Song or voice of the Golden Eagle

It is generally a silent species, although it can give a thin, flute-like whistle, both in flight and when perched.

Flight of the Golden Eagle

Its very well-proportioned silhouette is defined by long, broad wings with a very rounded trailing edge and a striking narrowing at the armpit, and a long tail. Seen in flight, at a distance it looks very dark, with the flight feathers and tail slightly paler.

  1. It climbs in circles with long, broad wings, with a very rounded trailing edge and a striking narrowing at the armpit, and the long tail.

  2. It quarters the broken terrain in search of rabbits, hares, pigeons and partridges. From a distance it looks very dark, with the flight feathers and tail somewhat paler.

  3. When it spots prey, it drops down and catches it; it also makes use of carrion. It is a silent species, which sometimes gives a thin, fluty whistle.

Identification of the Golden Eagle

It is a large bird of prey and the biggest of the Iberian eagles. The adult has an overall very dark brown colouring, with more golden tones on the leading edge of the wings, the nape and the neck. Seen in flight, at a distance it looks very dark, with the flight feathers and tail slightly paler.

Its very well-proportioned silhouette is defined by long, broad wings with a very rounded trailing edge, with a striking narrowing at the armpit, and a long tail. The young bird of the year is very dark, almost black, and in flight a white patch on each wing stands out, together with a broad white area over much of the tail, ending in a black terminal band. Through successive moults this strongly contrasting pattern fades, until the definitive adult plumage is reached at five or six years of age.

Habitat and distribution of the Golden Eagle

It is distributed across the whole northern hemisphere, through Eurasia and North America, with some populations in North Africa and as far south as Ethiopia. It has several subspecies.

In Spain it occupies much of the country, but is absent from the Canaries and the Balearic Islands and from large regions of the Peninsula: Mediterranean coastal areas, the Guadalquivir valley, southern Extremadura, the northern plateau, the Cantabrian coastal strip and almost all of Galicia. It is not found in Ceuta or Melilla either. The most extensive and continuous breeding populations are in the group formed by the Pyrenees–Pre-Pyrenees, the Ebro depression and the Iberian System, in the north-east of the peninsula, and in the Betic ranges, Sierra Morena and the Montes de Toledo, in the southern quadrant. The two subspecies in Spain are «chrysaetos», in the Pyrenean area, and «homeyeri», in the rest of the Peninsula.

It is associated mainly with mountain areas or sierras of rugged relief, with rocky cliffs and crags to nest on, although occasionally it can nest in very large trees. It occupies a great variety of habitats, as long as there is broken terrain and quiet areas to breed.

On the Peninsula it is resident: breeding birds are sedentary, while young and immature birds make dispersive movements.

Etymology of the Golden Eagle

«Aquila» is the Latin word for «eagle», which perhaps derives from «aquilus», «dark-coloured». «Chrysaetos» is the ancient Greek name for the golden eagle and comes from «khrysós», «gold», and «aetós», «eagle»: the golden eagle, for the tones of the nape.

Population of the Golden Eagle

In the 2021 European Red List of Birds the European breeding population is estimated at between 19,200 and 25,600 mature individuals, with an increasing trend. Spain holds one of the most numerous populations on the continent, and with recent increases in most of its range it could approach 2,000 pairs in 2021. To this is added a non-breeding population of between 2,500 and 3,000 individuals, so the total Spanish population could be put at a minimum of 6,000 to 6,830 individuals. Threats include habitat loss to infrastructure, public works and housing developments; shooting and poisoning on hunting estates; nest robbing or destruction; and electrocution on power lines. Even so, its expansion is being helped by a change in human attitudes, and newly formed pairs are starting to nest in habitats more altered by people than those of the classic pairs.

Nest of the Golden Eagle

The nest is generally located on crags (in 90 % of cases), between 200 and 2,200 metres above sea level; 10 % of pairs, and up to 40 % in areas short of cliffs and rich in food, such as the Ebro valley, put it in trees, above all pines, holm oaks and cork oaks. It is a solid structure of branches, lined with grasses and even wool, which can reach 2 metres high and up to 1.5 metres across; nests in trees are usually bigger. Both parents build it over about four to eight weeks, although the female does most of the work. Each pair usually has several nests in its territory, which it reuses periodically.

Courtship and breeding of the Golden Eagle

The breeding cycle begins at the end of January with the courtship display. Laying takes place from the end of February to the end of March and consists of one to three matt white eggs with reddish-brown spots. Incubation is by the female alone and lasts 41–45 days. The chicks are cared for by both parents and watched continuously by the female, with some help from the male, until 14 days; both adults feed them until they are 30 days old, and from then on they feed themselves. Depending on the supply of prey, there may be facultative siblicide. The plumage develops fully in about 67–80 days, and after leaving the nest the young stay tied to the adults about three months more before dispersing.

Diet of the Golden Eagle

Its very varied diet includes mammals (above all rabbits and hares), birds (pigeons and partridges above all, but also other species) and reptiles (lizards and snakes). It also eats carrion.

Curious facts about the Golden Eagle

The Golden Eagle is the mightiest of our eagles and one of the most widespread birds of prey in the world. The young bird is almost black, with white patches that disappear with moults, and does not reach adult plumage until five or six years. In Sweden the ring number of a bird of more than 36 years was read.

The Golden Eagle in Cabañeros

This website’s page on sclerophyllous woodland lists it among the raptors of the vegetated sierras of Cabañeros, together with the Spanish Imperial Eagle, the Booted Eagle, the Cinereous Vulture and the Short-toed Snake Eagle, which is a summer visitor. SEO/BirdLife also shares a video recorded in Cabañeros National Park, «Golden Eagle attacking a stork».

How to tell them apart

They are similar in appearance1. The Imperial has a very dark brown tone, with whitish shoulders and pale nape and sides of the head; its wings are long and relatively rectangular, and the tail long but not as long as in the Golden Eagle, and somewhat narrow.
