These small Australian animals weigh around 13-17g and can reach speeds of up to 50km per hour. Eastern bentwing-bats use both sight and echolocation to catch small insects mid-air.

In the spring, they return to the same breeding cave, where the female bentwing-bat gives birth to a single young. When the female bats leave to hunt at night, the infant bats are left together in maternity camps.
Weighing in at 13-17g, these tiny nocturnal mammals, also known as Schreibers bentwing-bat, use both sight and echolocation to catch small insects mid-air.
