Sheep may safely graze - or not!

A clear sunny day suggested a walk around Dinas Island. It's actually a coastal promontory that remains joined to the mainland. Sheep had evidently been grazing the steep bracken-covered slopes and had churned up the path with their sharp hooves, but they were nowhere to be seen - perhaps had been moved off to better grazing inland.
However, at the highest point, Pen Dinas, where the end of the rocky headland rears high up above the surging sea, I ventured out to peer down and spotted, far below, what looked like tiny rice grains. The sheep had clambered down to seek out a perilous pasture at the very tip of the promontory. They are sure-footed, hardy animals but not immune to danger: very occasionally a casualty washes up on the rocks.
