A collection of bat echolocation calls recorded across the United States of America. The dataset includes audio files in .zc and .wav formats, with embedded metadata such as collection date, GPS location, species identification where available, and contributor details. This metadata is extracted to enable searchable filtering within the TERN Ecoacoustic Recordings dashboard.
Use Cases
- Analyze bat species distribution and habitat use based on GPS location data mentioned in the description
- Train or validate automated species identification models based on labeled echolocation call files
- Study temporal patterns in bat activity based on the collection date metadata
- Conduct biodiversity assessments by exploring identified and unidentified call recordings
Strengths
- Includes embedded metadata such as GPS location and collection date for each audio file
- Contains both identified and unidentified calls, providing a realistic sample of field recordings
- Files are available in .zc and .wav formats, which are common in bioacoustics analysis
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download
- Column-level documentation is absent; field semantics must be inferred after download
- Some audio files contain calls from multiple species, but only one may be identified, which could complicate analysis
