Nov.14,2018--In recent years, Tibet Autonomous Region has continuously carried out the ecological protection work, and ecological environment has been improved, which have provided a good environment for black-necked cranes as well as migratory birds to inhabit. Flocks of black-necked cranes fly to the plateau for overwintering in winter, which is a good moment for shutterbugs  and people to appreciate black-necked cranes. [Zhi Xinghua, Zhu Nan]
