Bats

An unprecedented number of bats are being killed by wind turbine blades. A new report has found bats may be mistaking wind turbines for trees.

Bats are often looking for a place to roost when the moon is bright and winds are low. That’s when the conditions can be the deadliest for bats flying near wind turbines.

U.S. Geological Survey researchers used infrared video to track movements at a wind farm. They saw more bats approaching the turbines when the blades were moving slower than when they were moving faster.

You may find bats scary. But one group of nature lovers doesn’t. They recently spent a night out tracking bats in central Washington. They wanted to check-in on how bat populations are doing in the state. EarthFix reporter Courtney Flatt has more.
