When it isn’t building muscle cars, Chevrolet spends its spare time saving bats. That’s right, the furry animals that fly around at night. Chevrolet has assembled more than 700 bat and bird nesting boxes since 2015 using recycled lithium-ion batteries and spare parts from the Volt. More than 40 wildlife habitat sites across the U.S. and Canada have Chevrolet-built bird and bat houses. Amateur bat enthusiasts, though, won’t be able to purchase Chevy-branded bat houses at their local hardware store.
