Our Answer: overhead line bird diverters are devices installed on power lines to increase their visibility to birds. They are essential for bird collision mitigation and avian protection, as they help prevent birds, especially large species and those flying in flocks or at night, from striking the wires. Collisions with power lines are a significant cause of bird mortality worldwide, and by making the conductors more visible, these devices help safeguard wildlife and ensure the reliability of the electrical grid.
