Unmatched in visibility and efficiency of installation, this uniquely effective design is the durable, secure solution for long term avian protection
For maximum contrast and maximum protection, the Hawk Eye Bird Flight Diverter delivers 360-degree, 24-hour visibility
Among all the line markers in the industry, Power Line Sentry’s Hawk Eye™ Bird Flight Diverters stand out with the largest surface area of reflective and glow-in-the-dark materials, as well as superior contrast. These features make Hawk Eye™ markers highly visible in low-light conditions -critical for preventing avian collisions, as many birds are at risk during dawn, dusk, fog, and other low-visibility weather conditions.
Each Hawk Eye™ Bird Flight Diverter is equipped with a 24-hour glow-in-the-dark band, highly reflective prismatic yellow bands, and a distinctive tent-like shape. Together, these elements ensure maximum visibility from all angles and in challenging light environments.
Designed in collaboration with an ornithologist optometrist, this innovative product aligns with APLIC’s research, which highlights the importance of contrast in low-light conditions for alerting birds to hard-to-see objects.
With Hawk Eye™, you’re choosing a proven solution to enhance bird safety and protect wildlife.
