Decoding Animal Behavior: How Biologging and Remote Sensing Are Changing Wildlife Studies
"Unlocking the secrets of the animal kingdom through advanced technology: a deep dive into biologging and remote sensing techniques."
For decades, understanding the intricate behaviors of animals in their natural habitats remained a formidable challenge. Traditional observation methods often proved inadequate due to the elusive nature of many species and the limitations of human presence. However, thanks to rapid advancements in technology, a new era of wildlife research has dawned.
Biologging and remote sensing technologies have emerged as powerful tools, enabling scientists to collect unprecedented amounts of high-quality data on animal movements, interactions, and physiology. These technologies, ranging from GPS trackers to accelerometers and camera traps, provide invaluable insights into the lives of creatures great and small.
This article delves into the fascinating world of biologging and remote sensing, exploring how these innovative techniques are revolutionizing the study of animal behavior. We will examine various types of loggers and sensors, discuss their applications in different research areas, and highlight best practices for data collection and analysis.
Methods and instrument impacts
Resource selection functions combined with biologging-derived data are described as the most widely used method for studying habitat use. Over the last six decades, researchers have reduced instrument effects through device miniaturization, sophisticated release mechanisms, and other technological advances. Yet devices can still affect animal physiology, behavior, and demography—the very measures they are used to study. A minimum reporting standard informed by research on instrument impacts is proposed to support animal welfare and data quality as biologging expands.
What are Biologging and Remote Sensing?
At its core, biologging involves attaching miniaturized tags to animals to record and relay data about their movements, behavior, physiology, or environment. These tags can either directly acquire information (e.g., accelerometers measuring activity levels) or emit a signal that requires a remote sensor for interpretation (e.g., GPS trackers).

- Remote Sensing: Using sensors to gather information about animals from a distance.
- Telemetry: A specific case of remote sensing that involves tracking signals emitted by animal-borne tags.
Recent work on animal behaviour
Nature’s animal behaviour research page describes a field spanning studies under experimental and natural conditions, as well as behaviourism and ethology. A Nature Communications listing dated April 1, 2026, highlights a systematic review and meta-analysis of unimodal and multimodal predation-risk assessment in birds. The listing says birds’ behavioural responses to predation risk could depend on the type and number of cues. Animal Biotelemetry describes its scope as research using telemetric techniques to understand physiological, behavioural, and ecological mechanisms.
Welfare and bias concerns
Biologging devices can affect tagged animals’ behaviour and thereby distort or bias study results, even as their widespread use has yielded insights into behaviour, movement, and physiology. A 2024 article on biologging and animal welfare argues that limitations must be overcome to realize the approach’s potential for assessing welfare in wild animals. A 2025 article proposes a registry, potentially managed by the International Biologging Society, the Animal Behavior Society, or the Association for the Study of Animal Behaviour. The proposed registry could record the expertise of biologists, veterinarians, and animal caretakers involved in biologging research.
Animal-borne devices as research tools
A 2025 article describes biologging as the use of animal-borne devices to study animals’ behavioural ecology, physiology, and surrounding environment. This framing positions biologging as a tool for examining both animals and the environments around them. The source does not provide a comparison of biologging with other methods or report comparative results.
Why Biologging and Remote Sensing Matter?
The data derived from biologging and remote sensing are instrumental in addressing diverse themes within behavioral ecology, offering quantitative assessments of animal behavior. These technologies are particularly valuable for monitoring species that are rare, cryptic, nocturnal, or inhabit inaccessible environments. By shifting the point of observation from the researcher to the animal, biologging minimizes disturbance and provides a more natural view of behavior.
From individual records to ecological insight
A 2020 article reports that GPS and accelerometer data from animal tracking devices can provide high and relatively equal sampling intensities of behaviour across instrumented individuals in a population. It describes biologgers as enabling discoveries about patterns, causes, and consequences of animal behaviour. The authors present examples of how biologging can deepen fundamental understanding of ecosystems and applied understanding of global-change impacts by enabling tests of ecological theory. A 2024 publication is identified as addressing how biologgers can help solve fundamental questions from individuals to ecosystems.
Connecting tracking to conservation
A 2026 article says that using multiple sensors can help explore animal–environment interactions and inform conservation and management. It describes biologging and biotelemetry as tools for generating robust, ecologically relevant, and management-relevant data, from identifying problems to testing solutions. A 2025 article argues that the biodiversity crisis, urbanization, habitat fragmentation, and climate change call for new ways to assess conservation impact. It presents animal biologging as a cost-effective method for monitoring biodiversity at its source, including tracked animals.
