The FAA and the FCC recognize this concern, and have implemented steps to reduce bird collisions through modifications in red tower lighting. Birds are much less attracted to flashing lights on towers, such as L-864 (red) or L-865 (white) obstruction lights. This puts the birds at greater risk of collision with guy wires, tower structural members, and antennas that are hard to see in dim light. Non-flashing red lights, such as L-810 side-marker lights, can attract birds when illuminated. Why Do FM Frequencies End in an Odd Decimal?.Why AM Radio Stations Make Changes at Night.
