Acoustic approach as an alternative to human-based survey in bird biodiversity monitoring in agricultural meadows

S2 Table. List of bird species defined as meadow and farmland species. (PDF) S3 Table. Occurrence of a particular bird species. Table shows: the number of surveys in which species was observed, the number of recording sites in which species was observed, the number of detections by a recorder, the number of detections by a human-observer. (XLSX) S4 Table. List of bird species detected only by recorder and only by human-observer. (PDF) Acknowledgments We would like to thank Amie Wheeldon and Agata Staniewicz for language correction, and anonymous reviewer for helpful comments and suggestions.
