Abstract
USGS scientists at the Fort Collins Science Center developed an active research program to investigate the causes and consequences of bat fatalities at wind turbines. Our specific focus is on (1) determining the geographic origins of killed bats and (2) assessing the potential roles of mating and feeding behaviors in the susceptibility of tree bats to deadly encounters with wind turbines. With expertise and experience studying bat migration and behavior, combined with an existing infrastructure that promotes collaboration between disciplines, the USGS is well-equipped to effectively address the problem of bat mortality at wind power facilities. Only through further research will we make progress toward minimizing the impact of this new form of sustainable energy on our Nation's wildlife.
