Part 20

The Siskin seeks its mate in April, obtaining her favour by very much the same efforts as those practised by the Cross-bills, the male bird, at such times, looking much larger than it really is, spreading its wings, and wheeling around her at a considerable height in the air, and at the same time singing vigorously. During this courtship the female remains quite quiet, only from time to time caressing her companion with her beak, or making short excursions in his company. Occasionally many of these little couples will join company, and live in the utmost peace and unity. The building of the nests begins shortly after the pairing of the birds, and all must admire the cunning with which the female selects a suitable spot, and fully appreciate the popular idea that a Siskin's nest is invisible. The locality fixed upon is generally the extreme end of a thick, lofty branch, the foliage of which entirely conceals the little domicile. Fir and pine-trees are frequently selected for nidification, and so perfectly does the exterior of the nest resemble the branch upon which it is placed, that it is only recognisable when seen from above, in which position it is betrayed by its rounded interior--indeed, so completely is it hidden from observation, that a servant sent by us into a tree to discover the nest, was about to descend without it, even though it lay but two feet distant from him; and had we not recommended him to strip the branch by removing one twig after another, he probably would have sought for it in vain. This plan, however, succeeded, and the prize was secured. The skill with which these little creatures conceal their young has prevented any one from having seen the nest in progress of erection, and will account for the old-fashioned legend that the Siskin builds with invisible stones--for so very great is the difficulty of distinguishing these structures from the surrounding branches, that few naturalists have succeeded in finding them. The progress of the work is extremely rapid. The two birds that we saw laboured alternately, each waiting while the other supplied fresh materials, and then flew together in search of what more was required, bringing back beakfuls of dry twigs, wool, or moss, which they tore from the bark of the trees. It was curious to see the little creatures prepare the wool, with which the nest is lined, by holding it with the foot while pulling it out with their beak to render it soft and elastic. In some other instances that have come under our notice, the female alone constructed the nest, the male keeping near her during the whole time. When busy in the preparation of their dwelling, these little birds testify no uneasiness if watched or approached, though they have been known to leave a partially constructed nest, and commence another. The vicinity of water is always preferred in the choice of a tree on which to build. The nests vary considerably in their appearance. They are formed of twigs and moss, bound strongly together with cobwebs, and lined with feathers, hair, and various kinds of delicate fibres. The walls are very thick, and the central cavity deep. The breeding season usually commences about the beginning of June, but young fledged birds have been seen as early as May. The eggs, which resemble those of the Brown Linnet, differ remarkably from each other in size, shape, and colour, but are, for the most part, of a whitish-blue or blueish-green, marked with a variety of spots and veins. The female alone sits upon the eggs, remaining on the nest from the time that the first is laid. The Siskin has been known to breed in captivity.

THE GOLDFINCH.

The GOLDFINCH (_Carduelis elegans_) may be considered as the type of a group that has but few representatives, the only other species with which we are acquainted being an inhabitant of the West Indies. The Goldfinches are distinguished by their long, conical, compressed beak, bent slightly at the tip; short strong legs, tail of middle length, and variegated exterior. The feathers of both sexes are alike in their colouring, but the young bear no resemblance to the parents. The length of the male is about five inches, its breadth eight and three-quarter inches. The female is not quite so large. The tail measures two inches, and the wing two and a quarter inches from the shoulder to the tip. The plumage is most beautifully marked and ornamented (see Coloured Plate V.); the beak, which is flesh-coloured at the base and blue at the tip, is surrounded by a black circle, and this again is encompassed by a broader band of red. The back of the head and part of the otherwise white cheeks are black. The back is brown, the belly white; and the sides of the upper part of the breast light brown; the wings and tail black, streaked with white, and the quills golden yellow at the root. The two sexes are so much alike that it requires a practised eye to distinguish them, though the male has somewhat more red on the face and a deeper black upon the head than the female.

The Goldfinch inhabits a much larger extent of country than most others of its race, being found over the whole of Europe, in Madeira, the Canary Isles, North-western Africa, a large part of Asia, and even in Cuba. Districts rich in trees and plants are the favourite resorts of this bird, from whence it flies over the surrounding country in search of food, frequently visiting our fields and gardens, and enlivening us by its activity and beautiful song. When upon the ground, its movements are decidedly slow and awkward; but nothing can exceed its nimbleness in climbing, and it may often be seen hanging from a twig head downwards, for whole minutes at a time. Its flight, like that of its congeners, is light, rapid, and undulating; like them it hovers before perching. It generally prefers the highest branch, upon which it sits bolt upright, with plumage tightly compressed; but its restless disposition prevents it from remaining for any great length of time upon one spot. It is remarkably shy and peaceable in disposition, living upon excellent terms with its feathered brethren, but preferring the society of the Titmouse. The song of the male is loud and pleasing, and his voice may be heard throughout the whole year, except during the moulting season. These birds subsist upon various kinds of seeds, principally those of the thistle tribe, so that wherever the latter are found we may look for the presence of these pretty songsters; indeed, a more pleasing sight can scarcely be imagined than that of a party of Goldfinches, as they hang head downwards from the thistle tops, and rob them of their seeds by the aid of their long and pointed beaks. In this business the harsh, strong feathers upon the head are of great service, as they shield that part from the prickly mass from which they pluck their food. During the summer, they destroy large quantities of insects--indeed, upon these they feed their young, thus rendering inestimable service to mankind. The nest is built upon a tree at about twenty or twenty-four feet from the ground, and is so carefully concealed at the end of the branch upon which it is placed, as to be quite imperceptible until the leaves fall. The female alone works at its construction, employing moss and fibrous roots for the outer wall, and weaving these materials together in the most artistic manner with spiders' webs; the interior is then lined with thistle-down, which is kept in its place by the aid of horsehair or bristles. The male bird sings with great vigour while the work progresses, but rarely assists his mate in her labours. The brood consists of four or five delicate, thin-shelled eggs, of a white or blueish-grey colour, lightly sprinkled with violet grey spots, which form a kind of wreath at the broad end. The eggs are generally laid about May, and the parent birds breed but once during the summer. The female sits upon the nest for thirteen or fourteen days, never leaving her brood for more than a few moments; her mate brings such food as she requires, and subsequently assists her to feed the young for some time after they are fully fledged. The capture of Goldfinches is attended with but little difficulty, and, though shy, they are easily tamed, and taught a variety of pleasing tricks. They will pair with Canaries when caged, and the progeny have the colours of both parents most curiously blended in their plumage. The food of these birds, when tamed, should consist of seeds and an abundance of green-stuff; but whilst nestlings, they must be fed upon bread soaked in water, until their beaks have acquired a little strength.

THE GOLDEN THISTLE-FINCH.

The GOLDEN THISTLE-FINCH (_Astragalinus tristis_), an inhabitant of the New World, is an elegant creature, of about four and a half inches long and eight broad. This bird resembles our Goldfinch in its appearance, the yellow plumage being varied by a black and white bordering to its wings and tail-feathers. The beak and feet are brownish yellow, and the eyes dark brown; the coat of the female is deeper in its hues than that of her mate, and has no black spot on the forehead; in other respects it so exactly resembles its European congener, as to require no further description, and Audubon tells us that their voices are so similar as to be scarcely distinguishable.

THE SPARROWS PROPER (_Passeres_).

THE SPARROWS are known by their strong, thick, stunted beaks; short, stout legs, furnished with toes of moderate length and crooked claws; their wings are short, and the tail more or less graduated; the body is stoutly built, and the plumage simple in its colour and markings. The feathers of the male are of chestnut-brown, grey, or golden yellow, while those of the female are entirely grey, streaked with brown; the young are like the mother. The members of this family strongly resemble each other in their mode of life and habits; all are more or less stationary, frequenting agricultural districts, and any place inhabited by man; never going to a great distance from their dwelling-place, and passing their time principally upon the ground in search of food. The Sparrows show as great a dislike to barren districts, as to thick woods; preferring such spots as are planted with shrubs or hedges, upon which they seek shelter in times of danger; holes in rocks, or crevices in walls, are, in like manner, sometimes employed for this purpose. In their movements they are clumsy, and hop when upon the ground with apparent effort; their flight is violent, and far more rapid than accords with their strength, so that they are soon exhausted. Their song scarcely deserves the name, and the call-note is monotonous and unpleasing. These birds are intelligent and social in one sense of the word, but, although they love to congregate with other species, they are extremely quarrelsome and spiteful, especially during the season for choosing a mate, when most pertinacious and furious battles are of constant occurrence--the enraged combatants falling upon each other, biting, struggling, and screaming in a manner that is perfectly astounding to a spectator of this miniature warfare; indeed, it seems as if these encounters took place simply to gratify the pugnacious propensities of the irritable little creatures. All the members of this family bathe frequently, paddling about when in the water until their coats are quite saturated, and subsequently preen their feathers with the greatest care. Corn and insects form their principal food, their preference for the former, perhaps, accounting for the pertinacity with which they frequent the dwellings of men. During the summer they industriously pursue various kinds of insects, with which they feed their young. They are fond of fruit, and often attack our orchards, doing an incalculable amount of injury. It is believed that these birds produce many broods in the year. The nest, which is placed in a hole or upon the branch of a tree, consists only of a heap of scraps, thrown inartistically together without arrangement or care, except that the softest materials should line the interior.

Sparrows are totally unfitted for life in a cage.

THE COMMON SPARROW.

The COMMON or HOUSE SPARROW (_Passer domesticus_) is well known to all our readers. The mantle of the male bird is brown, striped with black, the top of the head blueish grey, edged at its sides with deep chestnut. The wings are marked with two bands, one white, the other of a rusty yellow colour, and extremely narrow; the cheeks are greyish white, the front of the neck black, and the under part of the body light grey. The female is of a light brownish grey upon the head, whilst over the eyes runs a pale yellow line; the back is light brown, streaked with black; the whole of the lower part of the body greyish white; the young resemble the mother until the first moulting season. The beak is black in summer and grey in winter, the feet horn-grey, and the eyes brown. Many varieties of plumage occasionally occur, some individuals being white, or yellowish white, and some nearly black. The male and female differ but little in size; both are about six or six and a quarter inches long, and nine to nine and a half across the wings.

The House Sparrows inhabit a greater extent of country than almost any other bird, being found over the whole of the northern portion of the Eastern hemisphere; moreover, it is a remarkable fact that wherever met with they are always in a state of semi-domestication: even in Australia, into which country Sparrows were only introduced some few years ago, they hold the same relation to man as in Europe. Few villages are to be found in which these little creatures have not settled, and that in the fullest sense of the word, as they never fly more than a mile from the place where they were born, except when in search of a spot on which to establish themselves. We are told by a Norwegian naturalist that these birds are yearly seen flying about some parts of Norway in couples, going from house to house, but that, not finding the country to their liking, they soon disappear, leaving no trace behind. Our House Sparrow is social in its habits, and even during the breeding season can hardly be said to live apart from its fellows; the nests are placed very close together, the males appearing to enjoy each other's society even whilst the process of incubation is going on. The young join the rest of the troop as soon as they can fly. During the whole time that corn can be obtained, or any green plants remain, these flocks fly daily over the neighbouring fields and plains in search of food, returning in the middle of the day to the villages, where they rest, and in the evening assemble upon the trees or roofs to make their preparations for passing the night--a proceeding that is always accompanied by great confusion and much squabbling. In the winter time these intelligent little creatures prepare beds or nests of the warmest description, into which they creep for shelter from the cold; they also frequent chimneys, quite regardless of the smoke and soot with which they are often covered.

The Sparrow will attach itself to man, but never sufficiently so to overlook the precautions necessary for its safety; it is ever upon its guard, and when angry even its inflated plumage cannot conceal the glances of its bright and crafty little eye; the unexpected opening of a window, the approach of a stranger, or even a stick held up like a gun, will at once excite alarm and cause its instant flight. Unlike the Pigeon race, this bird seems to become more wary and cunning as its intimacy with man increases--indeed, it never seems to forget the lessons taught by experience. Despite the clumsiness of its shape, the Sparrow has an air indicative of considerable spirit, as it hops energetically over the ground with tail borne aloft and head erect. The social disposition of these birds in no way interferes with their natural inclination to pick a quarrel upon every opportunity, and the most ludicrous combats often take place between the males relative to the appropriation of a mate. On these occasions, when the battle rages furiously, males and females alike mingle in the strife, until both parties come pecking, tumbling, and screaming through the air, to conclude the fight upon some neighbouring roof, forgetful in their fury of the safety they usually prize so highly, and take such precautions to ensure. During these contests they carry the head and neck erect, the tail raised, and their wings somewhat drooping. The Sparrow seldom flies at any great height; if perched upon a steeple, or other similar elevation, it will drop rapidly towards the ground before commencing its flight, rising again in a direct line when it wishes to attain the same altitude as before, although this attempt at soaring appears to cost the bird a great effort; it prefers, however, living at some distance from the ground.

These birds are capable of enduring almost any degree of cold, and but few perish even during the most severe winters. The note of the Sparrow is extremely unpleasing; the young utter the same cry as the parents, and are very noisy while being fed. The female is exceedingly prolific, breeding sometimes thrice during the year. The nest, which is built early in the spring, is little more than a rude heap of straw, sticks, and paper, lined with feathers, and furnished with a kind of lid. Even this slight preparation for her brood is often avoided by the cunning female, who will creep into the nest of a Swallow, there to deposit her eggs; and should she find a brood still occupying it, will at once destroy the helpless young ones, throwing them over the side, to make room for her own offspring, quite regardless of the cries of the unhappy mother. It was once believed that the Swallow would avenge the injury thus inflicted, but this we regard as a fable. The first eggs--generally from five to seven in number--are laid in March; the shell is smooth and delicate, of a dull purplish white, very variously spotted with brown or dark grey. The parents sit by turns on the nest for about thirteen or fourteen days; they feed the young at first with soft insects, and afterwards with corn that has been softened in their crops, until the fledglings are strong enough to eat seeds and various kinds of fruit. A week after the first brood has left the nest preparations are commenced for another, the second batch of eggs being laid within a fortnight of the departure of the first family; and thus they go on producing brood after brood until the end of September. Both parents are much attached to their offspring, and should one of them die, the other will use every effort to supply the wants of the young birds. Selby gives us a remarkable example of their perseverance in this duty. He had observed that a pair of Sparrows continued to carry food until winter was close at hand, and being anxious to discover the reason of such an unusual occurrence, examined the nest, in which he found a young bird whose foot had become entangled, and was in this manner imprisoned, so that the parents, unable to release it, continued to minister to its wants.

Many persons are inclined to regard Sparrows as mischievous creatures, without considering the immense services they render by devouring innumerable noxious insects. Frederick the Great of Prussia, we are told, was so prejudiced against these birds that he issued a decree that they should be shot whenever they appeared, and set a price upon their heads. The poor Sparrows were immediately pursued in all directions, and some thousands of dollars expended in the course of a few days by the State as payment for their destruction. The natural result of this barbarism followed; the trees that had been supposed to be injured by the birds were so covered with caterpillars and other insects, as to be not only barren of fruit, but also quite denuded of their leaves, so that the King was at once obliged to recall his decree, and had to command that Sparrows should be brought from all parts in order to repair the mischief that he had done. These birds have been introduced into Australia in the hope of their being similarly useful. Their flesh is often eaten, and in Italy small towers are built, in the compartments of which they make their nests; from these the young are taken as soon as fledged, and are considered great dainties when spitted on a stick and roasted. In old Gesner's time they were applied to a very different purpose: two spoonfuls of burnt Sparrow was supposed to be a cure for avarice, and the flesh of the nestlings, when applied with a little vinegar, was considered an excellent remedy for toothache. According to Pliny, their brains were extensively employed in medicine.

It is now satisfactorily decided that the Sparrows inhabiting Southern Europe are to be regarded as varieties of our _Passer domesticus_, and that the differences in their plumage are simply attributable to the diversity of external circumstances. The colours of the male alter considerably as it advances in age, or under any great change of climate; the reddish brown upon the head spreading towards the nape, while, on the contrary, the same beautiful tint upon the back becomes much more indistinct as the black shade at the lower part of the feathers extends and mingles with it. Thus the Sparrows of Provence and Italy, when no longer young, resemble ours in the colour of the back; but the head is generally entirely reddish brown or grey, the feathers being tipped with light brown only after the moulting season. These birds are very numerous in the warmer parts of Siberia, Buchara, Syria, Java, Egypt, and Nubia, and are also found in the islands of the Mediterranean, especially in Sardinia. The so-called Italian Sparrow (_Passer Italicus_) has been considered by some as constituting a distinct species. In the old males the top of the head and back of the neck are dark reddish brown, the sides of the neck and cheeks white, the gorge, throat, and upper part of the breast deep brownish black, and the sides reddish grey. The female is of a rusty white, mingled with grey on the under part of the body, and the markings above the eyes are much paler than in the Sparrow of Northern Europe. This bird is principally found in the South of France and Italy, but is quite unknown in the interior of Spain and Egypt. The _Passer Italiae_ will often mate with our common House Sparrow--the plumage of the progeny being a curious mixture of that of both parents.

THE SPANISH SPARROW.

The SPANISH SPARROW (_Passer Hispanicus_), or MARSH SPARROW (_Passer salicicolus_), is about six inches long, and its breadth across the span of its wings about nine inches and a half. The female is somewhat smaller than her mate, and in both birds the tail is generally longer and the tarsus shorter than in the Common Sparrow. In the colour of its plumage, however, the _Passer Hispanicus_ bears but little resemblance to the House Sparrow; in the old males the head and back of the neck are of a dark reddish brown, the back is black, marked with chestnut, and the throat, breast, and sides are almost black, with a pure white streak passing above the eyes. The rest of the plumage is similar to that of the House Sparrow, and the females of both species are almost identical in appearance.
