African Cape buffalo fording the Okavango River Delta. I took this from a boat in Chobe National Park in northern Botswana.
African buffalo have a democracy. When they are ready to travel, they will stand and turn in the direction they want to go. The majority of "votes" wins and the head female will lead the herd in the winning direction.
African buffalo are very aggressive and have a tendency to attack humans. They are very protective of each other and take care of sick and old members of the herd, shielding them from predators.
