Significance Animals rely on their senses to survive and reproduce. Sensory systems are subject to a trade-off between the advantage of flexibility that often comes with a cost of a prolonged learning period and the advantage of innateness, which is less successful in dealing with altered environments. Most bat species rely on echolocation—emitting sound signals and analyzing the returning echoes. An object’s distance can be assessed using echolocation given a reference to the speed of sound…

Hearing, echolocation, and beam steering from day 0 in tongue-clicking bats

Rousettus lingual echolocation appears to be a highly functional sensory system from birth and follows a different ontogeny from that of laryngeal bats, possibly owing to tongue-diet maturation effects.

Beyond belongingness: Rethinking innate behavioral predispositions, learning constraints, and cognitive capacities

A number of notions from different research fields outside the hard core of associative learning are presented to understand behavioral variation in a wide array of phenomena, thus, bringing a more informed approach to the nature versus nurture debate.

Adaptive learning and recall of motor-sensory sequences in adult echolocating bats

It is shown that over a period of weeks, Pipistrellus kuhlii bats gradually adapt their pre-takeoff echolocation sequence when moved to a constantly cluttered environment, and after adopting this improved strategy, the bats retained an ability to instantaneously use it when placed back in a similarly clutter environment, even after spending many months in a significantly less cluttered environments.



Auditory cortex of newborn bats is prewired for echolocation

It is demonstrated that in the first postnatal week, before onset of echolocation and flight, dorsal auditory cortex already contains functional circuits that calculate distance from the temporal separation of a simulated pulse and echo.

Echolocating bats can use acoustic landmarks for spatial orientation

The behavioral data show for the first time that the echolocating bat can learn to rely on an acoustic landmark to guide spatial orientation in a complex environment with no visual information.

Innate recognition of water bodies in echolocating bats

Bats perceived any extended, echo-acoustically smooth surface to be water, even in the presence of conflicting information from other sensory modalities, providing the first evidence for innate recognition of a habitat cue in a mammal.

Active Listening for Spatial Orientation in a Complex Auditory Scene

Adaptive temporal control of vocal–motor behavior in an echolocating bat, Eptesicus fuscus, as it captured tethered insects close to background vegetation is reported on.

Although the bat's nervous system follows the general mammalian plan in both its structure and function, it has undergone a number of modifications associated with flight and echolocation, and certain pathways, mainly those having to do with accurate processing of temporal information and auditory control of motor activity, are hypertrophied and/or organized somewhat differently from those same pathways in nonecholocating species.

Bats coordinate sonar and flight behavior as they forage in open and cluttered environments

This study examined the relationship between active sonar sampling and flight motor output as bats changed environments from open space to an artificial forest in a laboratory flight room and reconstructed and analyzed 3D flight trajectories, sonar beam aim and acoustic sonar emission patterns as the bats captured prey.

Breaking the trade-off: rainforest bats maximize bandwidth and repetition rate of echolocation calls as they approach prey

Southeast Asian rainforest bats (in the vespertilionid subfamilies Kerivoulinae and Murininae) are able to maintain high call bandwidths at very high repetition rates throughout approach to prey, suggesting that the extreme vocal performance of these bats evolved as an adaptation to echolocating and tracking arthropods in the dense rainforest understorey.

Comparisons between discrimination performance and autocorrelation functions of echolocation sounds used in the discriminations suggest that these bats possess some neural equivalent of a matched‐filter, ideal sonar receiver which functionally cross‐correlates a replica of the outgoing signal with the returning echo to detect the echo and determine its arrival time.
