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.
