In habitats in which multiple species are prey to the same predators, individuals can greatly benefit from recognizing information regarding predators that is provided by other species. [] Key Method We presented alarm calls to free-ranging eastern gray squirrels (Sciurus carolinensis) and recorded behavioral changes in vigilance and antipredatory response.

Eavesdropping grey squirrels infer safety from bird chatter
TLDR
It is suggested that eastern gray squirrels eavesdrop on non-alarm auditory cues as indicators of safety and adjust their vigilance level in accordance with the vigilance level of other species that share the same predators.
Does similarity in call structure or foraging ecology explain interspecific information transfer in wild Myotis bats?
TLDR
The results confirm information transfer across species boundaries and highlight the importance of context on the studied behaviour, but cannot resolve whether information transfer in trawling Myotis is based on acoustic similarity only or on a combination of similarity in acoustics and foraging ecology.
Multiple adaptive and non-adaptive processes determine responsiveness to heterospecific alarm calls in African savannah herbivores
TLDR
It is suggested that mammals can respond adaptively to variation in the information provided by heterospecific callers but within the constraints imposed by a sensory bias towards conspecific calls and reduced learning of less familiar calls.
Prey Responses to Predator's Sounds: A Review and Empirical Study
TLDR
It is found that Mule deer respond to and discriminate among predators based on predator vocalizations and have retained an ability to respond to wolves that have been extinct from the study area since the early 20th century.
Eavesdropping on heterospecific alarm calls: from mechanisms to consequences
TLDR
Overall, it is known that eavesdropping on heterospecific alarm calls is an important source of information for many species across the globe, and there are ample opportunities for research on mechanisms, fitness consequences and implications for community function and signalling evolution.
Divergence in mating signals correlates with genetic distance and behavioural responses to playback
TLDR
It is demonstrated that the most distantly related species have the most divergent songs; that male wrens perceive divergence in fine structural characteristics of songs; and that perceptual differences between species reflect evolutionary history.
Sexual and non-sexual social preferences in male and female white-eyed bulbuls
TLDR
The results suggest that ornamentation and familiarity are important features, playing different roles in males and females, in both social and sexual selection processes.
Predation risk modulates diet‐induced obesity in male C57BL/6 mice
TLDR
Whether the risk of being predated modulates the body weight gain is assessed, providing an ecological context for the obesity resistance observed in many species of small mammals.

Red squirrels (Sciurus vulgaris) respond to alarm calls of Eurasian jays (Garrulus glandarius)
TLDR
Results suggest that red squirrels recognize heterospecific alarm vocalizations of jays and discriminate them from equally loud non-threatening sounds.

TLDR
Results indicate that both marmots and squirrels recognized not only their own species' anti-predator vocalizations, but also the alarm calls of another species, and that these vocalizations were discriminated from an equally loud non-threatening sound.
Mule deer (Odocoileus hemionus) respond to yellow‐bellied marmot (Marmota flaviventris) alarm calls
TLDR
The results suggest relative size differences do not prevent interspecific communication and that common predators should generally drive the evolution of the ability to learn to respond to meaningful risk cues.
Eavesdropping of woodchucks (Marmota monax) and eastern chipmunks (Tamias striatus) on heterospecific alarm calls
TLDR
E eavesdropping on heterospecific alarm calls by nonsocial eastern chipmunks and woodchucks is examined to suggest that nonsocial mammals might benefit from eavesdropper behaviors similar to those displayed upon hearing a conspecific's alarm call.
Response to conspecific and heterospecific alarm calls in mixed-species bird flocks of a Sri Lankan rainforest
TLDR
The response of birds to conspecific and heterospecific calls in a mixed-species flock system of a Sri Lankan rainforest is investigated, concluding that birds are listening to heterOSpecifics and suggesting that their response is influenced by several factors, including their foraging technique.
A mutual understanding? Interspecific responses by birds to each other's aerial alarm calls
TLDR
The results demonstrate, after at least 50 years of interest in the subject, that there can be mutual responses to aerial alarm calls between species.
Recognition of heterospecific alarm vocalizations by bonnet macaques (Macaca radiata).
TLDR
Age and experience are important factors in heterospecific call recognition by bonnet macaques and call recognition was highest in adults and in regions where individuals were frequently exposed to the calling species.
An avian eavesdropping network: alarm signal reliability and heterospecific response
TLDR
There can be mutual responses to alarm calls between ecologically distinct species, that responses can be symmetrical or asymmetrical between species, and that call reliability appears to affect response.
Eavesdropping on the Neighbourhood: Collared Pika (Ochotona collaris) Responses to Playback Calls of Conspecifics and Heterospecifics
TLDR
The acoustic environment, composed in part by the vocalizations of sympatric animals, is a major source of information and can be used to fine-tune behavioural decisions and the ability to make use of information from different sources in their acoustic environment likely facilitates pikas’ behavioural decisions that affect foraging, predator avoidance and nepotism.
