In 1821 Robert Louis Stevenson paid a visit to Eilean Glas on the island of Scalpay. During the trip his crew captured a great auk, which they took aboard intending to take it to a zoo. The auk escaped 'while being allowed to fly for exercise'. It was last seen off the Mull of Kintyre. 'This bird is thought to have been one of the last living great auks'.
