" The FireFly BFDs devices reflect sunlight during the daylight hours and emit luminescent light during twilight and at night. This sparkling and refraction of light allows the birds to change their flight pattern to divert around the marked wires and avoid collisions. The rotational speed of the Firefly increases its effectiveness. "

“The FireFly is a clearly visible "SCARECROW" diverts the birds, preventing them from colliding with the overhead lines etc.”

"Selection of wire markers that move, incorporate reflective and non-reflective components, and have a glow-in-the-dark component is recommended. The glow-in-the-dark components of the evaluated markers measure reflected light in the UV and near UV spectrum, which appears to be important to avian ecology."

“New types of Bird Flight Diverters (BFDs) deserve special attention, because they are largely in accordance with the technical features mentioned for successful collision mitigation: the FireFly BFDs developed by AB Hammarprodukter from Sweden.”
