This glossary defines the common, generic, family, and order names of birds. It is primarily aimed at bird and nature lovers who seek definitions for unfamiliar bird names that they encounter in ornithological literature. It is also a valuable reference work for the interested non-specialists who would like a small definition for any unfamiliar bird name that they may come across in their day to day lives. An introduction to birds in general has also been provided, including brief accounts on feathers and flight, migration, evolutionary history, and classification of birds. The author has also written two other books on birds, ‘BIRDS: an introduction to the feathered wonders of nature'' and ‘Diversity and Resource Partitioning of Avifauna: a comparative study in forest and agricultural ecosystems,'' both published by VDM.
