; Berlanga, H.; Blancher, P.J. Short- to medium-distance migrant. [73] In Western Norway, most recorded undulating flight displays occur during the pre-laying period in late winter/early spring. 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]. [3], The biomes occupied by golden eagles are roughly concurrent with those of Eurasia. Golden eagles also occupy the desert-like Great Basin from southern Idaho to northern Arizona and New Mexico. Most early-recorded cultures regarded the golden eagle with reverence. [65] Golden eagles occupy the mountains and coastal areas of California and Baja California in Mexico where hot, dry summers and moist winters are typical. Aquila chrysaetos This magnificent bird is widespread in the wilder country of North America, Europe, and Asia. [67][68] In Eastern North America, the species still breeds on the Gaspe Peninsula, Quebec. Eagles raised at latitudes greater than 60° N are usually migratory, though a short migration may be untaken by those who breed or hatch at about 50° N.[76] During migration, they often use soaring-gliding flight, rather than powered flight. Individuals of any of the subspecies are somewhat variable and the differences between the subspecies are clinal, especially in terms of body size. Here the climate is colder and more continental than around the Mediterranean. [3] After hatching, 80% of food items and 90% of food biomass is captured and brought to the nest by the adult male. [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). [11], This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Falco chrysaetos. Lustrous gold feathers gleam on the back of its head and neck; a powerful beak and talons advertise its hunting prowess. Moulting usually decreases in winter. 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. Launch Earth. The type locality was given simply as "Europa"; it was later fixed to Sweden. Dunstan, T. C., Harper, J.H. The oldest known wild golden eagle was a bird banded in Sweden which was recovered 32 years later. Click here to return to the species description page . 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). kamtschatica). [4], 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. [92], Golden eagles usually mate for life. Hawks, Eagles, and Kites(Order: Accipitriformes, Family:Accipitridae). [6] Steppe eagles can also approach golden eagles in size but are more compact and smaller headed with little colour variation to their dark earth-brown plumage, apart from juvenile birds which have distinctive cream-coloured bands running through their coverts and secondaries. 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. Explore Birds of the World to learn more. These areas include upland grasslands, blanket bog, and sub-Arctic heaths but also fragmented woodland and woodland edge, including boreal forests. [3][21] Rarely, juvenile birds may have only traces of white on the tail. [26] A typical, unhurried soaring speed in golden eagles is around 45–52 kilometres per hour (28–32 mph). [4][114] On a global scale, the golden eagle is not considered threatened by the IUCN.[2]. 75 to 85 days after fledging, the young were largely independent of parents. These majestic birds range from Mexico through much of western North America as far north as Alaska; they also appear in the east but are uncommon. They are found at low density in remote areas of the Scottish Highlands and most of the Hebrides. [95] The longest-lived known captive golden eagle, a specimen in Europe, survived to 46 years of age. Northern breeders (in Alaska and Canada) migrate up to thousands of miles to wintering grounds; southern pairs tend to be resident year-round. Juveniles of less than 12 months of age tend to have the most white in their plumage. Golden Eagle Attacks and Catches Deer. [77] Similarly the entire population of golden eagles from northern and central Alaska and northern Canada migrates south. [104] Of natural sources of death, starvation is probably under-reported. This period also brought about the firearm and industrialized poisons, which made it easy for humans to kill the evasive and powerful birds. Golden eagle taiga habitat usually consists of extensive peatland formations caused by poorly drained soils. [3] Survival rates are usually much lower in juvenile eagles than in adult eagles. [61] From east of the Canadian Rocky Mountains to the mountains of Labrador, the golden eagle is found in small numbers in boreal forest peatlands and similar mixed woodland areas. [107] Several further diseases that contribute to golden eagle deaths have been examined in Japan. Despite being extirpated from or uncommon in some of its former range, the species is still widespread, being present in sizeable stretches of Eurasia, North America, and parts of North Africa. Roll the dice to discover someplace new, take a guided tour with Voyager, and create your own maps and stories. [6] Most known vocalisations seem to function as contact calls between eagles, sometimes adults to their offspring, occasionally territorial birds to intruders and rarely between a breeding pair. They are best suited to hunting in open or semi-open areas and search them out year-around. [108] A captive eagle died from two malignant tumors – one in the liver and one in the kidney. This area is characterized by low mountains, Mediterranean maquis vegetation, and sub-temperate open woodland. Juvenile golden eagles can have large patches of white on their wings and tail that are quite different from the random, sometimes large and splotchy-looking distribution of white typical of juvenile Haliaeetus. [25] Most displays by mature golden eagles (67% for males and 76% for females) occur, rather than around the nest, at the edge of their home ranges. [3] In Israel and Scotland, aggressive encounters peaked from winter until just before egg-laying and were less common during the nesting season. [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. 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. [31] Compared to Haliaeetus eagles, the golden eagle has wings that are only somewhat more slender but are more hawk-like and lack the flat, plank-like wing positioning seen in the other genus. [106] Avian cholera caused by bacteria (Pasteurella multocida) infects eagles that eat waterfowl that have died from the disease. The genus Aquila is distributed across every continent but for South America and Antarctica. The voice of the golden eagle is considered weak, high, and shrill, has been called "quite pathetic" and "puppy-like", and seems incongruous with the formidable size and nature of the species. 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. gurneyi) and the wedge-tailed eagle (clearly part of an Australasian radiation of the lineage). After this period, the hatching activity accelerates and the shell is broken apart in 35 hours. Although the vegetation varies a bit more, similar habitat is occupied by golden eagles in Mexico. Arroyo, B., Ferreiro, E. & Garza, V. (1990). Although less agile and manoeuvrable, the golden eagle is apparently quite the equal and possibly even the superior of the peregrine falcon's stooping and gliding speeds. The number of golden eagles from around the range is estimated to be between 170,000 and 250,000 while the estimates of breeding pairs are from 60,000 to 100,000.
