It lies between
490-483: A buff colouration. In worn or bleached plumages these light areas can be even paler at times, ranging to almost whitish, which can render a resemblance in such eagles to a washed-out bald eagle. Some of the palest birds can appear anywhere from cream-tawny to light greyish. It is thought that in some populations perhaps paleness increases with age, although it is possible that there is an historical genetic factor to these pale variations. In contrast, some adults can also be
735-467: A schwa . The Middle Dutch dialect areas were affected by political boundaries. The sphere of political influence of a certain ruler often also created a sphere of linguistic influence, with the language within the area becoming more homogenous. Following the contemporary political divisions they are in order of importance: A process of standardisation started in the Middle Ages , especially under
980-607: A species pair with the bald eagle ( Haliaeetus leucocephalus ), which occupies a similar niche in North America. The first formal description of the white-tailed eagle was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Falco albicilla . The genus Haliaeetus was introduced in 1809 by the French naturalist Marie Jules César Savigny in
1225-490: A Dutch exonym for the various German dialects used in neighboring German states. Use of Nederduytsch was popular in the 16th century but ultimately lost out over Nederlands during the close of the 18th century, with (Hoog)Duytsch establishing itself as the Dutch exonym for German during this same period. In the 19th century Germany saw the rise of the categorisation of dialects, with German dialectologists terming
1470-805: A Joint Declaration on the Protection of the Wadden Sea was agreed upon to co-ordinate activities and measures for the protection of the Wadden Sea. In 1997, a Trilateral Wadden Sea Plan was adopted. In 1986, the Wadden Sea Area was declared a biosphere reserve by UNESCO . In June 2009, the Wadden Sea (comprising the Dutch Wadden Sea Conservation Area and the German Wadden Sea National Parks of Lower Saxony and Schleswig-Holstein)
1715-524: A comparison between the West Germanic languages, see the sections Phonology, Grammar, and Vocabulary. Dutch dialects are primarily the dialects that are both related with the Dutch language and are spoken in the same language area as the Dutch standard language . Although heavily under the influence of the standard language, some of them remain diverse and are found in the Netherlands and in
1960-487: A considerably more massive and paler bill, which is yellow even in juveniles unlike in bald and white-tailed eagles. Juvenile Steller's sea eagles are a distinctly darker soot colour than juvenile white-tailed eagles with even less whitish showing on the body than the latter species but, on the other hand, the underwing often as white marked as juvenile bald eagles (dissimilarly from juvenile white-tailed eagles), albeit in different pattern. In all three large northern sea eagles,
2205-640: A differentiation with the Central and High Franconian in Germany. The latter would as a consequence evolve (along with Alemannic , Bavarian and Lombardic ) into Old High German. At more or less the same time the Ingvaeonic nasal spirant law, moving over Western Europe from west to east, led to the development of Old English (or Anglo-Saxon), Old Frisian and Old Saxon . Hardly influenced by either development, Old Dutch probably remained relatively close to
2450-465: A dozen gulls are known in the prey spectrum from the smallest to all four largest extant species. In the United Kingdom , northern fulmar ( Fulmarus glacialis ) are noted as a common prey species and as such may contribute to locally high levels of DDT and PCB chemicals in nesting eagles. However, fulmars defend themselves by regurgitating a smelly, tar-like oily substance that can impair
2695-421: A few attacks also start to exhaust the eagle, as one immature gave up after 15–28 attempts at a little grebe ( Tachybaptus ruficollis ). While bald eagles may attack diving ducks in the same way, they appear to do so somewhat less regularly and successfully. White-tailed eagles usually have less success hunting dabbling ducks because their normal predator response behaviour is to take flight. In one instance,

#17327582683802940-586: A fifth of the Indonesian language can be traced to Dutch, including many loan words . Indonesia's Civil Code has not been officially translated, and the original Dutch language version dating from colonial times remains the authoritative version. Up to half a million native speakers reside in the United States, Canada and Australia combined, and historical linguistic minorities on the verge of extinction remain in parts of France and Germany. Dutch
3185-759: A hundred years of systematic persecution by humans (from the early 1800s to around World War II ) followed by inadvertent poisonings and epidemics of nesting failures due to various manmade chemical pesticides and organic compounds , which have threatened eagles since roughly the 1950s and continue to be a potential concern. Due to this, the white-tailed eagle was considered endangered or extinct in several countries. Some populations have since recovered well, due to governmental protections, dedicated conservationists and naturalists protecting habitats and nesting sites, partially regulating poaching and pesticide usage, as well as careful reintroductions into parts of their former range. White-tailed eagles usually live most of
3430-501: A hypothesis by De Grauwe, In northern West Francia (i.e. modern-day Belgium) the term would take on a new meaning during the Early Middle Ages , when, within the context of a highly dichromatic linguistic landscape, it came to be the antonym of *walhisk (Romance-speakers, specifically Old French ). The word, now rendered as dietsc (Southwestern variant) or duutsc (Central and Northern Variant), could refer to
3675-410: A large bird of prey, widely distributed across temperate Eurasia . Like all eagles, it is a member of the family Accipitridae (or accipitrids) which also includes other diurnal raptors such as hawks , kites , and harriers . One of up to eleven members in the genus Haliaeetus , which are commonly called sea eagles, it is also referred to as the white-tailed sea-eagle . Sometimes, it is known as
3920-420: A long time for them to dry. This may also make them vulnerable to losing their catch to other white-tailed eagles since their flight may be impaired until the wings are dried. Therefore, when hunting fish, they will fly to a feeding perch or nest as soon as possible most of the time. Another option when taking particularly large fish is for the eagle to stay in the water and row, swimming using their wings, across
4165-454: A longer and differently marked tail. At all ages, the white-tailed eagle averages a duller, slightly darker and browner colour overall than the Pallas's fish eagle. Pallas's fish eagles are mid-brown on the body in juvenile plumage with no paler feather edging as seen in juveniles and especially subadults of the larger species. Adult Pallas's fish eagles are immediately distinctive rufous hue with
4410-432: A lower yield, fish of up to 30 cm (12 in) are taken secondarily and fish between 30 and 60 cm (0.98 and 1.97 ft) are preferred since they have the highest nutritional benefit. Fish taken can exceed 0.9 to 1 m (3.0 to 3.3 ft) but since they can start to considerably exceed the weight of the eagle itself, they may prove too heavy to carry. One large Atlantic halibut ( Hippoglossus hippoglossus )
4655-648: A lowland species, the species is known to live at elevations of 1,500 to 2,300 m (4,900 to 7,500 ft) so long as there is water access in some parts of Central Asia and Siberia . In coastal areas, the species may range from high sea cliffs down to low-lying islands and archipelagos . Especially in winter, many white-tailed eagles often frequent low coastal spots, estuaries and coastal marshes . Several studies have supported that coastal areas are preferred when available during winter. In many areas, white-tailed eagles can seem to switch freely between usually cliff habitat and wooded spots for nesting sites and
4900-512: A majority staying near the Baltic coast. However, some eagles that hatched from nests in Germany have been found as far south as in Italy, 1,030 km (640 mi) away to the southeast, or to Gironde , France , 1,520 km (940 mi) to the southwest. In several parts of Russia, quite unlike many European populations, the white-tailed eagle seems to be largely migratory. In the far east,
5145-620: A mallard was caught while flying in mid-air, but usually the much larger eagle is unable to capture ducks in flight. While somewhat less swift in flight, healthy geese can usually outpace a heavier eagle as well and one bean goose ( Anser fabalis ) was even recorded to have defended itself successfully against an eagle's attack even though this goose was injured. White-tailed eagles often hunt dabbling ducks and geese most successfully when they are moulted into their eclipse plumage which renders them temporarily flightless. Swans during winter may find themselves forced to land due to their bulk on
SECTION 20
#17327582683805390-527: A minority language in Germany and northern France's French Flanders . Though Belgium as a whole is multilingual, three of the four language areas into which the country is divided ( Flanders , francophone Wallonia , and the German-speaking Community ) are largely monolingual, with Brussels being bilingual. The Netherlands and Belgium produce the vast majority of music , films , books and other media written or spoken in Dutch. Dutch

Brabantian expands into small parts in the west of Limburg while its strong influence on the East Flemish of East Flanders and eastern Zeelandic Flanders weakens towards the west. In a small area in the northwest of North Brabant ( Willemstad ), Hollandic is spoken. Conventionally, the Kleverlandish dialects are distinguished from Brabantian, but there are no objective criteria apart from geography to do so. Over 5 million people live in an area with some form of Brabantian being
5880-575: A more restricted but more sharply demarked paler buffy head. Bald eagle juveniles may be found together with white-tailed eagles in the Aleutian islands (where the white-tailed eagle formerly bred until about 30 years ago) and when vagrants of white-tails occur in Alaska. Juveniles of bald and white-tailed eagles often strongly resemble each other but the bald eagles have a shorter neck, a relatively longer and squarer tail, and somewhat less broad wings. In
6125-635: A much stronger preference for fish in Greenland by 1983, as fish comprised an extreme 91.8% of 660 items. However, this kind of direct continuous observation of food deliveries to nests is not always possible. Furthermore, despite similar bias for prey that is large and leaves conspicuous remains (including any larger fish, bird or mammal), in the bald eagle it was found that fish were usually detectable and dominant in remains and pellets. Most modern biologists may need to leave some fish unidentified but will account for different methodologies of prey study to get
6370-438: A nest is approached (usually recorded while directed towards humans). The young let out a monotonous veee-veee when hungry (or "bored") which intensifies if the eaglets are not fed or brooded immediately. Given reasonable view, adult white-tailed eagles are difficult to mistake for any other bird. There are no other eagles with fully white tails in their range except for in the easternmost limits of their range, their cousins
6615-441: A nest with some security. Although a relatively gregarious raptor, especially among wintering birds and juveniles and immature birds, they are territorial and intrusion by a male in adult plumage often provokes vigorous fighting, in which either combatant can even die. In some cases, these vicious fights can cause damage to the nest as the two fighting eagles plummet down trying to slash at each other. The white-tailed eagle's diet
6860-420: A number of closely related, mutually intelligible dialects spoken in the former Old Dutch area. Where Old Dutch fragments are very hard to read for untrained Modern Dutch speakers, the various literary works of Middle Dutch are somewhat more accessible. The most notable difference between Old and Middle Dutch is in a feature of speech known as vowel reduction , whereby vowels in unstressed syllables are leveled to
7105-495: A perfect West Germanic dialect continuum remained present; the division reflects the contingent future contribution dialect groups would have to the later languages. The early form of Dutch was a set of Franconian dialects spoken by the Salian Franks in the 5th century. These happened to develop through Middle Dutch to Modern Dutch over the course of fifteen centuries. During that period, they forced Old Frisian back from
7350-579: A political border, because the traditional dialects are strongly influenced by the national standard varieties. While a somewhat heterogeneous group of Low Franconian dialects, Limburgish has received official status as a regional language in the Netherlands and Germany, but not in Belgium. Due to this official recognition, it receives protection by chapter 2 of the European Charter for Regional or Minority Languages . Afrikaans , although to

Young white-tailed eagles are also potentially confusable with any Aquila , but should be obvious even as a silhouette in its huge wings, relatively truncated and slightly wedge-shaped tail and obvious projection of the neck and head. All Aquila lack pale the axillary band often visible on juvenile and subadult white-tailed eagles. Some greater spotted eagles ( Clanga clanga ) can suggest

7840-516: A result, about 90% of all the species that historically inhabited that part of the Wadden Sea are at risk. The Wadden Sea is an important habitat for both harbour and grey seals . Harbour porpoises and white-beaked dolphins are the sea's only resident cetaceans . They were once extinct in the southern part of the sea but have also re-colonized that area again. Many other cetaceans only visit seasonally, or occasionally. In early history, North Atlantic right whales and gray whales (now extinct in
8085-509: A result, when West Flemings try to talk Standard Dutch, they are often unable to pronounce the g-sound, and pronounce it similar to the h-sound. This leaves, for example, no difference between " held " (hero) and " geld " (money). Or in some cases, they are aware of the problem, and hyper-correct the "h" into a voiced velar fricative or g-sound, again leaving no difference. The West Flemish variety historically spoken in adjacent parts in France
8330-665: A revolution is when the Dutch standard language emerged and quickly established itself. The development of the Dutch language is illustrated by the following sentence in Old, Middle and Modern Dutch: Among the Indo-European languages , Dutch is grouped within the Germanic languages , meaning it shares a common ancestor with languages such as English, German, and the Scandinavian languages . All Germanic languages are subject to
8575-431: A richer, more deeply dark brown (or somewhat rufescent ) than average with perhaps a mild increase in average darkness of hue to the east of the species' range. When many of the feathers are freshly moulted, they can take on a slight purplish gloss. The brownish hue of the adult overall makes the somewhat wedge-shaped white tail stand out in contrast. All the bare parts of the adult's body are yellow in colour, including
8820-436: A second language and is the third most spoken Germanic language. In Europe, Dutch is the native language of most of the population of the Netherlands and Flanders (which includes 60% of the population of Belgium ). Dutch was one of the official languages of South Africa until 1925, when it was replaced by Afrikaans , a separate but partially mutually intelligible daughter language of Dutch. Afrikaans, depending on
9065-523: A sheet of ice over water if they can find no open water, which can make their feet stuck to the ice. White-tailed eagles have been recorded utilizing this disability to attack and kill swans. They've also been seen to attack numerous waterfowl when the birds are injured by buckshot from duck hunters. Due to their status as enemy of other large birds, they are frequently mobbed by them and white-tailed eagles have been recorded utilizing violent mobbings to suddenly turn over in flight and predaceously grab one of
9310-522: A significant degree mutually intelligible with Dutch, is usually not considered a dialect but instead a separate standardised language . It is spoken in South Africa and Namibia. As a daughter language of 17th-century Dutch dialects, Afrikaans evolved in parallel with modern Dutch, but was influenced by various other languages in South Africa. West Frisian ( Westerlauwers Fries ), along with Saterland Frisian and North Frisian , evolved from
9555-416: A single meal upon capturing a large fish. The crop can bulge to the size of a small grapefruit after they've consumed a large meal. Many studies have reflected that the primary foods of white-tailed eagles are fish and water birds. These are the primary food as well for other sea eagle species. However, unlike most Haliaeetus , including the bald eagle and Steller's sea eagle, the water birds tend to take
9800-585: A small and increasing breeding population of white-tailed eagles . However, the biodiversity of Wadden Sea is smaller today than it once was; for birds, greater flamingos and Dalmatian pelicans used to be common as well, at least during the Holocene climatic optimum when the climate was warmer. Due to human activity and a changing environment, species have gone extinct, while others are expected to migrate in. Larger fish including rays , Atlantic salmon and brown trout are still present in several sections of
10045-479: A somewhat different development since the late Middle Ages. Two dialect groups have been given the official status of regional language (or streektaal ) in the Netherlands. Like several other dialect groups, both are part of a dialect continuum that continues across the national border. The Dutch Low Saxon dialect area comprises the provinces of Groningen , Drenthe and Overijssel , as well as parts of

10290-424: A source language, mainly for law and history students. In Indonesia this involves about 35,000 students. Unlike other European nations, the Dutch chose not to follow a policy of language expansion amongst the indigenous peoples of their colonies. In the last quarter of the 19th century, however, a local elite gained proficiency in Dutch so as to meet the needs of expanding bureaucracy and business. Nevertheless,
10535-436: A specimen from Greenland which measured 2.53 m (8 ft 4 in) while another specimen apparently spanned 2.6 m (8 ft 6 in). The bald eagle broadly overlaps in size with the white-tailed eagle. In direct comparison, the white-tailed eagle averages somewhat larger in body mass than the bald eagle and may be marginally larger in bill and talon size, although these linear aspects can be quite similar between
10780-456: A thousand eiders were taken here). Eiders also appeared to be the main prey species in Iceland. There is evidence that a growing white-tailed eagle population is having a net negative effect on eider numbers in some areas, and locally eiders have altered to partial nocturnal foraging apparently to avoid hunting eagles. In inland regions, an avian prey species preferred by white-tailed eagles
11025-552: A unique prestige dialect and has a large dialectal continuum consisting of 28 main dialects, which can themselves be further divided into at least 600 distinguishable varieties. In the Netherlands, the Hollandic dialect dominates in national broadcast media while in Flanders Brabantian dialect dominates in that capacity, making them in turn unofficial prestige dialects in their respective countries. Outside

In addition to trees, they may also use crags , hillocks or high grassy tussocks as hunting perches so long as the perch provides a good overall view of the environment. Fish tend to be grabbed in a shallow dive after a short distance flight from a perch, usually with the eagles only getting their feet wet. Occasionally, though, white-tailed eagles have been recorded plunging right into water, usually while hunting on
11515-558: 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 ( Haliaeetus pelagicus ), adults have yellow feet, beaks and eyes. Another species, likely intermediate between the white-tailed, bald and Steller's sea eagles and the Ichthyophaga type fish eagles,

Sometimes Vlaams (" Flemish ") is used as well to describe Standard Dutch in Flanders , whereas Hollands (" Hollandic ") is occasionally used as a colloquial term for the standard language in the central and northwestern parts of the Netherlands. English uses the adjective Dutch as a noun for

In addition, many Indonesian words are calques of Dutch; for example, rumah sakit "hospital" is calqued on the Dutch ziekenhuis (literally "sickhouse"), kebun binatang "zoo" on dierentuin (literally "animal garden"), undang-undang dasar "constitution" from grondwet (literally "ground law"). These account for some of

Juvenile tail lengths can reach roughly 380 mm (15 in) in both sexes, however. The tarsus is 90 to 101 mm (3.5 to 4.0 in), averaging 95.5 mm (3.76 in). In terms of their killing apparatuses, their hallux claw ,

Indeed, in stark contrast to its written uniformity, Dutch lacks
12985-735: Is a reference to the Low Countries' downriver location at the Rhine–Meuse–Scheldt delta near the North Sea . From 1551, the designation Nederlands received strong competition from the name Nederduytsch (literally "Low Dutch", Dutch being used in its archaic sense covering all continental West Germanic languages). It is a calque of the aforementioned Roman province Germania Inferior and an attempt by early Dutch grammarians to give their language more prestige by linking it to Roman times. Likewise, Hoogduits ("High German") and Overlands ("Upper-landish") came into use as
13230-458: Is a relatively weak and ponderous flier and so too may be often victimized by the eagles. Otherwise the pale plumage of adult male common eiders while they're diving is reported to make them more vulnerable to eagle attacks. Eiders were the leading prey species in Norway making 18.8% of 1612 prey items, as well as in Åland , Finland where the eider comprised 18.63% of 5161 prey items (thus nearly

At an academic level, Dutch is taught in about 175 universities in 40 countries. About 15,000 students worldwide study Dutch at university. In Europe, Dutch is the majority language in the Netherlands (96%) and Belgium (59%) as well as

Nonetheless, they have been recorded eating a few eggs, which they may carry in their beaks rather in their feet, of some seabirds such as kittiwakes , eiders , cormorants and gulls. The most widely recorded avian prey species and, second most widely recorded prey species behind the pike, is the 1.14 kg (2.5 lb) mallard, due to its circumpolar range and commonality in many wetlands areas. However, as aforementioned, healthy mallards are difficult for white-tailed eagles due to their tendency to fly at first sign of danger. However, exploiting

Some semi-captive juveniles on the isle of Rùm , Scotland could eat up to 1.4 kg (3.1 lb) in one sitting. However, in Norway, it was estimated that a family of wild white-tailed eagles including each adult and three fledglings were consuming on average up to 625 g (1.378 lb) per bird each day. Furthermore, one male consumed an estimated 2 kg (4.4 lb) in

White-tailed eagles of all ages typically perch in quite upright positions on exposed branch, rock or other vantage point, but tend to sit more horizontally on the ground or other level surfaces. They have an ample bill with a relatively high culmen, helping to impart a rather narrow and high crowned facial look, especially compared to Aquila eagles . The neck is at times unusually long-looking, more so than in

Furthermore, appropriate habitat is needed in which to execute this hunting and also, of course, to build

Old Dutch is regarded as the primary stage in the development of a separate Dutch language. It was spoken by the descendants of the Salian Franks who occupied what is now the southern Netherlands , northern Belgium , part of northern France, and parts of the Lower Rhine regions of Germany. The High German consonant shift, moving over Western Europe from south to west, caused

Dutch, like English, has not undergone the High German consonant shift , does not use Germanic umlaut as a grammatical marker, has largely abandoned the use of the subjunctive , and has levelled much of its morphology , including most of its case system . Features shared with German, however, include

Pairs regularly roost together, often near to their nest, either on a crag or tree or crevices, overhung ledges or small isolated trees on a crag. The white-tailed eagle may be considered a rather inconsistent and partial migrant. The species seldom migrates in
16170-569: Is so distinct that it might be considered as a separate language variant, although the strong significance of language in Belgian politics would prevent the government from classifying them as such. An oddity of the dialect is that, the voiced velar fricative (written as "g" in Dutch) shifts to a voiced glottal fricative (written as "h" in Dutch), while the letter "h" becomes mute (like in French).

Each year, some 1,500 to 2,000 students take Dutch courses there. In total, several thousand Indonesians study Dutch as a foreign language. Owing to centuries of Dutch rule in Indonesia, many old documents are written in Dutch. Many universities therefore include Dutch as

Due to the similar dietary and nesting habits of sea eagles, they are mostly allopatric in distribution as competition can be considerable between these eagles. Currently, eagles occur in the Hawaiian Islands only as vagrants, but Quaternary bones of Haliaeetus have been found on three of

This bream was reported in 10 of 18 dietary studies and was the main prey in the Polesie State Radioecological Reserve , Belarus, in the Ural mountains region of Russia, and in the Kostomuksha Nature Reserve , Russia. Breams taken by reeding eagles at Augustów Forest , Poland ranged from 0.2 to 2 kg (0.44 to 4.41 lb) in weight. Many varieties of fish are taken opportunistically and randomly, as opposed to pike and bream, which can locally appear to be selected out of proportion to their regional population. Particularly diverse in

The coot is the second most widely represented bird prey species (and fourth species of any class known overall) in 18 dietary studies. Coots bunch together in marshy spots when approached by a flying eagle and as many as five eagles at once have been recorded attacking large flocks on the water. Coots' behaviour often endangers them to large raptors: they seldom dive, are weaker and slower fliers than most water birds and are collectively often less wary and more approachable than most waterfowl are. Coot were strongly
17885-404: Is the case with the ( standardised ) West Frisian language . It is spoken alongside Dutch in the province of Friesland . Dutch dialects and regional languages are not spoken as often as they used to be, especially in the Netherlands. Recent research by Geert Driessen shows that the use of dialects and regional languages among both Dutch adults and youth is in heavy decline. In 1995, 27 percent of
18130-452: Is the following year in March or April, with two more subsequent moults usually beginning around this time for the next couple of years. Like other large raptors, feathers are moulted at slow intervals so as not to inhibit food capture. Only relatively small proportions of the flight feathers are moulted each year. Moulting occurs more or less continuously, although it may pause in winter if food
18375-530: Is the sole official language, and over 60 percent of the population speaks it as a mother tongue . Dutch is the obligatory medium of instruction in schools in Suriname, even for non-native speakers. A further twenty-four percent of the population speaks Dutch as a second language . Suriname gained its independence from the Netherlands in 1975 and has been an associate member of the Dutch Language Union since 2004. The lingua franca of Suriname, however,
18620-461: Is typically large as in all Haliaeetus , ranging from 45 to 65 mm (1.8 to 2.6 in), with an average of 56.1 mm (2.21 in). The average culmen length of the bald eagle is 54.3 mm (2.14 in), thus averaging slightly smaller. However, the average culmen length in the large bald eagles of Alaska is considerably larger than other bald eagles as well as most white-tailed eagles at up to 75 mm (3.0 in) and can even rival
18865-435: Is usually more evident in flying than perched birds, with sometimes a slightly bulging section of feathers manifesting on the wing secondaries . The species tends to fly with shallow wing beats; at times the wing beats can be fairly fast for a bird of this size, but interspersed at times with gliding. At a great distance, this flight style may be suggestive of a large brown heron . The wings are held flat or slightly upraised at
19110-404: Is varied, opportunistic and seasonal. Prey specimens can often include fish, birds and, mostly in a secondary capacity, mammals. White-tailed eagles are powerful predators and capable of attacking large prey of considerable sizes but, like most predators, prefer prey that is vulnerable and easy for them to capture. Especially during the winter (and opportunistically in all seasons), many birds of
19355-480: The Description de l'Égypte . The name Haliaeetus is Neo-Latin for "sea-eagle", from Ancient Greek hali- , "sea-" and aetos , "eagle". The specific albicilla , "white-tailed", is from Neo-Latin albi- , "white" and cilla , "tail". The Anglo-Saxon name erne means "soarer", and it is cognate to Swedish örn and Finnish aarni . It has many Gaelic names, including iolar sùil na grèine or 'eagle of
19600-531: The 2006 New Zealand census , 26,982 people, or 0.70 percent of the total population, reported to speak Dutch to sufficient fluency that they could hold an everyday conversation. In contrast to the colonies in the East Indies , from the second half of the 19th century onwards, the Netherlands envisaged the expansion of Dutch in its colonies in the West Indies . Until 1863, when slavery was abolished in

The bird returned to
20090-525: The Brahminy kite ( Haliastur indus ) (historically sometimes referred to as the "red-backed sea eagle") and the palm-nut vulture ( Gypohierax angolensis ) (which was once widely referred to as the "vulturine fish eagle"). The relation of these species to the sea eagles is partially borne out by their genetic sequencing. Other groups, beyond milvine kites and Old World vulture, of modern accipitrids that are seemingly in some way related, albeit distantly, to
20335-455: The Brussels and Flemish regions of Belgium . The areas in which they are spoken often correspond with former medieval counties and duchies. The Netherlands (but not Belgium) distinguishes between a dialect and a streektaal (" regional language "). Those words are actually more political than linguistic because a regional language unites a large group of very different varieties. Such is
20580-481: The Dutch Language Union . The Dutch Caribbean municipalities ( St. Eustatius , Saba and Bonaire ) have Dutch as one of the official languages. In Asia, Dutch was used in the Dutch East Indies (now mostly Indonesia ) by a limited educated elite of around 2% of the total population, including over 1 million indigenous Indonesians, until it was banned in 1957, but the ban was lifted afterwards. About
20825-614: The Frisian islands and the mainland coastal marshes , is also called the Wadden Coast. In Germany the area is referred to as North Sea Coast ( Nordseeküste ). The embanked polderlands and saltmarshes in the Wadden Sea area – including the Elbe Marshes – are referred to in Germany as North Sea coastal marshes ( Nordseemarschen ). More recent are terms such as Waddenland, Wadden Sea area and Wadden Sea Region. The latter term
21070-593: The Griffon vulture ( Gys fulvus ), as the colouring of the two species is vaguely similar and they can overlap somewhat in size although the vulture can average rather heavier and longer winged. However even at long range, the relatively tiny head, distinctly curved trailing wing-edges and more raised wings make the vulture distinctive from the white-tailed eagle. Juveniles may be harder to distinguish, mainly from other sea eagles in few areas of overlap. In northern Mongolia (perhaps spilling over into southern Siberia ),
21315-601: The Grimm's law and Verner's law sound shifts, which originated in the Proto-Germanic language and define the basic features differentiating them from other Indo-European languages. This is assumed to have taken place in approximately the mid-first millennium BCE in the pre-Roman Northern European Iron Age . The Germanic languages are traditionally divided into three groups: East (now extinct), West , and North Germanic. They remained mutually intelligible throughout
21560-512: The Levant countries, Azerbaijan and Iran down to even the Persian Gulf , albeit seldom is the species to be found commonly or reliably anywhere in these regions. Further east, rare wintering areas are known in a few small, scarce pockets of Turkmenistan, Afghanistan , Uzbekistan , Tajikistan and Pakistan . It is a rare winter visitor to India , namely the extreme northwest and along
21805-591: The Low Franconian languages, paired with its sister language Limburgish or East Low Franconian. Its closest relative is the mutually intelligible daughter language Afrikaans. Other West Germanic languages related to Dutch are German , English and the un-standardised languages Low German and Yiddish . Dutch stands out in combining some Ingvaeonic characteristics (occurring consistently in English and Frisian and reduced in intensity from west to east over
22050-702: The Middle East , the white-tailed eagle may still be found breeding only along the southern coast of the Caspian Sea in northern Iran and southwestern Turkmenistan . Discontinuously, they are found as residents in Kazakhstan where they live in a long strip of the southern part of the country starting at the Aral Sea and the northwestern portion (but not, as far as is known, breeding in the Kazakh part of
22295-603: The Migration Period . Dutch is part of the West Germanic group, which also includes English, Scots , Frisian , Low German (Old Saxon) and High German . It is characterised by a number of phonological and morphological innovations not found in North or East Germanic. The West Germanic varieties of the time are generally split into three dialect groups: Ingvaeonic (North Sea Germanic), Istvaeonic (Weser–Rhine Germanic) and Irminonic (Elbe Germanic). It appears that
22540-536: The Netherlands in 2006 and in 2020 the number of breeding pairs had increased to 20. It might have bred in the Faroe Islands up until the 17th century, but evidence is lacking; there are only about a dozen records of vagrant white-tailed eagles from the archipelago since 1800. In Anatolia , it only remains as a breeder in sparse and small pockets of Turkey and Georgia , taken as a region there are likely to be fewer than 30 breeding pairs in this region. In
22785-531: The Randstad , which are Hollandic dialects, do not diverge from standard Dutch very much, but there is a clear difference between the city dialects of Rotterdam , The Hague , Amsterdam and Utrecht . In some rural Hollandic areas more authentic Hollandic dialects are still being used, especially north of Amsterdam. Another group of dialects based on Hollandic is that spoken in the cities and larger towns of Friesland , where it partially displaced West Frisian in
23030-482: The Saint Marcellus' floods of 1219 and 1362, Burchardi flood of 1634 and Christmas Flood of 1717 . Some of these also significantly changed the coastline. Numerous dikes and several causeways have been built, and as a result recent floods have resulted in few or no fatalities (even if some dikes rarely and locally have been overrun in recent history). This makes it among the most human-altered habitats on
23275-543: The Southern Netherlands (now Belgium and Luxembourg), developments were different. Under subsequent Spanish , Austrian and French rule , the standardisation of Dutch language came to a standstill. The state, law, and increasingly education used French, yet more than half the Belgian population were speaking a variety of Dutch. In the course of the 19th century, the Flemish Movement stood up for

Thus, the mean prey size falls just slightly short of the mean prey mass of the golden eagle, which globally averages about 1.35 to 1.63 kg (3.0 to 3.6 lb). Overall, nearly 70 species of fish are known to be taken from throughout
23765-606: The alluvial wetlands of Croatia, 95% of nests were found within 4 km (2.5 mi) of deep freshwater. In some areas, white-tailed eagles readily visit commercial fish farms , carp ponds and similar areas with easily accessible food but they will usually avoid areas where human disturbances (especially noisy varieties such as construction , water sporting and heavy boating activities and hunting ) commonly occur. However, forestry activity and resulting lessened numbers of tall mature trees and large tree stands in Estonia
24010-429: The common lumpsucker ( Cyclopterus lumpus ), which averages up to 1.43 kg (3.2 lb) but is usually smaller, made up 24% of fish taken and the 2.13 kg (4.7 lb) Atlantic wolffish ( Anarhichas lupus ) made up 17% of fish taken. However, fish were secondary to birds overall in Norway. Per two studies from Sweden, fish were usually the main food unlike in Norway and Finland, and could comprise 51–60% of
24255-471: The continental West Germanic plane) with dominant Istvaeonic characteristics, some of which are also incorporated in German. Unlike German, Dutch (apart from Limburgish) has not been influenced at all by the south to north movement of the High German consonant shift and had some changes of its own. The cumulation of these changes resulted over time in separate, but related standard languages with various degrees of similarities and differences between them. For
24500-434: The differences in vocabulary between Indonesian and Malay. Some regional languages in Indonesia have some Dutch loanwords as well; for example, Sundanese word Katel or "frying pan" origin in Dutch is " ketel ". The Javanese word for "bike/ bicycle " " pit " can be traced back to its origin in Dutch " fiets ". The Malacca state of Malaysia was also colonized by the Dutch in its longest period that Malacca
24745-423: The ern or erne (depending on spelling by sources), gray sea eagle and Eurasian sea eagle . While found across a wide range, today breeding from as far west as Greenland and Iceland across to as far east as Hokkaido , Japan , they are often scarce and spottily distributed as a nesting species, mainly due to human activities. These have included habitat alterations and destruction of wetlands , about
24990-410: The waterfowl favoured in the avian diet tend to be highly wary and will more often than not escape. The white-tailed eagles must then attack birds at times of vulnerability or injury, or will often utilize the prey's escape tactics against them. Diving ducks and other diving water birds will be taken preferentially where they are available. In hunting diving birds, they utilize a technique of forcing
25235-523: The white-bellied sea eagle juvenile, likely a closely related species) more typical of juveniles in other species and it also dwells more so in dense, coastal forests where it feeds mostly on birds and mammals rather than fish and water birds . Outside of the genus Haliaeetus , among other extant forms, they appear to be most closely related to milvine kites and Old World vultures , based on modern forms from these subfamilies that broadly share morphological and life history traits with sea eagles:
25480-656: The 1.23 kg (2.7 lb) red-breasted goose ( Branta ruficollis ) to the non-native 3.69 kg (8.1 lb) Canada goose ( Branta canadensis ). Goslings and juveniles are usually targeted, but adult geese are also taken, especially while incubating or weakened by various reasons. Another large water bird taken as adults are 4.98 kg (11.0 lb) common loons ( Gavia immer ). Large waders are taken when possible, including grey herons and great bitterns ( Botaurus stellaris ), both weighing between 1 and 2 kg ( 2 + 1 ⁄ 4 and 4 + 1 ⁄ 2 lb). Larger 2.93 kg (6.5 lb) black and
25725-518: The 14th to 15th century onward, its urban centers ( Deventer , Zwolle , Kampen , Zutphen and Doesburg ) have been increasingly influenced by the western written Dutch and became a linguistically mixed area. From the 17th century onward, it was gradually integrated into the Dutch language area. Dutch Low Saxon used to be at one end of the Low German dialect continuum . However, the national border has given way to dialect boundaries coinciding with

Hollandic together with inter alia Kleverlandish and North Brabantian , but without Stadsfries, are the Central Dutch dialects . Brabantian is named after the historical Duchy of Brabant , which corresponded mainly to the provinces of North Brabant and southern Gelderland , the Belgian provinces of Antwerp and Flemish Brabant , as well as Brussels (where its native speakers have become
26215-445: The 1979 study, 68% of the diet would have been represented by birds and only 20% by fish but comprehensive observation shifted it to show fish were the primary food at 58% and birds were secondary at 30%. This study claimed this is often because the bones of fish are dissolved by the large digestive tract of the eagles upon consumption and may thus leave almost nothing in remains and to some extent in pellets. Subsequent studies here showed
26460-520: The 19th century. Mudflat hiking , i.e., walking on the sandy flats at low tide, has become popular in the Wadden Sea. It is also a popular region for pleasure boating. The German part of the Wadden Sea was the setting for the 1903 Erskine Childers novel The Riddle of the Sands and Else Ury 's 1915 novel Nesthäkchen in the Children's Sanitorium . The area bordering the Wadden Sea, including
26705-692: The 3.44 kg (7.6 lb) white stork ( Ciconia ciconia ) of all ages can be preyed upon. Black and white storks are the primary prey species in the Polesie State Radioecological Reserve, Belarus, where they comprised 12.6% (second most regular prey species) and 6.3% (fourth most regular) of the diet, respectively. Large numbers of black storks were also taken in Augustów Primeval Forest where remains of nearly 50 individuals were found around eagle nests. White-tailed eagles even attack and prey on both
26950-544: The Black Sea which have been recorded 330 km (210 mi) north of their natal site and 510 km (320 mi) northeast of their natal site. Territory size in white-tailed eagles may vary from 52 to 415 km (20 to 160 sq mi), usually less than 130 km (50 sq mi), per one estimate. However, home ranges in northeastern Germany were much smaller than this, at 2.25 to 19.16 km (0.87 to 7.40 sq mi). While territorial behaviour
27195-539: The Caspian Sea coast). The only country in which the white-tailed eagle is found over a continuous and extremely large area is Russia . The species is found broadly everywhere in Russia from European Russia in the west to the Bering Sea in the east, only being fully absent as a nester as far as is known from the high Arctic regions and a section bordering westernmost Kazakhstan, although it breeds to south of this in
27440-417: The Dutch adult population spoke a dialect or regional language on a regular basis, but in 2011, that was no more than 11 percent. In 1995, 12 percent of children of primary school age spoke a dialect or regional language, but in 2011, that had declined to four percent. Of the officially recognised regional languages Limburgish is spoken the most (in 2011 among adults 54%, among children 31%) and Dutch Low Saxon
27685-490: The Dutch government remained reluctant to teach Dutch on a large scale for fear of destabilising the colony. Dutch, the language of power, was supposed to remain in the hands of the leading elite. After independence, Dutch was dropped as an official language and replaced by Indonesian , but this does not mean that Dutch has completely disappeared in Indonesia: Indonesian Dutch , a regional variety of
27930-548: The Dutch language itself, as well as a broader Germanic category depending on context. During the High Middle Ages " Dietsc / Duutsc " was increasingly used as an umbrella term for the specific Germanic dialects spoken in the Low Countries , its meaning being largely implicitly provided by the regional orientation of medieval Dutch society: apart from the higher echelons of the clergy and nobility, mobility
28175-415: The Dutch standard language is largely absent, and speakers of these Dutch dialects will use German or French in everyday speech. Dutch is not afforded legal status in France or Germany, either by the central or regional public authorities, and knowledge of the language is declining among younger generations. As a foreign language , Dutch is mainly taught in primary and secondary schools in areas adjacent to

Approximate distribution of native Dutch speakers worldwide: Dutch is an official language of the Netherlands proper (not enshrined in the constitution but in administrative law ), Belgium, Suriname, the Dutch Caribbean municipalities (St. Eustatius, Saba and Bonaire), Aruba , Curaçao and Sint Maarten . Dutch
28665-408: The Dutch, was still spoken by about 500,000 half-blood in Indonesia in 1985. Yet the Indonesian language inherited many words from Dutch: words for everyday life as well as scientific and technological terms. One scholar argues that 20% of Indonesian words can be traced back to Dutch words, many of which are transliterated to reflect phonetic pronunciation e.g. kantoor "office" in Indonesian
28910-756: The Frankish tribes fit primarily into the Istvaeonic dialect group with certain Ingvaeonic influences towards the northwest, which are still seen in modern Dutch. The Frankish language itself is not directly attested, the only possible exception being the Bergakker inscription , found near the Dutch city of Tiel , which may represent a primary record of 5th-century Frankish. Although some place names recorded in Roman texts such as vadam (modern Dutch: wad , English: "mudflat"), could arguably be considered as
29155-407: The German dialects spoken in the mountainous south of Germany as Hochdeutsch ("High German"). Subsequently, German dialects spoken in the north were designated as Niederdeutsch ("Low German"). The names for these dialects were calqued by Dutch linguists as Nederduits and Hoogduits . As a result, Nederduits no longer serves as a synonym for the Dutch language. In the 19th century,
29400-531: 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 is one of
29645-462: The Low Countries. In fact, Old Frankish could be reconstructed from Old Dutch and Frankish loanwords in Old French. The term Old Dutch or Old Low Franconian refers to the set of Franconian dialects (i.e. West Germanic varieties that are assumed to have evolved from Frankish ) spoken in the Low Countries during the Early Middle Ages , from around the 5th to the 12th century. Old Dutch
29890-576: The Netherlands and Flanders . In French-speaking Belgium , over 300,000 pupils are enrolled in Dutch courses, followed by over 23,000 in the German states of Lower Saxony and North Rhine-Westphalia , and about 7,000 in the French region of Nord-Pas-de-Calais (of which 4,550 are in primary school). At an academic level, the largest number of faculties of neerlandistiek can be found in Germany (30 universities), followed by France (20 universities) and
30135-412: The Netherlands and Belgium, the dialect spoken in and around the German town of Kleve ( Kleverlandish ) is historically and genetically a Low Franconian variety. In North-Western France, the area around Calais was historically Dutch-speaking (West Flemish), of which an estimated 20,000 are daily speakers. The cities of Dunkirk , Gravelines and Bourbourg only became predominantly French-speaking by
30380-539: The Netherlands, although there are recognisable differences in pronunciation, comparable to the pronunciation differences between standard British and standard American English. In 1980 the Netherlands and Belgium concluded the Language Union Treaty . This treaty lays down the principle that the two countries must gear their language policy to each other, among other things, for a common system of spelling. Dutch belongs to its own West Germanic sub-group,
30625-551: The Netherlands, even with infrequent modern breeding in the northern coastal areas. A wintering population is known in western Germany from North Rhine-Westphalia to Bonn , as well as far northern Germany. In Denmark, they both breed and winter throughout much of the country, but in particular the Wadden Sea region attracts many white-tailed eagles, mostly immatures, from elsewhere in Denmark and neighbouring countries during
30870-665: The North Atlantic) were present in the region, perhaps using the shallow, calm waters for feeding and breeding. It has been theorized that they were hunted to extinction in this region by shore-based whalers in medieval times. They are generally considered long-extinct in the region, but in the Netherlands, a possible right whale was observed close to beaches on Texel in the West Frisian Islands and off Steenbanken, Schouwen-Duiveland in July 2005. Recent increases in
31115-910: The Russian Far East are known to occasionally disperse across the Bering Sea to North America in several parts of the Aleutian Islands , the Pribilof Islands and some of mainland coastal Alaska down to Kodiak Island . Some white-tailed eagles even bred in Alaska on Attu Island in the late 1970s to the early 1980s (until 1984 when the last attempts were recorded) but it was not clear whether young were ever successfully fledged. White-tailed eagles may be found in varied habitat but usually are closely associated with water and generally occurs in lowland areas. Although mainly

Their northern limits occur in Russia to the Ob river to 70 degrees north at the mouth of the Yenisei River and on the Gyda and Yamal Peninsulas , to the Kolyma , Indigirka and Lena rivers to above 72 degrees north, even to 75 degrees north on the Taymyr Peninsula . They are said to be common around the White Sea , reportedly even the most abundant bird of prey locally and found both on coasts and inland lakes, although breeding rates are low due to

Wintering congregations at the Baltic coast and on the River Elbe from 37 winters show that arrivals begin in November, with numbers peaking in January and then declining during March and early April. Although juveniles usually return to their natal area some apparently overshoot these areas, such as those returning to Romania or on
31850-517: The Steller's sea eagle may rival it in that respect. In one sample from Norway , five male white-tailed eagles were found to average 2.26 m (7 ft 5 in) and eight females were found to average 2.37 m (7 ft 9 in). In another sample of wild birds of unspecified origin, five males were found to average 2.1 m (6 ft 11 in) and seven females averaged 2.3 m (7 ft 7 in). Record wingspans have included
32095-607: The United Kingdom (5 universities). Despite the Dutch presence in Indonesia for almost 350 years, as the Asian bulk of the Dutch East Indies , the Dutch language has no official status there and the small minority that can speak the language fluently are either educated members of the oldest generation, or employed in the legal profession such as historians, diplomats, lawyers, jurists and linguists/polyglots, as certain law codes are still only available in Dutch.

European oyster once formed large beds in the region and was still present until a few decades ago, when extirpated due to a combination of disease and the continued spread of the invasive Pacific oyster , which now forms large beds in the Wadden Sea. Especially the southwestern part of the Wadden Sea has been greatly reduced. Historically, the Rhine was by far the most important river flowing into this section, but it has been greatly reduced due to dams. As

The world's only remaining natural population of houting survives in the Danish part of the Wadden Sea and it has been used as a basis for reintroductions further south, but considerable taxonomic confusion remains over its status (whether it is the same as the houting that once lived further south in
33075-621: The West Indies, slaves were forbidden to speak Dutch, with the effect that local creoles such as Papiamento and Sranan Tongo which were based not on Dutch but rather other European languages, became common in the Dutch West Indies. However, as most of the people in the Colony of Surinam (now Suriname ) worked on Dutch plantations, this reinforced the use of Dutch as a means for direct communication. In Suriname today, Dutch
33320-493: The White Sea were found well over 2,000 km (1,200 mi) away to the west, in countries such as Hungary and Italy. Return spring migration to the White Sea is by February–March. During winter, whether long-distance migrants or short-distance dispersers, white-tailed eagles tend to become gregarious, especially younger immature birds. Many such groups can contain up to 10 and, in areas near large breeding populations such as
33565-542: The adults, although the juveniles typically have a somewhat larger average wing and tail length than the adults. In the white-tailed eagle, body mass can typically range from 4 to 6.9 kg (8.8 to 15.2 lb) in females. The slightly smaller male may typically weigh from 3.1 to 5.4 kg (6.8 to 11.9 lb). Average weights in European white-tailed eagles can range from 4.02 kg (8.9 lb) in five males and 5.11 kg (11.3 lb) in nine females to (from
33810-565: The aforementioned water birds are modest of size and taken largely due to ease (diving water birds, whether healthy or infirm, and usually infirm or moulting dabbling water birds), white-tailed eagles routinely attack larger water birds as well. In many areas, large numbers of greylag geese ( Anser anser ), Europe's largest native wild goose, are taken. For example, they were the main prey, making up 28.2% of 192 prey items, for wintering eagles in Oostvaardersplassen , Netherlands, and
34055-513: The average female white-tailed eagle (the average weight of male Steller's is not known) while the average European golden eagle may weigh about 11–12% less than the average European white-tailed eagle and the bald eagle species as a whole about 10% less than the white-tailed eagle species. The most reliable method to sex birds is by tarsus width and depth and bill depth but these are infrequently measured. In some cases females are as much as 25% heavier and 15% greater in linear dimensions, though
34300-416: The bald eagle and Steller's sea eagle, which in adults are different in all other respects of plumage. Even in poor light, the bald species shows a sharp demarcation from white to dark brown whereas the colour contrast is far subtler in white-tailed eagles between their brown body (of a paler hue than that of a bald eagle) and buff-coloured head. At a great distance, the adult may be potentially confusable with
34545-448: The bald eagle, which can give the upper body a vulturine appearance. The tail is relatively short, and in some adults it can appear disproportionately stubby in relation to the massive body, and slightly wedge-shaped. All ages have a well-feathered tibia but bare tarsi . In flight, the wings are extremely broad and deeply fingered, with the usual tendency for at least six fingers to be visible. Juveniles are longer tailed than adults, which
34790-457: The bill, cere , feet and eyes. Juvenile and immature white-tailed eagles are a much darker brown than the adults and are more unevenly marked, with whitish feather edgings variably showing, mostly manifesting in some small areas of the underside and under-wing, with a narrow white axillary strip usually apparent. The upperside is usually similarly darkish brown but variable based on extent of blackish-brown tip to otherwise buff-brown feathers of
35035-622: The birds mobbing them, including large gulls and even a northern goshawk ( Accipiter gentilis ). As an opportunistic predator, it often takes young birds freely as well as adult and fledged juvenile birds. In general, due to different nesting situations, white-tailed eagles instead of dabbling or diving water birds usually attack the more conspicuous or open nests of gulls, those of several other types of seabird , large corvids or other accipitrids. In Germany and Scotland, up to 86% of gulls taken were nestlings and juveniles. Cases of white-tailed eagles eating eggs, instead of nestlings or older birds,
35280-784: The birds to dive repeatedly to avoid attacks, until the victim is exhausted from the efforts and can then be caught. Usually while hunting like this, the white-tailed eagle tends to circle low to stay close to the intended victim, with birds diving in shallower water being preferred. Ducks with conspicuous plumage, such as male common eiders ( Somateria mollissima ), with their pale plumage, may be easier to see under water and so may be taken somewhat more via this hunting method. Beyond waterfowl, both loons and grebes have been seen to be successfully hunted in this way. Eagles were recorded doing up to 12 attacks on eiders in Russia and were usually successful in procuring prey. Even as many as 65 passes have recorded in less than 45 minutes but more than
35525-421: The border of Nepal to Bhutan and extreme northern Bangladesh . Scattered pockets of wintering birds are known to occur too in central and southern China , into northeastern Myanmar , and more broadly and regularly in much of Northeast China. Good numbers winter too in much of South Korea and Japan down to as far as Honshu . White-tailed eagles dispersing from their breeding grounds or natal sites in
35770-624: The borders of other standard language areas. In most cases, the heavy influence of the standard language has broken the dialect continuum . Examples are the Gronings dialect spoken in Groningen as well as the closely related varieties in adjacent East Frisia (Germany). Kleverlandish is a dialect spoken in southern Gelderland , the northern tip of Limburg , and northeast of North Brabant (Netherlands), but also in adjacent parts of North Rhine-Westphalia (Germany). Limburgish ( Limburgs )
36015-479: The case with the Gronings dialect , which is considered a variety of the Dutch Low Saxon regional language, but it is relatively distinct from other Dutch Low Saxon varieties. Also, some Dutch dialects are more remote from the Dutch standard language than some varieties of a regional language are. Within the Netherlands, a further distinction is made between a regional language and a separate language, which
36260-466: The center of their home range habitat. In some areas, such as Japan, this species may occur in regions with intensive human fishing activity and they may become unusually partially habituated to this human presence. Inland, white-tailed eagles usually require secluded woods, forested areas or groups of trees with tall mature trees and access to freshwater wetlands such as lakes , river systems , marshes or extensive, low-disturbance farmland . In
36505-405: The centuries, having lost land on one side and added it on the other. The Wadden Sea is famous for its rich flora and fauna , especially birds. Hundreds of thousands of waders , ducks , and geese use the area as a migration stopover or wintering site. It is also a rich habitat for gulls and terns , as well as a few species of herons , Eurasian spoonbills and birds-of-prey , including
36750-458: The coast of northwestern continental Europe and the range of low-lying Frisian Islands , forming a shallow body of water with tidal flats and wetlands . It has a high biological diversity and is an important area for both breeding and migrating birds. In 2009, the Dutch and German parts of the Wadden Sea were inscribed on UNESCO 's World Heritage List and the Danish part was added in June 2014. The Wadden Sea stretches from Den Helder , in
36995-402: The coastal dunes. The present islands are a remnant of the former coastal dunes. Towards the North Sea the islands are marked by dunes and wide sandy beaches, and towards the Wadden Sea a low, tidal coast. The impact of waves and currents carrying away sediments is slowly changing both land masses and coastlines. For example, the islands of Vlieland and Ameland have moved eastwards through
37240-534: The colder months, especially in coastal areas such as Norway when preferred fish prey often move to deeper water during winter. Among both fish and bird prey, it is thought that a majority that are caught weigh between 0.5 and 3 kg (1.1 and 6.6 lb). At times it has been said that "most" prey of white-tailed eagles will weigh only 0.5 to 1 kg (1.1 to 2.2 lb). However, the mean prey sizes caught can show greater variability. Three studies showed that mean prey size varied from 578 g (1.274 lb) in
37485-428: The colouring, the bald juvenile is similarly as dark or even darker brown above as white-tailed eagle juveniles but on the underside often has more extensive whitish mottling, especially on the underwing. Steller's sea eagles are usually distinctly larger and longer tailed, with a taller, bulkier look in eagles standing on the ground or perched. Steller's juveniles have a different wing shape (roughly paddle-shaped) and
37730-407: The common people". The term was used as opposed to Latin , the non -native language of writing and the Catholic Church . It was first recorded in 786, when the Bishop of Ostia writes to Pope Adrian I about a synod taking place in Corbridge , England , where the decisions are being written down " tam Latine quam theodisce " meaning "in Latin as well as common vernacular". According to
37975-483: The declaration of independence of Indonesia, Western New Guinea , the "wild east" of the Dutch East Indies , remained a Dutch colony until 1962, known as Netherlands New Guinea . Despite prolonged Dutch presence, the Dutch language is not spoken by many Papuans, the colony having been ceded to Indonesia in 1963. Dutch-speaking immigrant communities can also be found in Australia and New Zealand. The 2011 Australian census showed 37,248 people speaking Dutch at home. At
38220-542: The definition used, may be considered a sister language , spoken, to some degree, by at least 16 million people, mainly in South Africa and Namibia , and evolving from Cape Dutch dialects. In South America, it is the native language of the majority of the population of Suriname , and spoken as a second or third language in the polyglot Caribbean island countries of Aruba , Curaçao and Sint Maarten . All these countries have recognised Dutch as one of their official languages, and are involved in one way or another in
38465-418: The devil? ... I forsake the devil"). If only for its poetic content, the most famous Old Dutch sentence is probably Hebban olla vogala nestas hagunnan, hinase hic enda tu, wat unbidan we nu ("All birds have started making nests, except me and you, what are we waiting for"), is dated to around the year 1100, written by a Flemish monk in a convent in Rochester , England . Since the sentence speaks to
38710-403: The diet. Fish were also somewhat dominant in the foods from two studies in Belarus, making up 48.1–53.7% of the diet. Fish similarly were important to nesting eagles in Hokkaido, Japan where 54% of 533 prey items were fish, led by the 800 g (1.8 lb) Alaska pollock ( Gadus chalcogrammus ) at 18.4%. In different studies of the Danube Delta of Romania, from 44.6% to 79% of the diet
38955-447: The distinction of a subspecies. However, the population appears to be demographically isolated and deserves special protection. At one time an eastern subspecies ( H. a. brooksi ) was proposed as well but there is little evidence supporting this as more than a case of clinal variation in colouring and size (i.e. the eastern average slightly darker and smaller than more westerly ones). As in other sea-eagle species pairs, this one consists of
39200-1081: The dominant food in Wigry National Park, Poland where they made up 44.1% of 299 items, and were also the leading prey in Augustów Primeval Forest (Poland) where they made up 11.59% of the foods. Overall at Wigry and Augustów, birds altogether made up 66.2% and 47.83% of the diets, respectively. In the Danube Delta, Romania, birds climbed in importance of the diet from 21% in 1970 to 50% by 2015, thanks largely to increased numbers of coots. In total, about 38 species of waterfowl are known to be hunted, as well as all available species of loons and grebes, several types of rails , tubenoses as well as herons , storks and other assorted large waders. White-tailed eagles also are known to hunt some 42 species of shorebird , most significantly gulls and alcids . Even shorebirds as small as 21.1 g (0.74 oz) little stint ( Calidris minuta ), 62.6 g (2.21 oz) wood sandpiper ( Tringa glareola ) and 64 g (2.3 oz) common ringed plover ( Charadrius hiaticula ) are known to be preyed upon, albeit quite rarely. More than
39445-424: The end of the 19th century. In the countryside, until World War I , many elementary schools continued to teach in Dutch, and the Catholic Church continued to preach and teach the catechism in Dutch in many parishes. During the second half of the 19th century, Dutch was banned from all levels of education by both Prussia and France and lost most of its functions as a cultural language. In both Germany and France,
39690-403: The female when receiving food from male calls out with tschie-tschie or vueee-vueee . Single or repeated krlee or similar component of calls used in other circumstances, can be variable. Alarm calls tend to be 3–4 short, loud klee or klek notes. Sometimes a different call of alarm or anger, a deep gah-gah-gah or jok-jok-jok , similar to alarm calls of a large gull , is also uttered when
39935-500: The fish prey will float to the surface when infected by fish tapeworm , as is often the case with some fish families such as carp . Fish are also caught after being battered, injured, and killed at power plants, from large-scale fishing nets, or are taken directly from human fishermen. Benthic fish which tend to cling to rocks or sandy soil in shallows may be more vulnerable since they tend to look downward rather than upward and are less competent at escaping predators coming from above
40180-456: The flight of predators and may even kill some intended predators when it is in large quantity, and young juvenile eagles, being less cautious and experienced, are most prone to being severely "oiled". Alcids such as murres tend to become especially important in the diet of eagles in coastal Norway during winter, especially near offshore islands, when coastal fish tend to move to deeper waters. At least eight species of dabbling duck are known in
40425-440: The frigid weather. From Russia, breeding populations spill somewhat into northernmost Mongolia, extreme northwestern China and northern North Korea . The white-tailed eagle also breeds on Sakhalin Island , the Kuril Islands and Hokkaido, the northernmost island of Japan. The wintering range is less well understood for the white-tailed eagle given the extreme reductions and fluctuations of northern breeding populations over
40670-651: The hunting success rates on healthy birds can be low as revealed in studying wintering eagles in Sweden attempting to hunt mallards ( Anas platyrhynchos ). White-tailed eagles also regularly pirate food from otters and other birds including cormorants , gulls , ospreys , corvids and various other raptors . 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. From studies of captive white-tailed eagles, daily food requirements were estimated at 500 to 600 g (1.1 to 1.3 lb), which
40915-415: The imagination, it is often erroneously stated as the oldest Dutch sentence. Old Dutch naturally evolved into Middle Dutch . The year 1150 is often cited as the time of the discontinuity, but it actually marks a time of profuse Dutch writing; during this period a rich Medieval Dutch literature developed. There was at that time no overarching standard language ; Middle Dutch is rather a collective name for
41160-467: The influence of the Burgundian Ducal Court in Dijon ( Brussels after 1477). The dialects of Flanders and Brabant were the most influential around this time. The process of standardisation became much stronger at the start of the 16th century, mainly based on the urban dialect of Antwerp . The 1585 fall of Antwerp to the Spanish army led to a flight to the northern Netherlands, where the Dutch Republic declared its independence from Spain. This influenced
41405-461: The language of the Netherlands and Flanders. The word is derived from Proto-Germanic *þiudiskaz . The stem of this word, *þeudō , meant "people" in Proto-Germanic, and *-iskaz was an adjective-forming suffix, of which -ish is the Modern English form. Theodiscus was its Latinised form and used as an adjective referring to the Germanic vernaculars of the Early Middle Ages . In this sense, it meant "the language of
41650-417: The largest living birds of prey. It is the largest of the dozen species of eagle found in Europe and the largest eagle across its distribution, excluding the Russian Far East and (during the winter) Hokkaido, Japan, where it co-exists with its larger cousin, Steller's sea eagle. The white-tailed eagle is sometimes considered the fourth largest eagle in the world and is, on average, the fourth heaviest eagle in
41895-457: The largest males perhaps the heaviest recorded modern male eagle, as male harpy and Philippine eagles (being more sexually dimorphic in favour of the female) are not known to exceed 5 kg (11 lb) (the highest weights for male Steller's sea eagle are not known). The global mean body mass of white-tailed eagles is estimated at approximately 5 kg (11 lb). The average female Steller's sea eagle may weigh just under 25% more than
42140-464: The largest seabirds they encounter, such as great cormorants ( Phalacrocorax carbo ), and in some cases, such as in the Baltic Sea, have nearly destroyed whole colonies, from the eggs to the adults which average about 2.57 kg (5.7 lb). In the Estonian island of Hiiumaa , home to at least 25 pairs of sea eagles, as many as 26 individuals have been observed simultaneously culling a single cormorant colony. Similarly large numbers were taken of
42385-421: The largest talon on all accipitrids, is 37 to 46 mm (1.5 to 1.8 in) in length, averaging 40.9 mm (1.61 in). The hallux claw averages about a centimeter less than that of a golden eagle and is more sharply curved, an adaptation to prevent escape of slippery prey such as fish, while that of a bald eagle is similarly about 40.4 mm (1.59 in) and of similar curvature. The exposed culmen
42630-454: The largest wingspan of any living eagle. The Steller's sea eagle, which is larger in weight, total length and non-wing standard measurements, may be the closest rival for median wingspan amongst living eagles. The white-tailed eagle does appear to outsize the average wingspan of the wedge-tailed eagle ( Aquila audax ), which is sometimes also titled the largest winged extant eagle due to an exceptionally large individual shot in 1931, although
42875-402: The last call ended with a lower ko-ko-ko , the perched call of females is similar but deeper, a krau-krau-krau-uik-ik . Typically, the perched version of their calls tend to be shriller and higher than those issued in flight. In courtship display, male calls krau-krau-krau-uik-ik-ik answered by females with a lower ra-rack-rack-rack-rack . Young in nest call a shrilly piieh-piieh , while
43120-436: The last few centuries, so that the delineation of regular wintering areas versus areas of mere vagrancy is difficult to ascertain. It is known that a small number winter on Etang de Lindre of Lorraine , France as well as an area on the border of France to Germany around Strasbourg , with vagrants to elsewhere in France, as well as to Spain , Portugal and Malta . A well-defined wintering population may occur in much of
43365-476: 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 . A recent genetic study of mitochondrial DNA is consistent with this idea. Greenlandic white-tailed eagles (proposed as H. a. groenlandicus ) form, on evolutionary time scales, a relatively recently founded population that has not yet accumulated many unique genetic characteristics and may not strictly fulfill
43610-555: The leading prey species is the salmonid, the Arctic char ( Salvelinus alpinus ), which comprised 27.2% of 660 prey items. The secondary prey in Greenland was recorded as two species of cod . While the average weight of cod taken here was estimated at only 420 to 640 g (0.93 to 1.41 lb) and the average char at 660 to 740 g (1.46 to 1.63 lb), The eagles occasionally brought larger individuals up to 2.2 kg (4.9 lb) for cods and up to 3.2 kg (7.1 lb) for chars respectively. In Norway, of 524 fish prey items,
43855-512: The least (adults 15%, children 1%). The decline of the West Frisian language in Friesland occupies a middle position (adults 44%, children 22%). Dialects are most often spoken in rural areas, but many cities have a distinct city dialect. For example, the city of Ghent has very distinct "g", "e" and "r" sounds that greatly differ from its surrounding villages. The Brussels dialect combines Brabantian with words adopted from Walloon and French . Some dialects had, until recently, extensions across
44100-417: The length (but perhaps not the girth) of the truly massive bill of the Steller's sea eagle. The adult white-tailed eagle is a greyish mid-brown colour overall. The plumage is fairly uniform over most of the body and wings, but the upper wing coverts are typically somewhat paler. In the adult, the head, neck and upper breast have a distinctly paler appearance than the rest of the plumage and most often have
44345-443: 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 ~3,500-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,
44590-440: The mallard's flightlessness during eclipse plumage may result in eagles hunting them intensely only in late summer. Due to this mallards are usually a secondary prey species year around. The largest known representation of mallards in the diet were from Müritz National Park in Germany, where mallards were the third best represented prey species at 10.1% of 247 items and from Augustów Primeval Forest in Poland, where mallards were
44835-413: The mantle, back and upper wing. The head of the juvenile is normally a blackish-brown hue, somewhat darker and always more uniform than most of the other feathers. The juvenile's tail tends to be a washed out greyish-cream colour with messy blackish colour on the feather edges and on the tips. Some individual juveniles may exhibit some faint barring on the tail while others may appear largely dirty whitish on
45080-481: The most complete picture attainable. During winter, mammal prey can become more important in foods locally, as indicated in Scotland and shown in Norway and eastern Germany. As much as 41% of the diet can be made up of mammals, as was the case on the Kola Peninsula . There is evidence of strong seasonal shifts in food habits in several parts of the range, usually the largest portions of fish are caught during warmer months while birds and mammals are more important in
45325-411: The most diverse group in their prey spectrum. While hunting birds, this massive, relatively slow-flying eagle requires an element of surprise, with often a tactful use of cover or bright sunlight upon the approach from a nearby perch. For example, grey herons ( Ardea cinerea ) have been caught after an eagle used a low flight over turbulent water to ambush them. However, even with a stealthy attack,
45570-402: The northern part of the Caspian Sea and some central and southern parts of Kazakhstan, the white-tailed eagle may (or may not) live alongside the rarer, relatively poorly-known Pallas's fish eagle . The Pallas's juveniles are more distinctively whitish marked on the underwing. In flight or perched, the Pallas's fish eagle are usually markedly smaller and slighter than white-tailed eagles with
45815-457: The northwest of the Netherlands , past the great river estuaries of Germany to its northern boundary at Skallingen in Denmark along a total coastline of some 500 km (310 mi) and a total area of about 10,000 km (3,900 sq mi). Within the Netherlands, it is bounded from the IJsselmeer by the Afsluitdijk . Historically, the coastal regions were often subjected to large floods, resulting in thousands of deaths, including
46060-424: The number of North Atlantic humpback whales and minke whales might have resulted in more visits and possible re-colonization by the species to the areas especially around Marsdiep . Future recovery of once-extinct local bottlenose dolphins is also expected. A number of human-introduced invasive species , including algae , plants, and smaller organisms, are causing negative effects on native species. Each of
46305-502: The oldest single "Dutch" words, the Bergakker inscription yields the oldest evidence of Dutch morphology. However, interpretations of the rest of the text lack any consensus. The Franks emerged in the southern Netherlands ( Salian Franks ) and central Germany ( Ripuarian Franks ), and later descended into Gaul . The name of their kingdom survives in that of France. Although they ruled the Gallo-Romans for nearly 300 years, their language, Frankish , became extinct in most of France and
46550-513: The original language of the Franks. However, the language did experience developments of its own, such as very early final-obstruent devoicing . In fact, the find at Bergakker indicates that the language may already have experienced this shift during the Old Frankish period. Attestations of Old Dutch sentences are extremely rare. The language is mostly recorded on fragmentary relics, and words have been reconstructed from Middle Dutch and loan words from Old Dutch in other languages. The oldest recorded
46795-464: The planet. The word wad is Frisian and Dutch for "mud flat" ( Low German and German : Watt , Danish : Vade ). The area is typified by extensive tidal mud flats , deeper tidal trenches ( tidal creeks ) and the islands that are contained within this, a region continually contested by land and sea. The landscape has been formed for a great part by storm tides in the 10th to 14th centuries, overflowing and carrying away former peat land behind
47040-415: The predominant colloquial language out of the area's 22 million Dutch-speakers. Limburgish , spoken in both Belgian Limburg and Netherlands Limburg and in adjacent parts in Germany, is considered a dialect in Belgium, while having obtained the official status of regional language in the Netherlands. Limburgish has been influenced by the Ripuarian varieties like the Colognian dialect , and has had
47285-763: The prey spectrum. Due to the social inclination of dabbling ducks, they perhaps have the most success hunting isolated birds but they've also been taken from panic-stricken flocks as well. Despite the difficulty of taking them, dabbling ducks of unidentified species were found to be the main food of white-tailed eagles in Lake Baikal , where they comprised 51.8% of 199 prey items. In Fennoscandia , they are attracted to coastal waters during winter to attack large numbers of diving ducks including eiders, common goldeneye ( Bucephala clangula ), goosander ( Mergus merganser ) and red-breasted merganser ( Mergus serrator ), tufted ducks ( Aythya fuligula ) and scoters . Year around in Åland , 66.2% of 5161 food items were birds, while in
47530-620: The primary position in the diet. From 26 accumulated food studies for this species, prey remains and pellets show that about 48.5% of the diet is made up of birds, 39.95% by fish, 9.95% by mammals and 1.6% by other foods. In total, more than 300 prey species are known throughout the bird's range. However, based on studies of prey remains and pellets in laboratories from Greenland white-tailed eagles, birds were shown to be biased in both kinds of remains (pellets and prey remains) whereas in situ study and direct nest observation favour fish. Going on pellet/remains alone here in Greenland from 557 items in
47775-411: The provinces of Gelderland , Flevoland , Friesland and Utrecht . This group, which is not Low Franconian but instead Low Saxon and close to neighbouring Low German, has been elevated by the Netherlands (and by Germany) to the legal status of streektaal ( regional language ) according to the European Charter for Regional or Minority Languages . It is regarded as Dutch for a number of reasons. From
48020-422: The rapidly increasing Danish population have found that when well-protected, they may regularly forage in habitats near significant humans populations, even in the outskirts of cities, and they can also successfully breed in such locations. White-tailed eagles spend much of their day perched on trees or crags, and may often not move for hours. Perhaps up to 90% of a day may be spent perched, especially if weather
48265-548: The reintroduced birds of Scotland of Norwegian stock) 4.98 kg (11.0 lb) in 39 males and 6.06 kg (13.4 lb) in 43 females. In comparison, the weight ranges for white-tailed eagles from Northeast China were claimed to be only 2.8 to 3.78 kg (6.2 to 8.3 lb) in males and 3.75 to 4.6 kg (8.3 to 10.1 lb) in females. The heaviest female white-tailed eagles can apparently weigh as much as 7.5 to 8 kg (17 to 18 lb) and even males can sometimes weigh up to 6.5 kg (14 lb), which would make
48510-423: The rights of Dutch speakers, mostly referred to as "Flemish". However, the dialect variation was a serious disadvantage in the face of the standardised francophony . Since standardisation is a lengthy process, Dutch-speaking Belgium associated itself with the standard language that had already developed in the Netherlands over the centuries. Therefore, the situation in Belgium is essentially no different from that in
48755-462: The same branch of the West Germanic languages as Old English (i.e. Anglo-Frisian ) and are therefore genetically more closely related to English and Scots than to Dutch. The different influences on the respective languages, however, particularly that of Norman French on English and Dutch on West Frisian, have rendered English quite distinct from West Frisian, and West Frisian less distinct from Dutch than from English. Although under heavy influence of
49000-413: The sea eagles include Accipiters , harriers , chanting-goshawks and buteonines . Notably excluded from their relations are most other species referred to as "eagles", including booted eagles and snake and serpent eagles . The white-tailed eagle itself 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
49245-425: The second most numerous prey and made up 9.84% of 803 items. Taken more preferentially where they occur are common eiders. When hunting eiders, perhaps the largest of diving ducks at a mean weight of 2.06 kg (4.5 lb), white-tailed eagles frequently force the eider to dive repeatedly until it is exhausted and can be captured. When sitting on the nest, the female common eider will try to escape in flight but
49490-518: The second most often recorded prey species in both Müritz National Park (Germany), where they made up 16.42% of 247 prey items, and in Austria, where they made up 9.5% of 349 items. They will take many goslings during summer, as greylag goslings alone can comprise up 23% of the seasonal bird prey. Fully-grown greylag geese up to 4 kg (8.8 lb), especially infirm individuals are also taken in other seasons. White-tailed eagles are also known to attack and prey on other geese, ranging in size from
49735-584: The sexes are rarely this discrepant in standard measurements. Among standard measurements, the wing chord is 552 to 695 mm (21.7 to 27.4 in) in males, averaging 606 and 645 mm (23.9 and 25.4 in) in European adults and juveniles, respectively, and 646.5 mm (25.45 in) in Greenland males. In females, the wing chord may measure 605 to 740 mm (23.8 to 29.1 in), averaging 668 and 685 mm (26.3 and 27.0 in) in European adults and juveniles, respectively, and 691.3 mm (27.22 in) in Greenland females. Adult tail length
49980-407: The short summers ), northern and western Iceland , and the reintroduced populations in some areas of England (re-established in 2019 ), Ireland and Scotland, particularly conserved coastal spots. In mainland Europe the range is expanding, with Europe's largest population breeding in coastal Norway (broadly), northern and southwestern Finland , eastern Sweden , broadly in Denmark , islands of
50225-417: The size of the bird". The male call is oft transcribed as gri-gri-gri or krick-krick-krick , while the female is a deeper gra-gra-gra-gra or krau-krau-krau-krau . These will increase in tempo and pitch, with about 15–30 calls in a sequence. Often pairs will duet during early spring, in flight or from a perch. When perched, the male calls kyi-kyi-kyi-kli-kliek-yak with the head thrown back and upwards in
50470-492: The slighter, more angular skull possessed by males. In disposition, the male juveniles are said to be more highly strung and higher voiced than their female counterparts. The head gradually grows paler over several years. The whitish mottling may increase on the upperparts, belly and especially on the underwing area later into their third year (considered the first subadult plumage) and subadult birds can appear fairly blotched with white but much individual variation in colouring
50715-535: The southwesterly direction to the shores of the Baltic Sea. One from Finland was recovered 520 km (320 mi) west in northern Norway and another was found as far south as Bulgaria. In more southerly areas, winter movements are drawn-out and irregular, with most mature pairs probably never leaving their nesting haunts year-around. Those that breed on inland waterways may migrate to sea coast. German juveniles usually do not travel far, with most recorded to travel less than 50 km (31 mi) from their nests and
50960-448: The species appear to take different migratory routes in autumn and spring, traveling from north-central Kamchatka thru the Kurile islands to Hokkaido in autumn, while in spring these eagles travel north through Sakhalin and the Okhotsk Coast . In the White Sea area, southward moments begin in September with most white-tailed eagles being gone by November but in mild winters some adults may remain behind. Some white-tailed eagles from
51205-423: The species live largely as scavengers, usually by coming across available carrion or watching for the activity of corvids , vultures or other raptors. White-tailed eagles in northeastern Germany were shown to hunt mostly from perches, in a "sit-and-wait" style, usually from a prominent tree perch. Like other sea eagles, they can only capture fish normally in the littoral zone , seldom hunting fish when they exceed
51450-512: The sun's eye.' The white-tailed eagle is a member of the genus Haliaeetus , a monophylic group comprising 11 living species, including the closely related Ichthyophaga fish eagles which may or may not be part of a separate genus. The latter group, comprising the lesser ( Haliaeetus humilis ) and the grey-headed fish eagle ( Haliaeetus ichthyaetus ), differ mostly in life history, being more fully devoted to fish eating and habituating wooded areas, especially in mountainous areas. In appearance
51695-410: The survival of two to three grammatical genders – albeit with few grammatical consequences – as well as the use of modal particles , final-obstruent devoicing , and (similar) word order . Dutch vocabulary is mostly Germanic; it incorporates slightly more Romance loans than German, but far fewer than English. In Belgium, the Netherlands and Suriname, the native official name for Dutch
51940-404: The tail colour is similar at the various stages of development but the shape is more distinctive, especially the bolder wedge shape of the Steller's. The cinereous vulture ( Aegypius monachus ) may too be considered superficially similar to the juvenile white-tailed eagle, but it is considerably larger and longer-winged and possesses a more uniform and darker hue with conspicuous paler legs and
52185-399: The tail. The bill of juveniles is usually almost half dark brown from the tip and half dirty, dull yellowish or grey to the base, while the feet are usually a dirty yellow and the eyes are a darkish brown. Juvenile males may average a slightly darker brown plumage with less speckling on the upper body than like-age females; their head and neck plumes may also appear shorter, which can accentuate
52430-404: The term " Diets " was revived by Dutch linguists and historians as well, as a poetic name for Middle Dutch and its literature . Old Dutch can be discerned more or less around the same time as Old English (Anglo-Saxon), Old High German , Old Frisian , and Old Saxon . These names are derived from the modern standard languages . In this age no standard languages had yet developed, while
52675-514: The three countries has designated Ramsar sites in the region (see Wadden Sea National Parks ). Although the Wadden Sea is not yet listed as a transboundary Ramsar site, a great part of the Wadden Sea is protected in cooperation of all three countries. The governments of the Netherlands, Denmark and Germany have been working together since 1978 on the protection and conservation of the Wadden Sea. Co-operation covers management, monitoring and research, as well as political matters. Furthermore, in 1982,
52920-479: The three sites in different parts of Finland birds made up 51.1% of 3152 food items. In Germany, 52.4% of 1637 prey items were birds, mostly coots and unidentified waterfowl. More locally in Germany, in Müritz National Park the percentage of birds in the diet climbs to 65.73% Birds were strongly dominant in food records from Scotland, making up 73.53% of 1930 prey items, and in Kandalaksha Nature Reserve , where they comprised 75% of 523 prey items. While most of
53165-447: The tip in flight and the white-tailed eagle is well known to soar extensively. This species can be surprisingly maneuverable on the wing, usually during aerial displays or dogfights with other birds. These eagles may also maneuver by half-closing both wings or fully closing one wing. The white-tailed eagle is considered a vocal bird of prey during the breeding season, although some authors consider their voice "not loud or impressive for
53410-468: The two Ichthyaetus are slenderer, longer tailed and more uniform and grey in colour than typical sea eagles. This species pair may not be genetically distinct enough to warrant division into separate genera. Other than these Ichthyophaga -type species found farther north in Asia, Sanford's sea eagle ( Haliaeetus sanfordi ) of the Solomon Islands is the most atypical Haliaeetus , retaining rufous-brown plumage into adulthood (this particularly resembling
53655-535: The two species. The white-tailed eagle does have a significantly larger wing chord and average wingspan than the bald eagle, but the latter usually possesses a longer tail, resulting in a larger total length than the white-tailed eagle and a larger mean tarsal length. Size variation is generally a clinal trend and is normally quantified using standard measurements such as wing, tail and tarsal length, or body mass, rather than wingspan or total length. As expected for many widely distributed animals of varied lineages,
53900-420: The urban dialects of the province of Holland . In 1637, a further important step was made towards a unified language, when the Statenvertaling , the first major Bible translation into Dutch, was created that people from all over the new republic could understand. It used elements from various, even Dutch Low Saxon , dialects but was predominantly based on the urban dialects of Holland of post 16th century. In
54145-469: The water to the nearest bank or shore. While this would leave them waterlogged, of course, the food yield from such a catch is obviously attractive. White-tailed eagles have been photographed doing this with a large fish successfully in Greenland and 35 such cases were reported in Norway alone. The most frequently recorded prey species in 18 food studies from across the range is the northern pike ( Esox lucius ), present in at least 16 of those studies. Pike
54390-525: The water's surface. Therefore, lurking benthic fish such as lumpsuckers are more vulnerable than many. Besides vulnerability, habitat, and prey behavior, fish body size may be a driver in the piscivore's dietary preferences. White-tailed eagles usually can take various fish from 0.1 to 8 kg (0.22 to 17.64 lb), but fish ranging 0.5 to 3 kg (1.1 to 6.6 lb) typically preferred. Similarly, studies have indicated that fish less than 20 cm (7.9 in) are taken infrequently, since they have
54635-435: The western coast to the north of the Low Countries, and influenced or even replaced Old Saxon spoken in the east (contiguous with the Low German area). On the other hand, Dutch has been replaced in adjacent lands in present-day France and Germany. The division into Old, Middle and Modern Dutch is mostly conventional, since the transition between them was very gradual. One of the few moments when linguists can detect something of
54880-517: The western part of its range, with eagles even breeding as far north as Greenland, Iceland and coastal Norway not moving at all for winter, but for some southward juvenile movements following dispersal. Juveniles overall are more migratory and dispersive and leave natal areas sooner, which is by August–September in northwestern Europe and return later, by March/April, than adults do. Few Norwegian juveniles, per banding studies, were recorded to travel any considerable distance. Extreme cases include one that
55125-622: The white-tailed eagle and tends to be more dashing in flight, which is usually done with a distinct dihedral. When perched, the golden eagle looks more sleek and compact than the rangier white-tailed eagle and tends to be a darker, richer hue of brown. Golden eagles have a much shorter neck, with a smaller head and bill and a longer, squarer tail. White wing patches of juveniles are also differently distributed in golden than juvenile white-tailed eagles. This eagle breeds in northern Europe and northern Asia. Their range extends to as far west as southern Greenland (prevented from breeding further north due to
55370-453: The white-tailed eagle conforms to Bergmann's rule in that more northerly birds tend to outsize those found relatively closer to the Equator . Average size also decreases from west to east across its distribution. The largest white-tailed eagles appear to be found in Greenland , these being slightly larger than those from Ireland , Scotland and Scandinavia and notably larger than eagles from central Europe , especially in proportions of
55615-400: The white-tailed eagle's prey spectrum are the family Cyprinidae , of which more than 20 species are known to be predated including the common bream. Others taken with some preference may include salmonids and cod and their allies , both families known to obtain relatively large body sizes and occasional habituate shallow water, as well as lumpsuckers because they are benthic. In Greenland,
55860-559: The white-tailed eagle's range. White-tailed eagles can hunt fish in fresh or saltwater as well as those that prefer brackish water areas. However, they are restricted to taking fish in extremely shallow water, often by preference in water less than 1 m (3.3 ft) deep. Ideal fishing areas can be found in areas such as the Baltic Sea, where low coasts and archipelagos often have relatively shallow water. While healthy, large fish are often taken as well, white-tailed eagles often take out sickly, injured, or already dead fish. In some cases,
56105-537: The wing area. Those from the southerly portions of the breeding range, such as Asia Minor (principally Turkey ), southern Kazakhstan , and Korea Bay , appear to be the smallest-bodied population but there have been limited measurements and published weights known for these extremely sporadic and rare Asian populations of eagle. Furthermore, weights of fully grown eagles from Greenland are not known. Unlike many accipitrids, juvenile white-tailed eagles (and seemingly other sea eagles as well) are often of similar weight to
56350-591: The wing at a height of at least 200 m (660 ft). In Norway, plunge-diving is considered rare. At times they will also fish by wading into shallows, often from shores or gravel islands. The species will at times variously follow fishing boats , readily exploits commercial fisheries , stocked lakes , carp ponds and the like, and scavenges dead fish or fish-offal in a wide range of situations. When it comes to non-fish prey, it has been said that white-tailed eagles often hunt by flying low over sea coast or lakeshore and attempt to surprise victims. However,
56595-574: The wing shape of a white-tailed eagle but are far smaller and shorter winged and never bear a protruding head. Similarly, the eastern imperial eagle ( Aquila heliaca ) may suggest a white-tailed eagle in its flat wing profile and relatively large head and neck but is also visibly smaller with far less broad wings and a relatively longer tail. Like all Clanga and Aquila , both greater spotted and eastern imperial eagles should be obviously distinct from white-tailed eagles by plumage characteristics. The golden eagle usually appears slightly smaller than
56840-444: The winter. Other established wintering areas are known in Europe in west-central Italy , northern Austria, fairly broadly in southern Slovakia and northern Hungary and a few protected pockets of Southeast Europe apart from the portions in the north and east where they still breed. Intermittent forms of vagrancy and migration (most from eagles that breed in or disperse from Russia) are known to occur in several areas of Turkey,
57085-441: The world. The only extant eagle species known to be more massive in mean bulk are the Steller's sea eagle ( Haliaeetus pelagicus ), the harpy eagle ( Harpia harpyja ) and the Philippine eagle ( Pithecophaga jefferyi ). The white-tailed eagle measures anywhere from 66 to 94 cm (26 to 37 in) in total length with a typical wingspan of 1.78 to 2.45 m (5 ft 10 in to 8 ft 0 in). This species may have
57330-400: The year near large bodies of open water, including coastal saltwater areas and inland freshwater lakes , wetlands, bogs and rivers . It requires old-growth trees or ample sea cliffs for nesting, and an abundant food supply of fish and birds (largely water birds ) amongst nearly any other available prey. Both a powerful apex predator and an opportunistic scavenger , it forms
57575-537: The young and adults of 5.1 kg (11 lb) common cranes ( Grus grus ). The largest waterbirds species preyed upon are swans, including mute ( Cygnus olor ), whooper ( Cygnus cygnus ) and Bewick's swans ( Cygnus columbianus bewickii ). While cygnets and disabled birds (either by natural conditions such as ice or by human hunters) are at the greatest risk for eagle predation, white-tailed eagles have preyed upon even healthy adult swans up to 10 kg (22 lb). They are reported to have attacked and eaten
57820-536: Was comprised by fish, led by the common carp ( Cyprinus carpio ) and Prussian carp ( Carassius gibelio ). Similarly, in Podlaskie Voivodeship , Poland 55% of all the identified fish species brought to the nest were common carps, up to 2.1 kg (4.6 lb) in weight with the mean mass of 493 g (1.087 lb). However, there are reports that white-tailed eagles managed to catch extreme sizes of carps, up to 15 kg (33 lb)in weight. White-tailed eagles are known to prey on about 170 species of bird,
58065-469: Was found 720 km (450 mi) south of its nest near Karlstad , Sweden, another set of four colour-marked first-year juveniles were also recorded to turn up in southern Sweden but one was found down to the Wadden Sea in the Netherlands and it is likely that trickling down numbers of Norwegian post-dispersal juveniles have gone onto form much of the known Dutch white-tailed eagle population. In contrast, young from Finland and Sweden tend to distribute to
58310-419: Was found to affect breeding white-tailed eagles less so than it seemed to affect breeding black storks ( Ciconia nigra ). On the other hand, from studying wintering white-tailed eagles in partially or heavily disturbed wetlands in parts of the Netherlands shows that such areas cannot support the eagles for any long-term period and may only be visited for a day or two by individual eagles. Conversely, reviews of
58555-662: Was found to be the main prey species in both the Baltic Sea and Lapland in Sweden, at three breeding locations in Finland, in two studies from Germany, and in Belarus . The maximum representation of pike known was in Lapland, where they comprised 38.2% of 809 food items. While an average mature weight for a pike is around 1.4 kg (3.1 lb), white-tailed eagles often attack larger-sized pike, with an estimated average weight range of 2 to 5 kg (4.4 to 11.0 lb). The largest pike taken by white-tailed eagles were even estimated to weigh around 12 to 15 kg (26 to 33 lb). The next most widely reported fish prey species
58800-399: Was found with the disembodied feet of a white-tailed eagle still embedded in its back, presumed the eagle drowned after being overpowered and drug under only to rot off, leaving only feet. Since they do not have the waterproofing oils on the plumage of the more accomplished raptorial diver, the osprey ( Pandion haliaetus ), white-tailed eagles prefer not to get their feathers wet as it can take
59045-416: Was gradually replaced by the Dutch endonym Nederlands . This designation (first attested in 1482) started at the Burgundian court in the 15th century, although the use of neder , laag , bas , and inferior ("nether" or "low") to refer to the area known as the Low Countries goes back further in time, with the Romans referring to the region as Germania Inferior ("Lower" Germania). It
59290-413: Was largely static and hence while "Dutch" could by extension also be used in its earlier sense, referring to what today would be called Germanic dialects as opposed to Romance dialects , in many cases it was understood or meant to refer to the language now known as Dutch. In the Low Countries Dietsch or its Early Modern Dutch form Duytsch as an endonym for Dutch gradually went out of common use and
59535-445: Was placed on the World Heritage list by UNESCO . A minor boundary modification in 2011 added the Hamburg Wadden Sea National Park to the site, and the Danish part was added to in 2014. The state of Bremen , covering part of the Weser River estuary, is not participating. Conservation efforts are coordinated by the Common Wadden Sea Secretariat, seated in Wilhelmshaven . Many of the islands have been popular seaside resorts since
59780-413: Was replaced by later forms of the language throughout Luxembourg and Germany in around the 7th century. It was replaced in France by Old French (a Romance language with a considerable Old Frankish influence). However, the Old Franconian language did not die out at large, as it continued to be spoken in the Low Countries, and subsequently evolved into what is now called Old Low Franconian or Old Dutch in
60025-417: Was under foreign control. In the 19th century, the East Indies trade started to dwindle, and with it the importance of Malacca as a trading post. The Dutch state officially ceded Malacca to the British in 1825. It took until 1957 for Malaya to gain its independence. Despite this, the Dutch language is rarely spoken in Malacca or Malaysia and only limited to foreign nationals able to speak the language. After
