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
