RAPTORS. If turbine sites are situated away from problem topography (within 500m of ridges or cliffs) and areas of high raptor concentrations, and in addition have tubular towers and slower blade speeds, this should reduce the number of impacts (Anderson et al.2000). It may be possible to alter habitat conditions within 50 m of wind turbines in order to reduce prey vulnerability to raptor predation near wind turbines, thereby reducing raptor use of these areas as well as mortality. Habitat alterations other than the use of rodenticides remain untested. However, the U.S. Fish and Wildlife Service expressed some skepticism that such localized habitat alterations would shift raptor foraging from near the vicinity of wind turbines to farther away, and the Service might be correct. Still, it might be worth studying cattle exclusion around some select wind turbines, allowing the grass to grow tall, and encouraging fossorial animals at locations farther from the wind turbines (Smallwood et al 2004). In addition, avoid placing external ladders and platforms on tubular towers to minimize perching and nesting. Avoid use of guy wires for turbine or meteorological tower supports. All existing guy wires should be marked with recommended bird deterrent devices (Avian Power Line Interaction Committee 1994, the US fish and wildlife service 2003).
