Why is Beidaihe called "one of the four bird watching places in the world"?

Beidaihe Wetland named by the International Wetland Protection Organization is a coastal beach wetland. Its good ecological environment has attracted nearly 1/3 species of birds from all over the country to thrive here, and 4 12 species of birds have been found, including nearly 70 species of national key protected animals. It is a stopover for migratory birds between Siberia, China, the Philippines and Australia. "Thousands of birds near the sea" is a unique grand occasion in Beidaihe. Therefore, Beidaihe Wetland is called "one of the four largest bird watching places in the world". I'm glad my answer can help you. Thank you for your adoption.
