Michigan’s nine species of bats are all insectivores and they’re nocturnal, so the best time to look and listen for bats is a warm summer night after dark! Luckily, our recording equipment allows us to locate bats even when we can’t see them. Plug your acoustic monitoring device into your phone or iPad. After downloading the free Echometer app, plug your acoustic monitoring device into your phone or iPad. Find a place that forms a corridor (a trail, a pond or other open space near a wooded area) where bats are likely to be capturing insects in flight. Turn on the record function of the app, and watch and listen as it displays the sounds it records. Bats will be identified by their unique calls! Compare different times of evening or different months- do you find the same species of bats or do they change?
