Bat Echolocation Calls from Mexico with Embedded Metadata

Terrestrial Ecosystem Research Network's Data Discovery provides a collection of bat echolocation calls recorded in Mexico. The dataset includes audio files in .zc and .wav formats with embedded metadata such as collection date, GPS location, species identification, and contributor details. Users should note that some files may contain calls from multiple species, and in certain cases, only one of the present species has been identified.

Use Cases

• Filtering and downloading specific call files based on collection date and GPS location mentioned in the description
• Analyzing bat species presence and activity patterns based on identified and unidentified echolocation calls
• Studying bat biodiversity and community composition in Mexico using the acoustic recordings
• Developing or testing automated species identification algorithms using the labeled and unlabeled call data

Strengths

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

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
• Row count is unknown, which may limit suitability assessment
