A study by West Inc. and two scientists from the U.S. Geological Survey and Federal Communications Commission, sponsored by the nonprofit American Wind Wildlife Institute, measured the impact of North American wind farms on small passerines, including songbirds. The study found that “all bird fatalities from North American wind turbines range from 214,00 to 368,000 annually,” reports nawindpower.com. By comparison, cell and radio towers cause 6.8 million bird fatalities, and cats cause 1.4 billion to 3.7 billion fatalities. West Inc.’s Wallace Erickson, lead author of the report, said, “…one of the most important scientific contributions from this research is our new understanding of the level of impact on individual songbird and other small passerine species.” Terry Root, senior fellow at the Stanford Woods Institute for the Environment, commented on the study, “With comprehensive measures to further minimize impacts on birds, wind power is a growing solution to some of the more serious threats that birds face, since wind energy emits no greenhouse gases that accelerate climate change.” For more, read the full article.
