Bats are beneficial consumers of agricultural insect pests, and migratory species of bats provide free pest-suppression services across ecosystems and international borders. Although the underlying causes of bat fatalities at wind turbines remain unknown, potential clues can be found in the patterns of fatalities. TSH scientists, in collaboration with other U.S. Geological Survey (USGS) science centers as well as…
