Prepared by The American Ornithologists' Union, this "Check-List of North American Birds," is subtitled: "Constituting the 'Systema Avium' for North America North of Mexico." Also on title page, a line that reads, "Zoological Nomenclature is a means, not an end, of Zoological Science."
This book is a valuable find for the serious birder -- an excellent reference work that includes the original sources of names of birds, their species, and genera.
