A study of 100 papers from five journals that make use of bioacoustic recordings shows that only a minority (21%) deposit any of the recordings in a repository, supplementary materials section or a personal website. This lack of deposition hinders re-use of the raw data by other researchers, prevents the reproduction of a project's analyses and confirmation of its findings and impedes progress within the broader bioacoustics community. We make some recommendations for researchers interested in depositing their data.
