WABAD: A World Annotated Bird Acoustic Dataset for Passive Acoustic Monitoring

Original dataset available and full authors list: https://zenodo.org/records/17293588

Dataset corresponding author: Cristian Pérez Granados (cristian.perez@ctfc.cat), Esther Sebastián-González (esther.sebastian@ua.es)

Additional dataset curation: Ben McEwen (b.j.mcewen@tilburguniversity.edu), Corentin Bernard (corentin.bernard@lis-lab.fr)

Dataset Curation

The original dataset (available on Zenodo) is composed of mostly one-minute audio files (.wav) with corresponding Audacity and Raven Pro annotations corresponding to each individual audio file.

This curated version of the dataset has been adjusted for ease of use:

• —Segmented audio into 3-second files (.wav)
• —Multi-label annotations combined with site metadata in parquet files
• —Train and test splits (80/20 %) predefined by respective .parquet files

Segmentation Method

Raven Pro annotations onset/offset times were converted to a species list (column: species) and one-hot encoding (column: labels) for 3-second segment for which a minimum vocalisation length of 0.5-second is present within the segment. 3-second segments are non-overlapping.
