Elliot described his aims for this work in the preface:

"Since the time of Wilson and Audubon, no work has been published upon American Ornithology, containing life-size representations of the various species that have been discovered since the labors of those great men were finished. The valuable productions of Cassin, as well as the revised edition of the ninth volume of the Pacific Rail Road Report, the joint labor of Messrs. Baird, Cassin and Lawrence had indeed appeared...but no attempt had been made to continue the works of the first great American naturalists in a similar manner [i.e. with the birds represented full-size where possible]....It was, therefore, with the desire to contribute...towards the elucidation of the comparatively little known species of the Birds of North America, their habits and economy, as well as to render their forms familiar so far as life-size representation of them might serve to do, that I undertook the present publication."

The work includes 72 handcolored lithographed plates, including 55 by Elliot, and 15 by Joseph Wolf (1820-1899).

This work contains 36 plates by lithographed Joseph Smit from drawings by Joseph Wolf, and handcolored by J.D. White. Wolf was regarded as the greatest bird artist of his time. Among the birds of paradise there are some of the most colorful and spectacular birds, and these plates (with those of the male pheasants) proved that Wolf was equally talented at painting exotic, highly colourful birds ... and the published prints show the extraordinary coloration of the birds of paradise, including iridescent feathers’ (K. Schulze-Hagen & A. Geus, Joseph Wolf (1820-1899) animal painter, 212). In the preface of the book Elliot comments, "The drawings of Mr. Wolf will, I am sure, receive the admiration of those who see them; for, like all that artist's productions, they cannot be surpassed, if equalled, at the present time. Mr. J. Smit has lithographed the drawings with his usual conscientious fidelity, and his share of the work has left me nothing to desire... In the colouring of the plates Mr. J.D. White has faithfully followed the originals; and in the difficult portions where it was necessary to produce metallic hues, he has been very successful."
