Greater Japanese Horseshoe Bats Adapt Echolocation Calls for Clearer Prey Detection in Groups
نظرة سريعة
Researchers from Doshisha University in Japan found that greater Japanese horseshoe bats adjust their echolocation calls to a shared frequency when in colonies, reducing interference and improving prey detection.

Bats use echolocation for navigation and hunting, with some species facing challenges in crowded environments.
Bats rely on echolocation to move through the dark and hunt insects. They send out high-pitched sound waves that bounce off nearby objects and return as echoes which helps them judge where things are. But when many bats send out similar sound waves at the same time, their signals can overlap. It creates noise that could make it harder for a bat to identify the echoes from its own calls. A new study published in the Journal of Comparative Physiology A by researchers from Doshisha University in Japan has found that greater Japanese horseshoe bats have a unique way of dealing with this challenge, Science X reported. These bats gradually adjust their calls so that members of the same colony use almost the same frequency. Researchers say this helps the bats receive clearer echoes and better detect prey while flying together. [...]
