From, the Pittsburgh Post-Gazette :- Not content with learning about avian mortality after wind farm installation, a point at which it's basically too late to do much about it, researchers have turned the tables on wind turbine risk, tracking raptor migration routes to map out places that wind turbines should be excluded. We've written at length about the common "eco-myth" about bird kills associated with wind farms. Yet we certainly acknowledge that there are key habitats and passages where turbines do not belong. We think it's great that "The goal of the aviary study is to produce maps that land managers, government regulators and the wind power industry will use to guide wind power development and turbine placement throughout the northeast. Golden eagles were selected for study because they are an "umbrella species," that migrate along routes shared by other raptors."
