Tape playback census was conducted, with repeat visits to a calibration site to calculate response rates. Previous storm petrel surveys have been carried out to different methodologies, but this is the only complete census of both islands using standard tape-playback methods. This is the most reliable census to date, and confidence limits are given for the Skomer estimate. However, data can be influenced by variation in response rates, and further investigation is needed to better understand this variation and associated error. All data is held within the report.
