BirdMark
BM-AG 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 BM-AG (After Glow) diverters are designed to prevent collisions between birds and hard-to-see power lines day or night.

Easy to See
The BirdMark BM-AG 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 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 BM-AG glows up to 10 hours after the sun has set, providing extended protection for at risk birds.
Easy to Install
The BirdMark BM-AG can be installed and removed from the ground without interrupting power. Our patented SnapFast KL-70 clamping jaws securely grip all cables up to a diameter of 2½" (70mm). Once in position, the grip is such that the BirdMark BM-AG stays in position, even in a Force 8 gale.
