Over 70% of the droppings of the gleaning bat Otonycteris hemprichii can contain scorpion fragments. [...] Key Method We confirmed that O. hemprichi is a whispering bat (approx. 80 dB peSPL) with short, multi-harmonic calls. In a flight room we also confirmed that O. hemprichii detects scorpions by their walking noises. Amplitudes of such noises were measured and they reach the flying bat at or below the level of echoes of the loess substrate. Bats dropped straight onto moving scorpions and were stung…Expand
A whispering bat that screams: bimodal switch of foraging guild from gleaning to aerial hawking in the desert long-eared bat
TLDR
It is concluded that the desert long-eared bat switched from passive gleaning to capturing airborne insects (aerial hawking), a full bimodal switch between foraging guilds with the respective changes in source level to those typical of a true aerial hawker.
A Sting in the Night: Pallid Bat Detection of Dangerous Prey
TLDR
It is predicted that under moonlit conditions, pallid bats would plan attacks on scorpion prey, therefore, being stung less often, and the role of bat vision in predator-prey interactions between a similar bat species and northern scorpions is examined.
Venom-spraying behavior of the scorpion Parabuthus transvaalicus (Arachnida: Buthidae)
TLDR
The results suggest that venom spraying might be useful as an antipredator function and can be modulated based on threat.
Ultrasound avoidance by flying antlions (Myrmeleontidae)
TLDR
It is argued that the high response threshold for low-frequency ultrasound is adaptive for an insect that is mainly active close to and within vegetation, because a behavioural response to the lower ultrasonic frequencies used by high-flying bats would result in evasive action in the absence of actual predation risk.
Arizona bark scorpion venom resistance in the pallid bat, Antrozous pallidus
TLDR
It is shown with behavioral measures and direct injection of venom that the pallid bat is resistant to venom of the Arizona bark scorpion, Centruroides sculpturatus, and altered sodium ion channel function may partly underlie such resistance.
Roost selection by female Hemprich's long-eared bats
TLDR
In contrast to bats that live in temperate habitats, O. hemprichii do not need to seek roosts with temperature conditions specific to the periods of pregnancy or lactation because natural changes in Tr suffice, and other factors are involved in the decision to choose a roost or to abandon it.
Threat level influences the use of venom in a scorpion species, Tityus stigmurus (Scorpiones, Buthidae)
TLDR
The results suggest that T. stigmurus reacts differently depending on the stimulus level, supporting the assumption that milky venom is only used when the animal is highly stressed because this venom represents higher metabolic costs than the production of clear venom.
Defensive stinging by Parabuthus transvaalicus scorpions: risk assessment and venom metering
TLDR
These scorpions perceive risk and regulate venom expenditure during stinging according to level of threat, providing further support for the venom-metering hypothesis.
How to attack a scorpion: venom metering during a repeated attack
TLDR
It is concluded that a repeated attack seems an effective strategy for scorpion predators to reduce the defensive investment of scorpions.
The sensory ecology of prey detection in the bat-eared fox (Otocyon megalotis)
TLDR
This study provides empirical confirmation for anecdotal reports that the bat-eared fox is predominantly reliant on auditory cues to determine hunting success by conducting sensory trials with individuals belonging to a habituated population in the Kuruman River Reserve in South Africa.

Natterer’s bat (Myotis nattereri Kuhl, 1818) hawks for prey close to vegetation using echolocation signals of very broad bandwidth
TLDR
Myotis nattereri (Vespertilionidae, Chiroptera) is able to perceive prey by echolocation within a few centimeters of echo-cluttering vegetation, by using frequency-modulated search signals of very large bandwidth (up to 135 kHz).
Behavioral and ecological aspects of gleaning by a desert insectivorous bat Antrozous pallidus (Chiroptera: Vespertilionidae)
  • G. Bell
  • Biology
    Behavioral Ecology and Sociobiology
  • 2004
TLDR
It is concluded that A. pallidus use echolocation, and perhaps vision, to assess habitat and avoid obstacles, but locate prey by listening to their sounds, and is able to discriminate between sounds which probably indicate food from sounds which offer no reward.
Feeding Habits of the Long-Eared Desert Bat, Otonycteris hemprichi (Chiroptera: Vespertilionidae)
TLDR
Visual nocturnal observations confirmed that this species captures its prey from the surface of the ground.
Prey preferences of the leopard (Panthera pardus)
TLDR
This model will allow us to predict the diet of leopards in areas where dietary information is lacking, also providing information to assist wildlife managers and conservation bodies on predator carrying capacity and predator– prey interactions.
Echolocation by Insect-Eating Bats
TLDR
This article describes the echolocation behavior of insect-eating bats and shows how differing circumstances such as habitat type, foraging mode, and diet favor different signal types, and outlines the perceptual tasks that must be performed by foraging bats.
Echolocation and passive listening by foraging mouse-eared bats Myotis myotis and M. blythii
TLDR
It is suggested that the buzz, absent in M. blythii at least when gleaning from the same substrate, is used to assess the distance from ground and refine the landing manoeuvre, and support a role for echolocation during passive listening and suggest a functional role for buzzes in landing control.
Cues for acoustic detection of prey: insect rustling sounds and the influence of walking substrate
TLDR
The data show that rustling sound amplitude and frequency content depend on substrate type, and provides for the first time estimates of realistic detection distances in the field, which range from below 1 m to over 13 m, depending on the substrate, insect mass, walking speed and background noise level.
The role of echolocation in the hunting of terrestrial prey – new evidence for an underestimated strategy in the gleaning bat, Megaderma lyra
TLDR
It is shown that the gleaning bat, Megaderma lyra, is able to find silent and motionless prey on the ground, and prey-dependent shifts in sonar activity, the broadband call structure with an emphasis on higher harmonics, and a systematic shift of the calls' peak frequencies during hovering are discussed as adaptations to identifying prey by sonar.
Predation risk and state-dependent foraging in scorpions: effects of moonlight on foraging in the scorpion Buthus occitanus
TLDR
The influence of moonlight on the foraging behaviour of the scorpionButhus occitanus israelis was observed, and it is suggested that the scorpions use environmental factors such as illumination and humidity as proximal cues, to evaluate levels of predation risk and food availability.
The relationship between sit and wait foraging strategy and dispersal in the desert scorpion, Scorpio maurus palmatus
TLDR
It seems that the S. maurus palmatus biological relationship model can be applied, with modifications, to a wide spectrum of desert burrowing animals and suggest that many other burrowing desert animals may face the problem of unpredictability of biological resources.
