the slopes of Garbh Eilean, as well as significant numbers of guillemots, razorbills, fulmars, kittiwakes, shags, gulls and great skuas. Although St Kilda has more puffins, the sheer density on the Shiants is greater. Until 2016 the island had a population of black rats, which may originally have come ashore from a shipwreck. Analysis of their stomach contents showed that the Shiant rats did eat seabirds, but it was impossible to tell if they preyed on live birds or simply scavenged remains. These rats are now rare in the UK. On the Shiants their numbers have been controlled in and around the house for some time, and a comprehensive wildlife project has now extinguished the population.
