The numbers of bats killed at FPL Energy's Mountaineer Wind Farm on Backbone Mountain in West Virginia (Windpower Monthly, October 2003) continued to rise through September and October. At least 400 bats have died at the site since August. The deaths are a mystery to scientists. FPL's Steve Stengel says that no threatened or endangered animal has yet been identified among the carcasses. FPL's principle environmental specialist, Jim Lindsay, says the cause of the deaths has not yet been established. "This is unfolding before our very eyes," he said. "It's on-going work. It's something that we are following very closely and we'll get to the bottom of all these questions." The company says it intends to discuss the growing problem of bat kills at the November meeting of the National Wind Coordinating Committee in Washington DC. It also states it is "entertaining project-specific studies at Mountaineer."
