Most of us associate echolocation with bats. These amazing creatures are able to chirp at frequencies beyond the limit of our hearing, and they use the reflected sound to map the world around them. It ...

Many species of bats use echolocation to avoid obstacles like tree branches and hunt small insects as they fly through the dark. But it turns out echolocation for bats is much more than just a ...

The use of reflected sounds to navigate, known as echolocation, is a behaviour most associated with bats, whales and dolphins, but other species also use the sensory technique — including humans. It ...

"Lots of things fly at night," says Harlan Gough, a wildlife biologist with the U.S. Fish and Wildlife Service. Nightfall can set the stage for an acrobatic high-stakes drama in the air — a swirl of ...

Bats are nocturnal hunters and use echolocation to orientate themselves by emitting high-frequency ultrasonic sounds in rapid succession and evaluating the calls’ reflections. Yet, they have retained ...

Echolocation is a technique that uses sound waves to find and detect objects. Some studies suggest that some blind people have developed echolocation to better navigate the world around them. Some ...

Blind as a bat? Hardly. All bats can see to some degree, and certain species possess prominent eyes and a keen sense of vision. Take the Egyptian fruit bat (Rousettus aegyptiacus). This species is ...

High-frequency ultrasound significantly reduces the size of the face and modifies the internal bones of the ear in bats.

Toothed whales use sound to find their way around, detect objects, and catch fish. They can investigate their environment by making clicking sounds, and then decoding the "echoic return signal" ...
