Bosten Lake in northwest China's Xinjiang Uygur Autonomous Region is witnessing the peak breeding season of migratory birds.

Video footage shows that some cormorants and egrets' eggs have already hatched. Some chicks are crawling in their waterborne nests or calling for food from their parents.

The lake is the largest inland freshwater lake in China.
