AUTHOR’S PREFACE

The Natural History of Cage Birds, which I now lay before the public, is a work I have long been solicited to write. There are many people who like to keep birds, who neither know their habits nor the proper treatment or food requisite for them. Even those who are not altogether ignorant of these, often have but very limited, superficial, and, what is worse, sometimes erroneous ideas on the subject. It is for such readers I have given the following Introduction; for professed naturalists will find nothing there but what they have already learnt, either from my own works or from those of other authors on natural history.

If long experience and minute observation on the subject of his work is calculated to gain an author credit, I flatter myself that this will not be denied me, since from my earliest youth I have delighted in being surrounded with birds, and am so accustomed to them that I cannot write at my desk with pleasure, or even with attention, unless animated by the warbling of the pleasing little creatures which enliven my room. My passion is carried so far, that I always have about thirty birds around me, and this has naturally led me to consider the best and easiest mode of procuring them, as well as of feeding and preserving them in health. Few amateurs, therefore, are better fitted than myself to write on this subject; and I hope I have done it to the satisfaction of the public. I ought also to notice in this place the plan of my work, as my book may fall into the hands both of those who might feel a wish to learn more particulars, and of those who may think much less would have sufficed.

I have described all the indigenous European birds with which I am acquainted that are capable of being tamed, and are pleasing in the house. As to foreign ones, I have only spoken of those I have occasionally seen in Germany, and which can be procured without much difficulty.

I have followed the same plan in their natural history which I have pursued in my other works on birds.

Description. – Under this head I have entered into particular details, in order that the amateur may the better satisfy himself in discriminating the species and the sex of the bird before him. This knowledge is exceedingly necessary, as the bird-dealers are not very scrupulous in deceiving their customers, either by selling one species for another, or a female for a male. These descriptions may likewise have the advantage of inspiring a taste for ornithology in the bosom of a mere amateur, who may, by repeated observations, afterwards enrich this branch of natural history with his own remarks.

Habitation. – On forming a wish to possess any particular bird, it is natural to try to discover what situations it frequents in order to find it, and when it has been found and secured, a desire to know the best place to keep it in follows as a matter of course.

Food. – In keeping tame birds it is most important to know what food is best adapted to each species; that is to say, what approaches nearest to its natural aliment. I have therefore divided the directions on this point into two parts; showing in the first the natural food of the bird in its wild state, and in the second what is best for it in confinement.

Breeding. – Many birds succeed best when reared from the nest, which makes it necessary to speak of their manner of being hatched, and the like.

Diseases. – Birds being very tender creatures, on passing from a state of liberty to slavery, in which they lose the means of exercise and proper food, are soon afflicted with many diseases occasioned by this change alone, without reckoning others that naturally follow in their train. Under this head I endeavour to point out these, and their proper treatment; but I confess that this is the most imperfect part of my work, and I wish some clever experienced medical man would take the trouble to render it more correct.

Chase. – On going into the country a wish often arises to procure a bird, and therefore under this head I have described the method of catching such species as may be desired.

Attractive Qualities. – Under this head I have stated the properties which render a bird worthy of our notice, and of being tamed and kept in the house.

The volume ends with an alphabetical index, which will enable a person instantly to find the birds whose history he requires. May my work be as useful as it is my wish to make it, and my intentions will be accomplished.

SECOND EDITION

The call for a second edition is no inconsiderable proof to me that I accomplished my purpose in the first. None of my works have had a more flattering reception, from all classes of readers; but particularly from some of the most distinguished, who have given me repeated proofs of their satisfaction. I have also had the pleasure of assisting many amateurs with my experience, who have honoured me with questions. This pleasure is now increased by being able to render these instructions general, and to perfect this new edition by later observations, some communicated by others, which I judged it right to introduce. If any reader is surprised at not finding in this work many foreign birds seen in France, Holland, or in some of the maritime towns of Germany, it is because I have never had an opportunity of observing them myself: in a word, it is very pleasing to me to feel that my work has increased the number of the lovers of natural history; and I hope to see them still increasing. It is, indeed, my earnest wish that it may contribute more and more to the love of that class of attractive creatures with which the Creator has adorned the earth, and which sing His praises so melodiously and unceasingly!

THIRD EDITION

A new edition of my Natural History of Cage Birds having been called for, I have made many additions and improvements in the work, as will appear on comparison. Some have alleged that I have been too diffuse in my descriptions, and others find fault that I have introduced birds difficult to tame, such as the gold-crested wren and the common wren. In the latter case, at least, the most ample details are excusable, as the birds require more care; yet I know several amateurs who always have one or two wrens flying about a room, or in a cage, and to let loose so delicate a little bird as the gold-crested wren always gives great pleasure. Besides, the minutest detail can never, in such cases, do any harm. I have likewise added some foreign birds, several of which have been but recently introduced in this country by bird dealers.

NOTICE BY THE TRANSLATOR

The work of Dr. Bechstein upon Cage Birds has been so highly esteemed on the Continent that it has passed through several editions, both in the original and in translations. Besides rendering as faithfully as care could effect, the interesting details of the author, numerous notes have been added, as well as several species introduced, which have recently been kept with success in this country by the Hon. and Rev. Mr. Herbert, Mr. Sweet, Mr. Blyth, and others. The mode of management also peculiar to these, and so different in some points from that recommended by Dr. Bechstein, has been given in detail. It is to be hoped that this translation may have similar success, and produce similar effects in increasing the taste for Natural History, which the original has had on the Continent. It is proper to add, that the drawings of cages, which illustrate this edition, were selected by permission of Mr. Cato, Holborn Bridge, from the numerous elegant specimens which his stock contains.

London,

November 1837.

INTRODUCTION

By cage birds, I mean those kept by amateurs, for amusement, in their apartments, generally selected for sweetness of song or beauty of plumage; but the naturalist has other reasons for surrounding himself with these pleasing creatures: they enliven him, and he delights in studying their habits and characters. To attain these objects it is necessary, in the first place, to be able to distinguish readily between the males and females, since the former are generally superior in their powers of song, and therefore preferable. I have, for this reason, made a point, in the following sketch of the history of house birds, of showing the colours and other marks which characterise the two sexes; and, as all birds cannot be tamed, whilst many others offer no inducement to make the attempt, it follows that those about to be spoken of must necessarily be but a small proportion of all the known species of birds.

SONGS OF TAME BIRDS

What 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:

When he wishes to accustom a bird to fly out and return, or go out of doors perched on his hand or shoulder, he begins by opening the cage and teazing the bird with a feather. The bird soon pecks at it, then at the finger, and at last ventures outside the cage to fly on the finger presented to it. My friend then caresses it, and gives it something nice to eat, so that it soon becomes accustomed to feed on the hand. When this is attained, he begins to teach it to come at a certain call, and as soon as it will allow itself to be taken, he carries it on his hand or shoulder from room to room, the doors and windows being at first well closed; he also lets it fly about a little, making it return when called. At last, when the bird comes at his call, without hesitation or fear of men or animals, he tries it with precaution out of doors. It thus by degrees becomes so accustomed to him that he can take it into the garden, even in the midst of a large company, without any fear of its flying away.

Great precaution is necessary in spring, and during the pairing season, when taking out old birds that have been thus trained; for, upon hearing the call of their own species, they soon fly off to resume their wild state. Young linnets, bullfinches, and canaries, are the species with which this method succeeds best.

FOOD OF TAME BIRDS

It is very necessary to procure for house birds food which is like, or at least which nearly resembles, what they would procure for themselves in their wild state. This is rather difficult, and sometimes almost impossible, for where can we find in our climate the seeds on which the Indian birds feed in their own country? Our only resource then is to endeavour, with judgment, to accustom these birds to that food which necessity obliges us to give them. There are some birds, such as chaffinches, bullfinches, thrushes, and the Bohemian chatterer, which are so manageable in this respect, that as soon as they are brought into the house they eat without hesitation anything that is given to them; but others, which are more delicate, will absolutely eat nothing, either through disgust of their new food, or despair at the loss of their liberty; with these great precaution is necessary. Dr. Meyer, of Offenbach, writes to me on this subject as follows: “The following is the best method of accustoming newly-taken birds to their change of food, a thing which is often very difficult to accomplish with some species. After having put the bird in the cage it must be left quiet for some hours, without disturbing it at all; it must then be taken and plunged into fresh water, and immediately replaced in the cage. At first it will appear faint and exhausted, but it will soon recover, arrange its feathers, become quite lively, and will be sure to eat whatever is given to it. It is a well known fact that bathing gives an appetite to birds, for the same reason that it does to men.”

If, as an exception, one of these delicate birds, among which are most of the songsters, eats with eagerness as soon as it is brought into the house, it is a sign of death, for it seems like an indifference which is not natural, and which is always the consequence of disease. Those birds which retire into a corner, moping for some hours, are the most likely to live; it is only requisite to leave them alone, and by degrees they recover from their sullenness.

In order to give some general rules for the best food for house birds, I have divided them into four classes: —

The first comprehends those birds which live only on seeds, such as canaries, goldfinches, and siskins.

The second are those which feed on both seeds and insects, such as quails, larks, chaffinches, and bullfinches; some of these also eat berries and the buds of trees.

The third are those which seek only berries and insects, such as nightingales, red-breasts, thrushes, and fauvettes.

The fourth are those which eat insects only, such as wagtails, wheatears, stonechats, and blue-breasts.

The species in this last class are the most difficult to preserve; but most of them, having nothing particular in their song, offer no compensation for the trouble and care which they require; but the following is the best method for success. After having collected the flies, which in spring may often be seen in great numbers on the windows of old buildings, they must be dried, and preserved in a jar. When live insects can no longer be found, these flies must be mixed with the paste, hereafter described, which may be regarded as a general or universal food, and given to the most delicate birds, such as nightingales, provided ants’ eggs or meal worms are now and then mixed with it.

Recipe for the general food. – In proportion to the number of birds, white bread enough must be baked to last for three months. When it is well baked, and stale, it must be put again into the oven, and left there until cold. It is then fit to be pounded in a mortar, and will keep several months without becoming bad. Every day a teaspoonful for each bird is taken of this meal, on which is poured three times as much cold, or lukewarm, but not boiling, milk. If the meal be good, a firm paste will be formed, which must be chopped very small on a board. This paste, which is very nourishing, may be kept a long time without becoming sour or sticky; on the contrary, it is always dry and brittle. As soon as a delicate bird is brought in, some flies or chopped worms should be mixed with the paste, which will attract it to eat. It will soon be accustomed to this food, which will keep it in life and health.

Experience teaches me that a mixture of crushed canary, hemp, and rape-seed, is the favourite food of canaries; goldfinches and siskins prefer poppy-seed, and sometimes a little crushed hemp-seed; linnets and bullfinches like the rape-seed alone. It is better to soak it for the young chaffinches, bullfinches, and others; in order to do this, as much rape-seed as is wanted should be put into a jar, covered with water, and placed in a moderate heat, in winter near the fire, in summer in the sun. If this is done in the morning, after feeding the birds, the soaked seed will do for the next morning. All of them ought to have green food besides, as chickweed, cabbage leaves, lettuce, endive, and water-cresses. Sand should be put in the bottom of the cages, for it seems necessary for digestion7.

Amongst those of the second class, the quails like cheese and the crumbs of bread; the lark barley-meal, with cabbage, chopped cress, poppy-seed mixed with bread crumbs, and in winter, oats; the chaffinches, rape-seed, and sometimes in summer a little crushed hemp-seed. Too much hemp-seed, however, is hurtful to birds, and should only be given as a delicacy now and then, for when they eat too much of it they become asthmatic, blind, and generally die of consumption. Yellowhammers like the same food as the larks, without the vegetables; the tits like hemp-seed, pine-seed, bacon, meat, suet, bread, walnuts, almonds, and filberts.

The birds of the first class are easily preserved in the house, at least if not taken during the pairing season, for then the loss of their liberty affects them so much that they become sullen, and die of hunger.

Although the notice of a universal remedy is generally rather suspected, I cannot refrain from here recommending one or two sorts of paste which I have always used, and which agreed so well with all my birds, excepting those which I keep in cages on account of their beautiful songs, that it may justly be termed general or universal food: it is not only very simple and cheap, but also prevents great loss of time to those who possess a great many birds.

The universal paste. – To make the first paste, take a white loaf which is well baked and stale, put it into fresh water, and leave it there until quite soaked through, then squeeze out the water and pour boiled milk over the loaf8, adding about two thirds of barley-meal with the bran well sifted out, or, what is still better, wheat-meal; but, as this is dearer, it may be done without.

For the second paste, grate a carrot very nicely (this root may be kept a whole year if buried in sand), then soak a small white loaf in fresh water, press the water out, and put it and the grated carrot into an earthen pan, add two handfuls of barley or wheat meal, and mix the whole well together with a pestle.

These pastes should be made fresh every morning, as they soon become sour, particularly the first, and consequently hurtful. For this purpose I have a feeding-trough, round which there is room enough for half my birds. It is better to have it made of earthenware, stone, or delft ware, rather than wood, as being more easily cleaned, and not so likely to cause the food to become sour.

The first paste agrees so well with all my birds, which are not more than thirty or forty, at liberty in the room, that they are always healthy, and preserve their feathers, so that they have no appearance of being prisoners. Those which live only on seeds, or only on insects, eat this food with equal avidity; and chaffinches, linnets, goldfinches, siskins, canaries, fauvettes, red-breasts, all species of larks, quails, yellowhammers, buntings, blue-breasts, and redstarts may be seen eating out of the same dish.

Sometimes, as a delicacy, they may be given a little hemp, poppy, and rape-seed, crumbs of bread, and ants’ eggs. One of these is necessary for the birds of the third and fourth class.

Every morning fresh water must be given to the birds, both for drinking and bathing. When a great many are left at liberty, one dish will do for them all, about eight inches long and two in depth and width, divided into several partitions, by which means they are prevented from plunging entirely into the water, and in consequence making the place always dirty and damp9. A vessel of the same size and shape will do for holding the universal paste, but then it must have no partitions. Quails and larks require sand, which does for them instead of water for bathing.

Some birds swallow directly whatever is thrown to them: great care must be taken to avoid giving them anything with pepper on it, or bad meat. This must be a general rule. I shall also remark, that food sufficient for one day only must be given to birds kept in cages, for they are accustomed to scatter it about, picking out the best, and leaving only the worst for the next morning; this makes them pine, and puts, them out of humour.

Mr. Sweet’s food for soft-billed birds (sylviadæ). – The birds of this sort, though the finest songsters and most interesting of all the feathered tribe, have been less known or noticed than others, probably owing to the greater number only visiting us in summer, when the trees are so densely clothed with foliage that birds are not easily seen, and when heard sing are generally considered by those who hear them to be either blackbirds or thrushes, or some of the more common singing birds. When they are seen the greater number of them receive the general appellation of white-throat, without distinction, though this is rather singular, since they are all very distinct when examined, and their songs are all very different. If you speak to a bird-fancier or bird-catcher about any of them, you might as well talk of a bird in the wilds of America, for they know nothing of them. Many of them are therefore difficult to be procured in the neighbourhood of London, though most of them are plentiful there.

With care, the whole of them may be preserved in good health through the year, and many of them will sing through the greater part of the winter if properly managed. They require to be kept warm; the room in which they are should never be allowed to be below temperate, or they will suffer from it, particularly the tender sorts; at first the cold will make them lose their sight, after which they seldom recover. The redstart and nightingale are most subject to this; it sometimes also happens to the fauvette, and also to the whinchat.

When in a wild state, the birds of this sort feed principally on insects or fruit, and berries of various kinds. None of them are seed birds, so that they must be managed accordingly. The general food which I give them is hemp-seed, bruised up in boiling water, as small as it can be made; I then put to this about the same quantity, or rather more of bread, on which is also poured boiling water, and then the whole is bruised up together into a moist paste, particular care being required that there be very little or no salt in the bread; for should there be rather much it will kill the whole of the birds. The food should also be mixed up fresh every morning, as it soon spoils and turns sour, in which case the birds will not touch it, and sometimes it will make them go off their food altogether. When given to the birds, some fresh, raw, lean meat ought to be cut up small enough for them to swallow, and mixed with it I generally put about the same quantity of meat as paste, and sometimes they will peck out the meat and leave the paste; at other times they will eat the paste and leave the meat; but in general they eat it all up together, particularly where several different species are kept together in the same large cage, a plan which I consider by far the best, as they amuse each other, and keep one another warm in cold weather. Besides the above food, an egg should be boiled very hard, the yolk taken out and crumbled or cut in small pieces for them; the white they will not eat. One egg I consider enough for twenty birds for one day, with their other food, it being only intended as a change of diet, which they will not continue well in health without.

4.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.
5.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.
6.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.

8.The reason of this union of vegetable and animal food may be easily seen; the bread supplies the seed for the birds of the first class, and the milk the insects for those of the second, while the third and fourth here find their mixed food; and thus it ought to agree with all. Besides, the birds of the first class do not confine themselves exclusively to seeds; in their wild state they eat many insects, and some even feed their young entirely with them; this proves that animal food is sometimes useful and beneficial to them. – Translator.
