How does this help migrating cranes?
BFDs
wrap around overhead electrical power wires and
provide images that birds can see. They help
migrating cranes by making power lines more visible so the birds won't
collide with them.
The Firefly reflective tag that hangs from the power line, is visible in low light conditions, the time when collisions are most common.
Usually both the BFD and the Firefly are used together at different intervals on the power lines. Flying into hard-to-see power lines is a leading cause of death for migrating Whooping cranes. BFDs will help keep the skies safer for cranes.
Bird
flight diverters - These markers increase the
diameter of the power line, making it easier for birds
to see and avoid the lines.
Firefly
bird markers- These markers can be seen by birds in
low light conditions and reflect both natural and ultraviolet
light, allowing birds to adjust their flight path before coming
into contact with the line, thus avoiding a collision.
