The Natural History of Cage Birds. Bechstein Johann Matthäus
is most prized and admired in house birds is undoubtedly their song. This may be natural or artificial, the former being as varied as the species of the birds, for I know of no two indigenous species quite similar in their song; I ought, perhaps, to except the three species of shrike I have given, which, from their surprising memory, can imitate the songs of other birds so as to be mistaken for them: but a naturalist would soon perceive a slight mixture of the song natural to the imitator, and thus easily distinguish between the shrike that copied, and the titlark or red-breast copied from1. It is so much the more important to be well versed in the different birds’ songs, as to this knowledge alone we are indebted for several curious observations on these pretty creatures.
An artificial song is one borrowed from a bird that the young ones have heard singing in the room, a person’s whistling, a flageolet, or a bird-organ. Nearly all birds, when young, will learn some strains of airs whistled or played to them regularly every day; but it is only those whose memory is capable of retaining these that will abandon their natural song, and adopt fluently, and repeat without hesitation, the air that has been taught them. Thus, a young goldfinch learns, it is true, some part of the melody played to a bullfinch, but it will never be able to render it as perfectly as this bird; a difference not caused by the greater or less suppleness of the organ, but rather by the superiority of memory in the one species over that of the other.
We distinguish in birds a chirping and warbling, or song, properly so called; besides this, several species, with a large, fleshy, undivided tongue, are able to repeat articulate sounds, and they are then said to talk, such as parrots and jays.
It is remarkable, that birds which do not sing all the year, such as the red-breast, siskin, and goldfinch, seem obliged, after moulting, to learn to warble, as though they had forgotten; but I have seen enough to convince me that these attempts are merely to render the larynx pliant, and are a kind of chirping, the notes of which have but little relation to the proper song; for a slight attention will discover that the larynx becomes gradually capable of giving the common warble.
This method of recovering the song does not then show deficiency of memory, but rigidity occasioned by the disuse of the larynx. The chaffinch will exercise itself in this way some weeks before it attains its former proficiency, and the nightingale practises as long the strains of his beautiful song, before he gives it full, clear, and in all its extent2.
The strength and compass of a bird’s voice depend on the size and proportionate force of the larynx. In the female it is weak and small, and this accounts for her want of song. None of our woodland songsters produces more striking, vigorous, and prolonged sounds than the nightingale; and none is known with so ample and strong a larynx: but as we are able to improve the organisation of the body by exercise and habit, so may we strengthen and extend the larynx of several birds of the same species, so as to amplify the song in consequence, by more nutritive food, proper care, sounds that excite emulation, and the like; chaffinches, bullfinches, canaries, and other birds reared in the house, furnish daily examples of this.
I should not omit mentioning here an observation of Mr. Daines Barington3, which tends to prove the possibility of improving the song of wild birds, by rearing linnets, sparrows, and others, near some good warbler, such as a nightingale or canary, and then setting them at liberty; but, though there is some truth in this assertion, yet it is subject to certain restrictions. I only know of two ways of carrying this idea into execution; one by suspending the cages of the best warblers in the orchard where the birds which they are to teach breed; the other, to enclose these warblers in a large aviary of iron wire, in the open air. There let them teach their young ones, which may be set at liberty as soon as they are able to fly: but birds taken very young from the nest, and reared, formed, and educated in the house, would not have instinct to find their food when set at liberty, and must perish of hunger, or at least die in the winter.
The same remarks are applicable to a work published by M. Gambory at Copenhagen, in the year 1800.
I think, indeed, it is better to be contented with possessing in our houses artificial songs than to take so much trouble to alter and spoil the very delightful music of nature4.
HABITATIONS OF TAME BIRDS
The space assigned to tame birds varies according to their nature and destination. All are less at ease in a cage than when at liberty in a room, where young pine branches, cut in winter or early in spring, should be placed for their accommodation5. Several, however, never sing unless confined within narrow limits, being obliged, as it would appear, to solace themselves, for the want of liberty, with their song; consequently, birds only prized for the beauty of their plumage or their pleasing actions, are best placed in a room. Rather large birds, such as thrushes, should have a room appropriated to them, or be kept in a large aviary, as they give a very unpleasant smell to the place which they occupy, unless carefully cleaned; but their young ones may be allowed the range of any apartment, placing in a corner a cage or branch to rest and sleep on, where they may run and hop freely, seeking a roosting-place for themselves in the evening, on the fir branches placed for that purpose; or in a cage with several divisions, into which they soon learn to retire. Some birds, such as the dunnock and the blue-breast, sing best in this state of liberty. It is necessary to avoid placing them with shrikes or tits, as these often, in the midst of plenty of food, will kill smaller birds, for the sake of eating the brain or intestines. Those that are confined that we may better enjoy the beauty of their song, should have a cage proportioned to their natural vivacity: a lark, for example, requires a larger cage than a chaffinch. The habits of the birds must also be considered, whether they rest on the ground or perch on sticks. Thus, the nightingale must have perches, while the sky-lark never makes use of these.
In the account of each bird I shall point out what shaped cage I have found most suitable.
In every case cleanliness is absolutely necessary, in order to keep birds a long time, as well as healthy and active. In general it is better not to disturb the birds very often; but if not every day, yet every week at furthest, it is necessary to clean even the perches of those that roost, and strew sand where they keep at the bottom. Negligence in this entails many inconveniences, – unpleasant smells from sick birds, gouty feet to some birds, loss of the use of their limbs or all their claws; such sad experience may at length cure the negligent amateur. “We love birds,” they say; “No,” I reply, “you love yourselves, not them, if you neglect to keep them clean.”
In washing the feet of birds they must first be soaked in warm water, or the dirt will be so pasted on the skin that in removing it the bird will be wounded, and the irritation thus excited may soon occasion dangerous ulcers. House birds are generally subject to sore feet, and great attention is therefore necessary to examine them often if they are not attacked; a hair wound round them will sometimes become drawn so tight that in time the part will shrivel up and drop off. Another proof of the necessity of care in cleaning is, that few birds preserve their claws after having been kept some years in the house. It must be confessed, however, that among birds of the same species there is a very marked difference in this respect, some being always extremely clean, whilst others are for ever dirty, and seldom clean themselves. There are also some species in which cleanliness seems an innate quality; among these are yellow hammers, reed buntings, and linnets; the latter especially have always appeared to me patterns of neatness, and though I have had many, I do not recollect being obliged to clean the feet of any, whilst larks and fauvettes have them always dirty, and let them fester with ulcers rather than take the trouble to clean them6.
Many amateurs amuse themselves with taming their birds so completely that they can let them fly out of a window and recall them at pleasure. A friend of mine, who tamed not only birds, but also adders, otters, weasels, foxes, and the like, knew how to render them so familiar that at the least sign they would follow him anywhere. This method was as easy as it was sure, and I can judge of it from having been an eye-witness to the effect; it is as follows:

Besides, we cannot say that there is a want of variety in this music. I may again quote Mr. Barington (Phil. Trans.): “The death of the male parent, just at the time his instructions were required, will occasion some variety in the song of the young ones, who will thus have their attention directed to other birds, which they will imitate or modify according to the conformation of their larynx; and they will thus create new variations, which will afterwards be imitated by their young ones, and become hereditary, until a circumstance of a similar nature may introduce greater variations. If care was taken there need not be two birds that sung exactly alike: however, these varieties are confined within certain limits.” – Translator.

If pine and fir branches cannot be obtained, oak, elm, or beech will do, cut in winter; though not green, yet there will be leaves. – Translator.

This perhaps depends on the peculiar forms of the bills more than on inclination, for the fauvette and blackcap often attempt to clean their feet without success. – Translator.
