Summary:
A new call that some bats use to tell other foraging bats to 'back off' from bugs they've claimed for themselves has been identified by scientists. This sound, called a 'frequency-modulated bout,' warns other bats away from prey. The researchers are first to report this ultrasonic social call produced exclusively by flying, foraging male big brown bats, in a new article.
