Towerkill

Guy wires pose a fatal threat to birds, which often circle the tower lights at night.

Towerkill is a phenomenon in which birds are killed by collisions with antenna towers. In poor visibility conditions, birds may simply fly into towers' guy-wires. Night illuminations around the towers can also disrupt migration patterns, with disoriented birds colliding with the structure. Research indicates that blinking lights can reduce deaths without diminishing visibility by aircraft.
