“…Consequently, studying free-ranging movement may make a valuable contribution to understanding the sensory perspectives of animals. The development of methods to collect real-time data on infrasound from the perspective of equipped animals ( 39 ) in combination with our infrasound soundscape maps will promote investigation into the effect of infrasound on the behavior of birds and other taxa, giving further insight into the nature of long-range movement in the relatively featureless environment of the ocean.…”

“…We developed microbarom soundscape maps, allowing us to model microbarom sound pressure from the perspective of individual birds at any given location and time ( 20 ). Soundscapes methods were validated using in situ infrasound measurements recorded by bespoke INFRA-EAR biologgers attached to birds in addition to 5 y of continuous infrasound array data measured as Kerguelen Island ( 39 ). Using high-resolution GPS tracks collected from 89 individuals breeding on the sub-Antarctic island of Crozet, in the Southern Ocean, we constructed habitat selection models to test whether individuals showed directional preference according to the sound pressure they experienced while in flight, after controlling for contemporaneous wind conditions experienced by birds.…”

The ways in which seabirds navigate over very large spatial scales remain poorly understood. While olfactory and visual information can provide guidance over short distances, their range is often limited to 100s km, far below the navigational capacity of wide-ranging animals such as albatrosses. Infrasound is a form of low-frequency sound that propagates for 1,000s km in the atmosphere. In marine habitats, its association with storms and ocean surface waves could in effect make it a useful cue for anticipating environmental conditions that favor or hinder flight or be associated with profitable foraging patches. However, behavioral responses of wild birds to infrasound remain untested. Here, we explored whether wandering albatrosses, Diomedea exulans , respond to microbarom infrasound at sea. We used Global Positioning System tracks of 89 free-ranging albatrosses in combination with acoustic modeling to investigate whether albatrosses preferentially orientate toward areas of ‘loud’ microbarom infrasound on their foraging trips. We found that in addition to responding to winds encountered in situ, albatrosses moved toward source regions associated with higher sound pressure levels. These findings suggest that albatrosses may be responding to long-range infrasonic cues. As albatrosses depend on winds and waves for soaring flight, infrasonic cues may help albatrosses to identify environmental conditions that allow them to energetically optimize flight over long distances. Our results shed light on one of the great unresolved mysteries in nature, navigation in seemingly featureless ocean environments.

“…This includes neurological sensors that may record the processed information of the animal; as seen in examples of 3D-space representation recording in bats ( Sarel et al, 2017 ; Yartsev and Ulanovsky, 2013 ) and olfactory sensory response recorded with electroencephalogram (EEG) on free roaming animals ( Whitford and Klimley, 2019 ). Further, animal-attached sensors can record aspects of the sensescape that a freely behaving animal is exposed to directly in naturalistic environments, including infrasound recorders onboard seabirds ( den Ouden et al, 2021 ), chemical sensors recording humidity and oxygen saturation (e.g. Wild et al, 2023 ) which may open the door to further chemical sensors relevant to olfaction (e.g.…”

Groups of animals inhabit vastly different sensory worlds, or umwelten, which shape fundamental aspects of their behaviour. Yet the sensory ecology of species is rarely incorporated into the emerging field of collective behaviour, which studies the movements, population-level behaviours, and emergent properties of animal groups. Here, we review the contributions of sensory ecology and collective behaviour to understanding how animals move and interact within the context of their social and physical environments. Our goal is to advance and bridge these two areas of inquiry and highlight the potential for their creative integration. To achieve this goal, we organise our review around the following themes: (1) identifying the promise of integrating collective behaviour and sensory ecology; (2) defining and exploring the concept of a ‘sensory collective’; (3) considering the potential for sensory collectives to shape the evolution of sensory systems; (4) exploring examples from diverse taxa to illustrate neural circuits involved in sensing and collective behaviour; and (5) suggesting the need for creative conceptual and methodological advances to quantify ‘sensescapes’. In the final section, (6) applications to biological conservation, we argue that these topics are timely, given the ongoing anthropogenic changes to sensory stimuli (e.g. via light, sound, and chemical pollution) which are anticipated to impact animal collectives and group-level behaviour and, in turn, ecosystem composition and function. Our synthesis seeks to provide a forward-looking perspective on how sensory ecologists and collective behaviourists can both learn from and inspire one another to advance our understanding of animal behaviour, ecology, adaptation, and evolution.

“…Finally, the development of biologging devices to capture avian movement along with infrasound measures will be crucial in advancing this field of research. Indeed, we have developed a miniature multidisciplinary sensor platform to collect geophysical data to investigate the use of infrasound and weather patterns in navigation decisions (den Ouden et al, 2021a). These techniques will improve our understanding of how seabirds use information from other geophysical cues at sea (e.g., wave direction; Lohmann and Lohmann, 1996;Serres et al, 2019), for which little is known.…”

Infrasound as a Cue for Seabird Navigation

Seabirds are amongst the most mobile of all animal species and spend large amounts of their lives at sea. They cross vast areas of ocean that appear superficially featureless, and our understanding of the mechanisms that they use for navigation remains incomplete, especially in terms of available cues. In particular, several large-scale navigational tasks, such as homing across thousands of kilometers to breeding sites, are not fully explained by visual, olfactory or magnetic stimuli. Low-frequency inaudible sound, i.e., infrasound, is ubiquitous in the marine environment. The spatio-temporal consistency of some components of the infrasonic wavefield, and the sensitivity of certain bird species to infrasonic stimuli, suggests that infrasound may provide additional cues for seabirds to navigate, but this remains untested. Here, we propose a framework to explore the importance of infrasound for navigation. We present key concepts regarding the physics of infrasound and review the physiological mechanisms through which infrasound may be detected and used. Next, we propose three hypotheses detailing how seabirds could use information provided by different infrasound sources for navigation as an acoustic beacon, landmark, or gradient. Finally, we reflect on strengths and limitations of our proposed hypotheses, and discuss several directions for future work. In particular, we suggest that hypotheses may be best tested by combining conceptual models of navigation with empirical data on seabird movements and in-situ infrasound measurements.
