Red-crowned cranes are breeding at China's Zhalong Reserve, the world's largest habitat for these endangered birds.

Red-crowned cranes at China's Zhalong National Nature Reserve in Heilongjiang are in their breeding season, with many new offspring born. Spanning 2,100 square kilometers, the reserve is the world's largest habitat for these endangered birds and a major rewilding site for captive-bred cranes. Known as the "home of red-crowned cranes," it plays a crucial role in their conservation.
