Uniquely, the present work will present in one place the vernacular names of the almost ten thousand birds of the world in about fifty languages. It should thus serve as a valuable reference work and source of information that has been scattered through field guides, scientific journals, coffee-table volumes and across the internet, often buried under all sorts of other data.The compilations draw on official or other generally recognized authority wherever possible, and alternates are given where space permits. While the very fact that such extensive lists may, just by their existence, in future carry some authoritative weight in standardization of bird names, that is not its primary purpose, which is to present in a more useful format the nomenclature that is already in use.
