Recently, a large number of migratory birds have appeared in Zhejiang Xin'an River Wetland Park. Up to now, there are more than 10,000 migratory birds with nearly 20 species, such as oriental white stork, egrets, geese and swans, which are regular visitors here.

"The number of migratory birds found this year is the highest in history, especially the oriental white stork, the Class I national protected bird, is precious and rare. This shows that the ecological environment is becoming better for birds," said Zhu Kejing, a river chief of Yangxi Road Subdistrict Office in Jiande City, Zhejiang Province.

To protect the wetland park, the local government funded more than 30 million yuan (about $4.3 million) to enhance the integrity of the ecosystem. At the same time, the local community has also built greenways around the wetlands.

According to Ten Successful Stories of Waterbird Conservation in China in the 14th Conference of the Parties to the Convention on Wetlands (COP14), the number of black-faced spoonbills has increased from 300 in the 1980s to about 6,000 today. From the 1990s to the present, the number of black-necked cranes increased from 5,000 to more than 15,000, and the number of oriental white storks has increased from 3,000 to nearly 10,000, respectively.

There are nine major migratory corridors worldwide, four of which pass through China: the Western Pacific Flyway, the East Asia-Australasia Flyway, the Central Asia Flyway, and the West Asia-East Africa Flyway. China announced at the COP14 that it would promote international cooperation to protect the four migratory flyways.
