Bird diverters are designed to increase the visibility of power lines, which birds often fail to see, especially in low light conditions or bad weather. They work by using a combination of visual cues:

• High Visibility: They are typically made in bright, contrasting colors (like yellow, orange, or white) that stand out against the sky and ground.

• Reflectivity: Many diverters incorporate reflective strips or materials that catch sunlight and moonlight, making them highly noticeable at all times.

• Movement: Certain types of diverters are designed to rotate, spin, or flutter in the wind, creating a dynamic visual that captures a bird's attention and prompts it to change its flight path.

By making the conductors more conspicuous, bird diverters provide birds with enough warning to avoid a collision, thus protecting both the wildlife and the reliability of the power grid.
