North Rona and Sula Sgeir

Site overview: The site is named after these two small remote islands in the North Atlantic, about 65 km from the island of Lewis in the Outer Hebrides, off the north-west coast of Scotland. Sula Sgeir is about 15 km west of the larger North Rona. Sula Sgeir is eroding from the sea spray that hits it so has very little soil or vegetation. The islands provide a well-placed nesting location for large numbers of seabirds which feed in the waters off the north coast of Scotland, including large numbers of petrels, auks, gulls and Gannets. It is one of only seven known nesting localities in the EU for Leach’s Petrel.
