Bat Mothers Exhibit Stronger Heart Rate Response to Own Offspring's Calls

Research published in Frontiers in Ethology indicates that mother Japanese house bats show a more pronounced heart rate increase when hearing their own pups' isolation calls compared to those of unfamiliar young. This study offers valuable insights into the physiological basis of maternal recognition and communication in bats, also noting a strong reaction to unfamiliar adult male calls, potentially signaling a perceived threat.
