HBW and Birdlife International Illustrated Checklist of the Birds of the World: Passerines

The first ever Illustrated Checklist of the Birds of the World is really two works in one. It is a complete checklist whose taxonomy incorporates the most up-to-date information and an exhaustive methodology (Tobias et al. 2010) in an entirely systematic and consistent way. At the same time, it contains illustrations and distribution maps for every bird species in the world. This includes the original artwork from the HBW series, as well as hundreds of new illustrations, all in two compact volumes (Volume 1: Non-passerines & Volume 2: Passerines).
