Latest Animal echolocation Stories
(Ivanhoe Newswire) -- Everybody has heard about echolocation in bats and dolphins. These creatures emit bursts of sounds and listen to the echoes that bounce back to detect objects in their environment. What is less well known is that people can echolocate, too. In fact, there are blind people who have learned to make clicks with their mouths and to use the returning echoes from those clicks to sense their surroundings. Some of these people are so adept at echolocation that they can use this...
Echolocation in bats and dolphins is well known. Bursts of sounds are created and the echoes that bounce back are used to locate and detect objects in the environment. What is less well known is that people can echolocate, too.Blind people have been known to learn to make clicks with their mouths and to use the returning echoes from those clicks to sense their surroundings. Some of these people are so adept at echolocation that they can use this skill to go mountain biking, play basketball,...
(Ivanhoe Newswire) --Tired of the old pick up line "In a room full of people all I hear is you?"Â Well, research reveals that may be true. A study found that brains of bats tell some neurons to 'shush' and others to 'yell louder' in order for key sounds to be heard above background noise"”a process that may be working in humans as well."Some neurons seemed to know to yell louder to report communication sounds over the presence of background noise," Bridget Queenan, a doctoral...
GUMC neuroscientists find brains of bats tell some neurons to 'shush' and others to 'yell louder' in order for key sounds to be heard above background noiseHow do you know what to listen to? In the middle of a noisy party, how does a mother suddenly focus on a child's cry, even if it isn't her own?Bridget Queenan, a doctoral candidate in neuroscience at Georgetown University Medical Center is turning to mustached bats to help her solve this puzzle.At the annual meeting of the Society for...
The ordinary squid, Loligo pealii"”best known until now as a kind of floating buffet for just about any fish in the sea"”may be on the verge of becoming a scientific superstar, providing clues about the origin and evolution of the sense of hearing.In a hangar-like research building at the Woods Hole Oceanographic Institution (WHOI), biologist T. Aran Mooney is exploring virtually uncharted waters: Can squid hear? Is their hearing sensitive enough to hear approaching predators? How do...
PRAGUE, Aug. 22 /PRNewswire/ -- (15th International Bat Research Conference) -- Wildlife Acoustics, the leading supplier of acoustic monitoring systems for endangered and threatened wildlife species around the world, announces a new high frequency 384kHz model of the SM2BAT Ultrasonic Recorder. The SM2BAT 384kHz Terrestrial Ultrasonic Package, starting at US$999, is a weatherproof, low-power ultrasonic recorder and microphone capable of continuous unattended monitoring and recording of bat...
Communication across species boundaries by echolocation calls in batsBats can distinguish between the calls of their own and different species with their echolocation calls, report scientists of the Max Planck Institute for Ornithology in Seewiesen. This applies even for species closely related and ecologically similar with overlap of call frequency bands (The American Naturalist online, May 11th 2010).As opposed to bird song or the human voice, echolocation calls are primarily used for...
Bats' remarkable ability to "˜see' in the dark uses the echoes from their own calls to decipher the shape of their dark surroundings. This process, known as echolocation, allows bats to perceive their surroundings in great detail, detecting insect prey or identifying threatening predators, and is a skill that engineers are hoping to replicate.A team of British researchers has worked with six adult Egyptian fruit bats from Tropical World in Leeds to record and recreate their calls. These...
CONCORD, Mass., April 7 /PRNewswire/ -- Wildlife Acoustics, the leading supplier of acoustic monitoring systems for endangered and threatened wildlife species around the world, announces breakthrough technology for monitoring bats. The SM2 Terrestrial Ultrasonic Package starting at US$849 is a weatherproof, low-power two-channel ultrasonic recorder capable of continuous unattended monitoring and recording of bat echolocation calls for long periods of time. Each channel has independent...
Despite the fact that bats are active after sunset, they rely on the sun as their most trusted source of navigation. Researchers from the Max Planck Institute for Ornithology found that the greater mouse-eared bat orients itself with the help of the earth's magnetic field at night and calibrates this compass to the sun's position at sunset (published online in Proceedings of the National Academy of Science, PNAS, March 29th, 2010)Since the 1940s it has been known that bats use echolocation...

The greater horseshoe bat (Rhinolophus ferrumequinum) can be found in Japan, Africa, Europe, China, South Asia, Korea, and Australia. It prefers a habitat in warm regions, with open scrub and trees, human settlements, and bodies of water like ponds. It will also inhabit older orchards, glades within woodlands, and permanent pastures, among other areas. Many of its roosts occur in houses in the northern areas of its range and in caves in the southern areas of its range. These bats travel to...
Mehely’s horseshoe bat (Rhinolophus mehelyi) can be found in areas of the Middle East and Eastern Europe, and has a fragmented range. It lives in caves, with a preference for limestone caves with a nearby body of water. It will sometimes roost with other species of horseshoe bats within these caves. It is a medium sized bat, with pale lips and dense fur. The fur is typically whitish gray in color, with darker fur appearing on the back and lighter fur appearing on the underbelly. As is...
The fringe-lipped bat (Trachops cirrhosis) is the only species within its genus, Trachops. This species, as well as its three subspecies, can be found in southern Brazil and from southern Mexico to Bolivia. It prefers a habitat within moist or tropical forests, with abundant water sources. It chooses roosts in hollow logs and caves, and can be seen roosting with other bat species. The fringe-lipped bat can weigh am average of 1.1 ounces. It is typically brownish red in color, although the...
The greater bulldog bat (Noctilio leporinus), also known as the fisherman bat, is native to Latin America. Its range extends from Mexico to northern Argentina, and includes most of the Caribbean Islands. Despite its large range, its distribution is fragmented due to its preferred habitats with an abundance of water. The greater bulldog bat is threatened by deforestation, water pollution, and changing water levels, but with no immediate danger and a large range, the IUCN has placed it as a...
The Mauritian tomb bat (Taphozous mauritianus) is one of 51 species of sac-winged bats. It is native to Madagascar and central and southern Africa. The range of the Mauritian tomb bat is large, encompassing many areas of Africa and the surrounding islands. It can be found in arid habitats as well as in grassland, tropical, and semi-arid habitats. It prefers habitats within moist savannah habitats, however, with plenty of room to fly and roost. Because of its dry habitat choices, these bats...
