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.
This bird is smaller than the siskin, its length not exceeding four inches and a quarter, of which the tail measures one inch and a third. The beak is short and thick, brown above and white below; the iris is dark chestnut. The shanks are six lines high, and are of a flesh colour. The plumage of the male very much resembles that of the grey canary; the front of the head, the circle round the eyes, a kind of collar, the breast and belly, are pale jonquil-coloured, mixed with a little green; the nape of the neck, the cheeks, the temples, and lesser wing-coverts, are of a canary green, mingled with rust colour and black.
The spots scattered over the plumage are not isolated, but united to each other by an undulating line; they are so small on the head, that it is only speckled.
It is necessary to examine the female very closely to distinguish it from the siskin, for, with the exception of a reddish grey tint, the colours are the same; but its beak is shorter, its tail longer, and its shape freer.
From my latest observations this bird appears to be the same as the citril finch; comparing them together in cabinets has confirmed my opinion; but that which has decided me is the testimony of my friend, Dr. Meyer, of Offenbach, who has often seen and even fed in his house several of these birds. From him I derive the rest of this article.
