Ensuring birds have a safe passage and that poachers take flight

The day starts early for Tang Shengli, a bird protection volunteer in Lanshan county, Yongzhou, Hunan province. At about 5 am, the 60-year-old is in uniform and ready to start his day's work protecting and recording migratory birds. Located on the northern side of the Nanling Mountains, Lanshan is an important passageway for migratory flocks.
