Mr. Audubon says that on his return from Florida, in June, 1832, travelling through both the Carolinas, he observed many of these Finches on the sides of the roads cut through the pine woods of South Carolina. They filled the air with their melodies. He traced them as far as the boundary line of North Carolina, but saw none within the limits of that State. They were particularly abundant about the Great Santee River.
This Finch, hitherto assumed to be an exclusively southeastern species, has
recently been detected by Mr. Ridgway in Southern Illinois, where it is a summer resident, and where it breeds, but is not abundant. It inhabits old fields, where, perched upon a fence-stake or an old dead tree, it is described as chanting a very delightful song. It was first taken on the 12th of July, 1871, on the road about half-way between Mount Carmel and Olney. The bird was then seen on a fence, and its unfamiliar appearance and fine song at once attracted his notice as he was riding by. As several were heard singing in the same neighborhood, it seemed common in that locality, and as a young bird was taken in its first plumage there is no doubt that it is a regular summer visitant of Southern Illinois, and breeds there. Mr. Ridgway speaks of its song as one of the finest he has ever heard, most resembling the sweet chant of the Field Sparrow, but is stronger, and varied by a clear, high, and very musical strain. He describes its song as resembling the syllables thééééééé-til-lūt, lūt-lūt, the first being a very fine trill pitched in a very high musical key, the last syllable abrupt and metallic in tone.
The food of this species, Dr. Bachman states, consists of the seeds of grasses, and also of coleopterous insects, as well as of a variety of the small berries so abundant in that part of the country. He speaks of its flight as swift, direct, and somewhat protracted, and adds that it is often out of sight before it alights.
Dr. Coues did not meet with this Sparrow in South Carolina, but he was informed by Professor Leconte that it occurs about Columbia and elsewhere in the State, frequenting open pine woods and old dry fields.
Dr. Bryant met with its nest in Florida, April 20. It was similar, in construction, to that of the Savannah Sparrow, and contained five eggs. It was the only Sparrow found by him in the pine barrens near Enterprise, and was only seen occasionally, when it was a very difficult bird to shoot, as it runs round in the grass more like a mouse than a bird, and will not fly until almost trodden on, then moving only a few feet at a time.
The nests of this bird, found by Dr. Bryant in Florida and by Dr. Gerhardt in Northern Georgia, were all placed upon the ground and concealed in tufts of thick grass, and constructed entirely of coarse wiry grasses, with no other lining than this material. The eggs, four in number, are of a pure, almost brilliant white, of a rounded oval shape, and measure .74 by .60 of an inch.
