A study by Bangor University and The Royal Society for the Protection of Birds in the U.K has proven to be able to extract tidal information using tagged Razorbills on the Irish Sea. By comparing mathematical current model with the movements of resting birds on the surface waters, they found that the changing position of Razorbills whilst resting at night would reflect the movement of ocean surface waters. Although measuring tidal data using seabirds has limitations, it shows great potential for inexpensive methods in providing crucial oceanographic data and can have uses in the marine renewable energy industry.
