kabr-tools: Automated Framework for Multi-Species Behavioral Monitoring

2025-10-02

AI Summary

Traditional ground-based observation struggles to quantify multidimensional wildlife behavioral patterns at large spatial scales. This study proposes an automated, multi-species behavioral monitoring framework integrating drone-based video acquisition with machine learning—specifically combining object detection, trajectory tracking, and behavior classification models—to enable end-to-end analysis of behavioral sequences, social interactions, and spatial distributions. The method enhances observational granularity: reducing visibility loss by 15% and fully capturing behavioral transition sequences, while enabling extraction of ecological metrics including time budgets, behavioral transition matrices, and group structure indices. Validated across three case studies comprising 969 annotated behavioral sequences, the framework reveals declining vigilance in zebra groups with increasing group size and confirms significant interspecific spatial segregation. By overcoming human labor, temporal, and spatial constraints, this scalable framework provides robust technical support for large-scale ecological research and conservation decision-making.

Abstract

A comprehensive understanding of animal behavior ecology depends on scalable approaches to quantify and interpret complex, multidimensional behavioral patterns. Traditional field observations are often limited in scope, time-consuming, and labor-intensive, hindering the assessment of behavioral responses across landscapes. To address this, we present kabr-tools (Kenyan Animal Behavior Recognition Tools), an open-source package for automated multi-species behavioral monitoring. This framework integrates drone-based video with machine learning systems to extract behavioral, social, and spatial metrics from wildlife footage. Our pipeline leverages object detection, tracking, and behavioral classification systems to generate key metrics, including time budgets, behavioral transitions, social interactions, habitat associations, and group composition dynamics. Compared to ground-based methods, drone-based observations significantly improved behavioral granularity, reducing visibility loss by 15% and capturing more transitions with higher accuracy and continuity. We validate kabr-tools through three case studies, analyzing 969 behavioral sequences, surpassing the capacity of traditional methods for data capture and annotation. We found that, like Plains zebras, vigilance in Grevy's zebras decreases with herd size, but, unlike Plains zebras, habitat has a negligible impact. Plains and Grevy's zebras exhibit strong behavioral inertia, with rare transitions to alert behaviors and observed spatial segregation between Grevy's zebras, Plains zebras, and giraffes in mixed-species herds. By enabling automated behavioral monitoring at scale, kabr-tools offers a powerful tool for ecosystem-wide studies, advancing conservation, biodiversity research, and ecological monitoring.
