Checklist: 7th Edition and Supplements

The 829-page hardbound volume, published in 1998, may be purchased from Buteo Books or downloaded in PDF format (PDF files listed below: file size up to 13 MB):

Note that the documents above do not as yet incorporate changes made in the Supplements to the Checklist. Annotations to the book PDFs are planned for the future, but for now, users of the book must check the supplements or online list to determine whether changes have been made.


The last edition of the Checklist to include subspecies was published in 1957 (5th edition). Although a complete revision of North American avian subspecies has not been done, we refer readers to Avibase and the Birds of North America for more up-to-date treatments of subspecies. The Birds of North America project is systematically revising subspecies account for North American birds.
