The White Eagle

The White Eagle is the oldest of Poland’s national symbols. It is its emblem, its coat of arms. Its origins are both legendary and historical.

Well over a thousand years ago, the three legendary brothers: Lech, Czech and Ruś, leaders of their Slavic tribes, were wandering in Central Europe looking for a place for permanent settlement. Czech became the founder of the nation and state of the Czechs. Ruś went east and became the founder of the nation and state of the Ruthenians.

Lech went further north. One day, he and his tribe stopped for a rest at the edge of a great forest. Looking around Lech spotted a large white bird, majestically circling overhead.

The bird landed on a nest in a large oak tree. Lech took the presence of the white eagle and its nest to be a good omen. He turned to his Lechitians and said: „Here will be the place of our permanent settlement which we shall call Gniezno (the old Polish word for nest) and the White Eagle shall be our symbol.” The declaration was enthusiastically acclaimed and accepted by all the Lechitians.

The name is significant for Gniezno, today a town of over 70,000 inhabitants some 30 miles east of Poznań, is generally credited with having been Poland’s first capital.

Historically, the employment of the White Eagle as a symbol goes back to the formative period of Polish statehood.

The first crude effigy of the White Eagle, the emblem of the Piast dynasty, is to be found on the silver denarius of Bolesław Chrobry, the first crowned King of Poland. He was the son of Mieszko I, the first historical ruler of the Piast dynasty, who, in 966, had accepted Christianity on behalf of his subjects. The coronation of Bolesław Chrobry in 1025 gave recognition to the Polish state and raised his personal prestige.

The next 200 years was a period during which Poland became divided into various provinces, each ruled individually by dukes of the Piast line. However, the White Eagle, that ancient sign of strength, power, majesty and royalty, was retained by most of them, including the dukes ruling Kraków, as their personal coat of arms. This fact played an important role in the reunification of the divided nation. Also, it was during this period that the White Eagle became refined into the heraldic form we are familiar with today.

An important date in the history of Poland and its White Eagle emblem was June 26, 1295. On that date, Przemysł II, duke of Wielkopolska, assumed the crown of Poland in Gniezno, thus bringing about the reunification of the country. On the day of his coronation, he acquired the seal of majesty. The obverse of the seal shows an image of the King sitting on the throne with the crown upon his head and a globe and a scepter in his hands.

The reverse of the seal bears the Latin inscription, „REDDIDIT IPSE DEUS VICTRICIA SIGNA POLONIS,” that is, „God Himself Restored Polish Signs of Victory,” and a shield with a crowned Eagle on it. The fact that the Eagle is crowned is significant, for up to that time the Piast dynasty Eagles had been uncrowned.

The coronation of King Przemysł II in 1295 not only restored the dignity of the Polish monarchy, but also raised the White Eagle, the King’s personal emblem, to the rank of the Official Coat of Arms of the Kingdom of Poland and dignified it with a golden crown, golden beak, and golden claws. Though this is not evident on the wax seal, we have reason to believe that the Eagle appeared on a field of red. It has retained these characteristics to this day.

The last two Kings of the Piast dynasty, Władysław Łokietek and his son, Kazimierz Wielki, both contributed immensely not only to the rebuilding of the reunified Polish Kingdom, but also to the enrichment of the kingdom’s coat of arms.

In the Royal Castle on the Wawel Hill in Kraków one can see the coronation sword of the Polish Kings, the so called Szczerbiec, first used during Władysław Łokietek’s coronation in 1320. At the top of the blade, just below the handle is affixed a plaquette showing the eagle in a red field, a coat of arms almost identical to that of Przemysł II.

In 1386 a great event occurred in the history of Poland. Władysław Jagiełło, the Grand Duke of Lithuania, accepted Christianity with his people, married Jadwiga, the Queen of Poland, and thereupon was crowned King of Poland. As such he used the White Eagle symbol. A magnificent version of it can be seen in the work of Wit Stwosz, the great artist who sculpted it on the side of the King’s tomb in the Wawel cathedral.

Though King of Poland, Jagiełło remained also Grand Duke of Lithuania and as such he joined the Grand Duchy to Poland by a personal union. This is reflected in the federated country’s coat of arms which Jagiełło quartered placing on it the coats of arms of both nations, repeating each for symmetry. Lithuania’s coat of arms was the Pogoń which is translated into English as „the Pursuit.” It portrays a rider, sword in hand, mounted on a horse. In time the twin nations came to be called Rzeczpospolita Dwóch Narodów, or the Commonwealth of the Two Nations -.

The quartered coat of arms continued to be used by succeeding Kings of the Jagiellonian dynasty. Thereafter Poland’s Kings were elected, but they continued to use the same quartered coat of arms, superimposing in the center of it their personal or family emblem. The White Eagle did not cease to be the symbol of the Kingdom of Poland, but was used chiefly in Poland proper.

Towards the end of the 18th century, Poland lost its independence when it was partitioned in three stages (1772, 1793 and 1795) by Russia, Prussia and Austria. The use of both the White Eagle and the Pursuit was forbidden and these symbols were replaced by the coats of arms of the partitioning monarchs.

However, both national symbols were revived during the insurrections of 1830 and 1863. Also, the White Eagle was the emblem of the Polish Legions, be it in Italy, Hungary or Turkey, that is wherever Poles fought for „Your Freedom and Ours.”

When Poland regained its independence after the First World War, the Sejm, or parliament, in 1919 re instituted the crowned White Eagle as the official state symbol. In 1927, it approved a new version of the design, the one which continues to be in use to this day.

During World War II, the portrayal and use of White Eagle symbol was forbidden by both the German and Russian occupants of Poland. Thus again it became the symbol of the nation’s struggle for independence. It was used by the Polish Underground Army and by the Polish Government and Armed Forces in Exile.

Poland did not regain full sovereignty at the end of World War II. The Soviet Union imposed a Communist Regime on the nation and injudiciously removed the crown from the restored White Eagle emblem, an action that angered the Polish nation and underscored the country’s loss of true sovereignty.

When in 1989, the Solidarity movement caused the downfall of the Communist regime, one of the first acts of the democratically elected Sejm was restoration of the White Eagle’s crown.

The White Eagle, once an emblem the of the absolute power of Kings, over the centuries, changed into a powerful patriotic symbol uniting the citizens of all social classes. Today, the White Eagle appears on the seals of all government agencies, be it national or local, on the buildings that house their offices, in classrooms, on Poland’s currency and coins, on miliary and official banners, on soldiers’ caps and uniform buttons.

The white-tailed eagle (Haliaeetus albicilla) — also called the sea eagle, erne (sometimes ern, ørn), and white-tailed sea-eagle — is a large bird of prey in the family Accipitridae which includes other raptors such as hawks, kites, and harriers. It is considered a close cousin of the bald eagle and occupies the same ecological niche, but in Eurasia.

The white-tailed eagle is a very large bird. It measures 66–94 cm (26–37 in) in length with a 1.78–2.45 m (5.8–8.0 ft) wingspan. The wingspan, with a midpoint of 2.18 m (7.2 ft), is on average the largest of any eagle.[3][4] The Steller’s sea eagle, larger in both weight and total length, is the closest rival for median wingspan amongst living eagles.[3] The bald eagle is roughly the same size as the white-tailed eagle, although has a shorter average wingspan and usually longer total length, due to a longer tail.[3] Females, typically weighing 4–6.9 kg (8.8–15.2 lb), are slightly larger than males, which weigh 3.1–5.4 kg (6.8–11.9 lb)n[3] The record weight for the species was 7.5 kg (17 lb) for a specimen from Scotland, while a more recent huge female from Greenland reportedly spanned 2.53 m (8.3 ft) across the wings.[5][6] Among standard measurements, the wing chord is 55.2–71.7 cm (21.7–28.2 in), the tail is 25–33 cm (9.8–13.0 in), the tarsus is 9.2–10.1 cm (3.6–4.0 in) and the exposed culmen is 6–6.5 cm (2.4–2.6 in).[3][7] Size variation is generally a clinal trend: measurements of eagles from Greenland are in general larger than in other populations of the species, while those from the (now discontinuous) population in the Middle East, at the southern extreme of this species distribution, are the smallest in the species.[3][8] The white-tailed eagle is sometimes considered the fourth largest eagle in the world [9] and is on average the fourth heaviest eagle in the world.[3][10]

This species has broad „barn door” wings, a large head and a large thick beak. The adult is mainly grayish-brown except for the slightly paler head and neck, blackish flight feathers, and distinctive white tail. All bare parts are yellow in color, including both the bill and the legs. In juvenile birds, tail and bill are darker, the tail becoming white with a dark terminal band in sub-adults.[11][page needed] The combination of mousy-brown coloration, broad, evenly held wings, white tail, strong yellow bill and overall large size render the white-tailed eagle essentially unmistakable in its native range.[3]

Some individuals have been found to live over 25 years, 21 years being the average.[9]

This large eagle breeds in northern Europe and northern Asia. The largest population in Europe is found along the coast of Norway. The population in 2008 stood at 9,000–11,000 pairs.[9] They are mostly resident, only the northernmost birds such as the eastern Scandinavian and Siberian population migrating south in winter. Birds from eastern Russia rarely migrate into Alaska.

Small disjunct resident populations occur in southwesternmost Greenland and western Iceland. The former has been proposed as a distinct subspecies, groenlandicus, based on their very large size and body proportions. However, the species is now considered monotypic and the size variation is clinal according to Bergmann’s rule.[13][page needed] A recent genetic study of mitochondrial DNA[14] is consistent with this idea. Greenlandic white-tailed eagles form, on evolutionary time scales, a relatively recently founded population that has not yet accumulated many unique genetic characteristics. However, the population appears to be demographically isolated and deserves special protection.

The white-tailed eagle forms a species pair with the bald eagle. These diverged from other sea eagles at the beginning of the early Miocene (c. 10 mya) at the latest, possibly (if the most ancient fossil record is correctly assigned to this genus) as early as the early or middle Oligocene, about 28 mya.

As in other sea-eagle species pairs, this one consists of a white-headed (the bald eagle) and a tan-headed species. They probably diverged in the North Pacific, spreading westwards into Eurasia and eastwards into North America. Like the third large northern species, Steller’s sea eagle, adults have yellow feet, beaks and eyes.

Currently, eagles only occur in the Hawaiian Islands as vagrants, but Quaternary bones of Haliaeetus have been found on three of the major islands. An ancient DNA study published in 2015 characterized the rapidly evolving mitochondrial control region of one of these specimens. DNA from a ∼3500-year-old sea eagle skeleton found in a lava cave on Maui was sequenced. Phylogenetic analyses suggested that the Hawaiian eagle represents a distinct (>3% divergent) mtDNA lineage that is most closely related to extant white-tailed eagles. Based on fossil calibration, the Hawaiian mtDNA lineage probably diverged around the Middle Pleistocene. Thus, although not clearly differentiated in morphology from its relatives, the Hawaiian eagle likely represented an isolated, resident population in the Hawaiian archipelago for more than 100,000 years, where it was the largest terrestrial predator. The reasons for its extinction are unknown.

The white-tailed eagle’s diet is varied, opportunistic and seasonal. Prey specimens can often include fish, birds and mammals. Many birds live largely as scavengers, regularly pirating food from otters and other birds including cormorants, gulls, ospreys and various other raptors.[3] Carrion is often the primary food source during lean winter months, with fish and ungulates preferred but everything from cetaceans to livestock to even humans being eaten after death.[3][17] Among the scavengers in their range, eagles are often dominant over all but perhaps the largest carnivorous mammals (i.e. gray wolves, etc.)[3] However, this eagle can be a powerful hunter as well. In Scotland, the diet of this species differs significantly from that of sympatric golden eagles, as is also the case in Norway.[3] The daily food requirement for a white-tailed eagle is in range of 500–600 g (1.1–1.3 lb).[18][page needed] Although generally a less active hunter than the golden eagle, competition over food can go either way depending on the individual eagle. They can exist at higher population densities and typically outnumber golden eagles because of their longer gut and more efficient digestive system, being able to live better with less food.

Virtually any fish found near the surface is potential prey for the white-tailed eagle. Commercial fisheries and carp ponds are readily exploited by the eagles when available. Although, given the opportunity, they occasionally kill and harass some land birds, white-tailed eagles usually target water-based birds as prey.[3] In the Baltic, the diet of this species consists mainly of sea birds (from the little tern to the great skua) and pike. Recently they are reported to have attacked and eaten great cormorants and in some cases destroyed whole colonies.[20] In the Estonian island of Hiiumaa, home to at least 25 pair of sea eagles, as many as 26 individuals have been observed simultaneously culling a single cormorant colony. In the UK, fulmar are noted as a common prey species and as such may contribute to locally high levels of DDT and PCB chemicals in nesting eagles.[17] Additionally, loons, grebes, ducks, coots, auks, gulls, geese and even swans have been preyed upon.[3] Adults, nestlings and eggs of other birds are all regularly consumed. When preying upon non-nesting birds, white-tailed eagles often fly towards a waterbird repeatedly, forcing it to dive again and again until the bird is exhausted and more easily caught.[3] Very large prey such as swans may be dragged along the surface of the water to the shore to be consumed.[3] Live mammals consumed have ranged in size from voles to lambs and deer calves, the latter likely around the same size as the record-sized deer carried by bald eagles in North America.[3]

White-tailed eagles are sexually mature at four to five years of age. They pair for life, though if one dies replacement can occur quickly. A bond is formed when a permanent home range is chosen. They have a characteristic aerial courtship display which culminates in the pair locking talons mid-air and whirling earthwards in series of spectacular cartwheels. White-tailed eagles are much more vocal than golden eagles, particularly during the breeding season and especially the male when near the eyrie. Calls can sometimes take the form of a duet between the pair.

The nest is a huge edifice of sticks in a tree or on a coastal cliff. Being faithful to their territories, once they breed, nests are often reused, sometimes for decades by successive generations of birds; one nest in Iceland has been in use for over 150 years.[11][page needed] In Scandinavia, trees have been known to collapse under the weight of enormous, long-established nests.

The territory of the white-tailed eagle ranges between 30 and 70 km2 (12 and 27 sq mi), normally in sheltered coastal locations. Sometimes they are found inland by lakes and along rivers. Territory of white-tailed eagles can overlap with those of the golden eagle but competition between the two species is limited. Golden eagles prefer mountains and moorland, while the white-tailed eagle prefers the coast and the sea. In adulthood, the white-tailed eagle has no natural predators and is thus considered an apex predator.

Mated pairs produce one to three eggs per year, laid two to five days apart in March or April and incubated for 38 days by both parents. Once hatched, chicks are quite tolerant of one another, although the first hatched is often larger and dominates at feeding times. The female does most of the brooding and direct feeding, with the male taking over now and then. Young are able to feed themselves from five to six weeks and they fledge at eleven to twelve weeks, remaining in the vicinity of the nest, dependent on their parents for a further six to ten weeks. The sex of nestlings can be identified using field methods, or using DNA.

Surplus chicks are sometimes removed from nests to use in reintroduction programs in areas where the species has died out. If left in the nest, they often die sooner or later, as with most large eagles. In such programs the birds are raised in boxes on platforms in the tree canopy and fed in such a way that they cannot see the human supplying their food, until they are old enough to fly and thus find their own food.

White-tailed eagles, being apex predators, tend to experience bioaccumulation from environmental pollutants present in their prey; they also suffer intensive persecution by shepherds and gamekeepers who consider them (usually wrongly[19]) a threat to their livestock and gamebirds. During the period 1800-1970, white-tailed eagles in most of Europe underwent dramatic declines and became extinct in many regions of western, central and southern Europe.

A white tailed eagle was shot in the winter of 1857 at Stolford in Bridgwater Bay and subsequently preserved for display. It may be seen at the Somerset Heritage Centre (TA2 6SF). It was presented to the county museum by Miss Bailey, the executrix of the owner’s will, in 1881.

While Norway, Germany, Poland and Iceland harboured the largest surviving populations, pockets of reproducing pairs remained in several other countries.[24] Intense conservation actions throughout much of the remaining European distribution range (legal protection to decrease hunting, protection of breeding sites, and winter feeding) led to recovery of many local populations. Since the 1980s, the European white-tailed eagle population has recovered steadily and is spreading back westward. It has today recolonised several traditional breeding areas in Europe. This ongoing recovery is assisted in Scotland and Ireland by reintroduction schemes.

Some threats still remain, notably illegal persecution by gamebird shooting and egg thieves in Scotland. A new threat from wind turbines is emerging with significant mortality (considerably in excess of the area’s population productivity) occurring at the Smøla Windfarm in Norway.

White-tailed eagles were successfully reintroduced to the Isle of Rum, in the Small Isles archipelago in Scotland, in 1975 and now breeds throughout the Western Isles and the mainland coast of Wester Ross. One of its Gaelic names is ‚iolar súil na gréine’ or ‚eagle of the sunlit eye.’ In August 2008, fifteen chicks raised in Norway were released at a secret location in Fife, in expectation of reintroducing the species to the east coast of Scotland as well. The white-tailed eagle is still a rare breeder in Britain following its extinction and reintroduction, with 36 pairs in 2006 and 40 in 2008.

On 22 May 2006, it was announced that a pair of white-tailed eagles breeding in the Oostvaardersplassen nature reserve in the Netherlands had arrived on their own, not as a reintroduction. This was the first time the bird has bred in the Netherlands in living memory. In 2007, 2008 and 2009 the eagles returned to their nest. In 2010, it turned out that the white-tailed eagle was also breeding in the Zwarte Meer nature district and in the Lauwersmeer area. There is also a confirmed case of breeding white-tailed eagles in the Biesbosch.

The white-tailed eagle is being reintroduced to Ireland, where its Irish name of Iolar Mara (sea eagle) reflects its historic association with the island’s long coast. The program was begun in the summer of 2007. Fifteen to twenty young eagles from Norway are being released each spring into the Killarney National Park in the south-west of Ireland. This comprehensive project will last a number of years, with many more eagles being released. The species has a rich history on the island but became extinct in Ireland in the 1900s due to persecution from landowners. The last pair bred on the coast of Mayo in 1912.

In 2007, a hundred local sheep farmers gathered at Kerry airport to protest the eagles’ arrival. Irish Farming Association Hill Committee chairman Mr O’Leary said he had no doubt the eagles would take lambs. Since their reintroduction seven eagles have been confirmed poisoned in County Kerry, two suspected of having been poisoned, and one shot. A 13th eagle released in Kerry was shot in Northern Ireland. Twenty more eagles were due for release in 2010. However, Dr Allan Mee, in charge of the sea eagle project, stated „the continuing loss of eagles to poisoning had cast a shadow over the future of the ambitious programme.” The first white-tailed eagle breeding pair since 1912 nested 100 years later on Lough Derg (Loch Deirgeirt), marking a great success for the Irish reintroduction programme. In early May 2013, the first eaglets were born in Ireland since the re-introduction programme began; one in the Killarney National Park and two in County Clare. In Spring 2015, five nests hatched chicks in 4 counties in Ireland – Clare, Cork, Galway and Kerry.

Studies of microsatellite and mitochondrial DNA in white-tailed eagles from north-central Europe have shown that the recovering European population has retained appreciable amounts of genetic diversity, implying low risk of inbreeding depression (a serious concern in species with low population density). Therefore, recovery of this formerly endangered species is a true success story for nature conservation. The story also shows how local protection of a species can be successful and important for preserving the species’ evolutionary potential.

The white-tailed eagle is the national bird of Germany and appears in the German coat of arms.[citation needed] It is believed to be the White eagle shown in the Polish coat of arms and in the Serbian coat of arms. The sea eagle is often blazoned grasping a fish (usually a pike) in its talons, distinguishing it from an ordinary eagle.

On Orkney, (Scotland), sea eagle bones have been found in 6000-year-old burial mounds, suggesting that the birds were revered by the prehistoric people there, a belief strengthened by the Pictish stone carvings of sea eagles from Orkney.

Cut marks have been found in white-tailed eagle talons in Krapina, suggesting Neanderthals’ use of jewelry.

In the Shetland Isles (Scotland), fishermen believed that as soon as a sea eagle appeared fish would rise to the surface, belly up; this led to some fishermen using eagle fat, smeared on their bait, to increase their catch.
