The Natural History of Cage Birds. Bechstein Johann Matthäus
tame animals are much more subject to disease than wild ones; and birds so much the more, as they are often shut up in very small cages, where they can take no exercise. It is often supposed that birds, in their natural free state, have no diseases; but people who will take the trouble to observe, will soon perceive the falsehood of this assertion. I have often found hedge-sparrows full of pimples, particularly in the naked parts, the feet, and round the beak. Their diseases are often increased by the delicacies of all kinds which are given them, such as biscuits and sugar, which injure the stomach, and cause a slow decay.
The principal diseases and their cures, according to my experience, are as follows; not, however, that different birds do not require, according to their food, different treatment.
I shall mention, under each bird, what must be done to cure those diseases which are peculiar to it, when general remedies fail.
This is a catarrh, or cold, by which the nostrils are stopped up, and the membrane covering the tongue is hardened by inflammation. In large birds it is common to remove this skin, taking it off from the base to the tip: by this means this part can again perspire, the saliva necessary for digestion can flow, and the taste and appetite returns. A mixture of fresh butter, pepper, and garlic, generally cures this catarrh. It is a good thing, also, for the birds to drink the pectoral infusion of speedwell; and the nostrils may be opened by passing up a small feather. The ruffling of the head, the beak often open and yellow at its base, and the tongue dry, are the most decisive indications of this disease.
The symptoms of this disease are frequent sneezing and shaking of the head. Some drops of pectoral elixir in the infusion of speedwell, which the sick birds must be made to take, appears to me to be the most efficacious remedy. I have given fowls even twenty drops of the elixir in a glass of the infusion.
When it is merely hoarseness, Dr. Handel, of Mayence, gave to his birds for several days, as their only drink, a very diluted decoction of dry figs, sweetened with a little sugar, and afterwards purged them for two days following, with the juice of carrots.
This is a very common disease among house birds. Those attacked with it have their breath short, often open their beaks as if to gasp for more air, and, when agitated or frightened, keep them open for a long time.
The cause of this disease may doubtless be found in the mode of life which these birds lead. Their food is generally too dry and heating, being principally hemp-seed, which is very injurious, but liked by all; and is the more hurtful, as it inclines them to eat too much. If to this be added the unchanged air of the rooms, particularly those which have stoves instead of chimneys, and the great heat which is kept up during winter, it is plain that there is much to injure the delicate lungs of these birds.
A moist and refreshing regimen and some aperients, more or less often, according to the violence of the disease, appears the most appropriate remedy. A favourite linnet and goldfinch, when attacked with very bad asthma, were relieved and preserved for several years by the following method.
The first thing was to leave off hemp-seed entirely, confining them solely to rape-seed; but giving them at the same time abundance of bread, soaked in pure water, and then pressed; lettuce, endive, or water-cresses, according to the seasons, twice a week, giving them boiled bread and milk, about the size of a nutmeg. This is made by throwing a piece of the crumb of white bread, about the size of a nut, into a teacupful of milk, boiling it, and stirring it all the time with a wooden spoon till it is of the consistency of pap. It must be quite cold before it is given to the birds, and must always be made fresh, for if sour it will prove injurious.
This paste, which they are very fond of, purges them sufficiently, and sensibly relieves them. In very violent attacks, nothing but this paste ought to be given for two or three days following, and this will soon give the desired relief.
When the disease is slight, or only begun, it is sufficient to give the bread and milk once in three or four days. When employed under similar circumstances, this treatment has cured several very valuable birds. It may not be useless here to renew the advice of always giving the birds an opportunity of bathing every day, by putting in their way a saucer, or any other small shallow bath, filled with water, which should never be too cold, and in winter always milk-warm.
One thing which is very injurious to the lungs of birds, and which too often occurs, is the fright occasioned by tormenting them, or by seizing them too suddenly; for the poor little things often rupture a blood-vessel in the breast while beating themselves about: a drop of blood in the beak is the sign, and a speedy death is the general consequence. If this do not happen, the breathing is not the less difficult and painful; and recovery is rare, at least without the greatest care and attention.
Birds which eat insects and worms, occasionally, by accident, swallow some extraneous substance, which, sticking in their throat, stops their respiration, and stifles them. The only remedy is to extract the foreign body, which requires much skill and dexterity.
When asthma is brought on by eating seeds which are too old, spoiled, or rancid, Dr. Handel recommends some drops of oxymel to be swallowed for eight days following. But the best way is to change the seed, and be sure there is none but good seed in the trough.
This is caused by giving unnatural food to the bird, which destroys the digestive power of its stomach. In this case it disgorges, ruffles its feathers, and does not arrange them, and becomes thin very fast. The best thing is to make it swallow a common spider, which purges it, and put a rusty nail into its water, which strengthens the intestines, giving it at the same time its proper and natural food. Green food, such as lettuce, endive, chickweed, and particularly water-cresses, is the safest remedy. A very great appetite is a sign of this disease. A siskin, that was dying of atrophy, had nothing but water-cresses for three days following, and on the fourth he sung.
This disorder may be known by the extreme thinness of the breast, the swelling of the lower part of the belly, the total loss of appetite, and similar symptoms. As a cure, Dr. Handel recommends the juice of the white turnip to be given to drink instead of water.
This disease may be discovered from the frequent unsuccessful endeavours of the bird to relieve itself. Aperients will be of use. If a spider does not produce the desired effect, anoint the vent of the bird with the head of a pin steeped in linseed oil; this sort of clyster generally succeeds; but if the disease attacks a bird which eats meal-worms, one of these, bruised in sweet oil and saffron, is the most certain remedy, and the bird will swallow it without the least hesitation. Boiled bread and milk is generally of great use.
This is a disease to which birds that have been caught recently are very subject, before they are accustomed to their new food. Most of these die of it: they continually void a white calcareous matter, which sticks to the feathers round the vent, and being very acrid causes inflammation in that part and in the intestines. Sometimes chalybeate water and the oil clyster produce good effects; but it is better, if possible, to procure for the bird its most natural food. Some people pull out the feathers from the tail and vent, and then rub these parts with fresh butter, but this is a very painful and cruel operation. They also mix the yolk of an egg boiled very hard with their food, but I have never found this succeed very well. If there be any hope of curing this disease it is by attacking it at the beginning, before inflammation is violent; boiled bread and milk, a great deal of lettuce, or any other similar green refreshing food, in general completely cures them.
In a case of chronic diarrhœa, which almost reduces the birds to skeletons, Dr. Handel prescribes chalybeate water mixed with a little milk for their drink, which, he says, is an easy and certain cure.
This is a disease with which some parrots are attacked. The best remedy is to make the birds drink a great deal of boiled milk, or even very fat broth; for their intestines, which are very much irritated, require something soothing to protect them from the acrid discharges, which, at the same time, must be corrected by healing food. Birds in this state generally do nothing but drink, therefore plenty of boiled milk should be given them, as it nourishes them, as well as acts medicinally, but should it appear to turn sour in the stomach it must, at least for some time, be discontinued.
