Abstract The islands of St Kilda are remote, spectacular and alive with many thousands of birds. As the only dual-status UNESCO World Heritage Site in Britain, St Kilda has a unique standing as a reserve for nature and culture. This article describes the history, management, wildlife and visitor status of the archipelago. It focuses on the islands’ birdlife, including the major seabird populations, the endemic St Kilda Wren Troglodytes troglodytes hirtensis, spring and autumn migration, and Arctic and American vagrants.
