Wolfe Island, ON, Jul 07, 2010 — A recent study of bird and bat mortality at Wolfe Island's 82-turbine wind farm is raising concerns among environmentalists. Wolfe Island is Canadian territory, located where Lake Ontario empties into the St. Lawrence River. The report found 600 birds and more than a thousand bats were killed by the windmill blades in a six month period. Nature Canada called the numbers "shockingly high." Ornithologist Bill Evans says the real question is which species of birds died. Evans directs Old Bird, Inc. in Ithaca and has consulted for both wind power companies and environmental groups. He told David Sommerstein Wolfe Island is a designated important bird area, so ornithologists predicted high fatalities. Evans says the number of hawks, owls, and other raptors was the most alarming.
