Hab. Mexico, just south of the Rio Grande; Fort Whipple, Ariz. (Coues); Cape St. Lucas.

This species is about the size of S. pusilla and S. socialis, resembling the former most in its still longer tail. This is more deeply forked and divaricated, with broader feathers than in either. The wing is much rounded; the fourth quill longest; the first almost the shortest of the primaries.

Habits. This species is a Mexican bird, found only within the limits of the United States along the borders. But little is known as to its history. It is supposed to be neither very abundant nor to have an extended area of distribution. It was met with by Dr. Coues in the neighborhood of Fort Whipple, Arizona, where it arrives in April and leaves again in October, collecting, before its departure, in small flocks. In the spring he states that it has a very sweet and melodious song, far surpassing in power and melody the notes of any other of this genus that he has ever heard.

Dr. Coues furnishes me with the following additional information in regard to this species: “This is not a common bird at Fort Whipple, and was only observed from April to October. It unquestionably breeds in that vicinity, as I shot very young birds, in August, wanting the distinctive head-markings of the adult. A pair noticed in early April were seemingly about breeding, as the male was in full song, and showed, on dissection, highly developed

sexual organs. The song is very agreeable, not in the least recalling the monotonous ditty of the Chip Bird, or the rather weak performances of some other species of the genus. In the latter part of summer and early autumn the birds were generally seen in small troops, perhaps families, in weedy places, associating with the western variety of Spizella socialis, as well as with Goldfinches.”

Lieutenant Couch met with individuals of this species at Agua Nueva, in Coahuila, Mexico, in May, 1853. They were found in small flocks among the mountains. Their nest and eggs are unknown.
