Bats Adapt Echolocation to Avoid Collisions in Dense Cave Emergence

During the night flight they stay on the right route. Their hearing serves as a compass. But do bats have different sizes of ears? An overview.

To find the cave exit, thousands of bats often roar at the same time. How does an animal still hear its echo to orient themselves? With an amazing trick.

Biology: Bats produce high-frequency sounds to orient themselves. How do they do this when there are many bats nearby that also produce sounds? From…

Bats can move almost without collisions even in dense crowds. Researchers have now found out how to do this.

The echolocation of bats occurs by projecting ultrasonic sounds from the mouth or nose and then detecting the echoes that return from any object within reach. Bats produce these pulses in rapid succession to receive a regularly updated image of their environment. In other words, a single call gives the bat a single snapshot of their environment, while a series of calls provides a series of snapshots, just as a strobe light provides us with a ser…

Scientists solve 'cocktail party' mystery of bat echolocation

Every night, bats emerge out of roosts in massive numbers, creating what scientists have called a 'cocktail party nightmare' of clashing echolocations. Nobody knew how bats managed this severe sensorial challenge. Now, scientists have tracked bats within a group of thousands to find out: when bats first emerge from the roost, they increase their distance from the center of the group and adjust their echolocation to maneuver safely in the areas o…
