Migratory swans drawn to Xinjiang's ecological safe haven

Tourists snap pictures of swans at a riverbank in Korla, northwest China's Xinjiang Uygur Autonomous Region, on Dec. 8, 2021. For 15 years, hundreds have migrated to the city each winter. Relentless conservation efforts by municipal authorities have paid dividends in improving the environment and raising awareness of ecological protection, making Korla a top spot to get up close and personal with these elegant water birds as they swan around.
