We tracked this coyote for some time. There had been heavy snow fall for much of the past 24 hours so he was keeping to the track where the going was easier, allowing us to photograph him low down and head-on.
One animal that has provided a large number of photographic opportunities in Yellowstone is the American Bison, the largest land mammal in North America. With males weighing in at up to 2000lbs these animals are massive and certainly not to be messed with.
Yellowstone is a beautiful but harsh environment in winter and only when you're here do you fully appreciate just how tough it must be to survive in these conditions. Top of my list for this trip was to see a Red Fox hunting and jumping, so I was very happy to get this one.
