Echolocation in Oilbirds and swiftlets [PDF]

Frontiers in Physiology, 2013
The discovery of ultrasonic bat echolocation prompted a wide search for other animal biosonar systems, which yielded, among few others, two avian groups.

Echolocation by Quasiparticles

, 2009
It is shown that the local density of states (LDOS), measured in an Scanning Tunneling Microscopy (STM) experiment, at a single tip position contains oscillations as a function of Energy, due to quasiparticle interference, which is related to the positions of nearby scatterers.

It’s not black or white - on the range of vision and echolocation in echolocating bats [PDF]

Frontiers in Physiology, 2013
Around 1000 species of bats in the world use echolocation to navigate, orient and detect insect prey. Many of these bats emerge from their roost at dusk and start foraging when there is still light available.

When echolocating bats do not echolocate [PDF]

Communicative & Integrative Biology, 2008
Echolocating bats are known to continuously generate high frequency sonar pulses and listen to the reflecting echoes to localize objects and orient in the environment. However, silent behavior has been reported in a recent paper, which demonstrated that the big brown bat (Eptesicus fuscus) can fly a relative long distant (0.6 to 8 m) without ...

6-hour Training in click-based echolocation changes practice in visual impairment professionals

Frontiers in Rehabilitation Sciences, 2023
Click-based echolocation can support mobility and orientation in people with vision impairments (VI) when used alongside other mobility methods. Only a small number of people with VI use click-based echolocation.

Driving factors for the evolution of species-specific echolocation call design in new world free-tailed bats (molossidae). [PDF]

PLoS ONE, 2014
Phylogeny, ecology, and sensorial constraints are thought to be the most important factors influencing echolocation call design in bats. The Molossidae is a diverse bat family with a majority of species restricted to tropical and subtropical regions ...

Echolocation in humans: an overview [PDF]

WIREs Cognitive Science, 2016
Bats and dolphins are known for their ability to use echolocation. They emit bursts of sounds and listen to the echoes that bounce back to detect the objects in their environment. What is not as well‐known is that some blind people have learned to do the same thing, making mouth clicks, for example, and using the returning echoes from those clicks to ...
