ATTRACTIVE QUALITIES.--Their plumage and song are both attractive, though with the latter several tones are mingled, that somewhat resemble the noise made by a stocking-loom. This makes them great favourites with stocking-weavers. They imitate tolerably the song of other birds, such as that of the tit, the chaffinch, and the lark; but they cannot give a musical air. Their carolling is only interrupted during moulting, and very much tends to excite their companions to warble in their turn. The loss of their liberty affects them so little, that they will eat as soon as let out of the hand, after being caught, and on the second day will allow any one to approach their cage without alarm. They are soon taught to draw up little buckets, and many other little manoeuvres that they execute gaily; there is no difficulty in accustoming them to go and return if the winter is chosen; the cage should be kept open at the window, and hemp and poppy-seed scattered at the entrance; they will return there in general, and bring several companions with them. This plan will not succeed so well in March, September, and October, the time when these birds roam through the country in search of food, though I have seen some tamed in this manner return after a long absence. THE RING SPARROW. Fringilla petronia, LINNÆUS; La Soulci, BUFFON; Der Graufink, BECHSTEIN. Independently of the beak, this bird may be taken for a female yellowhammer, as it resembles it so much in its shape and plumage. Its length is five inches three-quarters, of which the tail measures two. The beak, five lines long, is thick at the base, grey brown above, and white below. The feet, ten lines high, are grey brown; the whole head is of a reddish ash-colour, but a dirty white ring surrounds it from one eye to the other. The female is greyer on the upper part of the body, and the front of the neck is only pale yellow. OBSERVATIONS.--Ring sparrows are found in most European forests, or woods; they are common enough in several parts of Germany[51], those that inhabit the northern parts removing in winter; but the others are stationary. They live on seeds and insects like the house sparrow, and make their nests in hollows of trees. In the house they are fed on rape and poppy-seeds; they also readily eat the first universal paste. They are less prized for their warbling, which is insignificant, than for their beauty or rarity. THE SERIN FINCH. Fringilla serinus, LINNÆUS; Le Serin vert, ou le Cini, BUFFON; Der Girlitz, BECHSTEIN.
