A scalable transfer learning workflow for extracting biological and behavioural insights from forest elephant vocalizations

Remote Sensing in Ecology and Conservation, Journal Year: 2025, Volume and Issue: unknown

Published: April 25, 2025

Abstract Animal vocalizations encode rich biological information—such as age, sex, behavioural context and emotional state—making bioacoustic analysis a promising non‐invasive method for assessing welfare population demography. However, traditional approaches, which rely on manually defined acoustic features, are time‐consuming, require specialized expertise may introduce subjective bias. These constraints reduce the feasibility of analysing increasingly large datasets generated by passive monitoring (PAM). Transfer learning with Convolutional Neural Networks (CNNs) offers scalable alternative enabling automatic feature extraction without predefined criteria. Here, we applied four pre‐trained CNNs—two general purpose models (VGGish YAMNet) two avian (Perch BirdNET)—to African forest elephant ( Loxodonta cyclotis ) recordings. We used dimensionality reduction algorithm (UMAP) to represent extracted features in dimensions evaluated these representations across three key tasks: (1) call‐type classification (rumble, roar trumpet), (2) rumble sub‐type identification (3) demographic analysis. A Random Forest classifier trained achieved near‐perfect accuracy rumbles, Perch attaining highest average (0.85) all call types. Clustering reduced identified biologically meaningful sub‐types—such adult female calls linked logistics—and provided clearer groupings than manual classification. Statistical analyses showed that factors including age significantly influenced variation P < 0.001), additional comparisons revealing clear differences among contexts (e.g. nursing, competition, separation), sexes multiple classes. BirdNET consistently outperformed when dealing complex or ambiguous calls. findings demonstrate transfer enables scalable, reproducible workflows capable detecting variation. Integrating this approach into PAM pipelines can enhance assessment dynamics, behaviour acoustically active species.
