As a vocalist the goldfinch does not rank high; but his lively, twittering song, uttered both on the perch and when passing through the air, and his musical call-notes, have a very pleasing effect, especially when the birds are seen in the open country in bright, sunny weather. Unhappily, it is not now very easy to see them, except in a few favoured localities, owing to their increasing rarity. For the goldfinch is a favourite cage-bird, and so long as bird-catching is permitted to flourish without restriction, this charming species will continue to decrease, as it has been decreasing for the last fifty years and upwards. Siskin. Chrysometris spinus. Crown black; a broad yellow streak behind the eye; the plumage variegated with grey, dusky, and various shades of green; wings dusky, with a transverse greenish yellow bar, and a black one above, and a second black bar across the middle of the tertiaries; tail dusky, the base and edge of the inner web greenish yellow. _Female_: colours less bright, and no black on the head. Length, four and a half inches. * * * * * The siskin, or aberdevine, as it is also called, is known to us as a winter visitant, but it is better known as a cage than a free bird. In the British Islands it breeds in various places in Scotland, in pine and fir woods; it has also been found breeding in various localities in England and Wales. In Ireland it is not so common as in England. The siskin is a pretty, active, musical little bird, somewhat tit-like in its manner of seeking its food, its sociability, and the various positions it assumes in its search for small insects and seeds in the higher branches of a tree, or when clinging to the terminal twigs. As a caged bird his song is a small musical twittering; but in a wild state, in the pairing season, the male has a more charming performance, for he then soars about the tree, and, with fluttering wings and outspread tail, floats down singing to his perch. The nest is built in a pine or fir tree at a considerable height from the ground, and so hidden as to make it very hard to find. There is a legend in some districts on the continent of Europe that the siskin places a small stone among its eggs, which renders the nest invisible. This legend reminds me of a belief of the peasants of southern South America, that the rail-like, spotted tinamou--a bird that easily eludes one’s sight among the grey and yellow herbage--has the faculty of making itself invisible. The primitive mind is much given to explanations of this kind. The nest, placed as a rule in the fork of a horizontal branch, is composed of rootlets and moss, on a foundation of bents and twigs of heather, and is lined with fine dry grass and a little vegetable down, sometimes with a few feathers. Five or six eggs are laid, pale bluish green in ground-colour, and spotted with dark reddish brown and pinkish grey under-markings.
