It feeds on the ground, and, as stated by Mr. Townsend, may be seen in flocks of from sixty to a hundred together. It was, so far as their observations went, found inhabiting exclusively the wide grassy plains of the Platte. They did not see it to the west of the Black Hills, or the first range of the Rocky Mountains. To Mr. Nuttall’s account Mr. Townsend adds that this bird is strictly gregarious, that it feeds on the ground, around which it runs in the manner of the Grass Finch, to which, in its habits, it seems to be somewhat allied. Mr. Townsend adds that, as their caravan moved along, large flocks of these birds, sometimes to the number of sixty or a hundred individuals, were started from the ground, and the piebald appearance of the males and females promiscuously intermingled presented a very striking and by no means unpleasing effect. While the flock was engaged in feeding, some of the males were observed to rise suddenly to considerable height in the air, and, poising themselves over their companions with their wings in constant and rapid motion, continued nearly stationary. In this situation they poured forth a number of very lively and sweetly modulated notes, and, at the expiration of about a minute, descended to the ground and moved about as before. Mr. Townsend also states that he met with none of these birds west of the Black Hills. Mr. Ridgway also mentions that though he found these birds very abundant on the plains east of the Black Hills, he met with only a single specimen to the westward of that range. This was at Parley’s Park, among the Wahsatch Mountains. Dr. Gambel, in his paper on the Birds of California, states that he met with small flocks of this handsome species in the bushy plains, and along the margins of streams, during the winter months. And Dr. Heermann states that he also found this species numerous in California, New Mexico, and Texas. Arriving in the last-named State in May, he found this species there already mated, and about to commence the duties of incubation. Mr. Dresser found these birds common near San Antonio during the winter. In December he noticed several flocks near Eagle Pass. They frequented the roads, seeking the horse-dung. They were quite shy, and when disturbed the whole flock would go off together, uttering a low and melodious whistle. In May and June several were still about near Howard’s Rancho, and on his return from Houston, in June, he succeeded in shooting one in its full summer plumage, when its specific name is peculiarly appropriate. He does not, however, think that, as a general thing, any of them remain about San Antonio to breed.
