Callipepla squamata.
Habits. This bird was first described as a Mexican species in 1830 by Mr. Vigors. For a long while it has been an extremely rare species in collections, and its history, habits, and distribution remained unknown until the explorations of the naturalists made in the surveys under the direction of the national government. It was first noticed within the territory of the United States by Lieutenant Abert, Topographical Engineer, who, in his Report of the examination of New Mexico, furnishes several notes in relation to this species. In November, 1846, he mentions that, after having passed through Las Casas, while descending through a crooked ravine strewed with fragments of rocks, he saw several flocks of this species. They were running along with great velocity among the clumps of the kreosote plant. At the report of the gun only three or four rose up, the rest seeming to depend chiefly on their fleetness of foot. Their stomachs were found to be filled with grass-seeds and hemipterous insects.

Captain S. G. French, in notes quoted by Mr. Cassin, mentions meeting with these birds, in the same year, near Camargo, on the Rio Grande. At Monterey none were seen; but on the plains of Agua Nueva, a few miles south of Saltillo, they were observed in considerable numbers. He afterwards met with them on the Upper Rio Grande, in the vicinity of El Paso. Though found in the same section of country with Gambel’s Quail, they were not observed to associate together in the same flock. Their favorite resorts were sandy chaparral and mesquite bushes. Through these they ran with great swiftness, resorting only, when greatly alarmed by a sudden approach, to their wings. They were very shy, and were seldom found near habitations, though once a large covey ran through his camp in the suburbs of El Paso.
Colonel McCall (Proc. Phil. Ac. V, p. 222) mentions meeting with this species throughout an extended region, from Camargo, on the Lower Rio Grande, to Santa Fé. They were most numerous between the latter place and Doña Ana, preferring the vicinity of watercourses to interior tracts. They were wild, exceedingly watchful, and swift of foot, eluding pursuit with surprising skill, scarcely ever resorting to flight even on the open sandy ground. For the table they are said to possess, in a high degree, the requisites of plump muscle and delicate flavor.
In a subsequent sketch of this species, quoted by Mr. Cassin, the same writer gives as the habitat the entire valley of the Rio Grande,—a territory of great extent from north to south, and embracing in its stretch between the Rocky Mountains and the Gulf of Mexico every variety of climate. This entire region, not excepting even the mountain valleys covered in winter with deep snow, is inhabited by it. It was found by him from the 25th to the 38th degree of north latitude, or from below Monterey, in Mexico, along the borders of the San Juan River, as high up as the Taos and other northern branches of the Rio Grande. He also found it near the head of the Riado Creek, which rises in the Rocky Mountains and runs eastwardly to the Canadian.
Wherever found, they are always resident, proving their ability to endure great extremes of heat and cold. In swiftness of foot, no species of this family can compete with them. When running, they hold their heads high and keep the body erect, and seem to skim over the surface of the ground, their white plume erected and spread out like a fan.
