This dataset contains WAV recordings and PNG spectrograms of the African songbird Bangwa Warbler (Bradypterus bangwaensis). The PNG spectrograms were used to train and evaluate an automated ResNet18-based classifier, while the WAV recordings were used to create a custom BirdNET species‑specific model (BirdNET-Analyzer version). The dataset is organised into folders representing training, validation, and testing sets.
