The annual migration of Tibetan antelope is underway across the Qinghai-Xizang Plateau as mothers and their newborn calves begin the journey back from their calving grounds. Behind the breathtaking scenes, an integrated "sky-air-ground" monitoring network combines AI-powered cameras, remote drones and around-the-clock surveillance to track the migration in real time while rangers continue patrolling key corridors on the ground. Together, technology and human dedication are helping protect one of the world's most spectacular wildlife migrations.
