HABITAT AND GEOGRAPHICAL DISTRIBUTION

The golden eagle, the lady of the skies, whose scientific name is Aquila chrysaetos of the familyAccipitridae, it is found throughout the northern hemisphere especially in the mountain areas. In particular, we find it in the north and west of the United States, in eastern Canada, in the mountainous areas of Europe, in northern and central Asia and also in northern Africa.

It generally does not like wooded areas and lives above the treetops and below the perennial snows at an altitude between sea level and 3600 m. It does not like populated places, nor the plains or prairies as they do not offer places where it can be stationed to locate its prey.

CHARACTER, BEHAVIOR AND SOCIAL LIFE

The type of territory in which it lives is closely related to its habits, in fact the golden eagle must always have the possibility to control the whole situation from an elevated position, without having to get up in flight.

The male and female of the golden eagle are monogamous and can maintain pair bonds for many years, especially in non-migratory pairs. For migratory couples, that is to say those who move from colder areas to warmer areas according to the seasons, there are no precise indications on the maintenance of the couple bond.

It has been observed that golden eagles can live in groups even if they are not necessarily pairs, this seems to be dictated either by the presence of particularly abundant food in the area or by particularly harsh climatic conditions.

In the territory of a pair of golden eagles there can also be 12 nests built by them and among these the couple chooses one every spring to give birth to the young.

The nest is usually built between the branches of a tree or in the spikes of rock and is built in collaboration by the male and the female. It can measure up to a meter in diameter and if the couple decides to settle on a pre-existing nest, they renew it. It can take 4 to 6 weeks to build a nest.

The nest is built with whatever material is available in the area and is then lined with soft vegetation such as shredded plants, grass, dry leaves, green leaves, mosses and lichens.

It also happens that other pairs of eagles can continue to use the nests left by other eagles, making it grow larger and larger up to two meters in diameter and more.

Not much is known about the eagle's domination of the territory. The eagle has been seen to make extraordinary evolutions in the sky, along the border areas that are thought to be made to keep other eagles away.

PHYSICAL CHARACTERISTICS

In the golden eagle the males and females are physically equal to each other except that the females are larger.

They have the body covered with dark brown feathers, with powerful and large wings with an opening of 1,85 - 2,5 m (greater in females) and with the ends that look like fingers used to regulate the flow of air. allowing the eagle to fly even slowly without stalling.

It has powerful muscles that allow it to carry up to 36 kg in flight and fly at a speed of 80 km / h (the average is 28-32 km / h) and even when it is in a dive touch peaks of 200 km / h .

The main feature of this extraordinary bird of prey is the sight: two large brown eyes, directed frontally that allow the eagle to have a binocular sight, like the human one but considerably superior thanks to the fact that the cells responsible for registering color and movement are placed in the back of the eye thus allowing you to have a much sharper vision.

Another peculiarity are the yellow legs provided with powerful black claws formed by a curved rear claw which is the most powerful and by three other claws placed frontally. The beak is also an extraordinary hard and powerful offensive element.

COMMUNICATION

The golden eagles communicate vocally mainly when they are in the reproductive period while it seems that they do not use vocalizations to signal their territory which instead is carried out with wavy flights carried out along the borders.

EATING HABITS

The diet of the golden eagle is very varied depending on the territory and therefore on food availability. The preferred preys are small and medium-sized mammals (rabbits, hares, squirrels, marmots, prairie dogs) but they do not disdain other birds (partridges, pheasants), reptiles, fish. Sometimes they also catch fairly large prey such as cranes, geese, coyotes and badgers.

The hunting technique is as follows: the golden eagle sees its prey either from a high position or while flying over the area. At that point it dives or glides (depending on the mobility of the prey) and grabs it with its claws. If we are talking about birds, they can also be caught in flight.

Generally the eagle tends to eat its prey on the spot but if it has young to feed, it brings the prey to the nest.

The pair of eagles can also hunt together and in this case the technique is the following: one of the two stana and exhausts the prey while the other grabs it.

If the prey is scarce as can happen in the winter period, the golden eagle can also feed on carrion.

REPRODUCTION AND GROWTH OF CHILDREN

The period in which the mating takes place is from March to August depending on the geographical location. For sedentary couples who do not migrate, the construction of the nest and the courtship can begin as early as December while for the migratory species the formation of the couple, the courtship and the construction of the nest begin when the eagles return to their breeding places between February. and mid-April.

Mating is preceded by the "sky dance" which is done by two eagles as a mating ritual. These are beautiful stunts where you can even see the female flying with her belly facing up and the male swooping down on her. The actual mating takes place on earth.

Usually the female lays from 1 to 4 eggs (more frequently 2) each at intervals of 2-5 days. The eggs are almost always hatched by the female and the male is often absent during this period.

When after about 35-45 days (on average 43) the eggs hatch, the male begins to bring food to the nest for the female and the young. Obviously the first chick born will have grown when the others are born and if food is scarce it can be killed by its brother.

The chicks start flying after two and a half months of age and when they have reached about four months they leave the nest and even the parental territory for good and at that point they become nomadic and wander until they are old enough to procreate which will happen when they will have reached 4-5 years, after they will have adult plumage. During this whole period they travel enormous distances, even thousands of kilometers.

PREDATION

Adult golden eagles have virtually no predators. Only chicks can be preyed upon.

STATE OF THE POPULATION

The golden eagle is classified on the IUNC Red list among animals at low risk of extinction Least Concern (LC): a stable population of around 250,000 has been estimated.

The causes of unnatural death for this species are numerous: being electrocuted in the high voltage electric wires; being trapped in traps set up for coyotes or dying from poisoning thanks to the bait set up by breeders to protect their flock.

Today the golden eagle is a protected species in many states.

SOCIAL, ECONOMIC AND ECOSYSTEM IMPORTANCE

The golden eagle often enters into food competition with other species of birds of prey such as bald eagles, white-tailed eagles, condors and also with more common birds such as ravens and peregrine falcons.

From an economic point of view, the eagle has unfortunately always been seen as a damage to the economy and in the past it was often persecuted especially by breeders because it killed some head of cattle.

CURIOSITY'

The golden eagle's feathers are much heavier than its entire skeleton.

The largest nest that was found measured 6.1m high and 2.59m wide.

Golden eagle

The golden eagle (Aquila chrysaetos) is one of the best-known birds of prey in the Northern Hemisphere. It is the most widely distributed species of eagle. Like all eagles, it belongs to the family Accipitridae. These birds are dark brown, with lighter golden-brown plumage on their napes. Immature eagles of this species typically have white on the tail and often have white markings on the wings. Golden eagles use their agility and speed combined with powerful feet and massive, sharp talons to snatch up a variety of prey, mainly hares, rabbits, and marmots and other ground squirrels. [3] Golden eagles maintain home ranges or territories that may be as large as 200 km 2 (77 sq mi). They build large nests in cliffs and other high places to which they may return for several breeding years. Most breeding activities take place in the spring they are monogamous and may remain together for several years or possibly for life. Females lay up to four eggs, and then incubate them for six weeks. Typically, one or two young survive to fledge in about three months. These juvenile golden eagles usually attain full independence in the fall, after which they wander widely until establishing a territory for themselves in four to five years.

Once widespread across the Holarctic, it has disappeared from many areas which are now more heavily populated by humans. 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. 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]

For centuries, this species has been one of the most highly regarded birds used in falconry. Due to its hunting prowess, the golden eagle is regarded with great mystic reverence in some ancient, tribal cultures. It is one of the most extensively studied species of raptor in the world in some parts of its range, such as the Western United States and the Western Palearctic.


Index

En la actualidad, Occidental Europe only houses poblaciones estables en Escocia, Noruega, los Alpes, Italy and the peninsula ibérica, aunque en 2001 se liberaron 35 ejemplares en Ireland (whence the especie se extinguió a comienzos del siglo XX). En Norteamérica se observa también un declive de la especie, aunque mucho menos acusado que en Europe, y en el rest de su distribución permanece estable. El águila real is one of the aves most used in cetrería, especially in Asia Central, whence it is used including para cazar antílopes. [quotes requerida]

Due a su gran capacidad de adaptación al medio, alimentándose de carroña in case necessary (no es difícil observarla en vertederos en inviernos duros), el águila real has achieved maintaining a saludable población, lo que su pariente próxima, la imperial, muy dependiente del conejo, no has achieved in España. En España es un ave no amenazada, with a population estimate en more than 1500 parejas. [quotes requerida]

Al igual que en la mayoría de las aves de prese, las hembras son mayores que los machos, pudiendo llegar al metro de longitud desde el pico a la cola y los 2,3 meters de envergadura alar, y un peso de entre 4 y 6 , 75 kg, mientras que el macho, de un tamaño menor, alcanza between 1,8 y 2 meters de envergadura alar y un peso de entre 2,9 y 4,5 kg. [quotes requerida]

El plumaje es castaño oscuro, tornándose dorado en cabeza y cuello, y blanco en los hombros y en el extremo de la cola. En los individos jóvenes, el blanco abunda más en la cola que el pardo, relación que se send with the edad. Esta especie se incluye in de las llamadas águilas calzadas, ya que las patas están cubiertas de plumaje en lugar de tener una cubierta escamosa como en otras águilas.

Both el águila calva as la real cazan desde el aire, y para achieving it están equipadas con las armas típicas de su familia: fuertes patas terminadas en garras bien desarrolladas, pico ganchudo, gran fuerza y ​​velocidad, y a powerful view capaz de localizar la socket a cientos de metros de distancia. Sus presas son de todos los tamaños y formas: ratones, conejos, liebres, marmotas, zorros, serpientes, and including crías e individuos viejos or enfermos de cabras salvajes, ciervos, jabalíes y rebecos, y aves voladoras y terrestres.

Las águilas reales son monógamas (se suelen emparejar de por vida). Construyen varios nidos en on the territory, which alternan fall año, de estructura muy sencilla. The base of the nidos se construye with three gruesas ramas sobre las que se acondiciona el nest, properly dicho, de palos y ramas menos gruesas. Según las zonas, anidan en árboles altos or bien en rocas escarpadas y acantilados. Cada nueva temporada de cría if the nuevos pisos de ramas añaden to the nest, for it is not rare that alcance el meter and medium of height and dos of diámetro tras varios años de use. [quotes requerida]

The period of reproduction varies from a zone to another between enero y March, y puede desarrollarse en la misma zone donde habitan las águilas during the rest of the year or en otra a la que the pareja emigrates expresamente para reproducirse. Tras el apareamiento the hembra places one or two huevos that incubate during 45 days hasta que salen los polluelos recubiertos por complete de plumón blanco. En los casos en que hay dos pollos en el nest, only one, el que breaks el huevo primero, llega to realizar su primer vuelo hacia los 50 días de vida. El hermano más joven y débil muere antes, desatendido por sus padres or directly expulsado por el más fuerte. [quotes requerida]

Los jóvenes are alimentados por sus padres en el nest hasta que se independizan. Pueden recibir el mismo food que ingieren los adults, aunque con frecuencia los padres cazan más aves para sus hijos que mamíferos. Esto se debe probablemente a que los pájaros son digeridos mejor por los pequeños. [quotes requerida]

Según las clasificaciones, se diferencian seis subespecies de águila real, que difieren en ciertos aspectos de su apariencia or behavior (como por ejemplo, su migratory or sedentary character): [4]

  • Aquila chrysaetos daphanea: Asia central, whence you know them as well Berkut
  • Aquila chrysaetos japonica: Korea and Japan
  • Aquila chrysaetos kamtschatica: Eastern Siberia, occasionally englobed in the sub-species A. c. chrysaetos
  • Aquila chrysaetos canadensis: América del Norte has the peninsula of Baja California and the desierto de Sonora
  • Aquila chrysaetos simurgh: Subspecie extinta de gran tamaño that habitó during el Pleistoceno and el Holoceno inicial en la isla de Creta. [6] Simurgh es uno de los nombres del Ruc, a mitological avenue so large that follows the leyenda podía llevar an elephant on a nest to devour it. Dado que en la misma isla y en la misma época existía a especie de elefante diminuto, es probable que la observación de esta ave cazando crías or jóvenes del proboscidio en la antigüedad hubiese originado el mito.

En la Antigüedad, el águila real was el símbolo del valor y el poder debido a su fuerza, tamaño and inaccesibilidad de sus nidos. En la mythology griega y romana se convirtió ready in one of the símbolos de Zeus / Júpiter, el rey de los dioses, y sustituyó rápidamente al quebrantahuesos as cabeza y garras del temible grifo. En la Antigua Roma pasó de ser a religious symbol to a militar y político, as an emblem of the Empire. Cada vez que una legión romana se ponía en marcha, un soldado en concret, el aquiliferous, marchaba al frente carrying el estandarte coronado with las siglas SPQR y el águila real.

De Roma el águila pasó como símbolo to Bizancio, whence se convirtió en bicéfala. Una de las cabezas representaba al viejo imperio caído de Roma, y ​​la otra al nuevo imperio de Constantinopla. When Charlemagne restored the Imperio de Occidente or Holy Roman Empire of Germany, this también adoptó as símbolo el águila real bicéfala, therefore in the Edad Moderna los Habsburgo prefirieron replace it por el águila imperial. During the Edad Media y Moderna, muchas casas nobiliarias adoptaron también el águila real as emblem, muchas veces flanqueando el escudo de armas de la familia. En la actualidad, Alemania has wanted to acoger al águila real en su escudo en lugar del águila imperial.

A la caída de Constantinopla in 1453, varies casas reales de Europa oriental adoptaron el águila real Byzantine as emblem, with el fin de consagrarse as los herederos of the recién caído Roman Empire of the East. Por esta razón, the Byzantine águila was the emblem of the Rusian Empire, and included hoy en día aparece en el centro de la bandera de Albania.

El águila monocéfala was used as an emblem for Napoleon during the primer Imperio Francés. Antes de eso, the idea was copied from también por los padres de la independencia de Estados Unidos, aunque con el fin de hacer ver la llegada de un nuevo American Empire el águila real fue sustituida por el águila de cabeza blanca, endémica de América del Norte.

El águila de la bandera de México, in exchange, no holds nada que ver with las insignias imperiales europeas, until with the leyenda de la fundación de Tenochtitlán en 1325. Ciudad y capital de los mexicas, y por ello no aparece en pose heráldica sino devouring a snake, however on use comenzó siguiendo the European tradition.

It is the national symbol of Mexico, because it represents it in the shield and the bandera de dicho país. De acuerdo a la leyenda del imperio Aztec, en el lugar en donde encontraran a un águila real sobre un nopal se construiría the capital of the Aztec Empire: Tenochtitlán, hoy la actual Ciudad de México.

En la Iglesia católica, el águila real es el símbolo del apóstol más joven, San Juan. When the Pope Alejandro VI granted the title of Reyes Católicos to the monarcas de España in 1496, he también les authorizó añadir a su escudo el águila de San Juan. El ave permanecido en el escudo español during distinctive periodos de la historia de España, el último de las cuales fue during el Franquismo. La Ley Orgánica 33 de 1981 suprimió el águila real del escudo nacional.

Por último, en algunos países islámicos as Egipto and Irak if he acostumbrado a incluir la llamada águila de Saladin, emblem used by the sultan Saladin during the época de las cruzadas. El símbolo suele estar associated with the pan-Arab movement, ya que al igual que este ambiciona, Saladin retornó Jerusalén a manos de los musulmanes y unificó Oriente Próximo en un solo estado bajo su mando.

Aquila chrysaetos - Golden eagle

Identificação
In águia-real it is practically inconfundível, apenas podendo ser difícil a sua distinção
from rare águia-imperial-ibérica maize. As asas são grandes and largas and a cauda
proportionally comprida, com a cabeça projectada, exibindo a tonalidade pálida
from the nape, que pode ir do castanho claro ao dourado quase branco. No remaining from
plumagem, or tom dos adultos é no geral escuro, ao contrário dos juvenis e
imaturos, que exibem “janelas” brancas nas asas and uma broad branch band na
cauda, ​​bastante visíveis à distância. A great envergadura desta espécie só é
ultrapassada pelas do grifo and do abutre-preto.

Abundância and calendário
Como espécie ameaçada que é, in águia-real é rara e de distribuição muito
localizada, almost exclusively restricting from a or interior do território,
se sobretudo nos vales encaixados and pouco acessíveis. Occurs during todo or anus,
sendo mais fácil a sua observação no início da Primavera, when efectua as
paradas nupciais.

O northeastern is, sem dúvida, a zone where it is corn fácil encontrar esta grande
águia.


Aquila chrysaetos - Golden eagle

The golden eagle is a diurnal bird of prey with a wingspan of 180-230 cm and a weight of 2900-6400 g. The diet typically specializes in medium-sized mammals and birds. In the Alps, the diet is generally based on Marmots in spring-summer and on carcasses of ungulates, which died mainly due to avalanches, in winter. In Europe, the Golden Eagle is classified as a conservation priority species (SPEC 3, rare, Tucker and Heath, 1994). The Alpine population has recently recovered from centuries of relentless persecution and is currently stable or growing slightly. The Trentino population is made up of about forty couples and is also stable. The disturbance at the nest and the abandonment of the mountain with consequent reforestation of many pastures and open vegetation areas, the main hunting areas of the eagle, are however long-term risk factors for the population (Pedrini and Sergio, 2001a, b, c). In Trentino, the golden eagle is strongly linked to high altitude alpine prairie environments, where it hunts its favorite prey, the Marmot, during its breeding season (Pedrini and Sergio, 2001a). The nests are usually placed on a rocky wall, rarely on tall trees.
