Study finds Japanese horseshoe bats match each other's frequency to reduce noise in colonies

Greater Japanese horseshoe bats adjust echolocation calls to match frequencies used by other colony members.

Shared frequency reduces noise from overlapping calls, creating a clearer listening range.

This helps bats detect prey more effectively despite many simultaneous calls in crowded colonies.

The finding was published in the Journal of Comparative Physiology A by Doshisha University researchers.
