The speciation and biogeography of birds provides a fresh insight into species formation in birds and of the factors that influence their geographical distributions. The book describes how bird species are formed and how they are defined and classified by taxonomists. It describes how the number and types of bird species vary from region to region across the world and how patterns of distribution are influenced by earth history. It also describes the role of contemporary ecological factors in influencing the current geographical ranges and migration patterns in birds.
