What small island lies to the south of the Isle of Man?

Calf of Man is a 2.50-square-kilometre (618-acre) island, off the southwest coast of the Isle of Man. It is separated from the Isle of Man by a narrow stretch of water called the Calf Sound.

Like the nearby rocky islets of Chicken Rock and Kitterland, it is part of the historic parish of Rushen and the current parish district of Arbory and Rushen. It has only two seasonal inhabitants. The word 'calf' derives from the Old Norse word kalfr which means a small island lying near a larger one. One can reach the Calf of Man by boat from either Port Erin or Port St Mary. Cow Harbour and South Harbour are the main landing places. The highest part of the island is in the west where an unnamed peak reaches 126 m (415 ft) above sea level.

Until 1939 the island was under private ownership by the Keig family, but the island was purchased by Mr F. J. Dickens of Silverdale, Lancashire, who then donated it to the National Trust for it to become a bird sanctuary. In 1951 the Manx Museum & National Trust, which became known as Manx National Heritage, was established. Manx National Heritage then rented the Calf from the National Trust for a nominal £1 per year until 1986, when ownership was transferred. In 2006 Manx National Heritage employed the charity Manx Wildlife Trust as the Calf Warden Service Provider, but it retains ownership.
