Power Line Markers, Bird Diverters, and FAA Obstruction Lights

BirdMark®
Bird Diverter

Birds large and small—including swans, eagles, hawks, ducks, geese, and many others—often cannot see power lines near the horizon, and they lack the maneuverability to avoid them when they get close enough to see them. Over one million birds are killed annually in North America! BirdMark (After Glow) bird diverters are designed to prevent collisions between birds and hard-to-see power lines day or night.

Easy to See

The BirdMark bird diverter offers a low cost, permanent solution for helping endangered species avoid power lines in traditional flight paths. BirdMarks stand out like a beacon against background features, letting birds see where the power lines are. When swaying in the wind, BirdMarks also make a noise that birds can hear. Highly reflective orange and yellow tape is positioned in the center of each BirdMark bird diverter to further assist in warning birds.

Night Glow Capability

Other types of bird diverters are usually designed to help birds avoid obstructions during daylight, but recent studies indicate that most bird collisions happen during low light situations such as fog, rain, and the hours before and after dusk. The BirdMark glows up to 10 hours after the sun has set, providing extended protection for at risk birds.

Easy to Install

The BirdMark is easily installed by hot stick on live power lines (115 kV maximum). It’s also safe to use on OPGW lines. Our patented and rugged SnapFast mounting clamp prevents line slippage on single or bundled cables, even in a Force 8 gale. Choose from two sizes of clamp:
10–70 mm (0.39–2.75 in.) P/N #BM-AG-SF10-70
4–16 mm (0.16 to 0.63 in.) P/N #BM-AG-SF6-16
