Scientists have known for years that bats navigate by sonar. Like destroyers hunting down a submarine, they send out pulses of sound and steer by the echoes that bounce back from obstacles or prey. In ...

In dark skies around the world there unfolds a nightly battle between bats and the nocturnal insects upon which they feast. You’d have thought bats, equipped as they are with echolocation — in which ...

Unlike most animals that rely on visual senses, bats navigate and locate prey or obstacles through echolocation. By emitting sounds and comparing them to the reflected echoes, bats can "visualize" ...

The call that comes back as a map A bat leaving its roost at dusk emits ultrasound pulses at frequencies between 20 and 200 ...

In order to determine where things are in a space, bats use sonar -- they produce sound waves that hit objects and are reflected back to the bat. Bats can estimate the position of the object based on ...

Dolphins do it. Big brown bats do it. And sometime soon, the Office of Naval Research hopes its researchers will be able to do it too. Echolocation, that is, and turning the processing of such signals ...

Using sound to hunt for food is a pretty ingenious adaptation for bats flying at night. But it doesn’t work if another bat is messing with you. Scientists have discovered that a species of bats can ...

Bats are some of the most highly specialized mammals to have ever evolved. This includes not only the evolution of active flight, but also their echolocation. This ability requires the bats to produce ...

Tiger beetles generate "anti bat-sonar" to prevent echolocating bats from eating them, scientists say. An experiment suggests the beetles mimic sounds created by poisonous insects that bats avoid.
