This dictionary gives the derivation and meaning of all valid scientific bird names. Each part of the name is defined separately so that Passer domesticus, for example, will not be found as such, but both Passer and domesticus are explained in their respective alphabetical places. The usefulness of the dictionary will thus not be affected by future taxonomic revisions of generic or species names. About 8500 names are defined, including a selection of historical synonyms. Many unusual details emerge from the author's meticulous work in tracking down obscure meanings. A short but informative introduction explains the history and purposes of scientific nomenclature and the basic features of Latin in this context. It also discusses the ways in which birds have been named for their appearance, for a person or place, or some aspect of their habitat, behaviour, food, or voice, or with reference to their native-language name. This book should prove a valuable reference source for everyone whose work or interests bring them into contact with birds.
