The following varieties are better established:--1. The goldfinch, with a yellow breast; 2. With a white head; 3. With the head black--four young ones of this variety were found in the same nest; 4. The white goldfinch; 5. And the black goldfinch, this being either entirely black, which often happens in a cage, from giving it too much hemp seed, or from old age; or it only retains the yellow spot on the wings, which is also occasioned by captivity. M. Schilbach, superintendant of the menagerie of Cassel, tried an experiment on a whole brood. He deprived the birds of the light of the sun, even covered the cage with a piece of cloth, and, by these means, obtained very black goldfinches, with only the yellow spot on the wings; but they changed colour after moulting. Those in which the black does not change are very old. It is, in fact, a sign of approaching death.
HABITATION.--In their wild state goldfinches are found in all parts of Europe, frequenting orchards, brambles, thickets, and mountainous districts, interspersed with wood and fields, during the summer. These birds are stationary, not changing their haunts in winter; they merely assemble in the autumn in families, or rather in little flocks of fifteen or twenty, seeking here and there places abounding in thistles, and only when the snow becomes too deep leaving such localities for others more accessible.
In the house, if kept in a cage, this should be a square one, because these birds do not like hopping about the upper part, as they would be forced to do, if in a bell-shaped cage, and also inclined to swing round. When they run on the floor they should be given a small artificial tree for a roost; for they like to perch on this whilst singing as well as sleeping.
FOOD.--Their food, when wild, consists of all kinds of small seeds, such as lettuce, goats'-beard, scorzonera, thistle, radish, and canary seed.
With us, in the house, they are principally fed on poppy, hemp seed, properly varied with lettuce, rape, and canary seed. If allowed to range, the second universal paste agrees very well with them. I have a goldfinch, which appears in good health, and eats not only of all the vegetables brought to table, but also meat, though, in their wild state, these birds never touch insects[46]. They must have green food occasionally, such as chickweed, water-cresses, lettuce, or endive. These birds feed largely, when loose in the room, rarely leaving the food-dish, and driving off, if they can, with loud cries, any of their companions who wish to approach. They will allow those birds, however, to feed peaceably with them, that bear some analogy to their species, at least, in the nature of the stomach, such as the canary, siskin, and especially the lesser redpole, without distinction of male or female.
