The islands were inhabited until the late 18th century, when changes in land ownership and society made the old way of life no longer viable.

s. 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.Paul Stapp (2002) Stable isotopes reveal evidence of predation by ship rats on seabirds on the Shiant Islands, Scotland Journal of Applied Ecology 39 (5), 831–840. 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.
