Researchers within the Centre for Ornithology at the School of Biosciences are beginning to unravel the mysteries of where sooty terns go when they are not breeding on Ascension Island in the South Atlantic.
Tiny trackers, capable of sensing sunrise and sunset, are attached to the legs of sooty terns. When the terns are found on their return to the Ascension islands the trackers can be recovered and analysed to discover where in the world the birds have been in the intervening time which can be up to five years.
