PREFACE.
Love of the birds is a natural passion and one which requires neither analysis nor defense. The birds live, we live; and life is sufficient answer unto life. But humanity, unfortunately, has had until recently other less justifiable interests—that of fighting pre-eminent among them—so that out of a gory past only a few shadowy names of bird-lovers emerge, Aristotle, Pliny the Elder, Ælian. Ornithology as a science is modern, at best not over two centuries and a half old, while as a popular pursuit its age is better reckoned by decades. It is, therefore, highly gratifying to those who feel this primal instinct strongly to be able to note the rising tide of interest in their favorite study. Ornithology has received unwonted attention of late, not only in scientific works but also in popular literature, and it has taken at last a deserved place upon the curriculum of many of our colleges and secondary schools.
