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. BREEDING.--The goldfinch prefers building in large orchards, at the tops of trees, on weak and terminal branches. It makes the most beautiful nest of any of our birds, except the chaffinch, it being finely rounded, very elegant and firm. The outer part is constructed of fine moss, lichens, stalks of grass, and slender twigs; the whole being interwoven with the greatest nicety. The interior is lined with wool, horse-hair, and the cotton or down of the thistle[47], or willow. The female has rarely more than one brood in the year, unless she has been disturbed, and, in this case, the number of eggs is always diminished; on this account goldfinches never appear to increase in number. On a sea-green ground, the eggs have pale red spots and speckles, mingled with streaks of reddish black, which often form a circle at the large end. The parent birds disgorge the food into the young ones' throats. Before the first moulting the heads of the young birds are grey. If it is only wished to take male birds from the nest, all that have a whitish ring round the root of the beak, must be left. They must be brought up on poppy-seed and the crumb of white bread, soaked in milk or water. Of all the natural songs of birds, they imitate most easily and perfectly that of the canary; they also pair with the canary, and produce together fruitful young ones. For this purpose, a male goldfinch is paired with one or
