twigs, wool, or moss, which they tore from the bark of the trees. It was curious to see the little creatures prepare the wool, with which the nest is lined, by holding it with the foot while pulling it out with their beak to render it soft and elastic. In some other instances that have come under our notice, the female alone constructed the nest, the male keeping near her during the whole time. When busy in the preparation of their dwelling, these little birds testify no uneasiness if watched or approached, though they have been known to leave a partially constructed nest, and commence another. The vicinity of water is always preferred in the choice of a tree on which to build. The nests vary considerably in their appearance. They are formed of twigs and moss, bound strongly together with cobwebs, and lined with feathers, hair, and various kinds of delicate fibres. The walls are very thick, and the central cavity deep. The breeding season usually commences about the beginning of June, but young fledged birds have been seen as early as May. The eggs, which resemble those of the Brown Linnet, differ remarkably from each other in size, shape, and colour, but are, for the most part, of a whitish-blue or blueish-green, marked with a variety of spots and veins. The female alone sits upon the eggs, remaining on the nest from the time that the first is laid. The Siskin has been known to breed in captivity. THE GOLDFINCH. The GOLDFINCH (_Carduelis elegans_) may be considered as the type of a group that has but few representatives, the only other species with which we are acquainted being an inhabitant of the West Indies. The Goldfinches are distinguished by their long, conical, compressed beak, bent slightly at the tip; short strong legs, tail of middle length, and variegated exterior. The feathers of both sexes are alike in their colouring, but the young bear no resemblance to the parents. The length of the male is about five inches, its breadth eight and three-quarter inches. The female is not quite so large. The tail measures two inches, and the wing two and a quarter inches from the shoulder to the tip. The plumage is most beautifully marked and ornamented (see Coloured Plate V.); the beak, which is flesh-coloured at the base and blue at the tip, is surrounded by a black circle, and this again is encompassed by a broader band of red. The back of the head and part of the otherwise white cheeks are black. The back is brown, the belly white; and the sides of the upper part of the breast light brown; the wings and tail black, streaked with white, and the quills golden yellow at the root. The two sexes are so much alike that it requires a practised eye to distinguish them, though the male has somewhat more red on the face and a deeper black upon the head than the female.
