THE GOLDFINCH

Fringilla Carduelis, Linnæus; Le Chardonneret, Buffon; Der Distelfink, Bechstein

“Beauty of plumage,” says Buffon, “softness of voice, quickness of instinct, remarkable cleverness, proved docility, tender affection, are all united in this delightful little bird; and if it were rare, or if it came from a foreign country, it would then be valued as it deserves.” It is five inches and three quarters in length, of which the tail measures two. The beak, five lines long, very pointed, and rather flattish at the sides, is whitish, with the point horn-coloured. The shanks, six lines high, are delicate and brownish. The front of the head is a fine crimson, sometimes scarlet; a wide border of the same colour surrounds the under base of the beak; the bridle, as it is called, is black; the top of the head is black, which colour extends downwards, from the nape on each side, dividing the white on the cheeks from the white spot on the hinder part of the neck; the under part of the neck is white; the hinder part and the back are fine brown.

The female is rather smaller, and has not so much red round the bill; the bridle is brownish; the cheeks are mixed with light brown; the lesser wing coverts are brown; the back dark brown. The size, or the want of some white spots at the tips of the feathers, do not serve to distinguished the male from the female, as some bird-catchers say; nor ought we either to imagine that the size or number of these spots constitute different varieties; for all these distinctions are accidental, and depend on physical strength and age. Our bird-catchers think the large ones that are nearly the shape of the greater redpole form a distinct species, and they give them the name of Fir Goldfinches, because they say they always build in fir forests. Those that do not exceed the size of the red-breast, they call Orchard Goldfinches, because they suppose they always build in orchards. But these differences and pretences are imaginary, because both are found of different sizes, the orchard goldfinch large, and the fir, or wood goldfinch, quite small. The young ones that are hatched first are always stronger and larger than those hatched last, because they often carry off the food intended for the latter, and, therefore, being better fed, they become larger and stronger. This is sufficient to explain the difference of size in different individuals of the same species.

The following varieties are better established: – 1. The goldfinch, with a yellow breast; 2. With a white head; 3. With the head black – four young ones of this variety were found in the same nest; 4. The white goldfinch; 5. And the black goldfinch, this being either entirely black, which often happens in a cage, from giving it too much hemp seed, or from old age; or it only retains the yellow spot on the wings, which is also occasioned by captivity. M. Schilbach, superintendant of the menagerie of Cassel, tried an experiment on a whole brood. He deprived the birds of the light of the sun, even covered the cage with a piece of cloth, and, by these means, obtained very black goldfinches, with only the yellow spot on the wings; but they changed colour after moulting. Those in which the black does not change are very old. It is, in fact, a sign of approaching death.

Habitation. – In their wild state goldfinches are found in all parts of Europe, frequenting orchards, brambles, thickets, and mountainous districts, interspersed with wood and fields, during the summer. These birds are stationary, not changing their haunts in winter; they merely assemble in the autumn in families, or rather in little flocks of fifteen or twenty, seeking here and there places abounding in thistles, and only when the snow becomes too deep leaving such localities for others more accessible.

In the house, if kept in a cage, this should be a square one, because these birds do not like hopping about the upper part, as they would be forced to do, if in a bell-shaped cage, and also inclined to swing round. When they run on the floor they should be given a small artificial tree for a roost; for they like to perch on this whilst singing as well as sleeping.

Food. – Their food, when wild, consists of all kinds of small seeds, such as lettuce, goats'-beard, scorzonera, thistle, radish, and canary seed.

With us, in the house, they are principally fed on poppy, hemp seed, properly varied with lettuce, rape, and canary seed. If allowed to range, the second universal paste agrees very well with them. I have a goldfinch, which appears in good health, and eats not only of all the vegetables brought to table, but also meat, though, in their wild state, these birds never touch insects⁴⁶. They must have green food occasionally, such as chickweed, water-cresses, lettuce, or endive. These birds feed largely, when loose in the room, rarely leaving the food-dish, and driving off, if they can, with loud cries, any of their companions who wish to approach. They will allow those birds, however, to feed peaceably with them, that bear some analogy to their species, at least, in the nature of the stomach, such as the canary, siskin, and especially the lesser redpole, without distinction of male or female.

Breeding. – The goldfinch prefers building in large orchards, at the tops of trees, on weak and terminal branches. It makes the most beautiful nest of any of our birds, except the chaffinch, it being finely rounded, very elegant and firm. The outer part is constructed of fine moss, lichens, stalks of grass, and slender twigs; the whole being interwoven with the greatest nicety. The interior is lined with wool, horse-hair, and the cotton or down of the thistle⁴⁷, or willow. The female has rarely more than one brood in the year, unless she has been disturbed, and, in this case, the number of eggs is always diminished; on this account goldfinches never appear to increase in number. On a sea-green ground, the eggs have pale red spots and speckles, mingled with streaks of reddish black, which often form a circle at the large end. The parent birds disgorge the food into the young ones’ throats. Before the first moulting the heads of the young birds are grey. If it is only wished to take male birds from the nest, all that have a whitish ring round the root of the beak, must be left. They must be brought up on poppy-seed and the crumb of white bread, soaked in milk or water. Of all the natural songs of birds, they imitate most easily and perfectly that of the canary; they also pair with the canary, and produce together fruitful young ones. For this purpose, a male goldfinch is paired with one or two female canaries, which succeeds better than by placing a male canary with a female goldfinch; the former being more amorous, most favours this union, particularly if educated from youth. The fruit of this union are not less distinguished for the beauty of their plumage, often yellow, with the head, wings, and tail, of the goldfinch, than for the sweetness of their song, whether natural or acquired.

If you are afraid that a pair of canaries you value, may not hatch their eggs as you wish, place them in the nest of a goldfinch in your orchard, and you may be certain that they will be properly matured, and the young ones brought up in the best manner. When they are ready to fly, place them in a cage, and suspend it by the side of the nest till they can feed themselves. By this means you will have no trouble with their education.

Diseases. – Epilepsy is one of the commonest disorders of this bird. If the eyes are weak and swollen, anoint them with fresh butter. Stupor and giddiness being very properly attributed to too great a use of hemp seed, it is best to suppress it entirely, and supply its place with the seed of lettuce and thistles. This latter is so beneficial, that it would be well to give them, from time to time, a head to pluck the seeds for themselves.

Old age makes them blind, and deprives them of their beautiful colours; yet, notwithstanding all the evils with which they are afflicted, in a cage a goldfinch has been known to live sixteen years, and even twenty, or twenty-four years.

Mode of Taking. – In spring these birds are taken on a lure bush, with a decoy bird of their own species. They will also enter the area, or barn-floor trap, with chaffinches, if bundles of thistles are placed there; but it is not without difficulty, for they are very watchful to avoid nets and lime-twigs. In the winter, by building up bundles of thistles, and placing snares and traps on them, several may be caught; but in autumn and spring lime-twigs should be placed on them in preference. It is a still better plan to place bundles of thistles in a tree stuck about with lime-twigs. The goldfinch’s call is “tziflit,” or “sticlit,” which is its name in Bohemia.

Attractive Qualities. – The goldfinch is a very beautiful, lively, active bird, always in motion, and turning continually to the right and left. Its agreeable song, which is only discontinued during moulting, is a mixture of tones and harmonies, more or less dwelt upon, and the oftener the sound “fink” is introduced the more it is admired amongst us. There are some goldfinches that utter it only once or twice in their strains, whilst others will repeat it four or five times following. This species learn with difficulty to repeat airs from the flageolet, or other birds’ songs, and in this respect is inferior to canaries and linnets; but it is remarkable for its docility. Goldfinches have been seen to let off a small cannon, and imitate death. When properly instructed they will draw up their food and water. They are taught this by means of a chain or pulley, furnished with a soft leather band, two lines wide, pierced with four holes, through which the wings and feet are to be passed; the two ends meeting under the belly, and are retained there by a ring, to which is fastened the chain that supports the bucket containing the water or food. Whenever the little waterman wants either, he draws up the chain with his beak, fixing it at intervals with his foot, and thus succeeds in obtaining what he wishes; but if his little buckets are suspended to a pulley, raising one makes the other descend, and he can only enjoy his food and water in turn.

I have also seen goldfinches and siskins, placed in different cages, that have little bells fixed to the seed drawer in such a way that the bird cannot take its food without ringing them; the bells being harmonised, tolerably agreeable chimes are produced, but one is soon tired of such trifles.

The goldfinch is taught to go and come at command, without any danger of losing it, much sooner than the linnet, though the latter learns quite as soon to build in the room. To accomplish this feat the winter should be chosen, and the cage, containing a goldfinch that has not been rendered tender by having been too long accustomed to the heat of the room, must be placed on the outside of the window every day, or on a shelf intended for it, and where the mice cannot reach it. Hemp seed must be scattered round, and a bunch of thistle heads fastened by the side, the seeds of which should be mixed with the hemp seed. Presently one or more goldfinches, attracted by the call of the prisoner, collect, to take advantage of the scattered food; as soon as you have succeeded so far it is useless to let the decoy remain any longer exposed to the cold, which may injure it. It will be quite sufficient to place the cage within the window, and to put on the outside a cage as a trap, not for the sake of catching these birds, but to scare away the sparrows, that would soon eat up all the seed unless thus prevented; and in order that the trap may only close when you wish, the door should be supported by a string, passing into the room, and loosened, to catch the sparrows, but the goldfinches should be allowed to go in and out at pleasure, till the snow is on the point of disappearing, then close the trap on those you wish to keep: the birds thus captured should be placed in a cage, where they will soon grow tame, and learn to go and return to it. Whatever form this cage is of, the door should be hung so as to remain open as long as is required, and be closed without noise or alarming the bird, either by means of a spring, that may be acted on by the bird, without his perceiving it, or by his pushing the door of it open on the inside. When a goldfinch has been thus trained it may be let fly without fear the following August, at the time of moulting. It is true that it will be lost for some time, but it will not fail to return in December, when the ground is covered with snow, and it will sing much more sweetly than it would had it been kept prisoner. As soon as it has flown, a cage should constantly be hung outside the window, and seeds placed in it, that, if it should chance to return, it may find food; but it is rarely seen again till winter: at that time the cage should be so arranged that the door may be closed as soon as the bird enters, as it used to do in the room; the surest way is to attract it by a call bird. It must not be allowed to come out so often as before, and it will remain, without injury, shut up till the season arrives for giving it its liberty again. The same course may be pursued for the tit, and with still more success for the chaffinch, which does not enter the snares of the bird-catcher as easily as the others. If it is feared that it may be caught in a neighbouring area or barn-floor trap, it may be frightened from this snare in future, by stretching a net once, in the orchard or garden near. The greenfinch is the best for this manœuvre, as it is extremely fond of hemp seed, is more rarely taken, and returns less wild than the chaffinch. The birds that enjoy their liberty in the summer sing more finely than without this advantage, and, what is almost incredible, though taken to a distance of several leagues, they have always found their master’s house again⁴⁸.

THE SISKIN

Fringilla Spinus, Linnæus; Le Tarin, Buffon; Der Zeisig, Bechstein

This bird is four inches and three quarters in length, of which the tail measures one and three quarters. The beak, four lines long, becomes narrower towards the tip, which is very sharp and brown; the rest is light grey, and in winter white. The shanks, eight lines in height, are dusky; the top of the head and throat are black; the cheeks, the back of the neck, and back are green; the latter streaked with a dusky colour; the rump, breast, under part of the neck, and the line that passes over the eyes, are greenish yellow.

The throat of the male rarely becomes black till the second year; the older it becomes the more of yellow and beauty it attains.

The varieties are the black siskin, the white siskin, and the speckled siskin. I have occasionally killed these birds with a breast entirely black.

Habitation. – In its wild state it is found throughout Europe; it is very common in Germany, where it remains all the year⁴⁹, but in winter it wanders about in search of food, and most frequents the parts well planted with alders. In the house, whether in a cage or not, it soon becomes very familiar.

Food. – When wild it varies according to the season; in summer it eats in the woods the seeds of the pine and fir; in autumn, of hops, thistles, burdock; in winter, of the alder and the buds of trees.

In the house its food is poppy-seed and a little hemp-seed bruised. If allowed to range, the first universal paste suits it. It is a complete glutton, and, though so small, eats more than the chaffinch; it is at the seed drawer from morning till night, constantly eating, and driving off all its companions. It does not drink less, and requires abundance of fresh water; yet it bathes but little, only plunging the beak in the water, and thus scattering it over its feathers, but it is very assiduous in arranging them; it may be called a fop, always engaged with finery.

Breeding. – The siskin rarely builds its nest among the alders, but generally in the pine forests, placing it at the extremity of the highest branches, and fixing it there with cobwebs, the threads of insects and lichens. The outer part is well formed of small twigs, and the lining is formed of finely divided roots. It has two broods in the year, each of five or six eggs, of a light grey, strongly spotted with purplish brown, particularly at the large end. The young males become finer each year till the fourth.

The mules, produced by the siskin pairing with the canary, partake of the two species, and are very prettily spotted if the canary is yellow; but this union is not so easy as that with the green canary, which appears to bear a nearer relation to the siskin.

Diseases. – To the other maladies common to the birds of this family we must add epilepsy, of which these birds often die⁵⁰. They may, however, be kept from eight to twelve years.

Mode of Taking. – With good traps and nets made for this purpose, several dozen of these birds may be taken at once in the winter. They also collect in numbers, in the spring, on the decoy bush, and they are so fearless, that in the villages a person, who has his house situated near a stream bordered with alders, need only place a siskin in the window, near a stick covered with bird-lime, and he may catch as many as he wishes. I have caught some at my window in a cage strewed with hemp and poppy-seed, by letting the door fall by means of a string, when the birds had entered, one of the decoy birds in my room serving to attract them. When the place where they drink at noon is discovered amongst the alders, numbers may be caught by merely laying across the stream some branches covered with bird-lime.

Attractive Qualities. – Their plumage and song are both attractive, though with the latter several tones are mingled, that somewhat resemble the noise made by a stocking-loom. This makes them great favourites with stocking-weavers. They imitate tolerably the song of other birds, such as that of the tit, the chaffinch, and the lark; but they cannot give a musical air. Their carolling is only interrupted during moulting, and very much tends to excite their companions to warble in their turn. The loss of their liberty affects them so little, that they will eat as soon as let out of the hand, after being caught, and on the second day will allow any one to approach their cage without alarm. They are soon taught to draw up little buckets, and many other little manœuvres that they execute gaily; there is no difficulty in accustoming them to go and return if the winter is chosen; the cage should be kept open at the window, and hemp and poppy-seed scattered at the entrance; they will return there in general, and bring several companions with them. This plan will not succeed so well in March, September, and October, the time when these birds roam through the country in search of food, though I have seen some tamed in this manner return after a long absence.

THE RING SPARROW

Fringilla petronia, Linnæus; La Soulci, Buffon; Der Graufink, Bechstein

Independently of the beak, this bird may be taken for a female yellowhammer, as it resembles it so much in its shape and plumage. Its length is five inches three-quarters, of which the tail measures two. The beak, five lines long, is thick at the base, grey brown above, and white below. The feet, ten lines high, are grey brown; the whole head is of a reddish ash-colour, but a dirty white ring surrounds it from one eye to the other.

The female is greyer on the upper part of the body, and the front of the neck is only pale yellow.

Observations. – Ring sparrows are found in most European forests, or woods; they are common enough in several parts of Germany⁵¹, those that inhabit the northern parts removing in winter; but the others are stationary.

They live on seeds and insects like the house sparrow, and make their nests in hollows of trees. In the house they are fed on rape and poppy-seeds; they also readily eat the first universal paste. They are less prized for their warbling, which is insignificant, than for their beauty or rarity.
