The bird now before the reader is one of the most admired songsters of the western countries of North America. By competent judges, as we shall see in the course of the present article, he has been pronounced worthy of favorable mention, even when compared with our great sylvan vocalists, the Mocking Bird, and the Rufous Thrush, to both of which he can claim relationship, not distant. Viewed as the representatives of principles embodied, as it were, in the various forms or rather classes of animal life, a consideration by no means to be overlooked in the present age of zoological science, birds are the especial exponents of the principles of the beautiful, and, of all classes of animals, appeal most directly to the higher faculties of the human mind. Entire symmetry and elegance of form, gracefulness of motion, agreeable and varied colors, and the fact that of the vast circle of animal life, they alone possess vocal powers which are musical, have recommended this class, and tended to perpetuate its high estimation in all civilized countries. The flight of birds, never yet successfully imitated by the ingenuity of man (unlike in that respect the motions of fishes in their element), is a means of locomotion so entirely peculiar as always to have attracted attention, and, in past ages, wonder, even to such extent as to have assumed an aspect of superstition, not entirely ignorant nor reprehensible, because founded on facts of nature, manifesting itself in auguries and divinations, which commanded respect for centuries erroneously, but expanded into truth at last by the aid of the light of Inductive science. The conclusions of the learned and cultivated nations of antiquity, however apparently erroneous, are rarely without some foundation in and relation to truth, and in many cases are the origin of modern science. So the augurs were the first ornithologists, as the astrologers were the first astronomers. The poets have found in birds the most attractive of animals. There is scarcely one from the great Grecian era of taste and poetry to the present day, in whose productions passages do not occur, recognised as beautiful and deriving their essential character from this class of objects. Hebrew and Greek were alike in this respect, whether in the derivation of sacred symbols or of imagery in poetic allusion; the Dove of the former is of the same general character as the Peacock of Juno, or the Sparrows of Venus, poetic and truthful to nature and of the same origin. The Greek poets found in birds suitable accompaniments for the most sublime creations of their genius, their Deities. The greatest of Hebrew poets rejoices in the assurance that “the time of the singing of birds is come, and the voice of the Turtle is heard in the land.” [Illustration: Plate 42 The Curved-billed Thrush Toxostoma rediviva (_Gambel_)]
