A spectacular wave of migrating gray cranes has arrived in Emin County, northwest China's Xinjiang Uygur Autonomous Region. Thousands of birds fill the spring sky, soaring in graceful arcs, foraging, and resting in the warm sunshine. A nationally protected species, the gray crane makes its annual stopover in northern Xinjiang during migration. The breathtaking sight reflects the region's improving ecosystem, with healthier habitats turning the area into a vital sanctuary for migratory birds.
