This dataset contains 22 wav files with 2hr-recordings of background noise with some seabird calls from Man and Horse (St Helena, South Atlantic Ocean) from 28 June to 25 July 2012. Recordings were obtained with a custom-built autonomous sound recorder. Seabird species that are likely audible in those recordings are Madeiran Storm Petrel Hydrobates castro (note that this species is genetically isolated and may be described as an independent species in the future, see Taylor et al. 2019), but their calls will be infrequent and faint as the recorder was placed on top of a towering 500 m cliff exposed to strong winds, and storm petrels likely only fly much farther down around that cliff. Other calls could be from Common Myna, St Helena Plover, and insects. The purpose of the recording was to assess the utility of long-term acoustic abundance monitoring for seabirds on St Helena (similar to Oppel et al. 2014).
