Swedish Bat Echolocation Calls with Embedded Metadata

Sweden is the geographic scope for this collection of bat echolocation calls. The dataset includes audio files in .zc and .wav formats, with embedded metadata such as collection date, GPS location, and species identification where available. The Terrestrial Ecosystem Research Network's Data Discovery platform hosts the data, which was last updated on 2026-05-01.

Use Cases

• Analyze bat species distribution patterns based on GPS location metadata.
• Train automated species identification models based on recorded echolocation calls.
• Study seasonal bat activity based on collection date information.
• Filter and download specific call files for acoustic analysis based on contributor or species criteria.

Strengths

• Includes embedded metadata such as GPS location and collection date for each call file.
• Contains both identified and unidentified species calls, providing a realistic field recording scenario.
• Files are available in .zc and .wav formats, which are common in bioacoustics.

Limitations

• Some audio files contain calls from multiple species, but only one species may be identified, complicating analysis.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
