EAGLE (Fr. aigle, from the See also:Lat. See also:aquila)  , the name generally given to the larger diurnal birds of See also:prey which are not vultures; but the limits of the subfamily A quilinae have been very variously assigned by different writers on systematic See also:ornithology, and there are eagles smaller than certain buzzards . By some authorities the Laemmergeier of the See also:Alps, and other high mountains of •See also:Europe, See also:North See also:Africa and See also:Asia, is accounted an See also:eagle, but by others the genus Gypaetus is placed with the Vulturidae as its 790 See also:common See also:English name (bearded See also:vulture) shows . There are also other forms, such as the See also:South See also:American Harpyia and its See also:allies, which though generally called eagles have been ranked as buzzards . In the See also:absence of any truly scientific See also:definition of the See also:family Aquilinae it is best to leave these and many other more or less questionable members of the See also:group—such as the genera Spizaetus, Circaetus, Spilornis, Helotarsus, and so forth—and to treat here of those whose position cannot be gainsaid . True eagles inhabit all the regions of the See also:world, and some seven or eight See also:species at least are found in Europe, of which two are See also:resident in the See also:British Islands . In See also:England and in the Lowlands of See also:Scotland eagles only exist as stragglers; but in the See also:Hebrides and some parts of the See also:Highlands a See also:good many may yet be found, and their See also:numbers appear to have rather increased of See also:late years than diminished; for the foresters and shepherds, finding that a high See also:price can be got for their eggs, take care to protect the owners of the eyries, which are nearly all well known, and to keep up the stock by allowing them at times to See also:rear their See also:young . There are also now not a few occupiers of Scottish forests who interfere so far as they can to protect the See also:king of birds.' In See also:Ireland the extirpation of eagles seems to have been carried on almost unaffected by the prudent considerations which in the See also:northern See also:kingdom have operated so favourably for the See also:race, and except in the wildest parts of See also:Donegal, See also:Mayo and See also:Kerry, eagles in the See also:sister See also:island are almost birds of the pest . Of the two British species the See also:erne (Icel . (Ern) or See also:sea-eagle (by some called also the See also:white-tailed and cinereous eagle)—Haliaetus albicilla—affects chiefly the See also:coast and neighbourhood of inland See also:waters, living in See also:great See also:part on the See also:fish and refuse that is thrown up on the See also:shore, though it not unfrequently takes living prey, such as See also:lambs, See also:hares and rabbits . On these last, indeed, young examples mostly feed when they wander southward in See also:Lord See also:Breadalbane (d . 1871) was perhaps the first large landowner who set the example that has been since followed by others . On his unrivalled See also:forest of See also:Black See also:Mount, eagles—elsewhere persecuted to the See also:death—were by him ordered to be unmolested so See also:long as they were not numerous enough to cause considerable depredations on the farmers' flocks .

He thought that the spectacle of a soaring eagle was a fitting See also:

adjunct to the grandeur of his See also:Argyllshire See also:mountain scenery, and a good See also:equivalent for the occasional loss of a See also:lamb, or the slight See also:deduction from the See also:rent paid by his tenantry in consequence.autumn, as they yearly do, and appear in England . The adults (fig . 1) are distinguished by their prevalent greyish-See also:brown See also:colour, their See also:pale See also:head, yellow See also:beak and white tail—characters, however, wanting in the immature, which do not assume the perfect plumage for some three or four years . The eyry is commonly placed in a high cliff or on an island in a See also:lake—sometimes on the ground, at others in a See also:tree—and consists of a vast See also:mass of sticks in the midst of which is formed a hollow lined with Luzula sylvatica (as first observed by See also:John Wolley) or some similar grass, and here are laid the two or three white eggs . In former days the sea-eagle seems to have bred in several parts of England —as the Lake See also:district, and possibly even in the Isle of See also:Wight and on See also:Dartmoor . This species inhabits all the northern part of the Old World from See also:Iceland to See also:Kamchatka, and breeds in Europe so far to the southward as See also:Albania . In the New World, however, it is only found in See also:Greenland, being elsewhere replaced by the white-headed or bald eagle, H. leucocephalus, a See also:bird of similar habits, and the chosen See also:emblem of the See also:United States of See also:America . In the far See also:east of Asia occurs a still larger and finer sea-eagle, H. pelagicus, remarkable for its white thighs and upper wing-coverts . South-eastern Europe and See also:India furnish a much smaller species, H. leucory phus,which has its representative, H. leucogaster, in the See also:Malay See also:Archipelago and See also:Australia, and, as allies in South Africa and See also:Madagascar,H. vocifer and H.vociferoides respectively . All these eagles may be distinguished by their scaly tarsi, while the group next to be treated of have the tarsi feathered to the toes . The See also:golden or mountain eagle, See also:Aquila chrysaetus, is the second British species . This also formerly inhabited England, and a See also:nest, found in 1668 in the See also:Peak of See also:Derbyshire, is well described by See also:Willughby, in whose See also:time it was said to breed also in the See also:Snowdon range .

It seldom if ever frequents the coast, and is more active on the wing than the sea-eagle, being able to take some birds as they See also:

fly, but a large part of its sustenance is the flesh of animals that See also:die a natural death . Its eyry is generally placed and built like that of the other British species,2 but the neighbourhood of 2 As already stated, the site chosen varies greatly . Occasionally placed in a See also:niche in what passes for a perpendicular cliff to which See also:access could only be gained by a skilful cragsman with a rope, the writer has known a nest to within 10 or 15 yds. of which he rode or. a See also:pony . Two beautiful views of as many golden eagles' nests, See also:drawn on the spot by See also:Joseph See also:Wolf, are given in the Ootheca Wolleyana, and a See also:fine See also:series of eggs is also figured in the same See also:work . See also:water is not requisite . The eggs, from two to four in number, vary from a pure white to a mottled, and often highly coloured, See also:surface, on which appear different shades of red and See also:purple . The adult bird (fig . 2) is of a See also:rich dark brown, with the elongated feathers of the See also:neck, especially on the nape, See also:light tawny, in which See also:imagination See also:sees a " golden " See also:hue, and the tail marbled with brown and ashy-See also:grey . In the young the tail is white at the See also:base, and the neck has scarcely any tawny tint . The golden eagle does not occur in Iceland, but occupies suitable situations over the See also:rest of the Palaearctic Region and a considerable portion of the Nearctic—though the American bird has been, by some, considered a distinct species . Domesticated, it has many times been trained to take prey for its See also:master in Europe, and to this species is thought to belong an eagle habitually used by the See also:Kirghiz See also:Tatars, who See also:call it Bergut or Bearcoot, for the See also:capture of antelopes, foxes and wolves . It is carried hooded on See also:horse-back or on a See also:perch between two men, and released when the See also:quarry is in sight .

Such a bird, when well trained, is valued, says P . S . See also:

Pallas, at the price of two camels . It is quite possible, however, that more than one See also:kind of eagle is thus used, and the services of A. heliaca (which is the imperial eagle of some writers 1) and of A. mogilnik—both of which are found in central Asia, as well as in south-eastern Europe—may also be employed . A smaller See also:form of eagle, which has usually gone under the name of A. naevia, is now thought by the best authorities to include three See also:local races, or, in the eyes of some, species . They inhabit Europe, North Africa and western Asia to India, and two examples of one of them—A. clanga, the form which is somewhat plentiful in north-eastern See also:Germany—have occurred in See also:Cornwall . The smallest true eagle is A. pennata, which inhabits See also:southern Europe, Africa and India . Differing from other eagles of their genus by its See also:wedge-shaped tail, though otherwise greatly resembling them, is the A audax of Australia . Lastly may be noticed here a small group of eagles, characterized by their long legs, forming the genus Nisaetus, of which one species, N. fasciatus, is found in Europe . (A .
