The Shiant Isles are a small island group lying in the Minch east of the Outer Hebrides off the north-west coast of Scotland. The site comprises three large islands and several small islands and skerries, lying about 6 km east of the island of Lewis. The islands are composed mainly of a basaltic sill and include various types of coastline, including sheer cliffs and boulder screes, both of which provide suitable nesting sites for seabirds. In summer, the Shiants are important for breeding seabirds, especially auks and Fulmar Fulmarus glacialis. In winter, the close-cropped turf of the islands supports a flock of Greenland Barnacle Goose Branta leucopsis. The seabirds feed outside the SPA in nearby waters, as well as more distantly elsewhere in the Minch.
