Comments on the status of revived old names for some North American birds

We discuss 44 instances of the use of generic, specific, or subspecific names that differ from those generally in use for North American (sensu AOU 1957) birds. These names are generally older than the names presently used and have been revived on the basis of priority. We examine the basis for the proposed changes and make recommendations as to which names should properly be used in an effort to promote nomenclatural stability in accordance with the International Code of Zoological Nomenclature.
