“…But are animals able to respond adaptively to these differences in the information provided by heterospecific alarm calling? Some studies have indeed found alarm responses to depend on predator overlap [11,12], call reliability and caller consistency [13][14][15][16]. Still, other studies indicate that responses are also influenced by the similarity of the acoustic structure to the conspecific alarms [17,18], suggesting that sensory bias limits the ability to extract information from heterospecific alarm calls.…”

Heterospecific alarm calls may provide crucial survival benefits shaping animal behaviour. Multispecies studies can disentangle the relative importance of the various processes determining these benefits, but previous studies have included too few species for alternative hypotheses to be tested quantitatively in a comprehensive analysis. In a community-wide study of African savannah herbivores, we here, for the first time to our knowledge, partition alarm responses according to distinct aspects of the signaller–receiver relationship and thereby uncover the impact of several concurrent adaptive and non-adaptive processes. Stronger responses were found to callers who were vulnerable to similar predators and who were more consistent in denoting the presence of predators of the receiver. Moreover, alarm calls resembling those of conspecifics elicited stronger responses, pointing to sensory constraints, and increased responsiveness to more abundant callers indicated a role of learning. Finally, responses were stronger in risky environments. Our findings suggest 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. The study thereby provides new insights central to understanding the ecological consequences of interspecific communication networks in natural communities.

“…Certainly, many heterospecifics do listen to the information in mobbing calls (Carlson, Greene, et al, 2020;Carlson, Healy, et al, 2020;Coppinger et al, 2020;Ito & Mori, 2010;Munoz, Brandstetter, Esgro, Greene, & Blumstein, 2015;Templeton & Greene, 2007) and these calls may facilitate the formation of many mixed-species-flocks (Goodale, Beauchamp, Magrath, Nieh, & Ruxton, 2010;Goodale & Kotagama, 2008;Sridhar, Beauchamp, & Shanker, 2009;Sridhar, Jordán, & Shanker, 2013).…”

“…shows that individuals may be communicating to other heterospecific prey (Goodale & Kotagama, 2006), the same functional response may occur when others simply listen to this broadcast signal, regardless of the intended recipient . There is evidence, however, that many heterospecifics do listen to the information in mobbing calls (Carlson, Greene, et al, 2020;Carlson, Healy, et al, 2020;Coppinger et al, 2020;Ito & Mori, 2010;Munoz, Brandstetter, Esgro, Greene, & Blumstein, 2015;Templeton & Greene, 2007) and these calls may be a driving factor in the formation of many mixed-species-flocks (Goodale, Beauchamp, Magrath, Nieh, & Ruxton, 2010;Goodale & Kotagama, 2008;Sridhar, Beauchamp, & Shanker, 2009;Sridhar, Jordán, & Shanker, 2013).…”

Mobbing is an important anti-predator behavior where prey harass and attack a predator to lower the immediate and long-term risk posed by predators, warn others, and communicate about the predator’s threat. While this behavior has been of interest to humans since antiquity, and aspects of it have been well researched for the past 50 years, we still know little about its ecology and the evolutionary pressures that gave rise to this ubiquitous anti- predator behavior. In this review, we explore what mobbing is, how it is used, what its functions are thought to be, its use as a proxy for cognition, before providing suggestions for specific future avenues of research necessary to improve our understanding of mobbing in its ecological and evolutionary context.
