A large group of blue sheep climbing mountain rocks were captured by cameras in the Qumalai County area of the Sanjiangyuan National Park in northwest China's Qinghai Province.Blue sheep are under the second-level state protection in China.Blue sheep are a species of vertical migration, and have excellent rock climbing skills.The 100-meter cliff was the most dangerous part of the journey for the sheep to travel between their habitat and the water source, according to the ecological protection staff of the Sanjiangyuan National Park.Since the beginning of March, the sound of the blue sheep climbing cliffs has been frequently heard in the canyons in Qumalai County.
