Seasoned amateur ornithologist Dr. Alan Peterson has put together this Zoological Nomenclature Resource on the Birds of the World. Based on Sibley & Monroe (Distribution and Taxonomy of Birds of the World, 1990) and the AOU Checklist (7th Ed.), the resource includes current valid scientific avian names. Zoonomen contains nomenclature information (including full citations) organized by Order (from Anseriformes to Upupiformes) for 2,073 Genera and 9,806 Species and may be browsed alphabetically. Two sections entitled Explanatory Notes and Reference List provide additional information, such as modifications in the taxonomic sequence, and additional bibliographical materials. This is a fine, clutter-free resource on zoological nomenclature.
