other than these characteristics, there is little variation across the range of the species. 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 Weesie, Golden eagles are fairly adaptable in habitat but often reside in areas with a few shared ecological characteristics.
They are best suited to hunting in open or semi-open areas and search them out year-around. Native vegetation seems to be attractive to them and they typically avoid developed areas of any type from urban to agricultural as well as heavily forested regions.
In desolate areas e. However, they are not solely tied to high elevations and can breed in lowlands if the local habitats are suitable.
Below are more detailed description of habitats occupied by golden eagles in both continents where they occur. In the Arctic fringe of Eurasia, golden eagles occur along the edge of the tundra and the taiga from the Kola peninsula to Anadyr in eastern Siberia , nesting in forests and hunting over nearby arctic heathland.
Typical vegetation is stunted, fragmented larch woodland merging into low birch - willow scrub and various heathland.
In the rocky, wet, windy maritime climate of Scotland , Ireland , and western Scandinavia , the golden eagle dwells in mountains. These areas include upland grasslands , blanket bog , and sub-Arctic heaths but also fragmented woodland and woodland edge , including boreal forests.
In Western Europe, golden eagle habitat is dominated by open, rough grassland, heath and bogs, and rocky ridges, spurs, crags , scree , slopes and grand plateaux.
In Sweden , Finland , the Baltic States , Belarus and almost the entire distribution in Russia all the way to the Pacific Ocean , golden eagles occur sparsely in lowland taiga forest.
These areas are dominated by stands of evergreens such as pine , larch and spruce , occasionally supplemented by birch and alder stands in southern Scandinavia and the Baltic States.
This is largely marginal country for golden eagles and they occur where tree cover is thin and abuts open habitat. Golden eagle taiga habitat usually consists of extensive peatland formations caused by poorly drained soils.
In central Europe, golden eagles today occur almost exclusively in the major mountain ranges, such as the Pyrenees , Alps , Carpathians , and the Caucasus.
Here, the species nests near the tree line and hunt subalpine and alpine pastures , grassland and heath above.
Golden eagles also occur in moderately mountainous habitat along the Mediterranean Sea , from the Iberian Peninsula and the Atlas Mountains in Morocco , to Greece , Turkey and Kurdistan.
This area is characterized by low mountains, Mediterranean maquis vegetation , and sub-temperate open woodland. The local pine - oak vegetation, with a variety of Sclerophyllous shrubs are well-adapted to prolonged summer droughts.
From Kurdistan and the southern Caspian Sea to the foothills of the Hindu Kush Mountains in Afghanistan , the typical golden eagle habitat is temperate desert-like mountain ranges surrounded by steppe landscapes interspersed with forest.
Here the climate is colder and more continental than around the Mediterranean. Golden eagles occupy the alpine ranges from the Altai Mountains and the Pamir Mountains to Tibet , in the great Himalayan massif , and Xinjiang , China , where they occupy the Tien Shan range.
In Tibet, golden eagles inhabit high ridges and passes in the Lhasa River watershed , where they regularly joins groups of soaring Himalayan vultures Gyps himalayensis.
The golden eagle occurs in mountains from the Adrar Plateau in Mauritania to northern Yemen and Oman where the desert habitat is largely bereft of vegetation but offers many rocky plateaus to support both the eagles and their prey.
In Israel , their habitat is mainly rocky slopes and wide wadi areas, chiefly in desert and to a lesser extent in semi-desert and Mediterranean climates, extending to open areas.
In Ethiopia's Bale Mountains , where the vegetation is more lush and the climate is clearly less arid than in Northeastern Africa, the golden eagle occupies verdant mountains.
The biomes occupied by golden eagles are roughly concurrent with those of Eurasia. In western and northern Alaska and northern Canada to the Ungava Peninsula in Quebec , the eagles occupy the Arctic fringe of North America the species does not range into the true high Arctic tundra , where open canopy gives way to dwarf-shrub heathland with cottongrass and tussock tundra.
In land-locked areas of the sub-Arctic, golden eagles are by far the largest raptor. From the Alaska Range to Washington and Oregon , it is often found in high mountains above the tree line or on bluffs and cliffs along river valleys below the tree line.
In the foothills of the Rocky Mountains in the United States are plains and prairies where golden eagles are widespread, especially where there's a low human presence.
Here, grassland on low rolling hills and flat plains are typical, interrupted only by cottonwood stands around river valleys and wetlands where the eagles may build their nests.
Golden eagles also occupy the desert-like Great Basin from southern Idaho to northern Arizona and New Mexico.
In this habitat, trees are generally absent other than junipers with vegetation being dominated by sagebrush Artemisia and other low shrub species.
Although the vegetation varies a bit more, similar habitat is occupied by golden eagles in Mexico. The golden eagles here often nest in chaparral and oak woodland, oak savanna and grassland amongst low rolling hill typified by diverse vegetation.
Until , a pair of golden eagles were still known to nest in Maine but they are now believed to be absent as a breeding bird from the Eastern United States.
Though they do regularly nest in the marsh-like peatland of the boreal forest, golden eagles are not generally associated with wetlands and, in fact, they can be found near some of the most arid spots on earth.
In the wintering population of Eastern United States, however, they are often associated with steep river valleys, reservoirs, and marshes in inland areas as well as estuarine marshlands, barrier islands, managed wetlands, sounds, and mouths of major river systems in coastal areas.
These wetlands are attractive due to a dominance of open vegetation, large concentrations of prey, and the general absence of human disturbance. Golden eagles usually hunt during daylight hours, but were recorded hunting from one hour before sunrise to one hour after sunset during the breeding season in southwestern Idaho.
Despite the dramatic ways in which they attain food and interact with raptors of their own and other species, the daily life of golden eagles is often rather uneventful.
Although usually highly solitary outside of the bond between breeding pairs, exceptionally cold weather in winter may cause eagles to put their usual guard down and perch together.
The largest known congregation of golden eagles was observed on an extremely cold winter's night in eastern Idaho when individuals were observed perched closely along a line of 85 power poles.
Most populations of golden eagles are sedentary, but the species is actually a partial migrant. Golden eagles are very hardy species, being well adapted to cold climates, however they cannot abide declining available food sources in the northern stretches of their range.
Further east, conditions are too harsh for even wintering territorial adults. The flat, relatively open landscapes in these regions hold relatively few resident breeding golden eagles.
At Mount Lorette in Alberta , approximately 4, golden eagles may pass during the fall, the largest recorded migration of golden eagles on earth.
Adults who bred in northeastern Hudson Bay area of Canada reached their wintering grounds, which range from central Michigan to southern Pennsylvania to northeastern Alabama , in 26 to 40 days, with arrival dates from November to early December.
In southwestern Canada, they leave their wintering grounds by 6 April to 8 May the mean being 21 April ; in southwestern Idaho, wintering birds leave from 20 March to 13 April mean of 29 March ; and in the Southwestern United States , wintering birds may depart by early March.
Territoriality is believed to be the primary cause of interactions and confrontations between non-paired golden eagles.
Golden eagles maintain some of the largest known home ranges or territories of any bird species but there is much variation of home range size across the range, possibly dictated by food abundance and habitat preference.
The invader often responds by rolling over and presenting talons to the aggressor. Rarely, the two eagles will lock talons and tumble through the air; sometimes fall several revolutions and in some cases even tumble to the ground before releasing their grip.
They then often engage in a similar posture with wings spread wide and oriented toward the threat; sometimes rocking back on tail and even flopping over onto the back with talons extended upward as defense.
Such behavior may be accompanied by wing slap against the threatening intruder. Golden eagles usually mate for life. A breeding pair is formed in a courtship display.
This courtship includes undulating displays by both in the pair, with the male bird picking up a piece of rock or a small stick, and dropping it only to enter into a steep dive and catch it in mid-air, repeating the maneuver 3 or more times.
The female takes a clump of earth and drops and catches it in the same fashion. Their nesting areas are characterized by the extreme regularity of the nest spacing.
Copulation normally lasts 10—20 seconds. Mating seems to occur around 40—46 days before the initial egg-laying. After the first chip is broken off of the egg, there is no activity for around 27 hours.
After this period, the hatching activity accelerates and the shell is broken apart in 35 hours. The chick is completely free in 37 hours. Fledging occurs at 66 to 75 days of age in Idaho and 70 to 81 days in Scotland.
The first attempted flight departure after fledging can be abrupt, with the young jumping off and using a series of short, stiff wing-beats to glide downward or being blown out of nest while wing-flapping.
In Cumbria , young golden eagles were first seen hunting large prey 59 days after fledging. Generally, breeding success seems to be greatest where prey is available in abundance.
Golden eagles are fairly long-living birds in natural conditions. The oldest known wild golden eagle was a bird banded in Sweden which was recovered 32 years later.
Natural sources of mortality are largely reported in anecdotes. On rare occasions, golden eagles have been killed by competing predators or by hunting mammalian carnivores, including the aforementioned wolverine, snow leopard, cougar, brown bear and white-tailed eagle attacks.
Most competitive attacks resulting in death probably occur at the talons of other golden eagles. Nestlings and fledglings are more likely to be killed by another predator than free-flying juveniles and adults.
It has been suspected that golden eagle nests may be predated more frequently by other predators especially birds, which are often the only other large animals that can access a golden eagle nest without the assistance of man-made climbing equipment in areas where golden eagles are regularly disturbed at the nest by humans.
Jeff Watson believed that common raven occasionally eats golden eagle eggs but only in situations where the parent eagles have abandoned their nesting attempt.
There is an account of a golden eagle dying from the quills of a North American porcupine Erethizon dorsatum it had attempted to hunt.
An attempted capture of a great blue heron by a golden eagle resulted in the death of both birds from wounds sustained in the ensuing fight. The protozoan Trichomonas sp.
In December , the US Fish and Wildlife Service proposed allowing wind-turbine electric generation companies to kill golden eagles without penalty, so long as "companies take steps to minimize the losses".
If issued, the permits would last 30 years, six times the current 5-year permits. Mankind has been fascinated by the golden eagle as early as the beginning of recorded history.
Most early-recorded cultures regarded the golden eagle with reverence. It was only after the Industrial Revolution , when sport-hunting became widespread and commercial stock farming became internationally common, that humans started to widely regard golden eagles as a threat to their livelihoods.
This period also brought about the firearm and industrialized poisons, which made it easy for humans to kill the evasive and powerful birds.
At one time, the golden eagle lived in a great majority of temperate Europe , North Asia , North America , North Africa , and Japan.
Although widespread and quite secure in some areas, in many parts of the range golden eagles have experienced sharp population declines and have even been extirpated from some areas.
The number of golden eagles from around the range is estimated to be between , and , while the estimates of breeding pairs are from 60, to , If its taxonomic order is considered, it is the second most wide-ranging species after only the osprey Pandion haliaetus.
