Elliott Coues

As originally projected for publication in a different connection, the work consisted merely of a report upon the peculiar features of bird-life in the area under consideration, with biographies of the species not treated in the "Birds of the Northwest". But the author's resources have proved to be so largely in excess of the requirements of such a report that the work has outgrown the limits of a single volume, and become a full exposition of our present knowledge of the subject, by the incorporation of much technical matter concerning North American ornithology at large, hitherto the private possession of the author and now first made accessible to the public.
