It is, however, entirely erroneous to attribute a noble or generous character to any of the predatory animals, though from an early period of history several species have been so regarded. On the contrary, there is in all these classes, whether of birds or of other animals, a marked absence of the very traits which are in some measure assigned to them, and even more unmistakably so in some of the more celebrated, as the Eagles and Lions, than in the more humble species. Yet the rapacious animals present a study in natural history of deep interest. Owing the sustaining of their existence for the greater part to rapine and violence, yet holding an important place in the great design of the physical universe, they appear to personate a principle, if we may be allowed to use the expression, involving one of the most momentous and mysterious of problems, the existence of evil in the world. The prowling and treacherous Lion, and the robber Wolf, have unfortunately but too strong analogies in that race which is the head of the visible creation, and they and their kind everywhere present the same intrinsic meanness which is characteristic of violence and injustice, of vice and of crime amongst men. The bird now before the reader is, so far as known, exclusively a Western species. It was first made known to American naturalists by Mr. Edward M. Kern of this city, who, when attached as artist to Colonel Frémont’s Expedition of 1846, obtained it in California and brought home specimens in a collection made by him, of the birds of that country. It had however been previously noticed and described as a bird of California by Professor Lichtenstein, a distinguished European naturalist, in a paper on the natural history of that country, in the Transactions of the Royal Academy of Berlin (1838, p. 428). Since Mr. Kern, the only American naturalist who has noticed this bird is Dr. Heermann, who has met with it during both of his visits to California, but especially during his connection with a party under command of Lieut. Williamson, of the U. S. Topographical Engineers, which has recently completed an examination and survey for a route for a Railroad to the Pacific Ocean through the southern portion of the territory of the United States. For our present article, Dr. Heermann has with great kindness allowed us to make the following extract from his journal, kept during the survey to which we have alluded: “During a previous visit to California, I had seen this species in the valley of the Sacramento river, and had considered it as rare in that section of the country, but during the recent survey in which I have been engaged in the southern part of the state, I found it very abundant, and on one occasion saw five or six individuals in view at the same moment, in the mountains, about sixty miles east of San Diego. It was there much more frequently seen than any other species.
