Hab. Valley of Rio Grande and Gila. Abundant on the Llano Estacado, and at Eagle Pass, Texas (Dresser, Ibis, 1865, 494). Colorado (Aiken).
In the white bases to the feathers of the neck, etc., there is a resemblance in this species to the C. leucognaphalus of Porto Rico; but the latter has entirely different proportions, blended instead of lanceolate feathers on the throat, exceedingly short instead of unusually long nasal plumes, and many other differences, and is in every feature totally distinct.
Habits. Of the distinctive habits or the extent of the distribution of the
White-necked Raven we have very little knowledge. It was first described by Lieutenant Couch, in 1854, from specimens obtained by him at Charco Escondido, Mexico, in May, 1853. Other specimens were afterwards procured by Dr. Kennerly, at Janos, Mexico, in 1855, and by Mr. Dresser at Eagle Pass, Texas, in March, 1864. The latter gives no notes as to its habits.
Dr. Kennerly’s note in regard to it is that it was not very common, and when seen was generally associated with the larger species of Raven. Lieutenant Couch merely mentions it as found in small numbers in Eastern Tamaulipas, generally near ranches.
Mr. J. H. Clark writes that this species does not seem to possess the cunning or wariness of its congeners. It was met with, in the greatest abundance, about watering-places. It was not found habitually in great flocks, though at the head of the Limpia many were congregated and flying about the face of an immense rocky mountain wall, where they were probably nesting. Their note he describes as coarse, and less shrill than that of the common Crow. He met with the supposed nest in an arborescent cactus.
Dr. Coues does not appear to have met with this species in Arizona, but Lieutenant Bendire writes to Professor Baird from Tucson, April 12, 1872, that it is the most common Crow or Raven there. This he discovered accidentally, finding that three fourths of the Ravens he shot proved to be of this species; the others were the Colorado race of the Raven. Specimens of this Crow were obtained at Fort Buchanan by Dr. Irwin, at Pecos River by Dr. Anderson, and in the Indian Territory by Mr. McCarthy.
An egg of this species, from Trout Creek, Texas, obtained June 20 by Charles S. McCarthy, measures 1.75 inches in length by 1.25 in breadth. The ground-color is a light grayish-green, and is pretty uniformly marked with fine dottings of mingled purple and brown.
