Black-necked cranes seen along Yarlung Zangbo River

A group of black-necked cranes walk along a bank of the Yarlung Zangbo River in Tibet autonomous region, Nov 22, 2015. Tibet has made great efforts in recent years to protect habitats for local species. As living conditions of the black-necked crane have significantly improved, a good number fly to the river valley area of Tibet to spend the winter. The black-necked crane, which is peculiar to the plateau area and is also an endangered species, is under the first grade of state protection.[Photo/Xinhua]
