Please choose a Zoogeographic region, from the list on the left, or from the map below.

Within the geographic regions will be found field guides, state and regional handbooks, site guides, checklists and other books pertaining to specific areas or localities. The Zoogeographic distribution is based on The Speciation and Biogeography of Birds by Ian Newton, which is "concerned mainly with the process of species formation in birds, and with the factors that affect their geographical ranges. The current distributions of species depend not just on prevailing conditions, but also on past conditions which have enabled species to reach the areas they have or eliminated them from areas formerly occupied."

This map is of utmost importance to birders and Ornithologists because the physical features of any region, and the accessibility of other regions, can greatly affect the evolution of species, making the species in Southern China, for example, south of the Himalayas, vastly different from their northern counterparts just over the mountains in the Palearctic region, or the avifauna north of the Sahara different from that south. This map delineates the regions by the geographic boundaries and therefore, by the differences the birds display from one region to another.
