Latest Echolocation Stories
New research reveals that traditionally "non-echolocating" bat species actually use a rudimentary form of echolocation, but not from sounds emitted from their mouth or nose.
There are a lot of insects about, but in some parts of the world there are a lot of bats too, and with competitors sometimes numbering over a million, Mexican free-tailed bats resort to dirty tactics to gain an advantage in the hunt for food.
Decades of research on how bats use echolocation to keep a focus on their targets not only lends support to a long debated neuroscience hypothesis about vision but also could lead to smarter sonar and radar technologies.
More than 1,000 species of echolocating bats exist, compared to just 80 species of nocturnal non-echolocating birds. It seems that normal vision works in tandem with echolocation to give bats an evolutionary edge, however, no one knows exactly how.
New research shows the Pallas long-tongued bat is a very stealthy predator when it comes to catching insects. This goes against the earlier belief the bat eats insects when they pass by.
Humans can learn to use echolocation to navigate and to find objects, according to new research appearing in the latest edition of the biology journal Proceedings of the Royal Society B.
"Hawkmoths have evolved different ways of avoiding bats - I can’t even explain how amazing this system is, it is just fascinating," said one researcher.
A new study led by the University of Southampton, however, now shows that they have the potential to use echolocation, similar to that of bats and dolphins, to determine the location of an object.
A new study reveals that the way fruit bats use biosonar to 'see' their surroundings is significantly more advanced than first thought.
Batsâ€™ remarkable ability to â€˜seeâ€™ in the dark uses the echoes from their own calls to decipher the shape of their dark surroundings.
