Courtesy of Bat Detective, check out this quick clip in which bats (the high-pitched chirping) join a group of cicadas (the background chatter) to create a pleasant, harmonic chorus.

The bat’s calls are of the “searching” type; at the Bat Detective project, you may also find “social” and “feeding” echolocation calls that you can classify to help scientists monitor bat populations and better understand the environment they inhabit. Join the project today!
