Excerpt from Evolution of Colors of North American Land Birds The present paper has been written more with the hope of stimulating thought and inciting research in a new and as yet almost untrodden field of ornithological inquiry, than with the expectation of reaching definite results. The subject is as yet too new and difficult to be reduced to even the semblance of an exact science, and accordingly all the views here set forth are more or less provisional and tentative. I have constantly proceeded upon the assumption that a poor theory is better than no theory, provided it be not considered as final, since it affords an opening wedge for the further study of a subject. Accordingly many of the views here set forth are hardly to be considered as more than guesses, and it is expected that future study will serve to show their fallacy. If they lead to this further study, however, and to more exact and comprehensive work by others, I shall be glad to see them overturned and their places filled by more worthy hypotheses. In the preparation of the work I have received much valuable assistance, which I here take pleasure in acknowledging. Much of the examination of specimens was done at the United States National Museum, the authorities of which kindly placed their collection of birds at my disposal. To Mr. Robert Ridgway I am indebted for innumerable personal favors during my stay in Washington. His Manual of North American Birds has formed the systematic basis for this paper.

Excerpt from A History of North American Birds, Vol. 3 The group of birds usually known as the Raptores, or Rapacious Birds, embraces three well-marked divisions, namely, the Owls, the Hawks, and the Vultures. In former classifications they headed the Class of Birds, being honored with this position in consequence of their powerful organization, large size, and predatory habits. But it being now known that in structure they are less perfectly organized than the Passcres and Strisorcs, birds generally far more delicate in organization, as well as smaller in size, they occupy a place in the more recent arrangements nearly at the end of the Terrestrial forms. The complete definition of the order Raptorcs, and of its subdivisions, requires the enumeration of a great many characters; and that their distinguishing features may be more easily recognized by the student, I give first a brief diagnosis, including their simplest characters, to be followed by a more detailed account hereafter. Common Characters. Bill hooked, the tipper mandible furnished at the base with a soft skin, or "cere," in which the nostrils are situated. Toes, three before and one behind. Raptores. Strigidae. Eyes directed forwards, and surrounded by radiating feathers, which are bounded, except anteriorly, by a circle or rim of differently formed, stiffer feathers. Outer toe reversible. Claws much hooked and very sharp. Legs and toes usually feathered, or, at least, coated with bristles. The Owls. Falconidae. Eyes lateral, and not surrounded by radiating feathers. Outer toe not reversible (except in Pandion). Claws usually booked and sharp, but variable. Head more or less completely feathered. The Hawks. Cathartidae. Eyes lateral; whole head naked. Outer toe not reversible; claws slightly curved, blunt. The Vultures. The preceding characters, though purely artificial, may nevertheless serve to distinguish the three families of Raptores belonging to the North American Ornis; a more scientific diagnosis, embracing a sufficient number of osteological, and accompanying anatomical characters, will be found further on.
