The filming crew of the documentary "CGTN Nature" recently captured footage of endangered crested ibises in Yang County, Shaanxi Province in northwestern China.

At one time, the crested ibises were widespread in Russia, China, Japan, and the Korean Peninsula. After suffering from habitat loss and unstable population size for a long time, there were only an estimated seven wild crested ibises left in the world in the 1980s.

They were found in Yang County, which later became the captive breeding center for the species. After more than 30 years of conservation efforts, the population of the crested ibis has been increasing steadily and there are over 3,000 crested ibises in China now.
