“The stomachs of all the specimens that I examined of this bird were filled with the grass-hoppers and large black beetles found on the plains. The nest, built on the branches of the cactus, is formed of loose sticks, thrown negligently together, in the same manner as that of the yellow-billed Cuckoo of the United States (_Coccyzus americanus_). It contains two large, nearly spherical, white eggs. “I have never witnessed the following, but was gravely assured of its truth by several old Californians: It is said that this bird, on perceiving the rattlesnake coiled up asleep, will collect the cactus and hedge him around in a circle, out of which he is prevented from escaping by the prickly points opposing him on every side; and becoming enraged, strikes himself, and dies from the effects of his self-inoculated venom. “This bird is common in Western Texas and on the Rio Grande.” This remarkable bird has been found in the vicinity of Fort Webster, New Mexico, by Dr. Henry, and was also noticed in that country and in Texas by Mr. Clark, Mr. Schott, and Dr. Kennerly, and in Mexico by Lieut. Couch. Though neither of the authors above cited have mentioned that this bird devours reptiles as well as insects and snails, that fact is stated by Dr. Gambel in his paper on the Birds of California, in the first volume of the quarto Journal of the Philadelphia Academy, and it is so represented in some spirited sketches by Mr. Arthur Schott, now attached to the United States and Mexican Boundary Surveying party, whose drawings of this bird made in its native wilds are in the possession of our valued friend, Professor Baird, of the Smithsonian Institution. It is probable that although it may prefer insects, other small animals afford suitable food. Lieut. D. N. Couch, of the U. S. Army, to whom we have been indebted for other valuable contributions, has, with his usual kindness, added to our present article the following interesting notice of this bird as an inhabitant of Northern Mexico:— “This bird was first met with in Southwestern Texas, near the Rio Grande, where it is called ‘Prairie Cock’ by the inhabitants. Few or no opportunities occurred for me to observe it carefully, until I found myself in the dreary chapparel districts of Tamaulipas, and next beyond the Sierra Madre. “The chapparel is its home. Equally avoiding the forests of high trees or the open prairies,—in the former of which its short wings would preclude an easy flight to the branches, and in the latter, for the same reason, it would be unable to escape from the numerous hawks of various species that are ever hovering over the arid wastes of that region. Once only I saw it perched near the top of a stout Mesquite tree, though not many feet from the ground.
