Guizhou wetland welcomes wintering rare birds

GUIYANG — With a camera snapping photos of migratory birds, Liu Guanghui starts his daily patrol in the Caohai National Nature Reserve in Guizhou province.

The 54-year-old is vice-captain of the team patrolling Caohai Lake, a primary wetland area in the Yi, Hui, and Miao autonomous county of Weining. It is one of the largest wintering locations for black-necked cranes, a species under first-class national protection.

"The priority of our current work is to dynamically record the populations of the migratory birds and observe their activities to help them overwinter," say Liu, who has been patrolling the area for more than three decades.
