SUMMARY Rousettus aegyptiacus Geoffroy 1810 is a member of the only genus of Megachiropteran bats to use vocal echolocation, but the structure of its brief, click-like signal is poorly described. Although thought to have a simple echolocation system compared to that of Microchiroptera, R. aegyptiacus is capable of good obstacle avoidance using its impulse sonar. The energy content of the signal was at least an order of magnitude smaller than in Microchiropteran bats and dolphins (approximately… Expand
The effect of familiarity on echolocation in the megachiropteran bat Rousettus aegyptiacus
TLDR
It is shown that the echolocating Megachiropteran bat Rousettus aegyptiacus has a reduced rate of eCholocation signal production in a familiar environment with no obstacle present, which suggests that probe the environment for maximum information is more important for this species than minimizing any cost of probing the environment in a cluttered space.

Echolocation signals and pinnae movement in the fruitbat Rousettus aegyptiacus
TLDR
It is demonstrated that the ears have a greater sensitivity to click stimuli in front of the animal when directed forwards than when back and to the side, and the potential significance of the production of echolocation signals whilst the ears are moving from their least sensitive to their most sensitive position is discussed. Expand
Click-based echolocation in bats: not so primitive after all
TLDR
It is suggested that click-based echolocation in bats should be regarded as a viable eCholocation strategy, which is in fact similar to the biosonar used by most e cholocating animals, including whales and dolphins. Expand
Sonar Signals of Bats and Toothed Whales
This chapter reviews echolocation signals of bats and toothed whales. It addresses mechanisms of sound production and reception, signal structure, patterns of call production, and the role ofExpand
Эхолокация рукокрылых (Chiroptera Blumenbach, 1779) как элемент их экологической пластичности
Aim . The aim of this work was to briefly summarize the current understanding of the phenomenon of echolocation in the order of bats (Chiroptera Blumenbach, 1779). Discussion . The paper discusses:Expand
Presence of single as well as double clicks in the echolocation signals of a fruit bat, Rousettus leschenaulti (Chiroptera : Pteropodidae)
TLDR
The use of simple, brief impulsive clicks and the reduction of interpulse interval and duration, when approaching the sides of the walls suggest that the echolocating fruit bat Rousettus leschenaulti have a good capability of obstacle avoidance as similar to microchiropteran bats. Expand
Sensory systems and spatial memory in the fruit bat Rousettus aegyptiacus
TLDR
A decrease in initial performance when the task was repeated in the dark suggested the possibility that a memory of a location learned using vision does not generalize to echolocation, which suggests a place is remembered as a location in space and not by associations with landmarks in the vicinity.

Vocalizations in the Malagasy Cave-Dwelling Fruit Bat, Eidolon dupreanum: Possible Evidence of Incipient Echolocation?
TLDR
The vocalizations of the Malagasy endemic fruit bat, Eidolon dupreanum, suggest that the social calls 1 and 2 were employed for social communication, whilst echo clicks may have been used in a sensory context, potentially as incipient echolocation to navigate in the dark cave. Expand
Bats are unusually insensitive to brief low-frequency tones
TLDR
All four species of bats were remarkably less sensitive than non-bats to brief sounds of 10 kHz and below, implying that temporal summation in the mammalian auditory system can show large species differences, and that the detection of brief sound is likely influenced by the selective pressures on each species. Expand
Production of Biosonar Signals: Structure and Form
Even though they live in quite different habitats, many bats, a few birds, and a number of marine mammals, including dolphins, rely on biosonar for navigation and foraging for food. Despite the factExpand

Hearing in a megachiropteran fruit bat (Rousettus aegyptiacus).
TLDR
Methodological issues, specifically training an animal to listen for low-intensity signals and imposing a significant cost for failing to report signals (i.e., misses), are discussed as the basis for the discrepancy between results and earlier reports. Expand
Echolocation: Implications for Ecology and Evolution of Bats
  • M. Fenton
  • Biology
  • The Quarterly Review of Biology

TLDR
Echolocation divulges a great deal of information about the echolocator itself, and so permits intraspecific and interspecific piracy of information, a consequence that could be inconvenient or fatal in animals that use it. Expand

TLDR
An array of four hydrophones arranged in a symmetrical star configuration was used to measure the echolocation signals of the Atlantic spotted dolphin in the Bahamas and the characteristics of the signals were similar to those of captive Tursiops truncatus, Delphinapterus leucas and Pseudorca crassidens measured in open waters under controlled conditions.

Echolocation in free-flying Atiu Swiftlets (Aerodramus sawtelli)
TLDR
Spectral analyses indicate that the birds do not adjust the peak frequencies of their calls as they fly within the cave and it is suggested the bird does not systematically structure the frequency content of its calls. Expand
The physiology of vocalization by the echolocating oilbird,Steatornis caripensis
Summary1.Oilbirds (Steatornis caripensis; Steatornithidae) have a bilaterally asymmetrical bronchial syrinx (Fig. 2) with which they produce echolocating clicks and a variety of social vocalizations.Expand
Echolocation behavior of big brown bats, Eptesicus fuscus, in the field and the laboratory.
TLDR
Echolocation signals were recorded from big brown bats, Eptesicus fuscus, flying in the field and the laboratory, and in the terminal phase of insect capture sequences, where Fmin decreased with decreasing signal duration. Expand
THE SENSITIVITY OF ECHOLOCATION IN THE FRUIT BAT, ROUSETTUS
TLDR
Rousettus' success at echolocation was considerably reduced when it was forced to fly in a field of intense thermal noise and its results have been compared with those of Curtis (1952) who studied the vespertilionid, Myotis l. Expand
Hearing in American leaf-nosed bats. III: Artibeus jamaicensis
TLDR
The audiogram of the Jamaican fruit-eating bat (Phyllostomidae: Artibeus jamaicensis) is determined, suggesting that the evolution of echolocation may have been accompanied by the extension of their high-frequency hearing by an average of one-half octave. Expand
Temporal integration in the echolocating bat, Megaderma lyra
TLDR
The psychophysical temporal integration of acoustic intensity in the echolocating bat Megaderma lyra is measured using a two-alternative forced-choice procedure in which the absolute threshold for pairs of short tone pips was determined as a function of the temporal separation between the pips.
