The bullfinch can also imitate the songs of other birds; but in general it is not permitted to do so, that it may only learn to repeat the airs which are taught it.
Different degrees of capacity are shown here, as well as in other animals. One young bullfinch learns with ease and quickness, another with difficulty and slowly; the former will repeat, without hesitation, several parts of a song; the latter will be hardly able to whistle one, after nine months' uninterrupted teaching. But it has been remarked that those birds which learn with most difficulty remember the songs, which have once been well learnt, better and longer, and rarely forget them, even when moulting. Mr. Thiem[33], bird-seller, at Waltershausen, near Gotha, sends annually to Berlin and London one or two hundred bullfinches, instructed in this manner, at from one to several pounds sterling a-piece, according as they are more or less accomplished, whilst a wild one would cost only two or three pence. These, however, are also kept in the room and prized, both on account of their beauty and the great ease with which they are tamed; they soon learn to fly on the hand, to receive their food, or will even take it from the mouth, and become at last as familiar as if they had been reared from the nest. The following are the means which are employed to tame them:—As soon as a bullfinch is caught and brought into the room, it must be put into a cage with food sufficient for the first day only; for the loss of its liberty does not prevent its eating as soon as it is disengaged from the lime twigs or noose. The next day a band must be put round the body and wings, like that which bird-catchers put round a decoy bird, which they let run about out of doors; by means of this band the bullfinch may be fastened by a piece of packthread, a foot in length, to some place from which it cannot fall; this will prevent its beating itself to death with its wings; a little bell may be fastened to a box, which when filled with food must be given to the bird, at the same time ringing the bell; it must be then left that it may eat; this must be repeated several times in the day; the same must be done when it is given anything to drink. The poor little captive will not at first either eat or drink in any one’s presence; it is therefore necessary to retire for the two first days after having given it the box, and only approach it by degrees, till it is accustomed to eat in the presence of its master, which it will soon be, for generally on the third day, as soon as it hears the bell and sees the box, it hops forward, and eats without the least shyness. Then the distance must be increased by degrees to make it come farther and farther, when, as soon as it has eaten, it may be taken on the hand and carried here and there, though it may seem a little frightened, but not being able to escape it will soon become used to this treatment, and will even begin to come to eat on the hand by continuing to do this for the third and fourth days; it will fly of itself at the sound of the bell to the hand which holds the box; after this the fastening may be loosened, and if one only move from the bird gradually, it will fearlessly approach and perch on the hand. Should it escape, however, it must be again confined and left without food for some hours. By this means a wild bullfinch will in eight days become accustomed to fly immediately to the hand, or wherever it hears the bell; in order to finish its education, it is well to increase the difficulty of getting at its food, by putting it in a small bag with a very little opening; it must also only have rape seed in the cage, keeping the hemp seed, which it likes best, for the hand or little bag. It may be taught to drink out of one’s mouth by keeping it without water for five or six hours. It may even be accustomed to go and return, provided the house is not too near a wood. The surest means of preventing too long an absence is to put a female bullfinch in a cage in the window, or to leave her in the room with her wing clipped; its affection will soon bring it back to her, and it will certainly never abandon her altogether.
Tame bullfinches have been known (says Buffon) to escape from the aviary, and live at liberty in the woods for a whole year, and then to recollect the voice of the person who had reared them, return to her, never more to leave her. Others have been known, which when forced to leave their first master, have died of grief. These birds remember very well, and often too well, any one who has injured them. One of them having been thrown down, with its cage, by some of the lowest order of people, did not seem at first much disturbed by it, but afterwards it would fall into convulsions as soon as it saw any shabbily dressed person, and it died in one of these fits eight months after the first accident.
A bullfinch, belonging to a lady often mentioned before, being subject to very frightful dreams, which made it fall from its perch, and beat itself in the cage, no sooner heard the affectionate voice of its mistress than, notwithstanding the darkness of the night, it became immediately tranquil, and re-ascended its perch to sleep again. It was very fond of chickweed, and as soon as it perceived one bringing it to him, however much care was taken to prevent its finding it easily, it would show its joy by its actions and cries.
THE GREEN BIRD.
Loxia chloris, Linnæus; Le Verdier, Buffon; Der Grünling, Bechstein.
This bird is rather larger than the chaffinch, being six inches in length, of which the tail measures two and a half; the beak five lines in length. The iris is dark brown; the shanks are eight inches in height, and of a bluish flesh colour. The prevailing colour of the plumage is yellowish green, lighter on the lower part of the body, still more so on the rump and breast, and shading to white on the belly.
The female, which is smaller, is still more distinguished by the greenish brown of the upper part, and the ash-colour rather than yellowish green of the lower part of the body; she has besides some yellow spots on the breast, and the whole belly is rather white than yellow.
