  I found there was a bat nest in my balcony recently, and one night I happened to see they flew across the patio under our apartment and hover in the sky. I was shocked, because it was dark outside but they knew exactly where to go without mistakes. Moreover, they went out only at night.

  I thought bats are interesting not because they can fly in the dark since I know they are nocturnal animals. I always think the ability which aids bats fly and prey capture is their unusual eye-sight, like another nocturnal animal, owls. But the truth is because of their echolocation. Bat echolocation is a perceptual system where ultrasonic sounds are emitted specifically to produce echoes. By comparing the outgoing pulse with the returning echoes the brain and auditory nervous system can produce detailed images of the bat's surroundings. This allows bats to detect, localize and even classify their prey in complete darkness.
