State Grid Gansu Electric Power Company has stepped up efforts to protect migratory birds by integrating wildlife-friendly measures into power grid operations in Northwest China.

Gansu province is a key stopover and breeding ground for swans, herons, and cranes. In recent years, local power authorities have shifted from traditional bird deterrence methods to a more protection-oriented approach.

The company has launched a series of initiatives across major habitats, such as the Qilian Mountain National Nature Reserve, wetlands along the Lanzhou section of the Yellow River, and the Ziwuling National Nature Reserve.

Measures include installing insulation covers and bird-safe devices on transmission lines, as well as building artificial nests to encourage birds to settle in safer areas.

In Zhangye, where migratory birds once posed challenges by nesting on transmission towers, local power operators have adopted a refined management model covering more than 7,200 towers. Using 3D modeling and intelligent inspection technologies, they coordinate grid infrastructure with 56 bird activity zones. Patrol teams, assisted by drones and binoculars, regularly monitor bird movements, while customized nests and protective devices are installed to reduce electrocution risks.

During the spring breeding season, patrols are intensified across wetlands and forest areas. Local power companies also work with forestry and wildlife authorities on bird rescue, habitat restoration, and anti-poaching efforts.

To date, thousands of artificial nests have been installed, more than 100 transmission lines upgraded, and hundreds of wild birds rescued, helping create safer conditions for migratory species.
