The black-necked crane, an endangered species, is the only crane that inhabits and reproduces in high plateau, mainly breeding on the Qinghai-Tibet Plateau in China. It serves as both the flagship species of the high-altitude wetland ecosystem and an indicator of the ecosystem's health. During the summer, the Qinghai area of Qilian Mountain National Park, which straddles the Gansu and Qinghai provinces, becomes a breeding ground for these elegant cranes.
