China's vast territory and diverse climate provide ideal conditions for birds to thrive. The country is home to over 1,500 species of birds, making it one of the countries with the richest bird biodiversity in the world. An issue has arisen in the grassy plateau regions though, as some raptor species prefer nesting in elevated locations, but these regions lack tall trees.

As a result, the birds have been nesting in transmission towers, and the materials being used to build their nests like sticks and metal wires are causing power line malfunctions. To ensure power grid safety while protecting birds, the State Grid Corporation of China launched a public welfare project in 2016 to develop artificial bird nests around the transmission towers and lines that are suitable for the birds to nest in. 1 : A raptor flies away from an artificial bird nest on the Ruoergai Grassland in southwest China's Sichuan Province.
