Taiwan is a semi-tropical island located on the curved line of islands in the Pacific Ocean on the outskirts of the Chinese mainland. The island is blessed with abundant natural resources, including several high mountains over 3,000 meters above sea level, primary forests, lakes, rivers, wetlands, farms, reefs, etc. Its complex geographical environment makes it well-suited for many migrating birds of East Asia. Such a special island ecology makes Taiwan unique. Because Taiwan is an island separated from the mainland, endemic species evolved over the long term, and the island has formed a distinctive ecology of wildlife.
