The U.S. Geological Survey has developed a new model that it says can help predict and prevent bird fatalities at wind facilities before
they are even built. The model takes into account three parameters, all of which can be measured before construction: the total footprint of the turbines, avian traffic near the facility, and collision probability. The model used golden eagles as a case study because their soaring and hunting behaviors make them susceptible to turbine collisions. Golden eagles also are long-lived and reproduce relatively late in life, which means wind farm fatalities could have particularly severe population impacts. For two years, the model successfully estimated eagle collisions at a newly constructed wind facility in Wyoming, the researchers say. The model’s simplicity “allows wind facility developers to consider ways to reduce bird fatalities without having to collect a complicated set of data,” said Leslie New, a researcher at Washington State University, who led the project.
