These black lambs live inside the stone circle at Avebury in Wiltshire. The National Trust volunteer explained they were there to crop the grass, but I think they're really there to give tourists something to photograph in front of the stones.
The mums have shaggy long hair, which I understand is more valuable as wool. Regular dense-wool sheep aren't worth shearing for their fleece.
This baby ran to get under the shade of one of the large stones, which were placed there by Neolithic peoples several thousand years ago in order to give their lambs a place to hide from the fierce Bronze Age sun. (The grass is really greener than that; I had to lighten it up in order to see the lamb.)
When walking through a field of sheep, you should mind where you step.
This lamb was taking a nap. He'd had a hard day, posing for all the tourists.
