Tailor-birds are not confined to India or tropical countries. Italy can boast a species which exercises the same art. Mr. Gould has a specimen of this bird in his possession, and the Zoological Society have a nest in their Museum. This little bird, a species of the genus _sylvia_, in summer and autumn frequents marshes; but in the spring it seeks the meadows and corn-fields, in which, at that season, the marshes being bare of the sedges which cover them in summer, it is compelled to construct its nest in tussocks of grass on the brinks of ditches; but the leaves of these being weak, easily split, so that it is difficult for our little sempstresses to unite them, and so form the skeleton of the fabric. From this and other circumstances, the spring nests of these birds differ so widely from those made in the autumn that it seems next to impossible that both should be the work of the same artisan. The latter are constructed in a thick bunch of sedge or reed: they are shaped like a pear, being dilated below and narrow above, so as to leave an aperture sufficient for the ingress and egress of the bird. The greatest horizontal diameter of the nest is about two inches and a half, and the vertical is five inches. The most wonderful thing in the construction of these nests is the method to which the little bird has recourse to keep united the living leaves of which it is composed. The sole in the weaving, more or less delicate, of the materials, forms the principle adopted by other birds to bind together the walls of their nests; but this sylvia is no weaver, for the leaves of the sedges or reeds are united by real stitches. In the edge of each leaf she makes, probably with her beak, minute apertures, through which she contrives to pass, perhaps by means of the same organ, one or more cords formed of spiders' web, particularly that of their egg-pouches. Those threads are not very long, and are sufficient to pass two or three times from one leaf to another. They are of unequal thickness, and have knots here and there, which, in some places, divide into two or three branches. This is the manner in which the exterior of the nest is formed: the interior consists mainly of down, chiefly from plants, a little spiders' web being intermixed, which helps to keep the other substances together. The upper part and sides of the nest, that is, the external and internal, are in immediate contact; but in the lower part a greater space intervenes, filled with the slender foliage of grasses, and other materials, which render soft and warm the bed on which the eggs are to repose. This little bird feeds on insects. Its flight is rectilinear, but consists of many curves, with the concavity upwards. These curves equal in number the strokes of the wing, and at every stroke its whistle is heard, the intervals of which correspond with the rapidity of its flight.
