Thanks. Now the story!
I was sliding along a ditch after another two fully aware that the wind was wrong. They moved off into the wood & gave a bark or two. The pair in the shot were out of my sight further down the hill & they ran the other way making them upwind of me. I gave them some time to settle then crawled back along the ditch & then into the Pine trees & just waited for them to reach the clearing. Thats when I got the shots. When I left they were grazing peacefully which is as it should be.
