Mark power lines to reduce incidental bird mortality
A controlled before-and-after study in 1997-2000 in northern Colombia (De la Zerda & Roselli 2003) found that the average number of bird deaths due to collision with power lines was significantly lower (5.3 deaths/ha) in a site where the ground wires were marked with yellow plastic spirals than for an unmarked circuit (13.6 deaths/ha); no significant difference in collision mortality between the circuits was detected prior to marking. A total of 810 birds of 47 species were found.
