Bats can understand the emotional calls from others

12-15-2013 20:22

A recent study in Frontiers of Zoology indicates that bats can understand the emotional calls from other bats. Kastein and colleagues observed the response of the greater false vampire bats to two kinds of calls: one is "aggression calls" which is typically made by a bat to defend its space on a perch from an approaching bat, another is "appeasement calls" which is made by a bat approaching one already ensconced on a perch in order to seek a shared space. They found that the aggression call always drew a bat to fly toward the speaker, while the appeasement calls cause few response from bats. This study indicated that the emotional interpretation might exist widely in mammals.
