Bats navigate their environment using echolocation. They produce sound waves that are above the human hearing to catch their prey, according to the National Park Service. These sound waves are called ultrasound that bounces off objects in the environment.
Then the sound returns to the bats ears which are now finely tuned to recognize their own calls. Scientists can translate these sounds into forms that human ears could hear and see.
But recently, a new study from the researchers of Tel Aviv University in Israel discovered that bats, unlike birds and other animals, are born with the knowledge of echolocation. On the other hand, other animals learn echolocation as they grow.
