As you drive along the roads in Yellowstone, you need to keep your eyes open for the bison, as they can suddenly appear and cross the road. While I was in Yellowstone recently, we had a number of stoppages due to bison crossing the road.

One of the more interesting aspects that I observed were bull bisons fighting. These were probably young males, learning how to fight, rather than bull seeking out females. The rut season for bison usually occur in late July and August.
Despite being the largest land animal in North America, bison a very agile and quick and are capable of reaching speeds and exits at 30 mph. Every year bisons to injure park visitors who approach to closely. The regulations of the park state that you should be at least 25 yards away from bison, elk and other animals.
This bull bison crossed from the other side of the gully and up toward us, while will were photographing it and started to give us "an evil eye", we all return to our van very quickly.
Calves are born, usually in late April and May. They usually have a cinnamon-colored coat which is shared and about two months. We did find some younger calf's with the cinnamon-colored coat even into September
Cows, calves and some younger bulls usually comprise a herd. Mature bulls will spend most of the year alone or with other bulls.
