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.

Species-specific acoustic responses by bats to ultrasonic stimuli used for reducing bat-wind turbine interactions [PDF]
PeerJAn unintended consequence of wind energy generation is bat fatalities caused by wind turbine blade strikes. One potential approach to reduce collision risk is to use ultrasound to create an uncomfortable or disorienting airspace around wind turbine ...

Rainfall and Temperature Explain Colony Variation in Echolocation Calls of the Intermediate Horseshoe Bats (Rhinolophus affinis) [PDF]
Ecology and EvolutionGeographic variation in acoustic signals of animals is shaped by both environmental conditions and morphology related to vocal production. However, the drivers of call variation among colonies at a landscape scale remain largely uncertain.

Energy Expenditure Optimization in the Echolocation of Rhinolophus nippon: Evidence from Heart Rate Stability [PDF]
BiologyAcoustic behavior, essential for communication and perception, is metabolically demanding. Studying the energy costs of echolocation helps us to understand animal energy allocation and provides key insights into the evolutionary constraints of acoustic ...

Human-Machine Cooperative Echolocation Using Ultrasound
IEEE Access, 2022 Echolocation has been shown to improve the independence of visually impaired people, and utilizing ultrasound in echolocation offers additional advantages, such as a higher resolution of object sensing and ease of extraction from background sounds ...

High duty cycle to low duty cycle: echolocation behaviour of the hipposiderid bat Coelops frithii. [PDF]
PLoS ONE, 2013 Laryngeally echolocating bats avoid self-deafening (forward masking) by separating pulse and echo either in time using low duty cycle (LDC) echolocation, or in frequency using high duty cycle (HDC) echolocation. HDC echolocators are specialized to detect

Correlated evolution of wing morphology and echolocation calls in bats
Frontiers in Ecology and Evolution, 2022 IntroductionFlight and echolocation are two crucial behaviors associated with niche expansion in bats. Previous researches have attempted to explain the interspecific divergence in flight morphology and echolocation vocalizations in some bat groups from ...

Different auditory feedback control for echolocation and communication in horseshoe bats. [PDF]
PLoS ONE, 2013 Auditory feedback from the animal's own voice is essential during bat echolocation: to optimize signal detection, bats continuously adjust various call parameters in response to changing echo signals.
