Habits. This form, which appears to be confined to the southern portion of Texas and to the valley of the Rio Grande River, was first described by Mr. Lawrence in 1853. It has been taken in the neighborhood of San Antonio and on the Nueces River by Captain Pope; on Devil’s River by Major William H. Emory; at Fort Clark, on the Pecos River, near Laredo, Texas, at Matamoras, and near New Leon, Mexico, and in other localities, by Lieutenant Couch. According to Mr. Clark, they were very abundant in the valley of the Pecos, as well as in all Southwestern Texas. They were much like the common Virginia Quail in habits as well as in appearance, and to his ear the note of this bird was absolutely identical with that of the common Quail. He has often been a spectator of fights among the males of this variety. To this account Dr. Kennerly adds that he observed them everywhere in considerable numbers from the coast to the headwaters of Devil’s River, and also along the Pecos River; but farther west than this none were seen. In the open prairie lands great numbers were always found early in the morning in the road. The close resemblance of its habits to those of the common Partridge was also noticed.
This Quail was first observed by Dr. Heermann in abundance on the Pecos River, although seen some days previous to reaching that point. Their numbers increased as they neared civilization, and near San Antonio they became very plentiful. The call of the male bird is said to consist of two notes repeated at intervals, which are less loud, clear, and ringing than those of the common Ortyx virginianus. They feed on the open prairies on grass-seeds, grains, berries, and insects, and, if alarmed, take refuge among the scattered mesquite-trees and clumps of bushes. When hunted, they lie to the dog in the manner of the common species, and, if flushed, fly in a direct line, with a loud whirring noise, caused by the shortness and rapid motions of the wings. An egg of this bird, found by Dr. Heermann dropped upon the road, was in form and color like that of the common Quail, but smaller.
Mr. Dresser states that in Texas this bird is known as the “Common Partridge” of the country. He found it abundant everywhere in localities suitable to its habits. Near Matamoras it was very common, and was the only species of Quail he noticed there. At Eagle Pass and Piedras Negras, where the soil is sandy, the grass scanty, and cacti abundant, he saw only one bevy, but plenty of the Callipepla squamata. Near San Antonio only this Quail is found, nor did he observe any other species in travelling towards the northeast. Amongst the Bandara Hills, where he met with the Massena Partridge, he also found the Texan Quail in the valley and near the maize-fields. In travelling from Brownsville to San Antonio the Texan Quail was everywhere abundant except in the sand-deserts. This species was found to be rather irregular as to its breeding-season, as he found young birds near Matamoras early in July, and in September again met with quite young birds near the Nueces River, and Dr. Heermann informed him that he had likewise procured eggs near San Antonio late in September. He obtained a set of their eggs taken near San Antonio, which are very similar to those of the Ortyx virginianus, but are slightly smaller.
