Despite being partially derived from a long-tailed breed (the Scottish Blackface), Borerays display characteristics which group them with other
northern European short-tailed sheep. They are amongst the smallest sheep, with mature
ewes weighing and standing at the withers. though older individuals do not moult as easily and may require additional shearing. Fleeces are grey or creamy white on the body, though darker individuals occur whose colouring is similar to the
Soay sheep. Rough in quality, the wool is mostly used in the creation of
tweeds or
carpet yarns. A tweed is a rough-surfaced coarse cloth, typically made in Scotland. Its colour is a mix of flecked colours. The face and legs are wool-free and black and white, with the proportions varying between individuals. Both sexes of the Boreray display
horns, formerly sometimes more than one pair, but in the modern breed always only one pair. The horns on the ewes tend to be thinner than those on the males and while they curve they do not
spiral beyond 360 degrees. Mature rams can grow large, spiral horns which may be used for crafts such as making
shepherd's crooks.
Population In 1999 the population was estimated to be at less than 84, with 74 ewes. In 2002, there were between 92 and 100 animals, with 92 ewes and the male population estimated to be less than 7. In 2012, 204 ewes were registered in
herdbooks. Since 2012, sheep numbers have been increasing year on year; and in 2017 the
Rare Breeds Survival Trust (RBST) moved the classification of the sheep from 'Category 2: Critical' to 'Category 3: Vulnerable' as the number of breeding ewes was estimated to exceed 500. This data was collected from the herdbooks produced by breed societies, listing all registered sheep, and multiplying the number of registered sheep to account for non-registered sheep. However, in 2017 the
Food and Agriculture Organization of the United Nations estimated that there were 426 breeding ewes. == Use ==
