How is it that bats are able to fly at night without colliding with other objects?
Bats can fly at night without colliding with other objects because they emit high-frequency ultrasonic squeaks while flying and listen to the echoes produced by the reflection of their squeaks from the objects or obstacles in their path. From the time taken by the echo to be heard, bats can judge the distance of the object in their path and avoid it by changing the direction.
