Mr. Audubon says that during the winter these birds are quite common throughout Louisiana, and the country about the Mississippi, as far as Kentucky. They begin to depart from the South early in March, and move slowly northward as the season advances. He states that they begin to nest in May, and raise three broods in a season. This is not the case in New England, where they do not often have more than a single brood. [Illustration: PLATE XXVII. 1.

Pa., 937.] Their nests are constructed in a manner very similar to those of the Chipping Sparrow, loosely made of a few stems of vegetables, grasses, and sedges, and lined with hair or fine rootlets. Those placed on the ground are larger and more bulky, and those wrought into the twigs of a bush are made with more care and neatness of interweaving. The eggs are usually five in number, of an oblong-oval shape. The ground is a whitish clay-color, marked more or less fully with blotches of a ferruginous-brown. In some these markings are few, and arranged only about the larger end. In others they are generally diffused, and impart a deep ferruginous color to the whole egg, and disguise or conceal the ground. They vary also in size,—in length from .70 to .63 of an inch, and in breadth from .52 to .50. Their usual size is .70 by .52. Two nests of this bird taken in Lynn, Mass., by Mr. George O. Welch, are characteristic of their usual style in architecture. One of these has a diameter of four and a height of two and a half inches. Its base, as well as the great mass of its periphery, is made of a very loose intertwining of minute stems of vegetables and dry grasses. The ends of these project from the exterior of the nest at the upper rim, and present a very peculiar appearance, as of an enclosure of palisades. The interior is lined with horsehair. The other is made of similar materials, of a less rigid character and closer texture. Its rim presents the same peculiarities of projecting ends, arranged like a fence above the nest itself. Its dimensions also are about the same. It is, however, much more compactly constructed, with thicker walls and a less open network of dry grasses, and stiff wiry stems of dried plants intermixed with a few pine leaves. The whole is very carefully and warmly lined with horsehair and the softer fur of small quadrupeds. These nests contained, one three, and the other four eggs. Spizella socialis, BONAP.
