The Hebridean is a breed of small black sheep from Scotland, similar to other members of the Northern European short-tailed sheep group, having a short, triangular tail.
Modern Hebrideans have black, rather coarse wool, which fades to brown in the sun and often becomes grey with age; there is no wool on the face or legs. If not shorn the wool may moult naturally in spring. Rams and ewes typically have one pair of horns, but often have two or even more pairs (polycerate), and occasionally none. They are considerably smaller than most other breeds of sheep, fully grown ewes weighing only around 40 kg (88 lb), and rams slightly heavier, at around 50 to 60 kg (110 to 130 lb). Hebrideans are hardy and able to thrive on rough grazing, and so are often used as conservation grazing animals to maintain natural grassland or heathland habitats. They are particularly effective at scrub control, having a strong preference for browsing.
