A collection of bat echolocation calls recorded in Norway, stored in .zc and .wav formats. The Terrestrial Ecosystem Research Network's Data Discovery platform hosts the data, which was last updated on May 1, 2026. Each audio file contains embedded metadata such as collection date, GPS location, and species identification where available.
Use Cases
- Filter and download specific call files based on GPS location and date criteria mentioned in the description.
- Analyze bat species presence and activity patterns based on identified calls.
- Train or validate automated species identification models using the provided audio files and embedded metadata.
- Study multi-species interactions in recordings where calls from multiple species are present.
Strengths
- Files contain embedded metadata including GPS location and collection date, enabling spatiotemporal analysis.
- Includes both identified and unidentified calls, providing a realistic sample for model training.
- Data is hosted on a structured platform (TERN Ecoacoustic Recordings) with searchable filter options.
Limitations
- Some audio files contain calls from multiple species, but only one species may be identified, complicating analysis.
- Column-level documentation is absent; field semantics must be inferred after download.
- The total number of recordings and files is unknown, which may limit suitability assessment.
