As spring comes, black-necked cranes left the Caohai national nature reserve in Weining Yi, Hui and Miao autonomous region in southwest China's Guizhou province one after another. In recent years, Caohai nature reserve has accommodated more than 700 black-necked cranes during winter, and become the world's densest habitat for black-necked cranes to live through the winter.

Caohai nature reserve has been listed as the first-grade wetland in the national biodiversity protection project. In recent years, the awareness of environmental protection among the local farmers has been strengthened. They no longer catch and kill birds and some farmers voluntarily save the wounded black-necked cranes every year. The restoration of water areas in Caohai region accelerates the development of biodiversity and provides the black-necked cranes and other migrant birds with food, creating a favourable condition for the black-necked cranes coming from afar to live through the winter here.

Caohai nature reserve has now become an important habitat for migrant birds to live through the winter, with various birds living there amounting to 184 sorts. Among the total birds there, there are seven kinds of first-grade state protected birds including black-necked cranes, and second-grade state protected birds 20 kinds. Particularly, the black-necked crane, which only has 6,000 worldwide, multiplies and inhabits in Qinghai-Tibet plateau, Yungui plateau and northern part of Sichuan province in China.
