NEW COPY, damage to dust jacket and cover. With the release of the 16th volume of the Handbook of the Birds of the World, this project has now been brought to completion. In the 20 years that have passed since this project started, a number of species genuinely new to Science have been described, and therefore are not featured in the 16 volumes of HBW. The Special Volume covers and illustrates all these species, 55 in total with texts, plates and distribution maps in typical HBW format. The Special Volume includes a global index to the collection, an indispensable and useful tool which will enable users to quickly find the specific species they are looking for in the more than 12,500 pages of the 16 volumes.
