The Formation of Endemic Species of Birds

In the long course of history， enormous changes have made to the topography on the territory of China. The Tibetan Plateau has risen， island .and continental plates have been isolated.....Scientists have found that endemic birds often concentrate in one region while China's endemic birds concentrate in Tibetan Plateau， "Himalaya-Hengduan mountain" area as well as Taiwan， China and other places， which can be corresponded to the geological event in history.

The mountains and sea formed by these geological events are barriers insurmountable for some birds. After a long period of reproductive isolation and evolution， they gradually differentiated into different subspecies or new species， and followed the "ancient" habit of living in China， thus becoming today's China endemic bird.
