Mark power lines to reduce incidental bird mortality
A before-and-after trial at a wetland site in Essex, England (Frost 2010), installed 500 red, spiral-shaped ‘flight diverters’ (32 cm long, 17.5 cm in diameter) at 5 m intervals along 1.5 km of power lines. In two springs preceding installation (2004 and 2006), 28 mute swans Cygnus olor were killed through collisions with the wires. Following installation, one swan was killed in the springs of 2007 and 2008 combined.
