RSPB Mousa

Mousa is a small, wild island in Shetland, uninhabited since the nineteenth century. It is notable for having one of the UK?s largest storm petrel breeding colonies, many of which nest in the Broch of Mousa, a 2000-year-old Iron Age round tower. The diversity of the wildlife on Mousa is reflected in its many protective designations for breeding birds such as black guillemots and Arctic terns, as well as for th e harbour seals and the fascinating geology of the island.
