Caohai National Nature Reserve in Weining County, southwest China's Guizhou Province is one of the wintering locations of the black-necked cranes. Staff members of the nature reserve have planted vegetables, such as carrots, potatoes and cabbage, to help the birds get through winter.

There are seven main habitats of black-necked cranes in the nature reserve, and those who arrived have mainly gathered at wetlands and swamps on the east, south and southwest. Latest research shows that more than 800 black-necked cranes are now there. And the number of other winter birds, such as grey cranes, bar-headed geese and ruddy shelducks is over 50,000.
