Why do bats fly in groups?

6 min read

Asked by: Janelle Bennett

Bats detect their neighbors better in less-aligned groups compared to more aligned groups. During aligned emergence flight, the focal bat always receives loud frontally directed masking calls from bats behind it, in addition to the relatively loud side-calls emitted by neighbors to its left and right.

Why are bats in groups?

When bats live in large colonies, they’re able to reproduce more efficiently, stay warmer during hibernation, and fend for themselves better against predators. There is, after all, safety in numbers.

Bat groups also show coordinated behaviors in cave flights, evening emergences and mating swarms (5, 6).

What are bats afraid of?
