Researchers have developed an interactive tool that uses bat calls and local environmental conditions to help wind farms reduce bat fatalities while still running efficiently.
...Using devices to detect bats' echolocation calls, the researchers linked the presence of bats to weather conditions measured on-site. The results showed that multiple echolocation detectors were required to accurately characterize bat activity.
The study also showed that echolocation detectors placed at 72 feet and 170 feet (22 meters and 52 meters) above ground were more effective at characterizing migratory bat activity than those closer to the ground. The researchers used these findings to help build the interactive tool, which can be found on the PSW website.
