It remains physically similar to the wild ancestors of domestic sheep, the Mediterranean mouflon and the horned urial sheep of Central Asia. It is much smaller than modern domesticated sheep but hardier, and is extraordinarily agile, tending to take refuge amongst the cliffs when frightened. Soays may be solid black or brown, or more often blonde or dark brown with buffish-white underbelly and rump (known as "lachdann" in Scottish Gaelic, which is cognate to the Manx "loaghtan"); a few have white markings on the face.
