What Are Bats' Favorite Foods? The Truth Lies in the Poop
Want to know what bats eat? Just remember — what goes in must come out.
That's the principle used by researchers from the University of Bristol in the U.K. and the Biodiversity Institute of Ontario, Canada. The scientists wanted to know which insects top the list of bats' favorite food. So they collected four months' worth of bat poop (also known as guano) from roosts in Southern Ontario. A genetic analysis of insect DNA extracted from the guano reveals that the flying mammals like eating insects from aquatic environments.
