Buffalo can be found in the Badlands (south of the ranch) and near the Blackfoot Camp.
Buffalo are very skittish and will flee when approached. There are a few quests where you are required to hunt them.
The American Buffalo (Bison) is a North American species of buffalo that once roamed the grasslands of North America in massive herds and became nearly extinct by a combination of hunting in the 19th century and introduction of bovine diseases from domestic cattle. Buffalo have shaggy, long, dark brown winter coat, and a lighter weight, lighter brown summer coat.
Great White BuffaloEdit
The white buffalo is a special animal that only appears during the Indian Hunters side quests. The white buffalo can be found south of the Ranch along with the common brown ones. It is easily spooked so be cautious when sneaking up on it. When you are close enough its best to shoot it in the head with a bow. Should you spook it simply leave the area and return until it respawns.
