Bird collisions with overhead wires have been reported in the United States at least since 1876. A number of solutions have been tried all with varying degrees of success. Raptor silhouettes, different color marker balls, "bird diverters," "flappers" and various other devices to warn birds all work to some degree. However, depending on the target species and the object being marked, if you use the wrong type or color of device it may not be effective, could result in a maintenance problem, or may even cause lines to go down. To date, there is very little published empirical data on which device works for which species or group of species. Anecdotal information suggests that some things do not work as well for some bird species as they do for others. This paper will discuss the mitigative measures found in the literature and provide a brief evaluation of their effectiveness and some of the problems they may create. It will also discuss some of the on-going research, including the effects of motion and light, where information is available. Evaluation of marking devices will be based on existing literature, the experience of line crews and personal experience. [ABSTRACT FROM AUTHOR] |
