These birds live upon insects of all kinds, as well as fruit, seeds, and berries; they do incalculable mischief in the fields, and destroy great numbers of eggs during the spring--indeed, their murderous propensities would almost bear comparison with those of the Falcon, for they will not only attack small birds, but occasionally fall upon fowls, ducklings, or pheasants so suddenly that their victims are quite unprepared to act on the defensive. In Norway it is popularly supposed that the Magpie begins its nest on Christmas Day; with us the preparations for building are not made till the commencement of spring. The nest is placed at the summit of a tree, or in some countries, as we have said, upon the tops of houses, and is formed of twigs or dry leaves, covered with a thick layer of clay; within this is placed a bed of delicate fibres or hair, upon which the eggs are deposited; the structure is then protected from the attacks of an enemy by a roof of dry thorns or twigs, woven lightly together, but sufficiently strong to keep off intruders; the entrance to the nest is effected through a hole at the side. The brood consists of seven or eight eggs of a green colour, sprinkled with brown spots. In three weeks the young are hatched, and are fed by both parents on a great variety of insects, earthworms and snails, the greatest caution being employed to avoid discovery of the nest; and so attached are the parents to their offspring, that we have known a female continue to brood after having received a shot in her body. When taken young from the nest the Magpie becomes extremely tame, and, like others of its race, soon learns to imitate words and whistle tunes, without having been subjected to the operation of _tongue slitting_, popularly supposed to be necessary before these birds can be taught to speak; in spite of their docility they are, however, most troublesome creatures, and tales without number might be told of the mischief they have wrought by throwing suspicion on innocent people by their thievish propensities, for they seem to delight in abstracting any bright or glittering object that attracts their attention.

THE BLUE MAGPIE.

The BLUE MAGPIE (_Cyanopica Cookii_) is frequently met with in the southern and central parts of Spain, and a very similar species (_Cyanopica cyanea_) inhabits the Crimea, a large portion of Siberia as far as the Amur river, and the whole of China. These birds have been separated from other members of the family on account of the great difference of the tints of their plumage, which is so extremely beautiful that the European species is pre-eminent among its feathered relatives; in both the species under consideration the back is pale brownish grey, the throat and cheeks greyish white, and the wings, quills, and tail light blueish grey; the eyes are reddish brown, and the beak and feet black. The plumage of the young birds is paler, the black upon the head and the blue of the wings being almost imperceptible; the grey of the body is very dingy, and the wings are marked with two indistinct grey lines. The length of both species is thirteen and a half to fourteen inches, their breadth sixteen inches to sixteen and a half; the wing measures five and a quarter, and the tail eleven inches; the female is not quite so large as her mate.

All such districts of Southern and Central Spain as are covered with woods of oak-trees are frequented by the Blue Magpie in great numbers, but it is rarely seen in the eastern provinces, over which the oak is but sparsely scattered. These birds are also met with in North-western Africa, living everywhere in large flocks; they sometimes settle upon the houses, and have no hesitation in constantly seeking their food amongst the refuse of the busiest streets. In most of their habits they closely resemble the Common Magpie, and when exposed to danger exhibit so much cunning in evading pursuit as to render their capture a very difficult and wearisome operation. The _voice_ of the Blue Magpie is, however, quite unlike that of the member of its family with which we are all so familiar; its note is very prolonged, and when several pairs are chattering gaily to each other their tones rather resemble the lusty sounds produced by the Green Woodpecker than those of their congeners. In Spain this species does not commence its building operations until May, but in other countries is somewhat earlier in the preparations for its young; the nest, which resembles that of a Shrike, has an outer frame of dry branches, lined with blades of grass, shoots of plants, and similar materials, which are selected with great care. Many nests are built upon the same tree, a whole party taking up their residence at a short distance from each other, preferring under these circumstances their favourite elms or other lofty trees as affording the safest lodging for the young. The brood consists of from five to nine eggs: these are of a greenish yellow, mottled with indistinct patches of a deeper shade, and spotted or streaked with olive brown markings, which occasionally form a kind of wreath at the broad end.

The BLUE RAVENS (_Cyanocorax_), as they have been called, are a species of Jays which appear to form a connecting link between the Magpies and the Jackdaws. These birds inhabit South America, and are remarkable for the magnificence of their plumage; their powerful beaks are usually as long as the entire head, somewhat compressed towards the tip, slightly arched at the roof, and covered with bristles at the base; the wings, in which the fifth and sixth quills are longer than the rest, extend to the root of the long tail.

THE HOODED BLUE RAVEN.

The HOODED BLUE RAVEN (_Cyanocorax pileatus_) is about fourteen inches in length, seventeen broad, with wings six inches, and tail six and a half inches long. The forehead, bridles, and upper part of the head (the feathers of which are considerably elongated), are of a rich black, so are the sides of the neck and the entire throat; the nape, back, wings, and tail, bright blue, and the entire lower part of the body white, as are also the tips of the feathers that compose the tail; above and below the eyes is a broad, crescent-shaped spot of sky blue. Schomburghk tells us that these beautiful birds frequent high trees, and subsist upon fruit or seeds; they are very shy and restless, and are easily discovered through the constant utterance of their discordant cry. The nest, which is artistically constructed, is built at the summit of a lofty tree. The eggs, two in number, are brownish white, spotted with brown. Beyond these few facts we know nothing of the Hooded Blue Raven in its native haunts.

THE CRESTED BLUE JACKDAW.

The CRESTED BLUE JACKDAW (_Cyanocitta cristata_) is an American species, with which we are much better acquainted. The shape of this bird is slender, its beak short, strong, slightly arched, and pointed; the wings are short, their fourth and fifth quills longer than the rest; the tail long and decidedly rounded. The plumage is soft and brilliant, and the feathers upon the head prolonged into a crest. In the male the predominating colour upon the back is bright blue; the tail-feathers are surrounded by a narrow dark line, the wing-feathers are tipped with black; the ends of the secondary quills, the larger feathers of the wing-covers, and the exterior tail-feathers are white, or of a greyish-white shade; the sides of the head are pale blue; a line which commences at the back of the head and passes round the throat is black, as is also a streak between the eyes; the eye itself is greyish brown, the beak and feet blackish brown. This species is about eleven inches long, its breadth sixteen inches, the wing five inches and a quarter, and the tail five inches.

Notwithstanding the beauty of its appearance, the Blue Jackdaw is regarded with but little favour in America, where it is found in great numbers occupying the dense woods or groups of moderately high trees. It is only migratory from the Northern States, and is elsewhere numbered among the stationary birds. Wilson calls this species the _Bird Trumpeter_, from the remarkable sound that it produces when alarmed; and we learn from other writers that it can imitate the cry of the Buzzard and Sparrow Falcon to such perfection as frequently to terrify the smaller feathered denizens of the woods, and raises such an uproar on perceiving a fox or other enemy as compels the intruder to sneak quietly away. Its attacks upon the eggs and young of other birds are extremely merciless; and, indeed, it may be regarded as a most voracious and destructive bird of prey, which devours not only small quadrupeds, but will attack very large and powerful members of the feathered tribe should they be wounded, and thus for the time incapable of resistance; yet Audubon tells us that the Blue Jackdaw is a most arrant coward, and that it will often fly before an adversary no stronger than itself. It obtains its prey rather by extreme craft than by open warfare, for even Thrushes and other small birds can scare it from their nests, into which, however, it often manages to steal if left unguarded only for a moment; it will also attempt to seize young chickens, but is at once baulked of its purpose if startled by an angry cluck from the hen. Large quantities of seeds, all kinds of insects, and flesh are also eaten by these birds. During the autumn the maple, oak, and other similar trees are thickly covered by swarms of Blue Jackdaws, who not only satisfy their present wants, but carry off large quantities of seeds or acorns, storing them up as a provision for the winter, and by this means greatly assist in spreading the growth of these trees over the face of the country.

The number of broods varies with the district in which the Jackdaws are found, some breeding but once and others twice in the year; the nest is formed of twigs and other dry materials, lined with a bed of delicate fibres, on which, in due season, four or five eggs are deposited; these latter are olive brown, marked with dark spots. During the time that the mother is sitting the male employs every precaution to prevent the discovery of his young family; he visits his mate with the utmost secrecy, and preserves the strictest silence while in her company. The young are fed principally upon insects. Nestlings may be easily reared in confinement, but it is never safe to trust the Blue Jackdaw in an aviary with other birds, as it is not uncommon, under these circumstances, for it to destroy its companions one after another. Audubon gives a most interesting account of an attempt he made to naturalise this species in Europe, but which unfortunately proved abortive; the birds, about thirty in number, destined to make the experiment were placed by him in a large cage, and at first exhibited every symptom of fear, refusing the food he proffered them, and crouching in the corners of the cage; by the next day, however, all had regained their usual spirits, and, taking up seeds of maize in their claws, hammered at them with such hearty good will that the noise they produced sounded more like a diminutive party of smiths than the efforts of birds; quarrels seldom occurred, and the party reached Europe in excellent health and spirits, but had not been long exposed to the change of climate before they began to be infested by numerous parasites, and only one survived to reach London. Since this attempt of the American naturalist many Blue Jackdaws have been brought to Europe, but in no instance have the efforts to naturalise them proved successful.

THE COMMON JAY.

The COMMON JAY, or OAK JACKDAW (_Garrulus glandarius_), is an European species, bearing no inconsiderable resemblance to the American bird above described, but its beak is stronger, and the tail shorter and less rounded. The plumage is silky, lax, and flowing, the feathers upon the head being prolonged into a crest. Its colour is principally greyish red or greyish brown, darker upon the back than on the lower parts of the body; the rump is white, the throat whitish, and marked upon its upper portion by two broad black streaks, commencing on the cheeks; the forehead is speckled with black and white; the quills are black, with the exception of a greyish-white space upon the outer web; the tail-feathers are black, occasionally edged with blue; the covers over the primary quills are striped alternately with blue, black, and white, producing a very lustrous effect. The eye is light blue, the beak black, and the feet horn colour. The length of this species is about thirteen, and its breadth twenty inches; the wing measures six and a half, and the tail five inches and three-quarters. The female is somewhat smaller than her mate.

A species closely related to this bird, but differing from it in the markings of the head, is occasionally met with in the south-eastern parts of Germany; its actual habitat, however, is North-western Asia, and members of the group to which it belongs are found in Central and Northern Asia. The Jay inhabits all the wooded districts of Europe except its northern parts, and is also met with in Central Asia and Western Africa; in Germany it is exceedingly common, but in England somewhat scarce. This bird frequents pine forests, woodland pastures, or leafy groves with equal impartiality, living during the summer in pairs, but at other seasons of the year flying over the country with its companions in small parties; it seems to avoid localities where there are no oak-trees, such districts being rarely visited. The Jay is extremely restless, and though in some respects a lively and interesting bird, is so crafty as to render it at times very troublesome, not only to its feathered associates, but to man. When excited, it places itself in a succession of strange attitudes, and imitates a great variety of sounds with amusing correctness. Whilst in a tree, its movements are light and active, and its gait upon the ground by no means awkward; but its flight is heavy, and it rarely remains for any length of time in the air, preferring to perch at short intervals upon trees or bushes, using them, however, not merely as resting-places, but as temporary shelter from the numerous feathered enemies by whom it is constantly pursued in the course of its short excursions from one wood to another. Naumann describes the dread in which many birds of prey are held by the Jays as so great, that they rarely venture to congregate in large flocks, but fly apart over the open country, living according to the advice of the old French maxim, "Chacun pour soi." The wonderful power possessed by this species of imitating the voices of other birds is noticed by many writers. Naumann heard a Jay whinny like a foal and crow like a cock; and Rosenberg tells us that late in the autumn, when seated beneath a tree, he heard one successively imitate the voices of the Magpie, the Shrike, the Thrush, and the Starling, and that on searching the branches to obtain a sight of such unseasonable vocalists, he discovered that all these various sounds were produced by a Jay, perched on a bough just above his head.

Of this bird it may be said, in the broadest sense of the word, that it will eat anything it is possible to obtain or vanquish; nothing, from a mouse to the smallest insect, escapes its voracity. During the autumn it often subsists for weeks together upon acorns and birch or hazel nuts, softening the former in the crop, and afterwards tearing off the shell with its beak; the latter it breaks by hammering upon them without any such preparatory process; Naumann also mentions having seen one of these birds in the act of killing a Thrush, and adds that they frequently work great destruction among young Partridges. The period of incubation commences early in the spring; the nest, which is by no means large, is placed in the branches of a tree at very various heights from the ground, and formed of dry stalks or small twigs, neatly lined with fibrous roots. The eggs, five to six in number, are laid about April; they are of a dirty white, thickly marked with greyish-brown streaks and spots, some of which form a wreath around the broadest end. Only one brood is produced during the year. The young nestlings leave the shell in about sixteen days, and are fed at first on caterpillars, larvæ, worms, and a variety of insects, but at a later period are reared upon the flesh of young birds. Falcons and Sparrow-hawks are among the many enemies with which the Jay has to contend; by the former it is immediately vanquished, but with the latter it will sometimes struggle long and fiercely, the combatants not unfrequently falling to the ground, exhausted by the violence of their efforts. The Horned Owl is a still more formidable assailant, destroying many birds belonging to this species; and their nests are constantly sacked by the Tree Martin, whose approach is often greeted with the most appalling cries as the parents attempt to drive the destroyer from their young. In its intercourse with man the Jay is extremely wary, and often succeeds in exasperating the sportsman, as, while in safety itself, it derides his efforts by its cries, and at the same time warns the other denizens of the wood that danger is approaching. If taken young, these birds may be trained to utter words, but their many disagreeable propensities render them even more unfit for a life of confinement than their American congeners.

* * * * *

In the more northern countries of Europe where the Common Jay is not met with, we find it replaced by a species whose delicate beak, decidedly rounded tail, and dusky plumage, have caused it to be regarded as the representative of a distinct group.

THE UNLUCKY JAY.

The UNLUCKY JAY (_Perisoreus infaustus_) is about twelve inches long and eighteen broad; its wing and tail measure five and a half inches. The prevailing colour of the adults is a light reddish grey, the quills and centre tail-feathers are grey, while upon the wings and the exterior tail-feathers there are patches of reddish brown; the upper part of the head is blackish brown. Young birds are known by the comparative paleness of their tints, and the indistinct markings upon the lower portions of the body. The eyes are greyish brown, the beak and feet black.

The dense fir and pine forests of Russia and Siberia are in some places numerously inhabited by this species, which has been known to fly as far as Germany, and, though rarely, is occasionally seen in Norway and Lapland. In some respects it resembles the bird we last described, but its activity and intelligence are inferior, and its mischievous propensities by no means so conspicuous as in the Common Jay. Wilson tells us that it is so bold and inquisitive that it will perch upon the cap of the woodcutter when engaged at his work, and testifies so little fear of man as to follow flocks of reindeer to their resting-place, even when accompanied by their herdsman. Its gait upon the ground resembles that of the Jackdaw, but amongst the branches it is considerably more active in its movements. When perching upon a tree it often appears to be under no anxiety to conceal itself, and seems to trust to the inconspicuous colour of its attire as a sufficient protection from the eye of an enemy. The flight of the Unlucky Jay is unsteady and struggling, and its cry, which is composed of two syllables, has been compared to that of a man in distress; Schräder speaks of it as being not unlike that of the Shrike, composed of various hoarse notes, mingled with sounds resembling the mewing of a cat. Nuts, berries, seeds, acorns, and insects of all kinds are eagerly sought after by these birds; they will climb amongst the fir and pine trees like Titmice, to obtain the contents of the cones, in very much the same manner as that practised by the Cross-bills, and as winter approaches will lay up a goodly store of these provisions; but their hoards are frequently plundered by squirrels or woodpeckers who have managed to discover the secret of their hiding-place.

This species commences its building operations in March: a nest which we obtained was a large structure, formed externally of twigs, moss, grass, and strips of pine branches; the interior was lined with an extremely thick layer of hair and Ptarmigan feathers. The eggs are usually from five to seven in number, of a greenish white, thickly covered with irregular dingy spots of greenish grey or olive green. The attachment of these birds to their young is extreme; should a sportsman approach their nest, the parent will fly down, and hobble along the ground as though lame, in order to draw his attention from the little family, and should it succeed in luring him to a safe distance from the spot, will rise suddenly into the air, and return by a circuitous flight to the place from whence it came.

When a flock of these birds is discovered, their capture is accomplished with little difficulty, for they will never desert each other in a moment of danger, so that should one member of the party be taken the rest become an easy prey. The Unlucky Jays are commonly to be met with throughout the whole of the fur districts in North America, where they may be seen hovering about the encampments of the trappers during the whole season. According to the account of Captain Blackiston, their capture is sometimes accomplished in the following manner:--A man lays himself flat down, either in a boat or upon the ground, draws a cloth over his head and shoulders, stretches out his hand, in which he holds a scrap of dry meat, and quietly awaits the result; his purpose is soon accomplished, for down come the birds to attack the meat, when, just as they are about to give the first peck at the tempting morsel, the treacherous hand seizes upon them with an irresistible grasp.

* * * * *

The LONG-TAILED CROWS (_Glaucopes_) are distinguished by their powerful and moderately long beak, which is broad at the base and compressed towards the tip. The upper mandible is slightly arched, hooked at its extremity, and covered at the base with short velvety feathers. The wings are short, their fifth quill longer than the rest; the tail is long and graduated, the feet strong, and the tarsus longer than the middle toe. The coloration of the plumage is brilliant. Like the Jackdaws, these birds almost exclusively frequent thick forests, and closely resemble the foregoing groups in their habits; the few facts we give below apply equally to them and the following species.

* * * * *

The TREE MAGPIES (_Dendrocitta_) constitute a group of Jays inhabiting India. They are large birds, with short, compressed, and very decidedly arched beaks; short, abruptly rounded wings, of which the fifth and sixth quills are longer than the others; wedge-shaped, elongated tails, the two centre feathers extending far beyond the rest; and with tolerably strong or short feet. So entirely are these Tree Magpies to be regarded as Indian, that not more than one or two of the five species mentioned by Jerdon are met with in neighbouring countries. We select for description the Kotri of the Hindoos (_Dendrocitta rufa_), or, as we shall call it,

THE WANDERING MAGPIE.
