Bat Echolocation Calls Recorded in Croatia with GPS and Species Metadata

A collection of bat echolocation calls recorded from Croatia, containing audio files in .zc and .wav formats. The dataset includes both identified and unidentified calls, with embedded metadata such as collection date, GPS location, and species identification where available. The data is provided by the Terrestrial Ecosystem Research Network's Data Discovery platform and was last updated on 2026-05-01.

Use Cases

• Train species classification models based on recorded echolocation calls.
• Analyze spatial distribution patterns of bats based on embedded GPS location data.
• Study temporal activity patterns based on the collection date metadata.
• Filter and explore acoustic data for specific species using the searchable dashboard.

Strengths

• Includes embedded metadata such as GPS location and collection date for each call file.
• Audio files are provided in both .zc and .wav formats, offering flexibility for analysis.
• Data is searchable and filterable via the TERN Ecoacoustic Recordings dashboard.

Limitations

• Some audio files contain calls from multiple species, with only one species 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.
