This paper explores the potential of explainable artificial intelligence (XAI) in the field of bioacoustics. To analyze bird sounds, which show significant geographical variation across North America, we transformed acoustic signals into spectrogram images and trained a classification model using a deep convolutional neural network (CNN). To interpret the model's predictions, which achieved 94.8% accuracy, we applied XAI techniques such as LIME, SHAP, DeepLIFT, and Grad-CAM, and integrated the results from different techniques to obtain more complete and interpretable insights. We demonstrate that combining various XAI techniques can improve model reliability and interoperability, suggesting that this approach can be applied to other domain-specific tasks.
