This document contains a version of the now well-known, and much discussed world list of bird names by Charles Sibley and the late Burt Monroe, Jr. In essence, it is the names used in their 1990 Distribution and Taxonomy of Birds of the World and its 1993 Supplement, which were later combined to become the Checklist. Full references to these sources and some more are provided below. Including the Supplement, the list is up-to-date through May 1992. But it has been updated for obvious typographic errors through to February 1998. The list does not reflect new taxonomic insights obtained since 1992.
