Wow. THIS is nature photography. I'm curious how much time and stealth it took to get close enough for this. Even assuming a long lens, you had to get pretty close.
In response to your question about how close I was, I would guess I was probably a little over 100 feet away shooting at 400mm. These Bighorns are not all that hard to get close too but getting them on top of the rocks and getting good interaction and lighting all at once is special.
I was lucky because there was a group of photographers all photographing a herd of mountain goats, as the mountain goats veered off the rest of the group followed and went off to my right to follow the Goats. I was getting ready to follow the others when I saw a herd of sheep crest the hill, so I stayed put and the sheep came towards me and rewarded with this scene.
