Golden Eagle Description. 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. 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. Aspects in the ecology and biodynamics of the Golden Eagle (. Copulation normally lasts 10–20 seconds. Lustrous gold feathers gleam on the back of its head and neck; a powerful beak and talons advertise its hunting prowess. [74] Golden eagles are believed to sleep through much of the night. 11 of 16 dead juvenile eagles which had hatched in Denali National Park had died of starvation. 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. [31] Confusion is most likely between juvenile Haliaeetus and golden eagles, as the adult golden has a more solidly golden-brown coloration and all Haliaeetus eagles have obvious distinctive plumages as adults. Hunt, W. G., Jackman, R.E. [4] More surprisingly, the smaller, much paler-bellied sister species Bonelli's eagle (A. fasciatus) and African hawk-eagle (A. spilogaster), previously included in the genus Hieraaetus, have been revealed to be genetically much closer to the Verreaux's and golden eagle lineage than to other species traditionally included in the genus Aquila. [4][28] This makes the golden eagle one of the two fastest living animals. Typical vegetation is stunted, fragmented larch woodland merging into low birch-willow scrub and various heathland. Golden Eagles migrate during the day. [78] Birds hatched in Denali National Park in Alaska traveled from 818 to 4,815 km (508 to 2,992 mi) to their winter ranges in western North America. Rich, T.D. [9] Occasionally, juvenile eagles have white patches on the remiges at the bases of the inner primaries and the outer secondaries, forming a crescent marking on the wings which tends to be divided by darker feathers. Departure from northern breeding areas coincides with the first lasting snowfall, freeze-up, north winds, or decreasing prey abundance. [4][19] The bill is dark at the tip, fading to a lighter horn colour, with a yellow cere. [99] The average life expectancy of golden eagles in Germany is 13 years, extrapolated from a reported mere 92.5% survival rate. The turkey vulture can be distinguished by its less controlled, forceful flying style (they frequently rock back and forth unsteadily in even moderate winds) and its smaller, thinner body, much smaller head and, at closer range, its slaty black-brown colour and silvery wing secondaries. [109], In December 2016, 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". [62][63][64] However, golden eagles are typically absent in North America from true deserts, like the Sonora Desert, where annual precipitation is less than 20 cm (7.9 in). It is the largest and least populous of the five species of true accipitrid to occur as a breeding species in both the Palearctic and the Nearctic.[4]. [83] However, some home ranges have been much smaller, such as in southwestern Idaho where, possibly due to an abundance of jackrabbits, home ranges as small as 4.85 km2 (1.87 sq mi) are maintained. [citation needed] In these mountain ranges, the species often lives at very high elevations, living above tree line at more than 2,500 m (8,200 ft), often nesting in rocky scree and hunting in adjacent meadows. 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 largest known congregation of golden eagles was observed on an extremely cold winter's night in eastern Idaho when 124 individuals were observed perched closely along a line of 85 power poles. 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 central Europe, golden eagles today occur almost exclusively in the major mountain ranges, such as the Pyrenees, Alps, Carpathians, and the Caucasus. Mankind has been fascinated by the golden eagle as early as the beginning of recorded history. [63] The smallest known home ranges on record for golden eagles are in the Bale Mountains of Ethiopia, where they range from 1.5 to 9 km2 (0.58 to 3.47 sq mi). Himalayan Golden Eagle (, "The Quaternary avifauna of. Included in this group are all species described as "hawk eagles" including the genera Spizaetus and Nisaetus, as well as assorted monotypical genera such as Oroaetus, Lophaetus, Stephanoaetus, Polemaetus, Lophotriorchis and Ictinaetus. The local pine-oak vegetation, with a variety of Sclerophyllous shrubs are well-adapted to prolonged summer droughts. 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. 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.
