Bats Avoid Mid-NIR CRASHES by adjusting their echolocation during flight

Bats fly out of caves in large numbers every night. Even thought they fly in huge numbers they do not collide. Scientists have observed this for years. The ability of bats to navigate without crashing remains an area of ​​study. Many species relacation to sense their surroundings. They emit calls and listen to echoes. When many bats use echolocation at the same time, interference should Occur. Scientists refer to this issue as Jamming. This Raises the question of why bats do not collide when leaveing ​​caves in large groups.

How Bats Navigate Without Collisions

According to a study Published in Proceedings of the National Academy of Sciences, Researchers from Tel Aviv University Examined Greater Mouse-Tailed Bats in Israel’s Hula’La Valley. The study was conducted over two years. Small Tracking Devices Were Placed on Multiple Bats. These trackers recorded their locations and sounds. Some of these devices contained ultrasonic microphones. The mics were there to capture the auditories. Since Bats were tagged outside the cave, data at the opening of the cave was not available. A computational model developed by omer mazar was used to simulate the missing data. This model is recreated the nature sequence of bat emergence.

Findings on echolocation adjustments

As per the Findings, 94 Percent of Echolocations was jammed when exited the Cave. Within five seconds, Jamming decreased significantly. Two behavioral adjustments were noted. First, Bats Moved outward from the dense group while staying in formation. They changed their echolocation strategy. Calls Became Shorter, Weaker, and at a Higher Frequency. Scientists Expected Bats to Avoid Jamming By Dispersing. The change in frequency was unexpected.

Reason Behind Echolocation Changes

Omer Mazar, A Researcher involved in the study, explained This shift. He stated in an interview with pHys.org that bats prioritise detecting the nearest barrier. In this case, the obstacle is another bat. They did this by changing the method of echolocation. They gather precise information about their immediative surroundings. This reduces the risk of collisions
